Boat Anchor Selection Guide: Choose the Perfect Type & Size

When you buy a used boat, odds are it will come with an anchor, and with a new boat you'll usually get to choose an anchor for it. What if that old anchor you have on your new-to-you boat doesn't hold so well, or needs replacing? In any of those scenarios, you'll need to pick out a new anchor for your boat. There are more types of anchors that you dreamed of, and they're all different in how they perform in different anchoring conditions. And your anchor will need to be sized for your boat.

The type of anchor you choose depends on the predominant bottom types where you plan to sail, and what fits on your boat. Once you know the type, you get the perfect type and size of anchor from the length and weight of your boat using the manufacturers' recommendations.

On this page:

How does an anchor work, loads and forces on an anchor, anchor construction materials, most common anchor styles, how do i choose an anchor, what's in your anchor locker, picking the right anchor ground tackle.

Instead of getting overwhelmed, if you do a little research upfront on what you might need you can narrow down your choices and get the best anchor for your boat and where you use it.

While it may seem obvious at first glance, there are many mistaken assumptions about just how your anchor holds your boat to the bottom. It's important to understand just what your anchor does when it's holding your boat, so you know why you may choose one anchor or another.

All anchors dig into the bottom. Some have aggressive, plow-like forms or scoops which burrow in quickly, others have various hooks, spikes or protrusions designed to catch and hook as soon as the anchor is pulled.

Angle of attack provides holding power

The pulling force on an anchor is along the shank, and for an anchor to offer maximum holding power, it's crucial that the bulk of the load from the boat's pull is applied in this direction. If the pull is from the side, the anchor may break out. If the pull is from above the anchor, it definitely will.

Part of the role of the chain in your rode is to keep the rode flat on the bottom to make sure the loads from the boat are horizontal and along the direction of the shank.

Scope & chain provide angle and drag

Your anchor rode and how much scope you let out is as important to your choice of anchor to how well you hold. Chain has its own resistance to being dragged and adds extra holding, and as noted above, it also keeps the forces on the anchor from pulling it out.

The longer the scope, the better the angle of pull on the anchor. With a length of chain, the extra weight adds more holding the bottom, and a rope/chain rode gives extra shock absorption in the catenary of the rode.

You can learn more about how to select and install the right anchor rode by reading our detailed article here.

Orientation of anchors

Most modern anchors have a definite top and bottom, and will not set lying on their backs. These anchors flip and orient their blades down if they land the wrong way or break out. Many anchor designs dig in quickly with the anchor lying on its side, and may have roll bars or weights to keep them in a suitable setting orientation.

Some anchors, like grapnel anchors or the Bulwagga, had a radial symmetry and no true up or down. These don't need to reorient or right themselves. They will catch the bottom no matter how they lie, though not all the blades and hooks will help hold the anchor.

Good anchors will reset unnoticably

All anchors can break out and may get rolled as a boat swings at anchor and wind strength increases. An anchor's ability to reset is important. You don't want to drag long before your anchor sets again. With a good anchor, you won't even be aware it has broken out and reset, as it will happen quickly without your boat seeming to drag at all.

An anchor doesn't care at all about what kind of boat is on the other end of the rode, what it cares about is how much drag force is on the rode. A heavy boat in a light breeze may pull as hard on an anchor as a lighter boat in more wind. It's the force that counts, and you size your anchor by how much force you can expect to land on that anchor and rode.

Boat weight partially determines drag force

Your boat's weight is one of the two sources of drag force on your anchor. Heavier boats will pull more than light boats in the same condition. Many anchor vendors give tables of boat weight ranges which match to the best anchor size.

In wind, boat length is more important

Picture two boats with the same weight - a low-slung classic yacht with little freeboard , but a heavy full keel, and a more modern design with higher freeboard, less ballast, and about ten more feet of length. In windless conditions, they'll pull about the same against the anchor.

But in twenty knots of breeze, the longer boat with more freeboard will have a lot more pull. Here, the boat's length overrides the weight. A doubling of wind speed quadruples the load on the anchor, so this effect becomes more pronounced the higher the wind.

Anchors are made from three primary materials - galvanized steel , stainless steel , and aluminum .

Galvanized steel anchors are cheap

Galvanized anchors are the most common, as they are the least expensive, offer excellent weight, and are very durable and rugged. They can rust over time as the galvanization wears off, but provide the best cost to holding of all anchor construction material. You can re-galvanize an anchor at considerably less cost than replacing the anchor, if the original protection wears off.

Stainless steel anchors are expensive

Stainless steel anchors have similar strength to galvanized steel anchors combined with corrosion resistance. They look beautiful on the bow, but they are quite expensive at 3-5 times the cost of a similar galvanized anchor, and you'll want to pair them with a more expensive stainless chain. While they won't rust, they can get scratched and lose their shiny finish if you use them often. And there is a risk of crevice corrosion if stainless steel sits underwater too long.

Aluminum anchors don't rely on weight

Aluminum anchors are lightweight and strong, but may not have the holding power of heavier anchors of a similar size, and aluminum is not as strong as steel. They are popular with racers, and also for secondary anchors, because they are lighter and easier to handle. Aluminum anchors rely on bottom penetration to set, not weight.

The dozens of anchors available break down into a few general classes. Trying to organize all the choices by function helps you narrow the field to what may work best for you.

Claw anchor

Claw anchors, like the Bruce, have claw style blades to dig in and hold well for most conditions. They may struggle to dig in with a hard mud or clay bottom, but will reset well on other bottoms.

Plow anchor

Plow anchors are generally fixed, like the Delta, or have a hinge like the CQR. The fixed plows do well in everything but rocks, while the hinged CQR doesn't hold quite as well but responds better to the movement of the rode since there is a swivel.

Plow with Roll Bars

Modern designs like the Rocna and Spade incorporate a plow form on the blades, coupled with a roll bar. These have fantastic holding power and set easily. They don't fit as well on some older boats, and are more expensive.

Fluke anchor

The fluke anchors are great in mud and sand, but don't do as well with bottoms they can't penetrate or grass. The Danforth (and its clones) are popular with smaller boats, and the lightweight aluminum Fortress is a favorite with weight conscious ravers.

Fisherman's anchor

The traditional crossbar and hooks anchor is good for rocks. Some break down for storage, which makes them a popular choice for a storm anchor.

Grapnel anchor

Grapnels are fine anchors for dinghies, kayaks, PWCs and other small, light craft but don't do well with higher loads and larger boats.

Mushroom anchor

Small mushroom anchors can hold a small craft like a dinghy or kayak. Many permanent moorings are large mushroom anchors, where they can dig deep into the bottom. But they are not suitable for big boat use.

Other alternatives

This list isn't exhaustive. There is constant innovation in anchor technology, from the Bulwagga to various box anchors, which don't even look much like anchors as we think of them. All have their strengths and weaknesses, so research carefully and try to find someone with real-world experiences with them.

Remember, there is no "right" or perfect anchor, so look at a lot of options to see what fits your boating style.

The basic decisions you have to make about your anchor are the style, size, and material of your anchor. While we can't get into every type of anchor on the market and how it works for every boat, we can give you an overview of the decisions you must make.

What fits on your boat?

If you're adding a new anchor to an existing boat, you may have some natural limitations on what anchors you may choose.

With a bow roller sized for a plow or a nice Danforth bracket installed already, maybe those features limit your choices. You may switch between a CQR and a Delta with that anchor roller, but there's a good chance you can't fit a Rocna's roll bar up there without bending something. You could probably switch a Fortress out for a Danforth in that bracket, but you can not hang a plow from it.

Most anchor manufacturers give dimensional drawings of their products on their websites, so measure and even mock up something to see if it will go. On my boat, I shoved a Manson Supreme where a CQR went, but not without permanently bending a retaining pin. And I mocked the whole thing up in cardboard ahead of time to be sure.

Where will you anchor?

The range of where boat affects what to have in your bow locker. If you're a Chesapeake Bay sailor and you don't leave the bay, something that holds well in mud is a must and may be all you need. But a world cruiser needs something more effective across a range of bottom types.

Give careful thought to the places you’ll want to spend the night on your boat, especially the bottom types you'll find. In the end, you'll likely have more than one anchor, and you want to cover most of the holding types you'll encounter.

Choose your materials based on budget and style

This is a matter of budget and style, mostly. As a cruiser who spends almost every night at anchor, I can't see the sense of spending a fortune on a pretty anchor that spends most of its life hidden. But for some, adding that high gloss show to the bow of a Bristol condition yacht everyone can see most of the time, the aesthetic choice may make more sense.

When I raced, I had a Fortress because it met the requirements to have an anchor, but I ended up spending a couple of nights on it. It was easy to move around, but for vacations I still dragged the 35 lb. CQR out of the shed and put it in the bow locker.

Size your anchor based on boat length and weight

Sizing your anchor is most people's biggest worry. Remember, it's better to have too much anchor instead of not enough. You want to sleep soundly and leave your boat without worrying. If you're hauling your anchor up without a windlass, the extra pounds matter a lot more, but it's better to have extra.

It's not as hard as you think to size your anchor, because every single manufacturer publishes a guide to how to select the right product for your boat. Most of them have tables for boat length and boat weight, and we talked up above about how a boat's weight and windage affect anchor loads.

To size your anchor, follow these steps.

• Search the "by length" table for the length of your boat, and note the recommended size.
• Search for the weight of your boat, and note the recommended size.
• The correct anchor size for your boat is the larger of those two recommendations.

If they give a single number in the table, choose the next number above yours. If they use ranges and your boat is on the edge of a weight or length range, there's no harm in moving to the next size band. Don't move down bands; you don't want to undersize.

For an example, look at this sizing table for Spade Anchors. We've going to pick an anchor for a boat which is 53' long and weighs about 54,000 lbs.

Source: Anchor sizing chart on Spade Anchor USA

You'll see a boat length of 53' puts us at 59ft. and a 55 pound galvanized anchor. But by vessel weight, for 54,000 lbs., the recommended weight is 99 pounds.

So the larger of the two is 99 lbs., so that is the proper weight for this boat.

Most boats should have more than one anchor, so you will go through this process several times. You may need multiple anchors for the different bottom conditions you may come across. If you foul an anchor or lose one, a spare anchor and rode can literally be a lifesaver.

Other reasons for multiple anchors include a lighter anchor for a "lunch hook," though with an electric windlass this isn't much of a concern on bigger boats. You may want a smaller stern anchor in case you need to anchor where you don't want to swing, or it's important to keep your bow facing a direction other than into the wind. And finally, if you plan to cruise far from your home port, you may want a storm anchor.

Any of the anchor types we've discussed will fill many of the above roles, and you can use these tools to evaluate your boat and your plans to make the best choice for each job.

The next step is to select the right ground tackle. Ground tackle consists of everything that connects the anchor to your boat and is used to control the angle of attack, scope, and drag by adding or removing weight to the anchor.

I've written a detailed guide to help you to understand ground tackle in depth , which will help you select the perfect parts yourself.

Anchor Selection Guide: How to Choose the Best Boat Anchor Type

There are a number of boat anchors available, constructed of different materials, and often with confusing names. This article will discuss the most popular types of boat anchors,  how to choose the best anchor for your boat, the most common material types, and also give an overview of different naming conventions.

Quick Anchor Style Summary

Video: Choosing an Anchor Type

Our video below introduces many of the anchor types discussed here, although the article discusses a few more anchor types and provides some useful links.

Quick Summary Boat Anchor Recommendation

For most boaters , a Bruce or Delta is the best balance between price and performance. Both perform similarly and are similarly priced (Narrowly, the Bruce/Claw is our favorite of the three). If you've used a Danforth in the past , and you have had luck with it, choose a Danforth. If you've never used one before and if your setup allows it, choose a Bruce or Delta instead. If you're a blue-water cruiser , choose a CQR, or consider one of the new generation of anchors discussed below.

Boat Anchor Names: Trademarked Names and Generic Names

A special note is needed on the naming of anchors. Many anchors have a trademarked name, such as a   Bruce   or CQR, and a generic name like Claw or Plow. This is the same as how Xerox is a trademarked name for photocopier and how Aspirin is a trademarked name for pain killer. Trademarks effectively never expire whereas design patents expire after approximately 20-25 years. Therefore, manufacturers are free to clone an anchor design that has an expired patent but cannot use the trademarked name.

Bruce™ Claw Anchor

The   Bruce, or Claw, remains one of the most popular anchors among recreational boaters in North America. This is our anchor of choice as well.

The   Bruce   was developed in the 70s by the Bruce Anchor Group. Once their patent expired in the early 2000s, they stopped production of this anchor but many imitations have come along since.

The  Bruce  is an excellent all-purpose anchor as it performs well in most sea bottoms including mud, sand, rock, and coral. It has a harder time penetrating harder surfaces, such as clay, and bottoms with heavy grass. The three-claw design sets more easily than other anchors. It also resets easily if it is ever broken loose. On the downside, the Bruce has a lower holding power per pound than other anchors, meaning you’ll usually need a larger anchor than say the  Delta/Wing .

Pros:  Performs well in most conditions. Sets easily. Cons:  Awkward one piece design. Lower holding power per pound. Bottoms: Performs well in most bottoms; Struggles in hard bottoms such as clay, or heavy grass.

CQR™/Plow   &   Delta™/Wing Anchor

Both the CQR/Plow and the Delta/Wing are a plow style anchor. The most significant difference between these anchors is the fact that the CQR has a hinged design whereas the Delta is a one piece design.

The   CQR   is one of the oldest styles, dating back to the 30s and to this day, it remains one of the most popular anchors among blue water cruisers. Despite this, it has relatively low holding power and it consistently struggles in independent tests. It’s also rare to find a CQR under 25 lbs lending itself to the saying “There’s no such thing as a small CQR”. Despite these shortcomings, the hinged design makes it more responsive to wind and tide changes as compared to other anchors.

The   Delta   is arguably the most popular anchor on boats today, and is the standard anchor of choice used by most boat manufacturers. It has a good holding power per pound (about 50% more than the Bruce).

Both the   Delta   and the   CQR   perform well in most bottoms, struggling the most in rock.

Pros:   Performs well in most conditions. Fits most bow rollers. Cons:   Hinged design can make stowage awkward. "No such thing as a small CQR/Plow anchor". Bottoms : Performs well in most bottoms; struggles in rock.

Danforth™/Fluke Anchor

The  Danforth , or Fluke anchor, remains a very popular anchor choice. The Fortress is also a popular Fluke style anchor, different from the  Danforth  in that it comes apart and it constructed of light-weight, high-strength, aluminum.

The Fluke performs well in mud and sand, potentially the best of any anchor style. The downside is that outside of these bottoms, it is not a good performer. Therefore, it is a mud/sand only anchor, which fortunately is what most bottoms are comprised of.

Whether or not it is used as a primary anchor, a Fluke anchor makes an excellent choice as a secondary or stern anchor.

Pros:  Performs well in mud and sand. Stows easily on most bow rollers. Cons:   Does not perform well outside of mud/sand. Bottoms : Top performer in mud/sand. Performs poorly in other bottoms.

Spade Anchors

There are several anchors on the market today that feature a sharp fluke and a roll bar. These include the   Rocna and Manson Supreme.

Each of these anchors are essentially a variation on a plow style anchor. If you look at the plow portion of these anchors, you can see they are a lot sharper than traditional plows like the   Delta/Wing   and CQR. Analogous to a knife through butter, these anchors can penetrate the sea bottom a lot easier and deeper than the other anchor styles, hence the name for these anchors: "spade". The roll bar helps orient the anchor upright when setting.

These anchors have performed   extremely well in third party tests . The biggest downside to these anchors is that because they are still patented, they can be very expensive. The roll bar along with the elongated fluke can also make storing these anchors on bow rollers difficult.

Pros:   Very high holding power for many models. Cons:   Difficult to stow on a bow roller. Expense. Bottoms : Performs well in most bottoms; less effective in rock

Grapnel   and Other Small Craft Anchors

A  Grapnel anchor  is generally used for small boats such as Kayaks, Dinghies, Canoes, etc. It’s also popular with fishermen.They fold up very compactly and are easy to stow. A Grapnel’s holding power comes from hooking onto another object, such as a rock. When it does hook, it can create immense holding power, which can also make retrieving the anchor difficult.

Pros:  Great for use as a lunch hook. Folds to allow for compact storage. Cons:  Not appropriate for non-temporary anchorage. Bottoms: Rock or other situations when it can hook onto an object.

Mushroom Anchors

Large Mushroom anchors  are often used for permanent mooring buoys. As the silt from the sea-bottom builds up over these anchors, it can result in extreme holding power, up to 10 times the holding power of its actual weight. As a mooring buoy, the mushroom anchor is an excellent choice, however, it is not as useful in some temporary anchoring situations. An exception is that smaller versions of these anchors are good for use in small boats for anchoring while fishing or for a lunch stop over silty bottoms where the mushroom can penetrate.

Pros: If large, great for permanent mooring buoys. If small, good for use while fishing or for a lunch stop. Cons: If large, not appropriate for non-permanent moorings. If small, only good in soft bottoms. Bottoms: Silt, soft mud, unpacked sand.

Boat Anchor Material Types

Boat anchors come in a variety of types, the most popular being mild steel, high-tensile steel, stainless steel, and aluminum.

Most of the traditional steel anchors we are accustomed to seeing are likely either mild or high tensile steel. Mild steel and high-tensile steel are nearly indistinguishable from one another appearance wise. However, high tensile steel is 2-3 times stronger than mild steel. This isn't to say that a high-tensile steel boat anchor has 2-3 times the holding power of its mild steel counterpart, but it will nonetheless be stronger.

Both mild steel and high-tensile steel anchors are not corrosion resistant, and therefore need to be galvanized to prevent rust and other corrosion. All steel anchors (except stainless) should be galvanized. Galvanization has a tendency to wear down over time, but an anchor (as well as nearly any other steel product) can be re-galvanized.

Stainless steel is identical to galvanized steel in terms of holding power but differs significantly in appearance. The shiny gloss is essentially the only difference between stainless steel and galvanized steel. Stainless steel is also very corrosion resistant and will resist most rusting over time. You will often see manufacturers describing stainless steel as either 316 Stainless or 304 Stainless. 316 is a different chemical composition than 304 and is more corrosion resistant. It also more expensive.

There are some anchors constructed from high strength aluminum, such as the Fortress. These anchors are extremely lightweight while still offering high holding power. These anchors rely on bottom penetration for most of the holding power, and therefore, if they are not set, they provide little to no holding power.

Boat Anchor Types: A Complete Guide

Table of Contents

To live out your boating dreams, it is important to ensure your  safety  and ensure that you have the best anchor. Anchors are essential for any boating activity and crucial for any experienced or amateur boater. By mastering the fundamentals of safe anchoring, you will safeguard your boating experiences from any accidents or anxiety. This guide will help you choose your ultimate anchor and provide tips for choosing which boat anchor is right for you. After choosing the anchor that is your right fit, you will be able to have smooth sails ahead and enjoy a stress-free time with friends and family.

Knowing the Ropes

Knowing your whole anchor system will be essential in shopping for an anchor. The anchor system is comprised of the chain, rope, shackle, and deck cleats along with the anchor. Each of these items must deliver the quality, performance, and strength that you need to anchor your boat .

Your Anchor Line: The Anchor Rode

Using a short anchor chain and three-strand nylon line will greatly reduce loads of shocks on your boat and the anchor system. Nylon is very elastic and helps reduce shockwaves or damage to the boat. Avoid anchor rodes that use all chains because they will lack the shock-absorbing qualities of nylon rope when the winds increase. The chain protects the line from chafing on the seabed.

If regularly anchoring in 25-ft of water or less, use 6 ft of chain. In greater depths, use an additional 6 ft for every 25-ft of water depth.

Holding Power

You have to make sure that the  anchor  you choose will support the boat you are operating and will fit the conditions of the environment you will be boating in. Choosing the right anchor for the type of boat you operate and the type of wind conditions you will be encountering is essential for boating safely. You must be certain that your anchor will be able to hold your boat. Here are three different types of anchors and rules of thumb for the durability of an boat anchor.

• Lunch Hook:  This anchor should hold a boat in a 15- knot breeze.
• Working Anchor:  This anchor should hold up to 30-knots of wind.
• Storm Anchor:  This anchor is for winds up to 42-knots of wind.

It is important to remember that as a general rule, when the wind speed doubles, the holding requirement quadruples. Be mindful of holding power requirements for different wind speeds, and use this information as a rule of thumb!

Know Your Scope

The scope is the length of the anchor line in relation to the distance of your boat’s deck to the bottom of the sea. Understanding scope is critical in anchoring and boating safely. The scope’s ratio should at least be 5:1, length to distance. When the scope increases, the anchor’s horizontal pull will also increase, which can help dig the anchor deeper into the sea bottom. When the scope decreases, the anchor’s pull will become more vertical. This can cause your boat to disturb and dislodge your anchor, especially at the height of a wave or during high tide.

If the scope’s ratio is less than 3:1, you are at risk of giving away a significant amount of control. Remember to set your anchor at a 5:1 initially. Afterward, you may shorten the scope as needed.

Power Setting the Anchor

To ensure that your anchor is thoroughly buried into the sea bottom, it is best to “Power Set” it. When you start setting the anchor into place, begin to lower it slowly into the water. As the anchor begins to descend deeper into the bottom, slowly begin to increase your anchor load with your engine to make sure it is securely buried. Remember that if you back off at any speed, you might not give the anchor a chance to bury itself into the sea bottom and ensure anchoring. You can follow and mimic the force of the wind by using the engine’s thrust to set the anchor to a predetermined load. By matching your boat’s total maximum horsepower and hull type , you can determine to what extent your boat can “Power Set” your anchor.

Anchoring in Soft Mud Bottoms

If you are anchoring in a soft mud bottom, this will greatly reduce your holding power compared to harder soils or sands. If you encounter a problem setting your anchor in this environment, then try setting the anchor at a very short scope at first. This initial scope could be a 2:1 ratio. When the anchor begins to dig in and set, slowly increase the scope to a greater ratio. An example of this could be a 5:1 ratio. Then, try to power set the anchor.

Special “mud palms” can be installed on your anchor, and it is recommended that you permanently install these “mud palms” to set your anchor in any type of bottom.

Retrieving the Anchor

Start by slowly moving the boat into a position that directly hovers over the anchor, pulling in the line as you go. When you are directly above it, shorten the line on a cleat and slowly power backward to pull the anchor out of the bottom. Do not power forward since this will require way more energy and put heavy loads on the anchor and support system.

A Summary of Anchor Types: Choosing the Right  Style  for You!

Claw anchors.

The Claw Anchor is one of the most popular anchors among boaters in North America. This anchor is a dynamic anchor that performs well in many sea bottoms, including mud, sand, rock, and coral. It has more trouble digging into harder surfaces like clay and dense grass. It has a three-claw design and sets and resets easier than other anchors. On the other hand, it has a lower holding power per pound than other anchors.

The Wing and Plow Anchor

The Wing Anchor is a hinged anchor. The Plow Anchor also has a hinged design, but the greatest difference between the Plow and Wing is that the Wing is a one-piece design. The Plow Anchor is one of the most popular anchors among bluewater cruisers despite having low holding power. However, the hinged design makes it more responsive and durable to environmental elements.

Delta Anchor

This anchor is an excellent choice for anchors that are going to be used repeatedly during stormy conditions. The self-righting design allows it to set quickly and the ballasted tip ensures that it stays in place. The Delta anchor can be said to be the most popular anchors among boats today and is the standard for boat manufacturers . Regardless of whether you want a boat anchor for a sailboat or for a pontoon boat, be sure to choose this one.

The Fluke Anchor

The Fluke Anchor is also a popular choice among boaters. The Fluke Anchor is constructed of lightweight, high-strength aluminum. The Fluke Anchor performs well in mud and sand, perhaps better than any other style. On the other hand, if not in mud or sand, The Fluke Anchor is not the best performer.

The Plow Anchor with Roll Bar

There are several Plow Anchors with roll bars that are essentially variations on the plow style anchor. The Plow Anchors with roll bars are a lot sharper than traditional Plow styles. Since the roll bars create a distinct sharpness, they can penetrate the sea bottom much easier than other anchor styles. The roll bar also helps the anchor orient itself when setting. The only downside is that these anchors can be very expensive and difficult to store.

Grapnel and Small Anchors

The Grapnel Anchor is used for small boats such as Kayaks, Canoes, etc. It is a favorite among fishers and is compact and easy to store. Grapnel’s hook onto another object for holding power yields immense holding power but can create difficulty retrieving the anchor.

Mushroom Anchors

Mushroom Anchors are often used for mooring buoys permanently because of their extreme holding power that can often hold ten times its actual weight. Silt from the sea bottom builds up over these anchors and results in this extreme holding power. However, this anchor type is not useful in temporary anchoring situations and makes more sense for permanent mooring. The exception is smaller versions of the Mushroom that can be used for small boats and anchoring while fishing.

Anchor Materials

The most common anchor materials are mild steel, high-tensile steel, stainless steel, and aluminum. Most anchors are mild/high-tensile steel. High-tensile steel is about twice as strong as mild steel, but that is not to say that it has a higher holding power, just that it is stronger. These are not corrosion resistant and need to be galvanized to prevent rust. All anchors need to be galvanized and can be pre-galvanized to prevent erosion.

Once you identify your needs and what fits best for you and your boat, you will be able to safely anchor at any desired destination!

There are a plethora of types and brands to choose from. Here's a guide to help you select the best one for your needs.

All anchors are designed to hold your boat in place by using the weight of the anchor, hooking the bottom, burying into the bottom, or a combination of all three. That said, choosing the right one relies on a number of considerations, from the style and size of your boat to the type of bottom you'll be anchoring in (e.g., mud, grass, sand, rock), as well as wind and water conditions you expect to encounter.

While an anchor's weight is important, even more so is its holding power. A modern, well-designed lightweight anchor can provide significantly more holding power than a heavy, older model that relies more on weight than design. Here's a list of common anchor types, uses, and pros and cons.

Narrow fluke, hook-type anchor relying on weight as much as how deep the flukes dig in. The traditional or fisherman's anchor (also called yachtsman anchor) is a good example.

• Versatile choice for a wide variety of bottoms depending on the width of its flukes: Narrow flukes best for rock, coral, grass, hard sand. Wider flukes (often called Herreshoff anchors) better in medium to hard sand and clay bottoms
• Doesn't perform well in soft sand or mud
• Awkward to stow, though modern take-apart versions make stowage easier
• Can trip with current/wind reversal
• The "lazy" fluke can foul the rode during tide or current shifts

Burying-style anchor relying on broad flukes rather than weight for holding power. Traditional Danforth anchors and newer Fortress Marine anchors are ­popular examples.

• Large flukes hold well in clay, mud, sand
• A pipe-like stock keeps anchor from twisting and pulling out as boat shifts
• Lighter design is attractive. Popular choice for boats with dedicated anchor locker (bow riders, midsize and larger fishing boats), or those with ample on-deck storage or bow roller
• Less effective in rock and grass
• Can be difficult to retrieve once fully buried
• If direction of pull goes past 180 degrees, it likely will break free (and usually reset itself in the new direction)
• Awkward to stow on deck with lots of angles to snag lines and toes

A stockless, single-point anchor named after its shape, which resembles a farming plow. Either a hinged or solid shank. Popular examples: CQR (a name derived from "secure"), Rocna, Delta, and Manson Supreme.

• Performs well in sand, stiff mud, shell, mud/gray clay
• Many consider it the ideal overall anchor for vessels larger than 30 feet. Not the best in any one type of bottom, holds well in all
• Easiest to stow and deploy on boats with bow roller and dedicated anchor locker
• Holding can be marginal in bottoms with moderate to heavy grass.

While similar to the plow, instead of single-point penetration, claw anchors have a scoop design. Bruce and Lewmar are good examples.

• Performs well in varied bottoms (sand, mud, light grass, etc.)
• Not ideal for rocky bottoms
• Due to size and weight, claws are more easily stowed and deployed on boats with bow roller and dedicated anchor locker

Similar to those nifty clawed hooks ninjas use to climb palace walls in the dead of night, grapnel anchors typically have at least four large arms or flukes. Spike or "grabber" anchors (a variation of the grapnel) typically have five or more shorter, fixed spikes or prongs attached to a centrally weighed shaft or base.

• Popular choice for smaller craft (e.g., dinghies, kayaks, PWCs.) due to light weight and ease of stowing. Most have folding arms and can be tucked away
• Works best on rocky or weedy bottoms where arms have something to hook
• Particularly useful in heavy vegetation where one or more flukes can penetrate the bottom while the outside ones hook into the vegetation
• Poor performer in sand and mud
• Considered only a temporary anchoring solution

With its shape-derived name, the box anchor is a square unit with eight angled flukes (four per side, two each at front and back) providing holding power by maximizing surface area contact with the bottom. Once deployed, the anchor's scoop design allows the narrow panels to set cookie cutter-like into muddy bottoms.

• Popular with pontoon owners, it requires no chain, sets quickly, retrieves easily, folds flat for storage
• Easier to use than many other anchor styles when deployed. Harder to handle and stow onboard
• Not good for long-term anchoring. When anchoring in areas subject to strong current, high wind, or waves, it can tip forward releasing the back "teeth," reducing holding power.

Named for its shape, resembling an upside-down mushroom, the holding power comes from the weight and the bottom suction generated once buried. Often used as mooring anchors. Models designed as boat anchors (vice moorings) will have holes or slits in the circular bowl or "cap" area to help release this suction and make retrieval easier.

• Works best in silt or muddy bottoms
• Ideal for canoes, jon boats, other small craft
• Not good for bottoms where it will have trouble burying itself (rock, weeds, hard sand)

Derived from the mushroom anchor and similar in shape, it has broad flukes rather than a simple bowl-shaped mushroom cap. These flukes (with rounded, rather than pointed ends) allow the anchor to grab, hold, and penetrate the bottom better than regular mushrooms.

• Works well in soft bottoms, but in a pinch can give decent service on rougher bottoms (e.g., weeds, rock)
• Like the mushroom, good for use aboard canoes, jon boats, similar small craft
• Not suitable for larger boats
• Not suitable for extreme or long-term anchoring. Should only be used for short-term anchoring under moderate conditions

Anchor Pole

This flexible "spike" lets you silently "spud down" over your favorite shallow-water anchorage (8 feet or less). It's deployed via a folding hydraulic arm. One anchor pole can hold you in place, but installing two allows you to temporarily position the boat regardless of prevailing wind and current directions.

• Typically found on bass boats. Can be installed on most any fishing boat anchoring in shallow waters
• Not suitable for extreme or long-term anchoring. Should be used short-term under moderate conditions only

How To Anchor A Sailboat – (All Types)

Anchoring a sailboat, whether in the serene embrace of a secluded cove or the challenging conditions of open waters, is both an art and a science. Sailors must navigate an array of factors—from the type and size of their vessel to the nature of the seabed and the temperament of the waters. This comprehensive guide delves into the intricate world of anchoring sailboats of all types and sizes. We’ll explore the varied types of anchors and their specific uses, highlighting why there’s no one-size-fits-all solution when it comes to securing your vessel. Whether you’re a seasoned sailor or new to the helm, understanding the nuances of anchoring in different water conditions, such as rough or deep waters, is essential for safe and enjoyable sailing.

Different Types of Sailboats and Anchoring Needs

The anchoring requirements of a sailboat vary widely depending on its type and size. Smaller boats like dinghies require lightweight, easy-to-handle anchors, while larger vessels like cruising yachts necessitate robust anchoring systems due to their higher windage and weight.

• Dinghies and Day Sailors : These small boats need compact, lightweight anchors that are easy to store and deploy. Their low weight and windage make them less demanding regarding anchoring power.
• Cruising Yachts : Larger and heavier, these boats require anchors with significant holding power. The choice of anchor must account for a wider range of wind and tide conditions.
• Racing Boats : Often similar in size to cruising yachts but with different design considerations, racing boats may require specialized anchoring equipment that combines strength with minimal weight.
• Multihull Boats (Catamarans, Trimarans) : Their wide beam and different weight distribution call for larger anchors or specialized systems to ensure stability and security.

Choosing the right anchor for your sailboat involves understanding these differences and balancing factors like weight, holding power, and ease of use.

Exploring Different Anchor Types and Their Uses

The world of anchoring is diverse, with each anchor type designed for specific conditions and seabed types. Understanding the strengths and ideal uses of various anchors can greatly enhance a sailor’s ability to move securely moor in different environments. From traditional designs to modern innovations, the choice of anchor depends on factors such as the boat’s size, the nature of the seabed, and prevailing weather conditions.

Fluke (Danforth) Anchors

• Ideal for small to medium-sized boats.
• Best suited for soft sea beds like mud or sand.
• Offers high holding power relative to its weight.
• Easy to store due to its flat design.
• Less effective in rocky or very hard seabed conditions.

Plow Anchors

• Versatile and suitable for larger vessels.
• Performs well in various seabeds, including mud, sand, and grass.
• The plow shape allows it to dig in and hold securely.
• It can be more challenging to store due to its shape.
• Offers reliable performance in changing conditions.

Bruce or Claw Anchors

• Known for their ability to reset quickly if dragged.
• Works well in rocky, sandy, and weedy seabeds.
• Ideal for areas with strong winds or currents due to its resetting capability.
• The design provides consistent performance but with moderate holding power.
• Popular among boaters for its all-around functionality.

Rocna or Manson Supreme Anchors

• Designed for quick setting and reliable holding in diverse conditions.
• Heavy-duty construction makes them suitable for larger boats.
• Effective in various seabed types, including hard and soft conditions.
• Offers high holding power, reducing the likelihood of dragging.
• They are increasingly popular due to their robust performance across various environments.

Each of these anchor types has unique characteristics that make them suitable for specific conditions and boats. Sailors should consider these factors when selecting the right anchor for their vessel, ensuring safe and effective anchoring.

Anchoring Techniques for Challenging Conditions

Anchoring in challenging conditions demands skill, preparation, and the right equipment. In rough waters, the primary concern is the anchor’s ability to maintain its hold despite strong winds and waves. Using a heavier anchor or a larger size than usual can provide additional security. It’s also crucial to pay out more scope (the ratio of the length of the anchor line to the depth of the water) in such conditions, typically at least 10:1. This ensures that the pull on the anchor is more horizontal, reducing the chances of it being dislodged.

Setting two anchors in a V-configuration in strong currents or winds can offer greater stability. This technique involves deploying two anchors from the bow at 45-degree angles, creating a wider support base. Regularly checking your anchor’s position using landmarks or electronic aids like GPS is vital to ensure it hasn’t dragged.

Finally, it’s important to be mindful of the seabed composition. In challenging conditions, anchors designed for specific bottom types (mud, sand, rock) can provide better hold. If the anchor does start to drag, being prepared to quickly reset it or deploy a secondary anchor can prevent dangerous situations.

Deep Water Anchoring – Techniques and Considerations

Anchoring in deep water presents unique challenges. The increased water depth requires more anchor rode to achieve an adequate scope. In deep waters, a scope ratio of at least 5:1 is often necessary, though conditions may dictate even more. The increased length of rode, however, increases the swing radius of the boat, which needs to be considered, especially in crowded anchorages or near underwater hazards.

The type of anchor rode is also a key consideration in deep water. All-chain rodes are preferred due to their added weight, which helps maintain a more horizontal pull on the anchor, which is crucial for good holding power. However, the weight of the chain can be a concern for smaller boats or those with limited storage capacity. In these cases, a combination of chain and rope can be used.

Lastly, when anchoring in deep water, it’s essential to use an anchor with a proven track record of setting and holding in various seabed types. The increased depth means retrieving and resetting a dragged anchor can be more laborious and time-consuming, making a reliable initial set even more critical.

How Do Different Bottoms Affect Anchoring? Multiple Types

The composition of the seabed is a crucial factor in anchoring. Different anchors are designed to perform optimally in specific bottom types, such as mud, sand, gravel, or rock. In muddy bottoms, anchors that can dig deep, like the plow or scoop anchors, are effective. These anchors bury themselves into the soft substrate, offering a stronghold.

In sandy conditions, fluke anchors are often the best choice. Their design allows them to penetrate the sand easily and provide a secure hold. However, these types of anchors might struggle in rocky or coral bottoms. Claw anchors, with their ability to reset themselves and grip onto uneven surfaces, can be more suitable in these conditions.

Seagrass beds present another challenge. Anchors can have difficulty penetrating the grass and reaching the underlying sand or mud. In such cases, a heavier anchor that can cut through the vegetation or a design that allows for a more direct downward force, like a Bruce anchor, may be more effective. It’s also essential to be environmentally conscious when anchoring in seagrass to avoid damaging these vital ecosystems.

5 Tips and Tricks for Anchoring Your Sailboat

Experienced sailors know that effective anchoring is as much about technique as it is about the right equipment. Advanced techniques can make a significant difference in challenging situations.

• Setting a Stern Anchor : This can stabilize the boat in strong tides or winds, preventing it from swinging too much.
• Tandem Anchoring : Placing two anchors in line increases holding power in strong winds or currents.
• Using a Trip Line : In rocky or coral bottoms, a trip line attached to the crown of the anchor can help in retrieving it if it becomes snagged.
• Anchor Bridle on Multihulls : Using a bridle system can distribute the load evenly and reduce strain on a single hull for catamarans and trimarans.
• Anchor Watch: Regularly monitoring the boat’s position manually or through electronic systems like GPS ensures the anchor hasn’t dragged.

Implementing these techniques requires practice and understanding of the specific conditions and the type of anchor being used. Each approach has its place, and knowing when and how to use them is the mark of a skilled sailor.

In Conclusion

When it comes to anchoring your sailboat or any other type of boat there are a lot of things to think about. This article talked about many different types of anchors and their pros and cons. I also mentioned how the bottom of the ocean or lake needs to be considered when you are trying to anchor somewhere. You need to take time and insect the sea floor if possible and consider the best technique for anchoring. I hope this article helps you on your next adventure! Cheers!

4 Popular Types of Sailboat Anchors

• August 9, 2022

Sailboat anchors are a frequently overlooked yet necessary item, and it might come as a surprise that many new boats do not come with one. As such, it is usually a boater’s next purchase before going out and spending time on the water.

Unless you are a seasoned skipper, choosing the right type of anchor can be overwhelming as there are several styles, each with its pros and cons. Additionally, having to consider the length, height, and weight of your boat. Furthermore, it is often recommended to have two anchors of different designs, especially for a larger craft. In simple terms, an anchor can be the difference between your boat staying in place or drifting onto the rocks or shoals. As such, it is important to choose the right type.

With that said, what are the best types of sailboat anchors for a sailboat?

Table of Contents

As the name implies, it is shaped like a plow and is commonly used as a primary anchor for larger powerboats and cruising sailboats. The main advantage of a Plow anchor is versatility, as it can dig into softer bottoms such as grass, sand, and mud. In addition, it resets easily should the wind or current change direction.

However, like all anchors, a Plow Anchor has a few downsides. Most notably, it struggles in rocky bottoms, which can be said for most types. Another consideration is storage, as a Plow anchor is heavier and takes up more space due to the hinged design.

A modern variation of the Plow anchor is the Spade anchor . While similar in appearance, it has a sharper pointed edge for digging into the bottom. As a result, a Spade has more holding power, enabling a boater to use a lighter anchor. As for drawbacks, like a Plow, it fares poorly on rocky bottoms and takes up more space due to the longer fluke and roll bar. In addition, being a new design, Spade sailboat anchors are still patented and more expensive than some of the other options.

The Fluke anchor , or Danforth, is frequently used as a primary anchor on smaller boats and sailboats due to its lightweight, excellent holding power, and compact size. However, it can be used as a stern or secondary anchor for larger craft. While a Fluke anchor is regarded as the best type in the mud and sand, it is less than ideal on other surfaces. In addition, it tends to become unstuck if the wind or currents shift and the boat drifts in the opposite direction that the sailboat anchors are set.

Claw sailboat anchors are popular for boaters thanks to their all-around performance. It is easy to set, grips well in sand and mud, and can hold on to rocks and coral. As for disadvantages, Claw anchors can have difficulty digging into clay and grassy bottoms. Like the types mentioned above, it is bulky and best suited for a bow install.

What Style of Sailboat Anchors Are Best?

As you can tell, there is not a “one-size-fits-all” anchor as there are several factors to consider, such as the bottom, size, and windage of your boat. Likewise, for larger craft, one or two anchors, and what type? Lastly, what material, galvanized steel, stainless steel, or aluminum, although the latter is more popular with sail boaters due to its lightweight.

12 Best Sailboat Anchors for Any Sailor

Having the ability to anchor out inside a nice peaceful bay or right outside of a marina avoiding all the hubbub can be an amazing feeling.

It’s an even better feeling knowing that your sailboat is securely fastened using the best sailboat anchor so that you don’t start floating away when the tide or wind starts to shift.

There are a lot of amazing anchors out there that are potentially a great fit for you and your sailboat as a primary anchor.

Having a clear understanding of what makes a good, high-quality sailboat anchor from a trusted brand means you’ll be able to make a more educated choice when deciding which anchor is best for you and your sailboat.

The Best Sailboat Anchors

Depending on your style of sailing and the whereabouts you like to explore, you may need one sailboat anchor over another.

Based on my experience, there are a lot of great options out there to choose from, which is why I put together the following list of the best sailboat anchors.

1. Rocna Vulcan Galvanized Anchor

One of the best sailboat anchors out there today based on being the best-selling anchor for yachts and workboats goes to the Rocna Vulcan Galvanized Anchor .

As one of the pioneering brands for sailboat anchors, the Rocna Vulcan was able to transform from the original Rocna anchor to the most dependable, best anchor out there today.

The Rocna Vulcan is actually a modified version of the original Rocna anchor, which was one of the most groundbreaking anchors to have been engineered and set the stage for the Rocna Vulcan.

The original Rocna anchor was designed in New Zealand back in 2004 and took the industry by storm. By taking the best features from more traditional anchor types, like the Bugel anchor and Spade anchor, it was able to set itself apart.

The Rocna Vulcan has a lot of fantastic features to it apart from being a very strong and powerful anchor. For one, it has the ability to dig into almost any type of seabed, which comes in handy when sailing in diverse locations.

It’s also relatively lightweight and easy to stow due to it not having a roll bar like its older brother, the original Rocna.

Another great feature is that it has no moving parts, so no one’s fingers have the chance of getting pinched.

When it comes to the construction material of the anchor, the Rocna Vulcan is a galvanized steel boat anchor, which means it’s very strong, long-lasting, and relatively inexpensive.

The design of this sailboat anchor allows for it to self-right itself when landing on the seabed and when being pushed around by currents and tides. It also comes with a lifetime warranty, so it’s guaranteed to last the lifetime of your sailboat.

All in all, the Rocna Vulcan is a great choice for any sailboat looking to anchor out.

Regardless of where you are, it’s highly likely you’ll be able to use your Rocna Vulcan to anchor and feel good that you have a popular, well-designed anchor manufactured by a trusted brand.

If you’re serious about getting one of the best boat anchors, definitely check it out.

2. Manson Galvanized Supreme Anchor

As one of the most famous boat anchors that were released when the original Rocna anchor came out is the Manson Galvanized Supreme Anchor .

As a matter of fact, this anchor came out in 2003 and is well known to this day as being extremely effective due to having a very high holding power, an effective roll bar, and an ability to settle to the seabed quickly.

You certainly cannot go wrong with a Manson Supreme anchor if you decide to get one. They have very high holding power, are able to dig into almost any seabed, have no moving parts, and are able to touch the seabed quickly.

While their major advantages are definitely the holding power and fast settling, this comes at the price of being rather heavy which can make stowing this anchor difficult at times.

3. Lewmar Galvanized Delta Anchor

Even though there are a number of modern anchor types that have taken the industry by storm, some of the more traditional designs still hold their weight to this day.

That’s why the Lewmar Galvanized Delta Anchor  is still on the anchor scene, especially since it’s been a hallmark anchor for a very long time.

There are a number of good reasons to go with this anchor by Lewmar especially the fact that it has a strong holding power in softer seabeds (like mud and sand).

It’s also relatively lighter than other sailboat anchors allowing for easy stowing and transportation. Another great quality is that it’s all one piece, so there’s no potential issue of pinched fingers.

The only downsides include that it sometimes requires a tripping anchor line to release it from the seabed and that it’s not ideal for hard seabeds or seabeds covered in kelp.

4. Spade Anchor S120 Galvanized Steel

Another well-known, traditional design for anchors is the Spade Anchor S120 Galvanized Steel .

This type of anchor has been around for quite some time and has proven itself as a worthy contender to even the newer, more modern anchor types.

It certainly set the stage for a lot of anchor designs today and it continues to shine even today.

The Spade anchor is a very popular style of anchor that was designed in France back in 1996.

It was based on the delta style anchor design in a way to achieve a similar grip power to the seabed but by providing an even large surface area contact to the seabed.

This sailboat anchor is lightweight and can dig into soft seabeds quite well making it a great fisherman anchor for most fishing boats.

One of the downsides is that it sometimes Spade anchors needs the assistance of a tripping line to remove it from the seabed.

5. Lewmar CQR Anchor

Of all the more traditional anchors out there today, one of the most famous that really shook the anchor industry is the Lewmar CQR Anchor .

Before the more modern sailboat anchors, the CQR anchor (or the plow style anchor generally) was the go-to anchor for many yachts and workboats.

If you’re looking for a classic, time-tested anchor, the CQR might be the anchor for you.

The CQR anchor was designed in the UK way back in 1933 and has been one of the most well-known anchors out there. It was known to be so secure (and it still is), that it was named CQR because it sounded like “secure”.

This anchor’s relatively lightweight, digs into the seabed quite well, and is rather versatile in terms of the texture of the seabed it can grip.

However, it does have some downsides including it being oddly shaped so stowing is more difficult, it has moving parts, and it sometimes requires a tripping anchor line to remove it from the seabed.

6. Lewmar Claw Anchor

Another great anchor that’s been around for a while is the Lewmar Claw Anchor , which has been known as either the Bruce or Claw anchor in the past.

The strong reputation of Claw anchors has been well-known in the anchor industry for a long time and is further proven due to being manufactured by the trusted brand Lewmar.

The Lewmar Claw anchor is a fantastic anchor to own due to it being relatively lightweight, strong, and inexpensive.

As a matter of fact, it’s one of the best sailboat anchors anyone can buy since it has a lot of positive advantages like it has no moving parts and it’s easy to remove from the seabed.

The only downsides include it having an odd shape, making it a bit more difficult to stow, and not being the best when penetrating seaweed or grass-like seabeds.

7. Danforth S-600 Standard Anchor

There’s no doubt that even some of the traditional anchors still have a place in the best anchor category and that goes double for the Danforth S-600 Standard Anchor .

Similar to the CQR anchor, this anchor has been around for quite some time and was developed in the US back in the 1940s.

As a matter of fact, they were originally manufactured to be equipped with certain landing aircraft during WW2.

The Danforth anchor is an industry standard and has been a hallmark for many decades. They’ve been used as anchors for many types of vessels and are especially good for anchoring out in loose seabeds like sand or mud.

It’s also relatively lightweight and can be stowed easily since it’s pretty flat. Unfortunately, it has some moving parts to it, sometimes requires a tripping line to get it out of the seabed, and is certainly not ideal for more rocky seabeds.

8. Norestar Stainless Steel Danforth-Style Anchor

While the original Danforth anchor is a great choice for your next anchor, a step up in terms of quality is the Norestar Stainless Steel Danforth-Style Anchor .

While you’ll certainly spend a bit more money for this Danforth-style anchor, the design improvements ensure a safer anchoring and a longer-lasting product.

This Danforth-style anchor by Norestar provides all of the advantages of owning a traditional Danforth with some extras.

First, it has no movable parts so there’s no chance of pinching fingers while operating the anchor.

Second, it allows for anchoring off in seabeds that are rockier than the original Danforth can handle. It even comes in stainless steel, which means this anchor will last a very long time.

It does, however, still have the downside of at times needing a tripping line to release it from the seabed.

9. Norestar Stainless Steel Bruce Anchor

The Bruce anchor (also known as the Claw anchor) is a popular style of anchor that’s been used for a very long time.

There’s no question the Norestar Stainless Steel Bruce Anchor is a step up in the design of this anchor style, similar to how they improved the Danforth.

This Bruce/Claw anchor is a great choice for your sailboat’s next anchor since it has a good holding power for almost any seabed texture.

It’s also quite lightweight, has no moving parts, and it’s very easy to break it from the seabed.

Even better, it’s made out of stainless steel, so it’s built to last. Honestly, there aren’t too many downsides to this anchor apart from it being relatively expensive.

10. Norestar Stainless Steel Delta Anchor

The Norestar brand is amazing at taking the more traditional style of anchors and improving its designs to make them more attractive.

Well, they’ve done that once again with the Norestar Stainless Steel Delta Anchor .

The Delta anchor was already an improvement to the CQR anchor, but Norestar decided to take it to the next level.

The Delta anchor by Norestar is one of the highest quality stainless steel, delta-style anchors you could put on your sailboat.

Apart from it being stainless steel like the rest of Norestar’s anchors, it’s also lightweight, has no moving parts, and has a powerful holding power in softer seabeds.

However, it might not be the best sailboat anchor on seabeds with hard sand and it might require a tripping line to set it free from the seabed.

11. Mantus Galvanized Anchor

Some of the best sailboat anchors are originally derived from the more traditional sailboat anchors (in particular those with a roll bar), which is definitely the case for the Mantus Galvanized Anchor .

As one of the most well-known anchor types out there, this anchor manufactured by Mantus Marine stands out as a top contender for the best sailboat anchor.

This anchor by Mantus is produced with galvanized steel which makes it quite strong, inexpensive, and dependable.

With its uniquely designed roll bar, this sailboat anchor is able to properly land on the seabed when making its descent resulting in getting a better grip of wherever it ends up.

This anchor is specifically designed to break through dense grassy bottoms, so definitely a consideration when buying your next sailboat anchor.

12. Fortress Anchor

Sometimes it’s important to break free from the most well-known anchor brands and see what else is out there.

After stepping outside and digging into other anchor styles, I fell upon the Fortress Anchor , which is an aluminum fluke anchor that has a lot of common characteristics found in the traditional Danforth-style sailboat anchor.

The Fortress anchor has a very similar design to the Danforth but differs in the sense that it’s even more lightweight since it’s made out of aluminum magnesium alloy.

Some of the clear advantages that make this a candidate for the best sailboat anchor are that it settles quickly to the bottom of the seabed, it can be disassembled for easy storage, and it’s been tested to have double the holding power compared to its competition.

Downsides include movable parts, sometimes requiring a tripping line to remove it from the seabed, and not being ideal for rocky seabeds.

What to Consider Before Buying a Sailboat Anchor

We went over a good amount of high-quality sailboat anchors just now, so you should have a good idea of what anchor you might consider purchasing for your sailboat.

However, there are a few considerations to take into account before making that purchase, which is what we’ll cover now.

Construction Materials

You’ll find a number of different construction materials for anchors, like aluminum and steel, but by far the most common materials you’ll find is a metal anchor made of steel or aluminum alloy.

Galvanized Steel

Anchors made out of galvanized steel are often found to be less expensive and shiny compared to other types of anchor materials.

The great part is that they’re very strong and can last a very long time. Unfortunately, they’re prone to corrosion so it’s not uncommon to have to get them re-galvanized.

Stainless Steel

Anchors made out of stainless steel are very strong and aesthetically pleasing in terms of their appearance since it’s rather shiny.

You can’t go wrong with getting a stainless steel anchor, but you’ll definitely be forking over more money to get one.

Aluminum Alloy

Anchors made out of aluminum alloy are very lightweight compared to steel but often come at a much higher cost when going through the checkout line. However, when set correctly on the seabed, they’re known to have very high holding power.

Lakes vs. Coastal Waterways

Depending on where you’re sailing, you’ll need a certain level of strength to keep your sailboat from moving around while anchored.

Sailing in coastal waterways definitely requires a strong anchor than when sailing around lakes, so it’s generally advised to stick with the stronger anchors just in case.

If you know your sailboat will never leave the lake scene, go with a weaker (and thus cheaper) anchor.

Anchor Weight to Boat Length

You might’ve been wondering how strong your anchor should be based on the size of your sailboat.

Well, there’s no hard and fast rule to the exact strength (or weight) your anchor should have, but it’s definitely possible to determine a minimum weight to cover some worst-case scenarios when using your anchor.

A simple way to determine the minimum anchor weight of your sailboat is to subtract 5-10 lbs from every foot of your sailboat’s length overall (LOA). For example, if your sailboat is 40 feet long, then a 35 lb boat anchor would be a good weight.

This is a good rule of thumb when choosing an anchor weight for your sailboat, but should only be considered as an estimate and for minimum weight.

If the anchor you plan to purchase has a chart helping you decide on the proper weight to get, you should definitely follow that.

Anchoring & Mooring

With so much investment literally riding on your anchor, your boat's anchoring system is no place to cut corners. your choice of anchor depends on the size and type of your boat, and the weather and anchoring conditions you generally encounter..

Boats with heavy displacements or superstructures that present a great deal of wind resistance need heavier gear. The same is true of cruising yachts that brave a wide variety of conditions and may sometimes have to anchor in open waters.

Although not required by Federal Law, it is recommended you carry one anchor of sufficient size and strength to hold your boat for an extended period, like overnight--or in an emergency situation, such as if you run out of gas. When you are thinking or buying an anchor - BIGGER IS BETTER.

Also, there is safety in numbers. No anchor will work for you in every situation, so if you have space carry two anchors--preferably of different types.Many people choose to carry a small anchor, or "lunch hook", and a larger working or storm anchor. The lunch hook is for use in calm weather and when the crew is monitoring the anchor. Working and storm anchors are useful at times when the crew is asleep or ashore, and during heavy weather, when winds are 30 miles an hour and over.

The general name for all of the equipment you need to anchor your boat is "ground tackle". This includes an anchor, chain, line and connecting elements. The anchor line, including chain, is called the rode.

Playing Hooky

Just as boats come in a wide variety of shapes and sizes, so do anchors. Choosing an anchor is easy, choosing the right one for your boat can be very difficult. Your first task in choosing an anchor is to have an understanding of three things:

• Your Boat - Your boats' size, weight and design characteristics affect what kind of anchor you will need to use. For instance, a 30 foot 10,000 pound houseboat needs a larger anchor than a 30 foot 6000 pound speedboat.
• Where You're Going - Where you plan to anchor often dictates what type of anchor you should use. Is the bottom rock, or is it soft mud? If you are not familiar with the area, ask around or look at a local chart.
• Local Conditions - Anchoring in a calm protected cove can be quite different than anchoring offshore or on a large open bay. And don't forget the weather--high winds, tides and waves can all make anchoring difficult, if not impossible.

Anchors are rated by "holding power"--which is the ability of an anchor to hold a given weight. Keep in mind that a 10,000 pound boat may only require an anchor with a holding power of a few hundred pounds on a calm day, but may need 1,000 pounds of holding power or more on a stormy day.

Anchor Types

There are several types of anchors and you should choose a style based on the bottom characteristics in the areas you will anchor most often. Then, choose a size based on the size and weight of your boat.

Lightweight or "Danforth" Anchors

Lightweight type anchor with two long pivoting "flukes"; designed to reduce clogging with mud and grass; range from 2.5 pounds to nearly 200 pounds, and are generally made of cast galvanized metal, though some models are machined from a light-weight aluminum composite. When dropped, flukes dig the anchor into the bottom and the anchor buries itself and part of the anchor line.

Commonly used on small recreational boats, as they are relatively light weight for the amount of holding power they provide, especially in comparison to other anchors. Best in hard sand or mud, where flukes can easily dig into the bottom.

Not recommended for very soft or loose mud, which can ball up around the flukes; or on rocky bottoms where the flukes cannot penetrate. Also not recommended for grassy bottoms, which the flukes tend to slip off.

Kedge or Navy Anchors

A more traditional style anchor with arks, flukes and stock. Good in heavy grass, weeds, rocky bottoms or hard sand where one arm can penetrate a crevice. Not good in mud or loose sand, where flukes can't dig in.

Functions differently than previous anchors as it is not a burying anchor; one arm digs into bottom and one lies exposed. Generally only used by very large ships, as it relies on weight for most of the holding power; not really suitable for recreational use other than for a lunch hook.

Grapnels Anchors

Very inexpensive, but not much holding power. Some models are made of bent re-bar, others are made of galvanized metal and have folding flukes. Good for recovering items on the bottom, or for wreck reef anchoring. Commonly used on very small boats such as canoes or jon boats.

Plow or "CQR/DELTA" Anchors

The plow styles' good holding power over a wide variety of bottom types makes it a top choice of cruising boaters. Has either a fixed (Delta style) or a pivoting (CQR) shank.

When dropped in the water, a plow lands on its side, then when pulled, buries itself. Its shape allows it to reset fairly easily should the wind or tide shift the boat position.

Great in sand and on rocky bottoms, weeds and grass. Does not do well in soft bottoms. Generally made of galvanized metal, though they are available in stainless steel.

Claw or "BRUCE" Anchors

Unique shape of the claw allows a 360 degree turn without breaking out. Has similar performance to plow anchors,at a lower weight.

Sets just like a plow, but curved flukes make it easier for a claw to right itself no matter how it lands on the bottom, or how much the boat gets swung around.

Mushroom Anchors

Mushroom anchors get their name from, as you might imagine, their rounded, mushroom shape. Mushroom anchors are used extensively for moorings, and can weigh several thousand pounds for this use.

The shape works best in soft bottoms, where it can create a suction that can be difficult to break. Decent for very small boats to use as a lunch hook, but not practical for larger boats. Both Buoys and Beacons may have lights attached, and may have a sound making device such as a gong, bell or horn. Both Buoys and Beacons may be called "marks".

Line and Gear

Depending upon the size and type of your boat, and where you anchor--your choices for an anchor line are either an all-rope anchor rode, a combination of rope and chain, or all chain.

Nylon Line in Three-Strand Twist

Three-strand line can absorb shock and the constant tugging associated with anchoring much better than braided line or chain alone. Chain may also be used, especially in anchorages that are primarily rock or coral, which may cut a nylon line. A length of chain should be used between the anchor and a longer length of line. The chain will add weight to set your anchor without making it too heavy to lift manually, while serving to exert a horizontal pull on the anchor to set it.

Nylon Three-Strand line is the leading choice for use as an anchoring line. Lines generally come in a "soft" or "medium" lie. Soft lines are generally softer to the touch, and loosely woven. These aren't as good as medium or hard lines for anchoring, as they are more prone to unraveling and chafing. Tightly wrapped lines are the best choice for anchoring.

Lines that have been treated with a wax-like coating are available. These lines help the line resist water/salt absorption. To help keep your lines in good shape, clean them from time to time by soaking them in soapy water. Never use bleach, as it can break down the line.

Chain may be used instead of nylon line for anchoring. Chain has several benefits, including added weight, chafe and wear resistance, and high strength. It also lowers the angle of pull on the anchor, which helps it to set more firn\mly into the bottom.

Chain is generally found made of galvanized steel, though you can find stainless steel and vinyl coated chain, which is designed to be non-marring to your deck.

Chain comes in three general varieties: "Proof Coil" is the most common, and is adequate for most marine uses. "BBB" ("Triple B" or "3B") chain has thicker, shorter links than proof chain. BBB is slightly stronger than proof chain, and is generally used for windlasses. Finally, "Hi-Test" chain is made of hardened steel, and is stronger and lighter than proof coil. Hi-test chain is favored by those wishing to avoid carrying too much weight.

Combination anchor-rodes consist of both chain and nylon line. You may buy a combination rode, or you may make one yourself. Generally, it is recommended to have either one foot of chain for each foot of boat length, or to have one pound of chain for each pound of anchor length. Which ever method you choose, having more chain than necessary is never a bad idea.

As the saying goes, a chain is only as strong as its' weakest link...Make sure that your anchor and line are attached to each other with adequate gear. Some lines come with plastic thimbles or eyes--but metal, either marine-grade stainless steel or hot-dipped galvanized steel, is best. Swivels and shackles should be inspected regularly for wear, and to ensure that the connections are tight and functional.

Scope: Length of the anchor line/ height of the deck cleat to the sea bed.

Before leaving the dock, you will need to determine how much anchor line, or "rode", you will need. It is recommended that you use a scope of 7:1, meaning that for every foot of water depth, you should use 7 feet of rode.

For example, to anchor in 10 feet of water, you would pay out 70 feet of line. Measure the scope as the ratio of the length of the anchor rode to the height of the bow above the bottom. If you're using a lightweight anchor on a small boat in good weather conditions, a shorter scope of 5:1 is sufficient and safe. A prudent boater always has extra line and chain on hand, just in case.

Minimum Working Rode Sizes

Suggested holding sizes assume fair holding ground, scope of at least 5:1 to 10:1, and moderate shelter from high seas.

Boats that operate generally in shallow waters, as on the East Coast of the United States, may get by with shorter rode lengths. As the wind picks up, deploying additional line will help maintain position, as will tossing out an extra anchor.

Setting Anchor

Anchoring can be accomplished quickly and easily by following a few simple steps.

• Check your chart for bottom characteristics and to determine that you are anchoring in a safe and allowable place. If there are rocks, shoals, reefs or other boats to consider, give them all as wide a berth as possible. Remember that other boats will often have different requirements for anchor rode length--larger or taller boats frequently need a great deal of rode. Also, keep in mind a possible swing of 360 degrees about the anchor with wind shifts or current changes.
• If your crew is not already wearing PFDs, have them put one on before going forward to set or retrieve an anchor or mooring.
• Secure the bitter end of the anchor line to a bow cleat. Make sure the line is ready to run free once tossed overboard.
• Head into the wind or current. Reduce speed and reverse the engine. When the boat starts to make a slight sternway through the water, lower - do not throw - the anchor.
• After you've let about a third of your line out, tug the anchor line to see how firmly it's set, and then continue to release the rode.
• Once you let out an appropriate amount of scope, make sure the line is properly tied off on the bow cleat.
• Even if anchoring only in designated anchoring areas, it is always prudent to have the appropriate signal such as an all-around white light on to notify other boats that you are anchored at night. During the day you must display a ball shape which is sized according to the size of your boat.

Staying Put

It's a good idea to take two immediate bearings. Select two items, one off each beam, that form a natural range and watch for any changes in their relationship. You can check these later to determine if you're boat is swinging as expected or if you're dragging anchor.

Picking Up a Mooring

One of the best ways to avoid the hassles of anchoring is to chose a cove or harbor with moorings available for your use. Mooring balls are identified by their white spherical or can shape, and having a blue horizontal band. It may have a number designation, a VHF contact # or name on it. You will typically have to pay a small fee to the harbor master to use a public mooring, but you can count on it being far cheaper than paying for dockage for the night.

Public moorings are professionally maintained and will use a large anchor or helix screw fixture to maintain position. The harbor master will let you know if the weight or length of your boat is too big for that particular mooring. Although moorings are typically more secure than anchors, moorings can and do periodically give way. For this reason, and for the obvious courtesy reasons, you should never pick up and use a mooring that does not belong to you.

Common Anchoring Mistakes

• Letting the anchor go with out securing the line to the boat.
• Letting the anchor go with your foot wrapped in the anchor line.
• Poor communication between the captain and person on the foredeck.
• Approach a mooring from downwind. This will give you better maneuverability as you go to secure your boat to the ball.
• Go slow, so as not to disturb those already moored.
• After putting on PFDs, send a crew member to the bow with a boat hook to grab the eye or the base of the mooring ball.
• Once the mooring ball is at the bow--slow, stop or gently reverse engines to halt forward motion. Use your crew to relay distance information if it is difficult for the skipper to see where the mooring ball is in relation to the boat.
• Loop the mooring line over one or both of your bow cleats. Pay attention to the possibility of chafing. You may want to use your own line to attach to the mooring ball if the one provided is dirty.
• Some moorings may have an antenna like device called 'whip.' This is simply an extension of the ball so you don't have to reach as far to haul in the mooring line.
• Once secure, let the boat drift back and be sure that you are clear of those who have moored or anchored around you. There is no need to 'back down' on a mooring ball.
• Leaving a mooring is easy--just motor or pull up gently to the ball and release the mooring line from your boat. You can then either drift back or maneuver forward to clear yourself of the ball and the associated ground tackle.

Finally, never ever anchor a small boat by the stern! Your engine, and the bulk of the boat's weight rest here. Stern anchoring is likely to result in swamping and flooding.

Best anchors: 8 new generation designs suitable for every boat

• Rupert Holmes
• January 27, 2022

Most boats would benefit from upgrading to a better anchor for a host of reasons. We take a look at 8 of the best anchors on the market right now

Securing your anchor do it is ready to drop could get you out of a tight spot when you can't sail out of trouble. Credit: Theo Stocker

Good ground tackle and understanding how to anchor properly opens up the option to stay overnight in stunning bays and creeks, away from costly marinas and expensive harbour moorings. And picking the best anchors is essential in terms of safety too as you may well need it to hold you off a lee shore in the event of engine failure.

However, unless your boat’s anchor has been upgraded recently, the chances are it’s of a type that will not provide good holding power.

What to look for in a good anchor?

Much has changed in the world of anchors in the past 20 years, which led to classification societies such as Lloyds adding a new Super High Holding Power certification category for these anchors in 2008.

Most of the best anchors exceed the requirements for this by a wide margin.

These advances in anchor technology and different types of anchor mean older boats won’t have been equipped with what we would now consider to be decent ground tackle when they were new.

This is also true for most vessels built in the last 20 years. Until recently the latest generation of anchors was relatively expensive, so were generally only fitted as standard equipment to very high quality yachts.

The various brands of today’s very high holding power anchors share a number of key characteristics that make them more effective than older products.

The best anchors tend to have a concave profile akin to the shape of a shovel. This digs more firmly into the seabed without tending to act like a plough when under load.

Another important aspect to look for in a good anchor is the tip weight, as loading as much weight here as possible is a massive help in enabling it to penetrate weed and other difficult types of sea bed.

Typical new generation anchors have 35-45 per cent of their weight on the tip. Some also have roll bars that prevent the anchor landing on the seabed upside down.

Whatever anchor you choose, beware of cheap unbranded copies. These rarely have the precise geometry needed to maximise holding power. Some are also badly cast and therefore weaker than the original design.

Rocna Galvanised Anchor

This was one of the first of the new generation of ultra high holding power anchors and quickly gained much acclaim, despite an initially high price tag.

The Rocna is well engineered and has an excellent reputation for digging in quickly and easily. Once set it then offers excellent holding.

A roll bar is incorporated, but a downside of Rocnas is they do not stow neatly on all bow rollers.

To solve this problem the company developed the Vulcan series, which doesn’t have the roll bar and is shaped to fit on a wider range of bow rollers.

Reasons to buy:

– Good quality anchor

– Excellent holding power

Reasons to avoid:

– It is expensive

– Do not stow neatly on all bow rollers

Specifications:

– Size: 96 x 41 x 39 cm

– Weight: Available in 10kg, 20kg and 25kg

Lewmar Stainless Steel Epsilon Anchor

Read PBO’s Lewmar Epsilon review

The latest model from this UK company offers the benefits of a new generation anchor at very attractive prices.

It has a winged design with concave flukes to maximise holding power in a variety of sea beds, a ballasted tip that enables it to dig in readily and is self righting, even though the roll bar is optional.

The Epsilon is intended as a direct replacement for Lewmar’s long-running plough style Delta anchor.

Although the Epsilon’s shank is proportionately shorter, the two models share the same basic shank geometry. Therefore, if a Delta fits your bow roller then an Epsilon will also fit.

– Easy to handle

– Designed to fit any bow roller that works for the Delta

– It has a shorter shank

– Size: ‎55 x 35 x 30cm

– Material: stainless steel

– Weight: ‎6.1kg

Fortress FX-11

This aluminium anchor is an older design from more than 30 years ago, but still has a number of advantages that makes it an excellent choice in some circumstances.

It’s biggest feature is very light weight relative to the holding power the anchor provides. This makes it a perfect option for performance catamarans and trimarans, as well as for smaller fast motor boats.

The key downside, however, is that the holding power is achieved through the surface area of the flukes, not the weight of the anchor. This means it’s physically larger than other anchors, although it comes apart like the Spade for easier stowage.

A neat feature is that the angle of the flukes can be varied to suit different types of sea bed.

– Perfect for catamarans and trimarans

– Easy to manoeuvre thanks to its light weight design

– Flukes can be adapted to the type of sea bed

– Larger than other anchors

– Holding power is from the surface area of flukes

– Size: ‎73.66 x 15.24 x 7.62 cm

– Material: aluminium

– Weight: 8 pounds

Spade Anchor S series

This is another popular modern anchor, but with an important difference to other brands.

The hollow shank can be removed to make stowage easier. This makes it an excellent choice for racing yachts and other vessels that don’t permanently keep the anchor on the bow, or for occasional use as a kedge.

There’s no roll bar, but the tip loading is close to 50 per cent of the total weight, which helps it to dig in and set quickly.

The main drawback of the Spade is one of cost – it’s more complex to manufacture than other designs, so the price is relatively high.

– Good option for racing yachts

– The hollow shank can be removed

– No roll bar

– Expensive

– Size: S40 to S160

– Material: galvanised steel

– Weight: 6kg to 55kg

Knox Anchors

Professor John Knox spent a great deal of his spare time researching the loads on anchors and rodes.

His work in this area over a period of 20 years contributed a huge amount to our understanding of anchoring and precise causes of anchors dragging or breaking out.

It also led him to develop his own design of anchor that would offer significantly better performance compared to the popular models at the time. It was therefore one of the first of the new generation designs.

The Knox anchor has a patented divided fluke with sharpened edges set at an angle that enables it to dig into the seabed quickly and efficiently.

It’s fitted with a roll bar and, while the shank is made of the highest tensile strength steel available.

– Made of the highest tensile strength steel

– Patented divided fluke with sharpened edges set at an angle to dig into the seabed

– We can’t find any

– Material: highest tensile strength steel

– Weight: 6.5kg to 27kg

Stirrup Anchor Bugel Anchor

The Bügel was one of the very first new generation anchors and quickly set a new benchmark in the industry.

It has a flat fluke with lower surface area than later designs, plus a roll bar and a shank made of thick plate.

This makes it a relatively inexpensive anchor, which is undoubtedly a key factor behind its enormous popularity, even though later products offer higher holding power.

– Good value anchor

– It features a rollbar and shank

– Other products offer higher holding power

– Size: 66 x 28cm to 86 x 38cm

– Material: Hot-galvanised steel

– Weight: 9 to 16kg

Buy it now from compass24.com

Manson Supreme Anchor

This was the first anchor to receive Lloyds Super High Holding Power certification when the classification was introduced in 2008.

It’s a fabricated design that uses two layers of steel for the fluke and relies on a roll bar, rather than a ballasted tip, to self-right.

The upper slot in the shank is intended for use in rocky sea beds, or anchoring in coral . The idea is that if the anchor becomes stuck the rode can be slid to the shank end of the slot, enabling the anchor to be retrieved without using a tripping line.

The shape of the anchor is designed to fit all conventional anchor rollers.

– Good for use on a rocky sea bed

– The anchor fits all conventional anchor rollers

– Other products offer innovative designs compared to this classical anchor design

– Size: 18′ – 30′ to 40′ – 45′

– Weight: 7kg to 20kg

Ultra Marine Ultra Anchor

Read Yachting Monthly’s Ultra Anchor review

Our sister title Yachting Monthly recently tested the new 12kg Ultra Anchor from Ultra Marine over several nights at anchor.

Editor Theo Stocker said: “I was impressed with how quickly the anchor set.

“While our normal 10kg Bruce anchor can struggle in soft sand and weed, the Ultra anchor buried itself almost completely and refused to drag.

“The Ultra’s performance amply delivers on its maker’s promises as is comparable to other stainless anchors,” he concluded.

– Handmade and hand-polished stainless steel

– Ready to dig in

– Not the cheapest option on this list

– Weight: 5kg to 8kg

How to Anchor a Sailboat

Last Updated by

Daniel Wade

June 15, 2022

One of the most vital skills for a sailor is oftentimes one of the most confounding ones. Setting the hook in all the different types of anchorages you’re likely to end up in can be confusing to new boaters. Despite how perplexing it can be, this skill is incredibly important, lest you find yourself waking in the middle of the night to the sound of your boat dragging anchor towards rocks.

Good technique and properly-sized equipment for anchoring is vital. Yet, more times than not, even experienced sailors are distracted or in a hurry and skip one of the vital steps for anchoring securely. Even worse, some new sailors never learn the essentials and just throw any anchor-shaped hunk of metal overboard, hoping for the best. That tactic isn’t likely to keep you safe while you slumber so let’s go through what you should do instead.

Table of contents

A Little Forethought

The first thing to do when you’re going to anchor is to pick an anchorage. This may already seem like a lot, but picking a good spot is crucial. You must understand the conditions of that spot before tossing your anchor into the water and calling it good.

Use the chart you purchased or printed out, making a note of all the vital information. Things like wind direction and speed, tidal currents, and even the forecast can be important pieces of the puzzle. Pay extra attention to anything that might reverse the direction your boat is being pulled to prevent having your anchor pulled out.

The best spot is going to have some protection from the wind and waves. You would prefer to have a sand or mud bottom as opposed to a rock or heavy grass bottom. If you have a brand new chart, it’s probably going to have information on the bottom characteristics as well as some of those good spots marked out. You should also make sure that your spot is a few feet deeper than the draft of your boat during low tide.

Once you’ve picked your spot, it’s time to prepare the anchor. Whether lowered by hand or on a roller, make sure the anchor rode is free to run. If it isn’t marked at progressive depths with tags or color codes, stretch it back and forth on deck to keep track of how much rode you’re letting out. For safety’s sake, plan out at least 6 times the water depth.

Actual Anchoring

The actual technique of anchoring can be a bit tricky to learn but can buy you some peace of mind once mastered. Knowing your boat isn’t going to slip off into the night or ram into a neighbor because your anchor dragged can be a massive relief. No one wants to awaken to a bump in the night.

First, you have to actually position the boat where you want to anchor. For motorsailers, you may find this easier to do under power. However you decide to do it, move slowly. There is no need to rush this. It’s better to take a long time on a secure anchor than to rush and drag later. Once you’re over the position, drop anchor. Be careful not to drop a ton of chain on top of your anchor.

Once the anchor is on the seabed, let the boat drift back gradually as you pay out chain. Don’t disturb the anchor yet. For the anchor to work, you want to pull horizontally along the seabed. You are setting the scope as you pay out the chain. The goal is to get the anchor to pull at 15° to 20°. Once sufficient chain has been let out, secure the anchor chain on deck.

Now we have to wait for the anchor to dig in and take its initial set. Once you have the initial set, begin slowly moving astern until the anchor chain straightens out. While you’re moving your boat, pay very careful attention to the chain. If it jumps, that means you’re dragging anchor. If everything seems alright then feel free to hook up the snubber and let out more chain until there’s a loop of it between the snubber hook and the bow roller. Congratulations on anchoring your boat.

Additional Tips

Some additional tips and tricks are in order. This is just good information to have in the back of your mind when anchoring.

Using the Right Type of Anchor

First, your type of anchor heavily influences your ability to set the hook.  Most cruising sailboats are going to be equipped with at least two types, each with their own separate rodes. The preferred choice for the bower is generally a spade while a lightweight Danforth generally takes the spot as a kedge. Be familiar with the anchors you’re going to be using and how they’re designed to function.

It may seem strange but the good old-fashioned fisherman’s anchor isn’t going to work the same way as a modern CQR anchor. They are also going to do generally better at different sea beds.

Find the Right Size

Match the anchor you’re using to the size of your boat. All anchors are not created equal. If you’re using a 15lb anchor on a 33ft motorsailer, you are probably not going to have it easy. If you don’t appropriately size your anchor for your vessel, you are increasing the chance of dragging.

If you aren’t sure what size anchor to get, check with the boat’s manufacturer. They often have recommendations. At the end of the day, it’s alright to go on the bigger side of things. Don’t choose your anchor for reasonable conditions. Expect the absolute worst situations because you can’t change your anchor when you’re already out on the seas.

Dragging the Anchor

Understand what it really means to drop anchor. This isn’t a literal phrase. You should lower the anchor slowly. Lowering the anchor gradually prevents the chain from falling on the anchor flukes and fouling the anchor. Dropping it too quickly makes it more likely that a fouled anchor is going to drag if the wind comes up later.

Even when you’ve anchored perfectly and everything has gone according to plan, you should still check periodically.  Changing conditions could result in that perfectly-set anchor deciding to drag anyway. Before you take a load off for the night, make sure to have a few ways to tell if your boat is dragging. A modern method is a GPS which can easily reveal a change of positions.

Something a little lower tech would be a small secondary anchor with a noise maker tied to it and dangled over the cockpit. If set up correctly, when the boat moves, the secondary anchor’s rope will pull and cause the noise maker to fall down into the cockpit. If all goes as planned, you wake up to the banging and take any actions needed.

A way to verify dragging is to check the anchor rode at the bow. You may be able to see or feel changes in its tension. If the anchor is bouncing all over the place, it will be easy to spot or feel.

Anchors Aweigh

Keeping your boat from dragging and drifting into rocks, another boat, or a reef is at the top of your priority list. In order to make sure your anchor sets properly and your night of sleep isn’t interrupted by the sound of a boat running aground, it’s best to be safe rather than sorry.

Go through your plan slowly. Make sure you pick the best anchorage for your needs. Check that none of the conditions might change while you’re on the hook, causing your boat to drift in the opposite direction and pull your anchor free. Ensure that you have the right equipment to begin with and make sure to double-check the anchor before you call it a night. It’s better to stay up a little later and make sure your anchor is properly set than to wake up to bad news.

How to Pick a Boat Anchor: The Guide to Types, Sizes & Weights

October 20, 2023

Lakes can get choppy, and river currents can drag you along when you'd rather stay put. Having the right anchor on your boat is crucial, especially if you're busy staging for a wakeboard or ski ride .

But what type and size of anchor is best for your setup?

Types of Boat Anchors

Let's look at the most popular types of boat anchors, and look at some charts to figure out what size and weight anchor is right for you.

Fluke Anchors

Also known as a Danforth anchor, the fluke anchor is favored by lake and river boat owners for its lightweight design and excellent holding power in soft bottoms.

Fluke anchors have a rotating bar that connects the anchor to the line. Their forward-heavy profile allows the flukes to drive straight down into sand or mud. As line is laid out, the bar swivels into a horizontal position, providing good scope.

• Boat Size: 30 feet or less
• Best For: Lakes, rivers, mud and sand
• Bad For: Rocks, debris, coral, strong currents

Plow Anchors

Also called a delta anchor, the plow anchor is one of the most popular anchors on the boat market. It's simple and effective, capable of providing reliable mooring in all water conditions and most beds.

Plow anchors dig into the surface below and they provide high holding power. They set quickly, which makes them an excellent choice when strong currents and winds could otherwise quickly move your boat.

But plow anchors' large, flat fins can get stuck in debris and large rocks, so it's best to stick to softer bottoms.

• Boat Size: 70 feet or less
• Best For: Sand, mud, grass bottoms, strong winds
• Bad For: Rocky bottoms

Claw Anchors

Also known as a Bruce anchor, the claw anchor is similar to a plow anchor: It sets quickly and digs into soft bottoms, providing good holding power against currents and wind -- though not as well as a plow.

Because claw anchors use smaller pins, they're better suited in gravel and rock, affording a lower risk of catching and getting stuck where a plow anchor might get hung up.

Digger Anchors

The digger anchor excels at providing high holding power in gravel and rocky bottoms, even with strong currents and high wind. It uses a rod that partially rotates, while limiting the angle of the anchor line's scope.

As current and wind pull on the boat, the rod's limited angle pulls on the anchor's claws, pushing them further into the bottom. The digger's thin, long claws work great in virtually all bottom, including gravel and small rocks -- just avoid large debris, as the limited angle of the anchor rod prevents it from being pulled back out of a snag effectively.

• Boat Size: 40 feet or less
• Best For: Sand, mud, grass, gravel, strong winds
• Bad For: Bottoms with large debris

Navy Anchors

The classic, heavy, big navy anchor excels at providing high holding power in all waters and conditions. Its size and shape make it suitable for rocky bottoms and debris fields, as it has little risk of getting snagged.

The only problem with a navy anchor is that its benefits can become problematic for smaller vessels: Because navy anchors are large and heavy, they can be difficult to stow, and they add plenty of weight to the hull.

• Boat Size: 20+ feet
• Best For: All bottoms, currents, and weather
• Bad For: Small, light boats

Mushroom Anchors

The mushroom anchor is made for small vessels in relatively calm waters with soft bottoms. It relies on suction and sinking into sand, dirt, and mud to provide holding power. These anchors are typically found on light, electric motor-powered boats, kayaks, and dingy boats.

• Boat Size: 12 feet or less
• Best For: Soft bottoms free of rock
• Bad For: Large boats, heavy currents, rocky bottoms

River Anchors

Like the mushroom anchor, the river anchor is also intended for small vessels in lakes and rivers -- but with one exception: The river anchor works well in rocky bottoms and beds filled with debris. The wide, flat flukes work best when they can grab hold of objects on the floor. River anchors work well enough in soft bottoms, albeit with less holding power than a mushroom.

• Best For: rocky bottoms and debris fields
• Bad For: Large boats, heavy currents

Choosing The right Size Anchor

When selecting a boat anchor, it's important to consider the following factors:

The size and weight of your boat will determine the size and weight of the anchor you need. As a general rule, the heavier the boat, the larger and heavier the anchor should be.

Water and Weather

The type of weather and currents you encounter will influence your anchor choice. Different anchors perform better in different conditions, so it's important to choose one that suits your boating environment.

Conditions of Water Bed

The floor your anchor rests upon can vary wildly. Some lakes and rivers have rocky bottoms filled with debris, while others have soft silt or sand. Picking the wrong setup could mean you wind up drifting, or worse, cutting line because your anchor got stuck at the bottom.

Anchor Weight vs. Boat Size Chart

The chart above is a general guideline for selecting the appropriate anchor weight for your boat. Conditions on the water, and the weight of your boat -- regardless of its size -- could mean you need a heavier anchor.

Anchor Chain vs. Rope

When it comes to anchoring, you'd think chain is far superior to rope. But chain really only provides two advantages: It adds holding power, helping to keep your boat moored in one spot in rough water and strong currents, and it resists chafing -- it won't suffer damage from being dragged along debris and rocks.

Chain is heavy, though, so it adds weight to your craft when not being used. This isn't a concern on large, sea-going vessels. But you probably don't want that added weight when you're cruising around on the river or lake, especially when towing a wakeboard, tube, or skis.

Chain also rusts, even with regular maintenance, and it's expensive. Nowadays, synthetic anchor rope is tough and abrasion-resistant, and it withstands water and sunlight incredibly well. It's also lightweight relative to its strength, and it takes up much less space than chain.

The most effective setup combines a bit of chain near the anchor, with rope making up the rest of the line. Just a few feet of chain is needed to ensure your anchor is properly seated. This bit of chain also improves the scope of your line. "Scope?" You, say? Read on.

It's All About Scope

Rope alone will provide as much holding power as chain, so long as your scope is correct. Scope measures the ratio of the length of deployed rope (or chain) to the height from the ocean, lake, or riverbed to the anchor point on the boat.

The minimum effective scope you need to properly moor your vessel with any anchor and line is 5:1. That means if the depth from your boat's topside to the underwater floor is 5 feet, you need 25 feet of rope laid out below. This affords about 75% of the maximum holding power of your anchor and line.

A scope of 10:1, laid perfectly flat on the bed below, provides 100% holding power. Using the same 5 foot depth, you'd need 50 feet of anchor rope or chain laid out for max holding power.

Best Types of Sailboat Anchors

When buying a sailboat anchor, you want to ensure the safety of your sailboat, when mooring or setting anchor at the middle of a bay. There are many types of sailboat anchors available in the market and not all of them are constructed of same materials. This article will analyze different types of boat anchors, how to choose the best anchor for your boat, as well as the different types of their construction materials. The right anchor means not just the right design for the type of seabed you’re anchoring on, but also the appropriate size for your sailboat.

Here Are The Most Common Types of Sailboat Anchors

The spade anchor – best sailboat anchor overall.

A new generation anchor, it comes in a welded one-part or two-part design that can be easily disassembled with a spanner. Also, this sailboat anchor has excellent holding power. It provides balance and always arrives on the seabed point down, something that enables it to set very quickly. This Rocna Vulcan Galvanized Anchor has amazing holding power and, talking from experience, will never disappoint at any seabed or weather condition. It is also becoming a favorite for people who liveaboard and are looking for strong dependable anchors to have on their sailboat. I couldn’t recommend this anchor more.

Danforth or Fluke

The Danforth, or Fluke anchor, is a very popular anchor. It performs well in sand and mud, possibly the best among many anchors styles. The disadvantage is that outside of these bottoms, it is not a good performer. Thus, it is a sand anchor, which is what most bottoms are comprised of. However, it is the best anchor style in terms of weight to strength or anchoring ratio. Furthermore, it’s easy to store because it lies flat. The angle of the flukes is standard for 32 degrees or up to 45 degrees for soft mud. All these are Danforth boat anchors . You just need to find the right size for your boat.

Delta & Plow, Wing, or CQR

This type of anchors is bulkier than Danforth anchors. Both Delta and CQR are a plow style anchor. The difference between these anchors is that the Delta is a one-piece design, while CQR is a hinged design. Moreover, the delta and plow anchors are easy to store at the bow of your sailboat rather than in a locker. Delta and CQR demonstrate good performance in most bottoms, but they struggle in rock. This Lewmar Delta is a great sailing anchor that you can pick up from Amazon at a great price.

Bruce or Claw

The Bruce or Claw anchor rights itself and plows into the bottom, primarily because of its design. The Bruce is an all-purpose anchor because it performs well in most sea bottoms. These could be sand, mud, and rock. Its three-claw design sets more easily than other anchors. However, the Bruce anchor has an average holding power, which means that you might need a larger anchor, i.e. the Delta or Wing. Take a look at all these Bruce anchors available online and pick one that is the right size for your boat.

Fisherman, Kedge, or Herreshoff

It’s probably the best of all, in terms of holding in thick kelp or rock, but also more specialized. They are the traditional anchor shape that we all know. Modern kedge-style anchors are lighter and can adapt to specialized use. Furthermore, their sharp bills and small flukes hold better in hard sand. Kedge anchors are often used in heavy vegetation seabeds . However, I wouldn’t recommend this type of anchor to have on your sailboat since there are better and more versatile ones out there.

This type of anchor is similar to other plow anchor styles. The difference is that it has an adjustable fluke angle. Adjustable angles mean that they can be adjusted for different bottom conditions, unlike the Plow and Delta anchors. Although Super Max is a bulky anchor, it’s really effective.

Mushroom and River Anchor

These anchors are suitable for permanent mooring buoys. This style is designed to gradually dig itself deeper and once inserted, it has great holding ability. On the downside, this anchor does not work well in weedy or rocky bottoms. It is mostly useful in temporary anchoring situations. Although this type of anchor can be handy on your boat or sailboat it shouldn’t be the only one or even the second anchor aboard.

The Bugel Anchor

Another new generation of sailboat anchors, and also the first to sport the rollover bar. Furthermore, it has a simple design that makes it affordable. The Bugel Anchor provides excellent performance in most seabed conditions. However, they were widely replaced by spade anchors and you can’t really find them in most marine stores or online.

Best Material Types For Sailboat Anchors

There is a wide variety of anchors constructing materials. The most common are mild steel, stainless steel, high-tensile steel, and aluminum. Most of the traditional anchors we know are either made of mild or high-tensile steel. The difference between them is that high-tensile steel is 2 or 3 times stronger than mild steel. Keep in mind that these anchors are not corrosion-resistant, thus they have to be galvanized in order to prevent rust. In general, steel anchors (except stainless) should be galvanized. Most sailors choose a galvanized anchor because they are affordable, but also because they have the highest tensile strength. Nowadays, some anchors are made of aluminum and rely on their shape for their function.

Connection Between Sailboats and Anchor Size

So, what’s the minimum size of sailboat anchor for a vessel of a particular length? For example, a 20ft sailboat will need an anchor of 15lb. Then, a 30ft sailboat will need an anchor of 25lb. Finally, a 36ft sailboat will need an anchor that weighs 35lb. Generally, anchors work in two ways. They can be massive and use their weight to keep the boat from drifting, or lightweight and bury themselves in the bottom, in order to stop the boat from moving. Of course, a combination of both is optimal and as a general rule, you want a bigger anchor that you think you need. That way, even if you find yourself in heavier weather than expected, you want one less thing to worry about.

What Characteristics Make a Good Anchor?

Firstly, it must dig in fast every time. Secondly, it has to bury deep, because of the greater the mass of seabed above and ahead of the anchor, the better the holding power. Thirdly, it must have excellent holding power. Finally, it must hold in the different wind conditions. For instance, when the wind shifts, the anchors have to drag around in order to face the new direction. Prefer the anchors that remain buried while dragging, rather than capsizing and pulling out. Moreover, the static holding power can’t be more than 20 times the anchor’s weight. For example, if you use a 15kg anchor, its static hold will be approximately 300kgf. In a 40 knot wind and for a 33ft yacht, this is probably the force that the anchor will receive.

Summary – What is the Best Sailboat Anchor?

In general, all of the above-mentioned anchors meet the four basic performance criteria. However, some of them demonstrate better performance in terms of holding power in certain types of seabed. For example, the Danforth is quite good in any sand, but there’s still a risk of it rolling and pulling out as the currents turn. On the other hand, Fisherman performs excellently in rock or kelp. However, nowadays the design of the new generation anchors provides much better-holding power and are generally more reliable in their movement.

Everything You Need to Know About 8 Major Boat Anchor Types

There are quite a few types of anchors you can use for your boat and they are not all interchangeable so it’s key that you pick the right one. Many boaters carry more than one type as not all anchors work well in all conditions. It’s good to have an anchor that can work on soft, muddy surfaces as well as one that can work in hard or rocky conditions. If you know where you’ll be boating and what conditions are like ahead of time, you can prepare by ensuring you have the right anchor. 

All an anchor needs to do to be functional is hold your vessel in place in the water. But this requires an anchor suited to both the size of your boat and the conditions below the surface of the water.

Let’s take a look at 8 of the most common anchor types to see what they’re good for and how they work.

Fluke Anchor or Danforth Anchor

Fluke is the type of anchor, but Danforth is a trademark name. It’s like tissue versus Kleenex. The name “fluke” is a reference to the pointed parts of the anchor that stick out like teeth.

• Description: Some fluke designs can come apart, and some are solid. Typically, they are made of lightweight aluminum and offer remarkable strength and holding power even when they are rather small and light.  There are several fluke designs, and some may have multiple flukes, but there will be at least two present.  These are great for bass boats, pontoons , and much more.
• Boat Type : Small to medium boats under 30 feet
• Ideal For : Muddy, sandy, and soft seabeds
• Bad For: Rocky bottoms, hard bottoms, coral
• Advantages: The flukes can dig in like a scoop and bury themselves deep, allowing the pressure of the mud/sand and water to push down on the flat parts of the flukes, creating a strong hold to keep your boat in place. This is arguably the best kind of anchor to use in these situations
• Disadvantages: If the ground is packed hard or covered in rocks or weeds, the fluke will be less effective at getting any grip and may not be able to lock into anything at all, making it essentially useless. 
• Cost: Fluke anchors run a range of prices based on size and quality. Some smaller flukes that still perform very well can be purchased for under $25. Higher quality and larger flukes can be found for $100 to $150. 

Claw Anchor or Bruce Anchor

Bruce is the trademark name for a kind of claw anchor.

• Description: Claw anchors resemble plow anchors but with a broader scoop section and typically three teeth or claws that it uses to dig into the substrate to gain hold. 
• Boat Type: Mid-sized boats up to about 60 feet
• Ideal For : Soft bottoms that are muddy but also rock and coral
• Bad For: Loose seabeds like sand are not ideal for the claw, and hard clay bottoms will offer no purchase. Claws do not perform well in weeds, either.
• Advantages: Claw anchors are considered some of the easiest to use. Setting a claw anchor is usually quick and easier than other anchor types. It’s also easy to reset when it comes loose, so many boaters prefer it and consider it a good, all-around anchor for most conditions. It works best when the bottom is soft so it can get some purchase, and it also does well in rock and coral because the teeth or claws can wedge into place.
• Disadvantages: Pound for pound, the claw anchor also has less holding strength than most other anchors so in poor conditions, you may find a claw anchor coming loose on its own far more than you’d like. 
• Cost: The smallest Bruce or claw-style anchors start around $30 to $40 and are best suited for smaller vessels. Larger and heavier claws, especially stainless steel ones, will increase in price to as much as $150 or more. Marine-grade claw anchors that weigh over 40 lbs can even break $500.

Mushroom Anchor

These are more often used for permanent moorings, like for buoys, as their holding power only increases over time as silt and debris builds up on top of it. They work by simply sitting in place and allowing the cup part to fill up over time as the current deposits material inside.

• Description: Mushroom anchors get their name from their shape, which resembles an upside-down mushroom cap.
• Boat Type : Tiny boats or permanent moorings
• Ideal For: Sandy or loose bottoms so the sediment can collect in the mushroom.
• Bad For: Large boats as well as rocky or hard bottoms
• Advantages : Mushrooms are some of the cheapest anchors and they come in small sizes that are ideal for very small boats. Larger mushrooms can hold things in place permanently if they are given time to really take root.
• Disadvantages: Most mushrooms are not ideal for temporary mooring because they need time to become buried and provide resistance. They have very limited holding power for larger vessels, especially for short term anchoring. On a bottom that is hard or rocky, a mushroom anchor will not be able to provide any holding power as they need soft material and silt to fill in the cup and provide resistance. 
• Cost: A cheap, cast iron mushroom anchor made for a small vessel might cost you around $20. Heavier mushrooms, up to 20lbs, that have a vinyl or galvanized coating can cost as much as $70 or more.

Grapnel Anchor Or Grappler Anchor

They are designed to work on a rocky bottom where the hooks can wedge in between and around rocks to form a strong hold.

• Description: These anchors resemble a grappling hook and tend to have four or more hook-like fingers spread out around the central column. The claws usually fold down when not in use, making this one of the most space-saving anchor designs.
• Boat Type: Smaller vessels under 15 feet
• Ideal For: Rocks
• Bad For: Soft or muddy bottoms
• Advantages: Grapnel anchors are best for smaller boats like canoes because of their compact size and holding power. Once set, it’s very hard to release a grapnel anchor so the hold is reliable.
• Disadvantages: These anchors don’t work well without rocks to hold onto. They also tend to come loose easily if the winds and currents change which doesn’t make them ideal for any sort of long term anchorage.
• Cost: Grapnel anchors can be incredibly cheap with dinghy-sized anchors at under $15. Larger galvanized or stainless steel versions can range from about $60 to $90.

Plow Anchor or CQR Anchor

CQR is a trademark name for a kind of plow anchor. These get their name because they look like an old-timey plow you might find in a field. These anchors are very old and, as such, are very common as well.

• Description: Where a fluke has two or more teeth, a plow has that center fluke or tooth that will dig into the bottom to give the anchor the needed hold.
• Boat Type: Medium-sized boats around 60 feet
• Ideal For: Soft bottoms like sand or mud and also weeds
• Bad For: Hard or rocky bottoms, also very loose bottoms
• Advantages: A plow anchor is one of the best anchors for handling changes in wind and current. They are less likely to break free and need to be reset in these conditions. They tend to work well in many conditions and are fairly reliable and predictable as a result.
• Disadvantages: Plow anchors don’t offer as strong a hold as many other anchor types, and, as a result, to get one that works, you may need to opt for a heavier anchor than you would if you used a different type.
• Cost: Galvanized steel plow anchors can be just over $100, while stainless steel plows can get up around $250 or more.

Delta Anchor

This is another kind of plow anchor and sometimes it’s called a wing anchor. Delta anchors are some of the most popular anchors in use today and are solid, all purpose anchors. These are ideal for most sized vessels including larger boats.

• Description: Delta is a single-piece anchor while the CQR is a hinged piece, so the operation is slightly different. Otherwise, this is much the same as a typical plow anchor.
• Boat Type: Up to 70 feet
• Ideal For: Soft, muddy bottoms but also sand and clay.
• Bad For: Rocks
• Advantages: The Delta anchor is reliable in many conditions and, When it does grab hold because it’s one solid piece, it offers a surprisingly strong hold as well, especially when compared to similar anchors.
• Disadvantages: May be too large or expensive for many boats.
• Cost: A Delta anchor for a boat around 30 to 40 feet may set you back $400 to $500. A 22lb stainless steel Delta can be over $700. That said, you can find many Deltas for smaller boats that cost between $100 and $200.

Box anchors are a relatively new anchor design but have proven to also be extremely versatile. They are not designed for any specific size of boat and seem to work well with all kinds. They say you can even anchor a houseboat with box anchors.

• Description: They are designed in a box shape lined with hooks or flukes along the outside edges. It works in any bottom condition by digging into harder surfaces or scraping softer ones to fill the box and add weight. Because of how this anchor sets, you may need less anchor line to use it.
• Boat Type: Potentially any boat, though it may be overkill for smaller vessels.
• Ideal For: Any seabed
• Bad For: May be unnecessary for smaller vessels
• Advantages: The box anchor uses less line than a traditional anchor and can hold a 45-degree angle. The down-facing flukes can dig into the seabed without catching on debris, and the anchor can also reset itself when it comes loose. The box anchor can set almost immediately after dropping it. It offers some extreme holding power with less anchor rode than many other modern anchors, making it one of the more popular up-and-coming anchor styles.
• Disadvantages : Because they’re so new, they are not as well tested or trusted yet, and they can also get a little pricey, especially for casual boaters or those with smaller vessels. 
• Cost : You can get box anchors from about $100 for a basic version up to around $300 for a stainless steel one.

Shallow Water Anchor or Power Pole

Power pole anchors work automatically by using what looks like a hydraulic arm to raise and lower the pole and root it in place. A DIY shallow water anchor can be as simple as a fiberglass pole attached to the hull with a clamp. 

• Description: Unlike a standard anchor attached to a line and dropped overboard, a shallow water anchor is essentially just a pole extending from the side of the hull down to the surface below the water. Because it’s for use in shallow water, it anchors the boat directly to the ground below without requiring a line.
• Boat Type: These anchors are often used on jon boats , flats boats , or any vessel used for fishing in very shallow water.
• Ideal For: Shallow water
• Bad For: Deep water, larger rocks.
• Advantages: With a power pole set up, these anchors can be set into nearly any kind of bottom and then released again in just moments. They also offer an extremely secure hold that roots the boat in place to ensure minimal movement while fishing. DIY poles are often cheap and easy to make, and many video tutorials are online.
• Disadvantages: A Power Pole type boat anchor can be a major investment, and not every boater wants to put that much money into an anchor. By the same token, a DIY version will be cheaper but may take some time and effort to produce, and also you may need to do some trial and error to get it to work.
• Cost: Power Poles can cost over $2000 and also require maintenance. A DIY pole, however, can cost you $20 or $30 depending on the design.

The Bottom Line

There are a number of types of anchors which work with whatever sized boat you have and whatever surface you are trying to anchor in. It’s always important to test your anchor out to make sure it meets your needs, can hold your boat, and is easy for you to both set and release when needed. 

Most anchors don’t cost a lot of money but some larger or more complex designs can set you back a considerable sum of money so make sure you’re investing in something you truly need before committing to any purchase. 

My grandfather first took me fishing when I was too young to actually hold up a rod on my own. As an avid camper, hiker, and nature enthusiast I'm always looking for a new adventure.

Types of Anchors: How to Choose the Right Size Anchor

Most new boats do not come equipped with an anchor, but every boat should have one on board. You may want to drop the anchor to hold the boat in a secluded cove for an afternoon of relaxation or even an overnight stay , or just to hold your boat over fishing structure.

The anchor is most important as a critical item of safety gear . If you should lose power, it’s the anchor that’s going to keep your boat from drifting into peril, be it rocks or another shoal, or the dangers of a surf-swept shoreline. The best anchor first depends on the size and type of your boat.

A tall sportfishing boat or power cruiser that can catch a lot of wind will need heavier gear, for example, then a low-profile bass boat . Boats used for long-distance cruising may need to anchor in rough weather, and on a variety of bottoms, and thus will need not only heavier gear but also several different anchors suitable for different bottom conditions.

How to Anchor a Boat: Step-by-Step Guide

Consult a Boat Anchor Size Chart

Anchor manufacturer guidance, usually based on boat length, can be a good starting point to determine which size anchor is appropriate for your boat. If your boat is heavier than typical boats of that length, or presents more windage, you should select a larger anchor.

The same logic applies if you frequent an area with high winds. Generally, the bigger the anchor, the better, but the anchor’s holding power in the bottom, rather than its weight, is what really matters. Always keep your ground tackle (the anchor and its rode, or line) ready to deploy at a moment’s notice.

Types of Boat Anchors 

Once you have a better idea of what size anchor you need for your boat, you'll also want to consider the type of anchor. Let's explore some of the most popular options available for boaters when it comes to anchors.

Mushroom Anchor

Very large mushroom anchors are used for moorings or securing buoys. Small mushroom anchors may be effective in the softest river bottom but have minimal holding power. They should be used only for personal watercrafts , small aluminum fishing boats , or dinghies .

Danforth or Fluke Anchor

This style of anchor is a good choice for smaller boats because it folds flat and is easy to stow, and has great holding power for its weight. Its wide, sharp flukes sink into sand and hard-mud bottoms, but are less effective in deep mud or a grassy bottom. If the wind shifts and boat drifts over the anchor and then in the opposite direction from which it was set, a Danforth anchor can pull free.

Plow Anchor

A plow anchor is a little more cumbersome than a Danforth, and is a good choice if the anchor is secured on a bow roller rather than in an anchor locker in the boat. A plow anchor has a single penetrating point and is more likely to reset itself if boat position changes. It can be more effective than the Danforth in light grass, has the strength to hold in a rocky bottom if it gets a good grip, and does well in soft bottoms.

Claw Anchor

This non-folding anchor is similar to the plow anchor, but has a broader scoop shape that works well in mud, clay or sandy bottoms. These anchors are also strong enough to hold on a rocky bottom. A claw anchor will re-set quickly if the wind changes. It may not work well on a very hard bottom, or in thick vegetation, both challenging for all types of anchors. This anchor is also best-suited to installation with a bow roller or windlass .

Grapnel Anchor

Shaped like a grappling hook, this anchor has multiple tines or points, and is designed to grab onto structure on the bottom—such as rocks or submerged timber—rather than sink into the bottom. The tines usually fold up along the shank so that the anchor is more compact for stowage. On some models the tines are designed to bend to make it easier to retrieve the anchor if it becomes snagged on bottom structure. The tines can them be bent back into shape. Grapnel anchors are available in many sizes, including very small models for jon boats , skiffs or small boats , like kayaks.

5 Boat Anchor Types Explained (With Pictures)

I myself lost an anchor while out on the lake. It had been an accident, but we were prepared. I was so incredibly thankful we had a spare!

This article will break down the different types of anchors, their uses, and which will work best for your specific needs!

Table of Contents

1) Fluke Anchors

Let’s start with the basics!

The most common anchor used is the Fluke anchor. It is also referred to as a Danforth anchor or a Lightweight anchor.

Fluke anchors have high holding abilities attributed to their wide and flat flukes, commonly made from strong steel.

The Fluke anchors can firmly keep your boat in place. When the flukes at the end of the anchor dig themselves into the bottom with a sand bed, it uses the slight pulling forces of the boat itself to keep it in place.

This anchor type is often the anchor type used for smaller boats. As the name suggests, it is lightweight and easy to handle.

This anchor also stows flat, making it incredibly easy to store. This is important for smaller boats that may not come with high amounts of storage space.

Storage of your anchor, when not in use, is recommended. This is true for all anchor types. They are often sharp and painful when accidentally kicked or stepped on. They can also slide around if not stored properly, which could cause injury or loss of the anchor.

This is often the “go-to” anchor because you can use a lighter anchor for your boat than the weight you would need for other anchor types.

Choosing the proper Fluke anchor is dependent on the length of your particular boat. Fluke anchor weight can range from 4 pounds to 44 pounds or more.

Recommended Weight of FLUKE Anchors per Boat Length:

Some of the boat lengths that are listed above can be compatible with more than one size.

If your boat is on the heavier side or planning to anchor in more aggressive water, you will want to consider using a heavier option.

2) Plow Anchors

Another prevalent anchor type is the Plow anchor. You can tell it is a plow anchor because it will look like a large shovel or scoop.  The original maker of these anchors called them a CQR. A more modern option is called a wing anchor, like the Delta.

The Plow anchor has strong holding power in more types of bottom conditions than the Fluke anchor.

This anchor is also used on larger boats. They are more forgiving when the wind changes direction so that they re-set more easily.

This anchor can be more difficult to store than the Fluke anchor, but special chocks are available to mount them deck.  They also often fit well on bowsprit anchor rollers.  This is why some people purchase both a plow anchor and a Fluke anchor to meet the particular anchoring conditions.

Plow anchors gradually plow themselves into the bottom, burying themselves to create hold.

This anchor is designed to swivel so that change in pull does not cause it to lift out of the ground. This issue can be a problem for the Fluke anchor since it is not designed to swivel this way.

Like the Fluke anchor, choosing the proper Plow anchor depends on the length of the boat. The Plow anchor typically ranges between 26 and 60 pounds. This makes them heavier than the Fluke anchor, making them more difficult to operate but gives them more holding power.

Recommended Weight of PLOW Anchors per Boat Length:

3) grapnel anchors.

The grapnel anchor can be either fixed or folding.  It does not have the ability to hinge or swivel. Like the Plow anchor, they use their weight to set and hold.

This anchor holds similarly sized boats as the Plow anchor but is usually used on smaller boats.  Its major disadvantage is that the upright flukes can tangle with the anchor line and pull the anchor out.

Like the Plow anchor, this anchor holds up in more bottom types than the Fluke anchor.  It does not usually hold as well as a Plow anchor, though.

Like the Plow anchor, the grapnel anchor is heavy to handle and difficult to store, unless it is the folding style.

Unlike the Plow anchor, the grapnel type anchor has some lighter options, making it a better choice for smaller boats.

The grapnel anchor type can range in weight from 13 to 66 pounds.

Recommended Weight of Grapnel Anchors Per Boat Length:

Like the Fluke anchor, if you have a heavier boat for its length or expect volatile conditions, opt for the heavier option.

4) Claw Anchor

The Claw anchor is also a popular choice because it sets easily and deals well with most types of bottoms. This includes rock, which the previous anchor types mentioned are not ideal for.

The Claw anchor has a wide three-claw design that was originally known as a Bruce anchor.

The Claw anchor, however, can be more difficult to set and hold well.  This means you may need a heavier anchor for your vessel than you would with the other options above.

Like the Plow and grapnel anchor, this anchor is heavy and awkward to stow.  But like the Plow anchor, it will often fit well on a bowsprit anchor roller.

The Claw anchor is relatively less expensive than other anchors, so it remains a popular choice among recreational boat owners.

The Claw anchor can range in weight from 6 pounds to huge industrial sizes. This is the widest range offered by all the options.

Recommended Weight of CLAW Anchors per Boat Length:

Because of the anchor’s range of holding power, quite a few options above overlap. You will want to make sure you opt for the heavier option to ensure your boat holds.

5) Scoop Anchors

The scoop anchor is the term for a number of the new generation of modern anchor designs.

The first of these designs was the Rocna, and now includes others such as Spade and Manson.  These designs are getting very popular because they work in many types of bottoms and have high holding power.

The scoop anchors have been tested thoroughly, and they will generally set and reset easier than the other options.  Because they set so well, you can often use a lighter weight.

However, the scoop anchor can be more difficult to manage and store on the deck or in a locker.

The early versions did not fit well on a bowsprit anchor roller because they had roll bars to help them set and re-set better.  Newer versions have resolved this issue.

The scoop anchor can range in weight from 6 pounds to huge industrial sizes, also.

Recommended Weight of Scoop Anchors per Boat Length:

Because the anchor’s holding power will depend on the boat’s weight and windage, it is used on quite a few options above overlap. If your boat is heavy for its length, you will want to make sure you opt for the heavier option to ensure your boat holds.

3 Factors To Choosing The Right Anchor Type

With a large variety of options, you are probably thinking: so, which one do I choose?

Most boaters agree that you should have two different styles of anchors. This will allow you to use one based on where you are and what you need.

This also allows you to set multiple anchors if needed. This can help with crowded areas or extreme weather. Setting an anchor off the front and back of your vessel can reduce your swinging range when that is important.

There are 3 factors to look at when picking the right anchor for you.

One major factor to look at is the bottom of the body of water you plan to boat in.

1) Consider The Bottom Type For Where You Are Going

This is one of the most important reasons to bring more than one anchor, especially if you are not familiar with the body of water or its bottom.

Bottom Types include:

• Sand : easy for setting and has a high hold.
• Mud : requires a deeper and wider setting for a stronghold.
• Rock/Coral : setting depends more on where you drop your anchor than what anchor you drop.
• Shale/Clay/Grasses : relies on the weight of the anchor more than its design.

Recommended Anchors For Each Bottom Type:

2) Choose The Right Anchor Size (Weight)

After you determine what type of anchor you need for where you are going, you will want to make sure you apply the size charts listed under each anchor.

This is to make sure you pick the proper weight for your particular boat.

When in doubt with any anchor I mentioned above, opt for the heavier option. This will provide more stability and security, no matter what conditions you might encounter.

Some boaters like to have one lighter anchor (a “lunch hook”) for calm conditions and a more robust anchor for overnight anchoring.

The final thing to consider is what your anchor should be made from.

3) How To Choose The Right Anchor Material

There are three common materials your anchor could be made from.

These include galvanized steel, stainless steel, and aluminum.

Some pros and cons of each metal type are as follows:

*If your galvanization begins to wear down, you can always get it re-galvanized.

Final thoughts

There are many other important considerations with anchoring correctly and confidently.

These include the size (diameter) of the line or ride; and the length of the rode for the water depth, called scope.  For instance, an all-chain rode will hold better than a short length of chain and rope.

This is another whole topic, though.

Hopefully, by using this guide, you can pick the anchor that is best for you and your boat.

The proper anchor can help you be confident while you are out on the water and gives you one less thing to worry about!

COMPARISON TABLE – THE BEST SAILBOAT ANCHORS

8 things to consider to find the best sailboat anchor, monohull vs. multihull vessel types.

A beginner sailor might question which anchor is better for their vessel’s hull type. But to be clear–when it comes to choosing an anchor for either monohulls or multihulls (like catamarans), the type of anchor you choose depends more on your vessel’s size and weight. Vessel types are rarely–if ever–a deciding factor.

LAKES VS. COASTAL WATERWAYS

Lakes and rivers do not require the same strength you would need for coastal waters and open seas. But take your sailboat on the Great Lakes, ICW (Intracoastal Waterway) or to brave a transatlantic journey, and you’ll need something more adequate. All anchors listed here are for coastal waterways, but may also be efficient for smaller bodies of water.

CHOOSING THE CORRECT ANCHOR WEIGHT FOR VESSEL LENGTH

To choose the correct anchor weight for your vessel, you need to know your vessel’s weight and length. Always verify the anchor manufacturer’s specifications and suggested vessel length, but know the numbers are typically inflated. I suggest to always bump up to the next size and sail with a heavier anchor than your vessel requires.

CONSTRUCTION MATERIALS

Anchors are forged from a variety of materials; some metals more modern than others. Keep in mind when you purchase that manufacturers may carry anchor styles in a variety of materials.

Aluminum anchors are lightweight by comparison, but come at a cost. Less affordable than steel anchors, they are also not as strong. But sailor prefer them because–when set correctly–they have high holding power.

GALVANIZED STEEL

Galvanized steel is a very strong and inexpensive metal. This material is perfect for sailors who don’t much care how shiny their anchor appears on the bow roller. But although galvanized metal is corrosive, it can wear over some time. Be sure to look for hot-dipped galvanized steel or plan for it to be re-galvanized.

STAINLESS STEEL

If you want your anchor to appear more aesthetically pleasing, stainless steel is the material of choice. Stainless steel is also more resistant to rust and corrosion, but keep in mind it scratches easily and can make anchors more costly.

HIGH TENSILE STEEL

With nearly 3 times the holding power strength as regular steel, making most anchors with high-tensile steel relatively stronger–as long as the anchor sets well.

MANGANESE STEEL

A newer material offered for anchors is manganese steel. Manganese combines the strength of mild steels with high-impact durability for setting repeatedly in rocky seabeds.

SEABED CONDITIONS

Beneath the water’s surface, you can encounter a variety of seabeds. This is one of the most important deciding factors in choosing a sailboat anchor. For liveaboards who find themselves sailing in a variety of seabeds, a plow style anchor or scoop is universal, whereas fluke anchors are perfect for flat sands and muddy bottoms.

ROCKS, REEFS AND CORAL

Rocky seabeds can secure anchors quite well, if not a little too well. Sometimes, sailors find themselves needing to dislodge anchors which become stuck. In these cases, it’s wise to use anchors with slotted shanks, making it easier to release trip lines.

MUD, SAND AND GRASS

Muddy bottoms and sandy seabeds require fluke-style anchors with wide surface areas. And because mud can disguise underlying sediments, it also helps if the anchor can penetrate. Fortress anchors are great for these seabed conditions.

Sandy seabeds grab anchors very well, but challenges arise during shifting tides. Hinged-shank fluke anchors allow pivoting and non-hinged scoop anchors rotate under the sand.

Grass tends to be slippery, making it difficult for certain anchor types to grasp. In these seabeds, heavier anchors outperform engineered designs.

WEATHER CONDITIONS

Even if you have a nightwatch partner, sudden storms overtake vessels and send them off course. If you want to set anchor without the worry, many new generation anchors have been tested in hurricanes and outperformed old guard anchors in extreme weather.

HOW WELL DOES IT SET?

If an anchor lacks a way to position itself, it may not set as optimally as intended. You want to assure the anchor is engineered to self-right itself into position when it falls on the seabed. Anchors can set by using a combination of factors from roll bars to tip ballasts to chiseled fluke styles.

The new generation anchors are designed with roll bars, reacting to flat seabeds by self-righting and rolling itself over. Originally engineered by Rocna , the design has been further adopted by more anchor manufacturers like Manson .

TIP BALLASTS

In place of roll bars, tip ballasts are simply weighted on one end. It will naturally tilt toward the tip ballasts edge, allowing the anchor to set when it’s dragged. Anchors can have both roll bars and tip ballasts.

DOES IT MOVE WITH CURRENT & TIDE CHANGES?

One challenging skill in dropping anchor is, in fact, getting it out again to reset. With some anchors, setting it on the first try is a matter of luck, especially when you’re unsure of your seabed condition. It’s important to be able to quickly reset, or you may find yourself strapping on a wet suit and goggles to retrieve it in frigid waters.

Sailors should always carry two anchor varieties. This way, after reading a sonar signatures to determine your depth and seabed conditions, you can choose which anchor will best hold as well as the scope needed to reach.

HINGED SHANKS

Hinged shank anchors are needed for sailing in waters where there are tidal changes. If the sailboat turns about, a hinged shank can pivot itself without having to be reset. But moving parts pinch so watch those fingers!

FIXED SHANKS

Fixed shank anchors are fine anchors if you aren’t worried about tidal changes and currents. You may also rely on fixed shanks in muddy seabeds if they are also scoop-styles.
