The Importance of Good Anchoring Technique

Few sailing experiences are as scary as waking in the middle of the night with the wind blowing hard and your boat dragging anchor toward rocks, the shore, or another boat. And one of the most irritating things for most cruising sailors is finding another boat dragging down upon them or getting tangled in their own anchor line.

Good anchoring technique is crucial for safety. Yet all too often even some experienced sailors are in too much of a hurry and skip one of the important steps for anchoring securely. Some new sailors never learn the essentials and just toss the anchor overboard and assume they’ll be fine.

But it is not difficult to anchor correctly and securely in most conditions. Follow these guidelines to help ensure your boat is safely anchored so you can get a good night’s sleep.

1. Prepare in Advance

• Pick your anchorage carefully using an updated chart and paying attention to conditions, including wind direction and speed, likely tidal or other currents, and the forecast. Pay special attention to the chances for a shift in wind direction or speed. If your boat is pulled in the opposite direction during the night because of a reversing tidal current or wind, the anchor may be pulled out.
• The ideal anchorage area should have some protection from the wind and waves and not be against a lee shore in case the anchor drags. The ideal bottom is sand or mud, not rock or heavy seaweed or grass. Most cruising guides and some charts show good anchorages that are protected and have good holding ground. Charts also show bottom characteristics when known.
• Get the anchor ready before making your approach. Whether on a bow roller or lowered by hand from the bow, make sure the anchor rode is free to run. If the anchor rode is not marked at progressive depths with tags or color codes, stretch it out back and forth on deck so that you know how much rode you are letting out when anchoring. To be safe, plan to put out a rode about 7 times the water depth (counting the height of your bow over the water) at high tide.

2. Pick Your Spot Carefully

• After studying the chart and choosing a general protected area, look for a spot with the right depth: from a few feet deeper than the draft of your boat (at low tide) to as deep as 30-40 feet if necessary—if you have at least 200-300 feet of anchor rode.
• Make sure you are well clear of any channel regardless of how the boat swings with wind shifts, and that there are no hazards if your boat were to swing in a full circle around the anchor.
• When other boats are already anchored nearby, follow good anchoring etiquette to stay safe without risking collision or entanglement. The general rule is that the first boat in an anchorage can choose its spot at will and each subsequent boat must stay clear of others already present.
• Calculate how much swinging room you may need if the wind changes, based on how much anchor rode you will pay out according to the water depth. If possible, make sure your swinging circle does not overlap with any other boat’s swinging room.
• In a crowded anchorage where your swinging room may have to overlap another boat’s, choose a spot among similar boats. Most cruising sailboats with a keel will swing in the same direction at the same time and therefore should not collide if not positioned too close together. But a shallow-draft powerboat will swing on the wind differently from a keel sailboat, increasing the risk of collision if their swinging circles overlap.

3. Approach Slowly

• Although you can learn to anchor under sail, most cruising boats lower or furl the sails before making the approach into the anchorage, and anchor under power. Using the engine also gives you more control if a last-minute maneuver is needed.
• Approach your planned spot into the wind, keeping an eye on your depthfinder or chartplotter to ensure you are where you want to be on the chart. If there is a strong current in the area that affects the boat more than the wind, approach into the current instead.
• As you near the spot, slow down to allow the boat to coast to a stop. If you come in fast and have to use the engine in reverse to stop, there’s a good chance the boat may pivot or turn during the reversing, and the boat then will not at first pull directly back on the anchor. There’s seldom any reason to be in a hurry at this point.
• Double-check to make sure you are not too close to another boat and are at the intended depth. If you decide you need to move to either side, circle back around to make your approach again to the new spot upwind or current.

4. Lower, Don’t Drop, the Anchor

• Wait until the person at the helm says the boat has stopped completely and is starting to move backward on the wind or current before lowering the anchor. (Watch your GPS speed if you’re not sure.) If the boat is still moving ahead, you may accidentally set the anchor in the wrong direction by pulling it ahead instead of drifting back to set it.
• It is important to lower the anchor gradually to prevent the anchor rode from falling down on the anchor flukes and possibly fouling the anchor. In that case you may not realize the anchor has not set well, and if the wind comes up later the anchor can easily drag if fouled. Never just toss the anchor over hoping for the best!
• You can tell when the anchor reaches the bottom because of the reduced strain on the rode. Pause a moment to let the boat move back and pull the rode tight. If the boat is floating motionless in the absence of wind and current, tell the person at the helm to put the engine in reverse to start the boat backward. Your goal here is to align the anchor correctly on the bottom, with its shank pulled back in the direction in which the boat will lie at anchor. Otherwise, the anchor chain may foul the shank or flukes and prevent the anchor from setting well.

5. Set the Anchor

• Making sure the anchor is well set (that is, dug in well in the bottom) is the most important part of anchoring. The anchor holds the boat by digging its flukes into the bottom, not by just lying there like a weight on the bottom. If the anchor is not set, the boat may seem well anchored until the wind comes up—when the anchor will then bounce along the bottom as the boat drags toward a hazard.
• As the boat moves backwards due to wind, current, or the engine’s power in reverse, gradually pay out the rode. Always keep a light tension on the line, but don’t yet clinch it tight. (If you tighten the rode too soon, the anchor will be pulled upward and out of the bottom and will not set.)
• Visualize the anchor rode pulling straight back on the anchor shank as the point(s) of the anchor fluke(s) dig in. If your anchor rode is all chain or has a section of chain at the anchor, the pull will be more nearly horizontal along the bottom. This is how anchors are designed to dig in and hold.
• When you have about 3 times as much anchor rode out as the water depth (a scope of 3 to 1), temporarily cleat or cinch the anchor rode at the bow and let it pull tight. Keep a hand on the rode to feel the tension. The boat should stop and the rode feel very tight, indicating the anchor has set. If the anchor has not set, you will feel the tension in the rode come and go or feel its pull changing as the anchor bounces along the bottom.
• If the anchor has set, continue with the next step of paying out scope. If it has not set, you can also continue but must be very careful to ensure the anchor digs in when you have the proper scope. If the anchor has not set yet with about a 3 to 1 scope, many sailors prefer to hoist it now and try again rather than letting out more anchor rode and having to bring it all back up to try again later.

6. Pay Out the Proper Scope

• Continue paying out the rode as the boat moves backward, until you reach the desired scope. Many factors affect the scope needed, including the type of boat, the type of anchor, whether the rode is all chain or a combination of chain and line, the characteristics of the bottom, and the wind predicted.
• As a general rule, most cruisers prefer a scope of 7 to 1 for safe anchoring overnight. For a lunch stop in a calm anchorage, a scope of 5 to 1 or less may be sufficient, assuming someone stays on the boat in case the wind increases dramatically. With higher winds or big waves, a scope as high as 10 to 1 may be appropriate. Remember that the scope should be based on the high tide water depth. If you anchor at low tide in 10 feel of water and the depth 6 hours later is 20 feet, your scope then would be only half of what it was.
• Once you have the proper scope, back down hard on the anchor using the boat's engine to ensure it is well set. The rode should be very tight and not give at all while backing.
• Scope can be adjusted later if conditions change, simply by letting out more rode if desired. This increases your swinging distance, of course, so you should confirm you will remain far enough away from other boats or hazards.

7. Check the Anchor Periodically

• Even when you’re sure the anchor is well set, changing conditions can result in the anchor dragging. Before relaxing completely for the night, make sure you can tell later on if the boat is dragging.
• Your GPS or plotter can reveal changes of position, although small changes may not be noticeable or may be interpreted as just swinging in a different direction. If possible, take sightings on at least two features on shore (choose something that will be visible at night) and note the compass bearings to each. If these bearings change significantly later, you may be dragging. A smartphone or tablet app like My Anchor Watch can also help ensure you know it if your anchor is starting to drag.
• Another technique used by old-timers is to let down a small second anchor or weight from the stern just to the point where it rests on the bottom, and then drape it over the boom and dangle a noise-maker like a bucket or pot tied to the free end. If the boat moves very far, the line will pull the noisemaker over the boom to clang down into the cockpit, hopefully waking you to take action if needed!
• If you suspect you may be dragging, check the anchor rode at the bow. You may feel or see changes in its tension if the anchor is bumping over the bottom. If you have any evidence of dragging, monitor the situation very carefully. In calmer conditions the anchor may reset, but with gusty or heavy winds it will likely not dig in by itself, and you may have to hoist the anchor and move to a new position and start over.
• Finally, in an emergency situation if the anchor is dragging or a gale puts you at risk of dragging—particularly against a reef or lee shore—you can avert disaster by running the engine slowly in forward gear to take some of the strain off the anchor rode.

A common anchoring problem occurs if the anchor's flukes hook under a rock, chain, or other bottom debris and prevent the anchor from being hoisted. Try backing pulling the anchor up from the opposite direction in an attempt to free it. The best solution is to use a  trip line  or the  AnchorRescue  retrieval device to prevent the risk of losing your anchor should it become snagged.

Anchoring involves a number of skills, which improve with experience. Many books have been written on the subject, and when cruising in unfamiliar waters or far from home where you may be caught in a tricky situation, it’s a good idea to have a book on anchoring or seamanship on board to consult for appropriate techniques in unusual circumstances.

Anchoring Made Easy: A Newbie’s Guide to Securing Your Sailboat

What is anchoring?

Anchoring is a fundamental aspect of boating that involves securing your sailboat in a specific location using an anchor and chain.

When you anchor your sailboat, you are essentially creating a stable and secure position for your boat, regardless of the wind or current.

Table of Contents

Can you anchor a sailboat anywhere?

No, you can’t anchor just anywhere.

• First and foremost, you need to be aware of any regulations or restrictions in the area you plan to anchor.

Some harbors, marinas, or waterways have specific rules regarding anchoring, and it’s important to respect these guidelines.

• In addition, you’ll need to consider the bottom conditions.

Anchoring in rocky or weedy areas can make it difficult for your anchor to dig in and secure your sailboat . Ideally, you’ll want to find a sandy or muddy seabed, as these provide better holding power for anchors .

• Furthermore, you should avoid anchoring in areas with heavy boat traffic.

Not only can this increase the chances of collisions, but it can also make it difficult for you to safely drop and retrieve your anchor.

Choosing the Right Anchor and Chain Size

The size and weight of your anchor will determine its ability to hold your boat securely in place, while the chain provides additional weight and strength to keep the anchor in position.

So, how do you choose the right anchor and chain size for your sailboat?

• First, consider the size and weight of your sailboat .

Larger boats require larger anchors and chains to provide adequate holding power.

As a general rule of thumb, it’s recommended to use an anchor that weighs 1 pound for every 2 feet of boat length.

So, if you have a 30-foot sailboat, a 15-pound anchor would be appropriate.

• Next, think about the type of bottom you’ll be anchoring in.

Different anchor designs work better in different types of seabeds, such as sand, mud, or rocks.

For sandy bottoms, a fluke or plow-style anchor is often recommended, while a grapnel or claw anchor is better suited for rocky bottoms.

Picking the Right Spot to Anchor

Choosing the right spot to anchor your sailboat is essential for a safe and enjoyable experience on the water. Whether you’re planning a short stop or an overnight stay, finding the perfect location can make all the difference.

So, how do you pick the right spot?

• First, consider the depth of the water.

You’ll want to find a spot with enough depth to accommodate the draft of your sailboat, plus some additional clearance to account for tides or changes in water levels.

Consult nautical charts or use a depth sounder to determine the water depth in the area you plan to anchor.

• Next, assess the bottom conditions.

Look for a sandy or muddy seabed, as these provide better holding power for anchors.

Avoid areas with rocky or weedy bottoms, as they can make it difficult for your anchor to dig in and secure your sailboat.

• Consider the surrounding environment as well.

Look for sheltered areas or natural features such as coves or bays that can protect from strong winds or currents . These areas will offer a more comfortable and secure anchorage for your sailboat.

Preparing Your Sailboat for Anchoring

When preparing your sailboat for anchoring, there are several important things you need to do to ensure a smooth and successful docking experience.

Here are four essential tasks to complete before dropping your anchor :

1. Check your equipment: Before setting sail, make sure you have all the necessary anchoring equipment on board.

This includes an anchor, chain, and any additional gear such as a buoy or buoy line. Inspect your equipment to ensure it is in good condition and free of any damage or wear.

2. Secure loose items: Stow away any loose items on your sailboat that could become a hazard during the anchoring process.

This includes things like ropes , fenders, or loose equipment. Secure these items in designated storage areas or tie them down to prevent them from shifting or falling during anchoring.

3. Clear the deck: Remove any obstructions from your deck that could interfere with the anchoring process.

This includes items like cushions, coolers, or other personal belongings.

Clearing the deck will provide you with a clean and clutter-free area to work in when dropping anchor .

4. Prepare your crew: Brief your crew on their roles and responsibilities during the anchoring process.

Make sure everyone knows where to be and what to do when it’s time to anchor.

Assign specific tasks to each crew member, such as handling the anchor or controlling the helm, to ensure a coordinated and efficient docking experience.

The Step-by-Step Guide to Anchoring Your Sailboat

Follow these instructions, and you’ll be able to safely and effectively anchor your boat in no time.

1. Choose your anchor location

Before you start the process, select a suitable location to drop your anchor . Consider factors such as water depth, bottom conditions, and nearby hazards.

Once you’ve chosen the spot, approach it slowly and stop the boat when you’re in the desired location.

2. Prepare your anchor and chain

Make sure your anchor is ready for deployment. Remove any tangles or knots in the chain and ensure it’s securely attached to the anchor.

Double-check that the anchor is properly stored and accessible for deployment.

3. Determine the amount of anchor chain

Decide how much anchor chain you need to deploy based on the depth of the water.

A general rule of thumb is to use a ratio of 5:1 or 7:1 for the length of the anchor chain to the depth of the water. For example, if the water is 10 feet deep, deploy 50 to 70 feet of chain.

4. Drop the anchor

Carefully lower the anchor over the bow of your boat while paying out the chain.

Use a controlled speed and avoid letting the chain drop too quickly, as this could damage your boat or the anchor.

Make sure the anchor hits the bottom before releasing the chain.

5. Set the anchor

Once the anchor is on the bottom, put the boat in reverse at idle speed to ensure the anchor is firmly embedded.

Give it some time to settle and check that the boat is staying in position. Use a landmark on shore or your GPS to monitor any drifting.

6. Secure the anchor

Once you’re confident that the anchor is set, cleat off the chain or secure it to a bow cleat to prevent any accidental movement or slippage.

Double-check that the anchor is holding by slowly reversing the boat to put some pressure on the anchor.

• Congratulations! You’ve successfully anchored your sailboat. Remember to monitor your position and the anchor’s holding power throughout your stay. If you need to reposition or adjust the anchor, follow the same steps in reverse order.

How long can you be at anchor for on a sailboat?

In general, you can stay anchored for a few hours or overnight, but it’s important to check local regulations to ensure compliance.

Some areas have time limits for anchoring or require permits for longer stays.

Additionally, you’ll need to consider the weather forecast. If there are strong winds or rough seas expected, it may not be safe to remain anchored for an extended period.

What side of the vessel you should never anchor?

There is actually one side you should avoid at all costs: the bow , or the front of the boat.

Anchoring on the bow can lead to several problems and safety hazards.

Firstly, it can interfere with the boat’s steering and maneuverability, making it difficult to control the vessel in tight spaces or when approaching docks .

Secondly, anchoring on the bow can cause the boat to swing in unpredictable directions, especially when wind or currents change.

This can increase the risk of collision with other boats, docks, or hazards in the water.

To avoid these issues, always anchor your sailboat off the stern, or the back of the boat. This allows for better control and maneuverability, as well as a more stable anchoring experience.

Additionally, anchoring off the stern keeps the bow free for easy boarding and disembarking, making your sailing experience more convenient and enjoyable.

What happens when a sailboat drag anchor?

When a sailboat drags an anchor, it means that the anchor is no longer holding the boat in place.

This can occur for several reasons, such as changing wind or current conditions, a poorly set anchor, or inadequate anchor line length.

As the boat starts to drift, it can potentially collide with other boats, docks, or even run aground.

In this situation, it’s important to act quickly and calmly.

First, assess the immediate surroundings to determine any potential dangers or obstacles.

Then, try to reset the anchor by moving the boat in the opposite direction of the drift and dropping the anchor again.

If this doesn’t work, you may need to find a new anchorage or consider alternative methods, such as using a second anchor or seeking assistance from nearby boaters.

How To: Basic Anchoring and Anchoring Etiquette

By: Zeke Quezada, ASA Cruising Tips , Learn To Sail

Quite a long time ago…decades ago. I sailed over to Catalina Island from my marina near ASA headquarters. I was young. It was my first time embarking across the channel. My crew was a good friend and his cousin who was celebrating his 21st birthday. They drank beers the entire time. 

In simple terms, I was a solo sailor.  I was also young and irresponsible.  Why admit to this? Well, we all were young once and we all made dumb decisions. Own it and learn from it.

Did I understand anchoring? No. Up to that point, I had only ever picked up a mooring ball once in my sailing life.  This was way before Youtube videos explained how to drop the hook.

Frankly, ASA bite-sized lesson on Anchoring Basics would have been perfect for me.

ASA 101 Basic Keelboat sailing will prepare you for Basic Anchoring principles. However, let’s refresh some of that knowledge on how to drop and set an anchor on a sailboat.

First, a few basic anchoring tips to start:

• Make sure you know where the anchor is stowed.
• Make sure you know how to get it in the water safely.
• Make sure you know how much rode you need to pay out. 
• Make sure you know how to make the rode fast on deck.

Basic Anchoring

Anchors work by digging themselves into the seabed. To do this, they need the rode to pull at an angle closer to horizontal than to vertical. 

Anchoring Vocabulary:

• Rode:   The rope and/or chain that connects it to the boat
• Scope:  The ratio of the length of rode let out to the depth of water. 
• Make Fast: To secure, as when typing a line to a cleat.

As you drop the anchor you will need to pay out a significant amount of rode to allow for the rode to pull at an angle that is close to horizontal.  This is called the scope.  Typically, a 7 to 1 ratio works.  This number will get adjusted depending on conditions. (A lesson learned in ASA 103, ASA 104)  

To arrive at the right length of rode to let out, you add the height of the boat’s bow above the water to the depth. For example, if the depth is 10 feet and the freeboard at the bow is 4 feet, the length of rode needed for 7:1 scope will be (10 + 4) x 7 = 98 feet.

TIP : “When in doubt let in out” works well in anchoring.

Stand well clear of the anchor rode when letting go of the anchor—anchors are heavy, fall quickly through the water, and the rode can cause, at the least, a nasty rope burn

Anchoring: Step-By -Step

• Approach your chosen spot for anchoring by bringing the boat to a stop, head to wind. 
• With the boat stopped, lower the anchor and pay out the rode as the boat blows downwind.
• When enough rode has been let out, make the rode fast.
• The anchor will take hold and the boat will lie head to the wind or current.
• The anchor is set.

Anchoring Etiquette

A few years ago Sail-World.com published a great article on Anchor Etiquette and it is still very relevant.

1. The first boat sets the precedent:

If you arrive in an anchorage and find that all the boats have a stern anchor set, that’s now the rule. If the first one there is a cabin cruiser that yaws all over the place and they have 60 metres of rode out in five feet of water, they have set the precedent. Any subsequent comers will need to give them room.

2. Watch your Wake:

Entering an anchorage or a mooring area is like moving into a new neighborhood. Enter at a slow speed, less than five knots, to avoid making a wake that might upset their sundowner drinks or the bits from the winch they were servicing, or dinner preparations. This also applies to dinghies when traveling close to anchored boats – and in most countries, it’s the law anyway.

3. Give yourself, and other boats room:

Look at the wind in the anchorage and try to work out where the anchors of other boats are lying. Cruise through the anchorage a couple of times to assess the situation. Calling out to find out how much chain the boat has out is an indicator that you are aware of swing patterns and will attempt to place your boat so that it is not in the way of another boat. There’s also some self-preservation here too, as you may want to stay clear of potential party boats, or the boat with that very noisy wind generator. Remember, if he was here first, you are the one who has to move.

4. Watch the ‘Magnet Effect’:

A boat already anchored seems to attract the next boat to anchor right next to it, even though there is an enormous empty bay to anchor in. Try not to do this, and, if you were there first, it is your right to speak to a boat that arrives after you and ask them to move if you feel that they are too close.

5. Buoy your anchor:

In a crowded anchorage, it’s a good idea to buoy your anchor – place a floating marker on your anchor so that you, and others, know where it is. There’s nothing worse than tangled anchors, particularly if you have to make a hasty departure because of deteriorating conditions. (Of course, you have to keep a small watch to make sure your first-time sailor doesn’t arrive and try to pick it up as a mooring ball.)

6. Sound carries far:

Voices, music, engine noise, especially outboard motors, unmuffled go-fast boats, ski boats, jet skis, generators, barking dogs and the dreaded ringing telephone are all examples of the egregious disruption of anchorage serenity. Common sense should prevail in predicting what will not be appreciated and protecting the serenity for the common good.

7. Keep Bow to Cockpit communications civil:

It’s not the anchoring, or the need to re-anchor, which separates the beginners from the experts. It is the amount of yelling and chaos that breaks out between the person handling the anchor and the person maneuvering the boat. Boating is the only sport that requires T-shirts that proclaim ‘Don’t yell at me!’ Either develop a set of hand signals or better still, use some inexpensive walkie-talkies, so that at least your comments on the abilities of your other crew member will be kept on your boat.

8. Think of your neighbors AND the environment:

The smell of burgers on the grill might be a marvelous aroma for most, but really smelly cooking upwind of a boatload of vegetarians may be a cause for some strong sentiments. Don’t go into a crowded anchorage full of pristine water and then not use the holding tank! – It’s really not a good scene for swimmers in the water. And it can ruin your whole day to find yourself swimming with rotten tomatoes or floating banana skins.

9. Be careful with lights at night:

When anchored at night always have an anchor light on (black ball during the day), when looking for an anchorage don’t shine a strong beam directly into another boat’s cockpit, and don’t be the boat that’s lit up like a football field deep into the night when all else in the anchorage are trying to sleep.

11 Steps To Anchoring Your Sailboat Safely

Knowing how to anchor a sailboat properly is an essential skill every sailor must learn. As a solo sailor, I frequently anchor my 41-foot sailboat alone. With some practice and a good plan, it is pretty simple in most normal situations. However, there are a few things that you need to pay extra attention to and some cases and conditions that require knowledge to get right.

These are the steps to anchor your boat safely:

• Plan and research the location you want to anchor.
• Identify obstacles and hazards in the area.
• Get the anchor ready.
• Locate the spot you want to anchor, preferably a sandy patch.
• Navigate to your place and set the boat up against the wind.
• Aim at your spot and drop the anchor at the bullseye.
• Pay out your scope of chain and rig up your snubber or bridle.
• Tension up the chain and set the anchor.
• Test your ground tackle’s holding.
• If the test fails, pick up the anchor, return to step 4, and repeat the process.
• Optional: Inspect that the anchor is adequately dug into the seabed.

Let’s break down the steps and go into detail.

11 steps to anchor your sailboat safely

Anchoring is a hot topic amongst cruisers, and there are several ways to do it properly. The steps in this guide are guidelines and should give you the theoretical knowledge to understand the process even if the conditions differ. This method is doable alone but is easier with a pair of extra hands. The basics are the same, no matter how many hands you have on deck, though.

How you anchor depends on the weather conditions and if you can see the seabed you want to put the anchor in. It is easiest if you can see what type of bottom you have. If the visibility is terrible, you’re basically throwing spaghetti at the wall to see what sticks.

I have spent many years in the North Sea on commercial anchor handling vessels, installing massive anchors for oil platforms and FPSOs in various conditions. We anchor our sailboats using the same principles but on a smaller scale. My professional experience means that I know a thing or two about anchoring. Years of anchoring Ellidah single-handed, in addition to the above, means I have made some mistakes and learned from them.

1. Plan and research the location you want to anchor

The first step in safe anchoring is planning and research. Gain some knowledge of the place you plan to anchor. Ensure that anchoring is allowed; some areas are protected and illegal to anchor in.

Figure out the level of protection from the weather, water depth, and seabed conditions. Also, make an escape plan in case of emergency – conditions change quickly, and your escape plan may save you and your boat someday.

In the scenario for this guide, we are alone on board and will drop the anchor at 10 meters depth on a small sand patch in an area with a lot of seaweed in moderate wind.

2. Identify obstacles and hazards in the area

The next thing you want to be aware of is if there are any rocks, reefs, shallows, buoys, and other dangers in the area. Your charts often give detailed information about what to expect in the anchorage.

If you use Navionics on your device, the Active Captain community will have valuable information about the anchorage and what to be cautious about. The information is written by other sailors and is invaluable to help you get an overview of the anchorage.

Another app I highly recommend is Navily. Navily informs about anchorage locations, conditions, and protection levels. I actually wrote an in-depth review of these apps that I highly recommend you read!

3. Get the anchor ready

When you have done your planning and research, it is time to get the anchor ready to drop. Put on your autopilot or lock the rudder on a clear course. Head up to the bow and prepare your anchor to be dropped.

I prefer to lower the anchor into the water and hang it below the surface. If you leave it in the air, it might bounce into your bow, and we want to avoid that.

We also don’t want the anchor hanging deep enough to catch on to something before we have found our anchoring spot and navigated the boat into position.

Return to the cockpit when the anchor is ready and take back manual control.

4. Locate the spot you want to anchor

Take the boat for a swipe around the area and look for a sandy area to place the anchor. When you find a good spot, take note of the depth and decide your scope.

Consider your distance from the surroundings, and ensure you have enough room to swing around without hitting anything or bumping into another boat. Please give yourself a little bit of extra space. No one likes it when someone anchors too close to them.

Pro Tip: When we say scope, we refer to the amount of chain you put out in relation to the water depth. I always recommend at least five times the water depth – 5:1 or more, but if you are in a tight anchorage that is well-protected and the seabed holding is good, you may get away with less. I never go lower than 3:1 and always put out a minimum of 30 meters of chain.

5. Navigate to your spot and set the boat up against the wind

Position the boat so you can approach your location with the bow against the wind.

Here comes the tricky part: Depending on how much wind you have and how big of an area you have to drop the anchor in, you need to consider how far the boat will drift in the time it takes you to leave the helm and get up on the bow to start lowering the anchor.

You may want to drive ahead of the spot and position the bow with a slight offset to either side. Now, say you are 10 meters ahead and slightly to starboard of the spot. Stop the boat and turn the bow slightly to the port.

Lock the rudder, head back up to the bow, and get ready to drop the anchor. The wind will catch the starboard side of the bow and push it over to port, and by the time you are prepared at the bow, you should be approaching your spot.

6. Aim at your spot and drop the anchor at the bullseye

As soon as you are positioned at the bow, start paying out the chain, but leave the anchor just above the seabed until it is right above your sandy patch. Once the anchor is in position, land it on the seabed and continue paying out the chain as the boat drifts along.

If you miss the spot, lift the anchor to just below the surface again and reposition yourself.

Don’t stress this step. It is perfectly normal to make several attempts. People on other boats will probably pay attention to you and sometimes even shout, but ignore them for now. You are anchoring and can only do one thing at a time.

Get ready for a new attempt and repeat steps 4 and 5 until you hit the bullseye.

If the entire seabed area is nice and sandy, you can skip step 7 and drop the anchor in any decent position.

7. Pay out your scope of chain and rig up your snubber or bridle

Now that the anchor is placed perfectly in your sandy patch continue to pay out the chain as the wind pushes the boat back. Count the chain length and continue to pay out until you reach your scope of 50 meters for this example.

You may have to stop and wait for the boat to drift if there is little wind or even head back to the helm to reverse the boat. We don’t want to make a pile of chain in one spot, but lay it out nicely.

Once the entire scope of the chain is out, it is time to rig up a snubber.

Pro Tip: A snubber is a rope or bridle you attach to the chain and secure to the boats’ cleats. We use snubbers and bridles to take the load off the windlass. Ideally, we want the boat to hang off strong cleats instead of the windlass.

8. Tension up the chain and set the anchor

Now that your snubber or bridle is rigged up, head back to the helm and put the engine in reverse. Take your time and wait for the chain to get stretched out.

You will feel when the boat comes to a stop, and now is time to make a note of your exact location while you keep the engine at low revs in reverse to keep the tension on the chain.

There are two easy ways to take note of your position:

• Find a spot ashore and another place between yourself and the shore spot that lines up to each other.
• Add a marker to your chart plotter or start a snake trail. I like this method.

Increase the reverse revs on the engine slowly and ensure that the boat stays in the exact location. We want to ensure the anchor isn’t dragging through the seabed. Continue to increase the revs up to the rpm you usually use for motoring at marching speed.

For a Volvo Penta or Yanmar engine, you typically end up at 1800-2200rpm.

9. Test your ground tackle’s holding

Term: ground tackle.

When we say ground tackle, we refer to everything holding the boat to the ground. In this case, it is the snubber, snubber shackle, chain, chain shackle, and anchor. You can learn more in The Sailors Guide to Nautical Terms by clicking this box.

Now, we’re going to test that our ground tackle is holding. Keep the revs up and monitor your two aligned spots or markers on the chart plotter for 30-60 seconds. If you haven’t moved during this period, your anchor has dug into the seabed and is holding.

Slowly ease off the throttle until the engine is back in idle. The boat will start to move forward as the weight of the chain pulls the catenary down. Once the boat stops, the wind will push the bow to the side and swing you over until the chain is stretched up again. Be patient and let the vessel settle.

Well done, you should now be safely anchored! Unless your anchor dragged, which is pretty normal.

10. If the test fails, go back to step 4 and repeat the process

If the anchor breaks loose during the process, you will see that your two aligned spots will start to unalign, or you will drift away from the marker on the chart.

Sometimes, you’ll feel a slight bump in the boat as the anchor loses grip and notice you aren’t holding the same position.

Pro Tip: A good trick is to head up to the bow and put your hand on the snubber or bridle while keeping the reverse tension. You will feel a vibration if the anchor drags through the seabed and hear scratching if the anchor rubs against rocks.

If the test fails and the anchor is dragging, you must take the anchor and chain back up and start over from step 5.

However, if you have made several attempts in the same spot without any luck, you may have to find another location and start again at step 4.

When you get more experience, you will realize that some anchorages can be harder to anchor properly in than others. It is part of the game to have some failed attempts, and I have spent hours and countless attempts on more occasions than I can count.

Do NOT give up until your boat is properly and safely anchored! It is a recipe for disaster, and how people lose their boats. A 50-knot squall may come out of nowhere and surprise you, even on a lovely sunny day. Yes, I speak from experience!

11. Optional: Inspect that the anchor is adequately dug into the seabed

You are usually pretty safe after testing the ground tackle by reversing, but there is one last thing I like to do to be 100% sure that the boat is safely anchored. Now, I cruise in the tropics, where the water is usually clear and delicious, so this step may not apply to you.

Jump in the water with a mask and snorkel, follow the chain to where the anchor is, and ensure it has adequately dug into the seabed. I quite enjoy this exercise, and it gives me great confidence. After countless dives, I know pretty well how my anchor behaves in different seabed conditions.

Optional 2: Have an anchor drink

If you ever sail with a Norwegian, you will probably come by the term “Ankerdram,” which means Anchor Drink. You celebrate a successful anchoring by having a nice beverage of your choice. Since I am Norwegian, I like to practice this tradition with a cold beer!

Final Words

The key to proper and successful anchoring is to do it thoroughly and correctly. If you don’t do it properly, you risk the boat drifting out to sea with or without you onboard. Or even worse, into another vessel or onto the ground!

I was anchored in Ibiza when a charter boat started dragging and crashed into Ellidah without anyone onboard. We handled the situation and saved the charter boat, but the skipper was clueless about anchoring and told me that he usually just dropped the anchor and a bit of chain on top of it, and that was that.

Another time, me and a friend were anchored in the Holandese Keys in San Blas on a gorgeous sunny day. A Backpackerboat was anchored poorly next to us and started to drag rather quickly when a sudden 50-knot squall came through violently. We had a massive choral reef behind us, which the backpacker boat was only inches from hitting.

Don’t be like those guys . Anchor correctly EVERY time!

Take some time to practice and perfect your anchoring skills. Eventually, you will master how to properly anchor a boat like it is the most natural thing in the world. Sometimes, it may take as little as 10 minutes from your start until you have your anchor drink in your hand!

Anchoring 101: Techniques and Tips for Secure Anchorage

• No Comments

Anchoring is an integral part of the boating experience. Whether it’s a short break to enjoy the surroundings, an overnight stay, or an emergency stop, understanding how to securely anchor your boat is essential for every sailor. A reliable anchorage provides peace of mind, stability, and safety. This article aims to impart a solid understanding of anchoring techniques, covering a range of topics from anchor types and selection criteria to anchoring methods, maintenance, and safety considerations. By the end of this guide, you should be better equipped to make the right anchoring decisions and enjoy a safe and secure boating experience.

Understanding Anchors and Rode

An anchor is more than just a heavy object you drop overboard. It is a carefully engineered device designed to hold a vessel in place even in adverse conditions. There are several types of anchors, each with its unique features and suitable conditions:

• Fluke Anchors (Danforth): Characterized by its flat, fluke-style design, the Danforth is highly effective in sandy or muddy bottoms. Its lightweight and compact design make it a popular choice for smaller boats.
• Plow Anchors (CQR, Delta): These anchors are designed to dig into the seabed and are quite effective in a variety of bottom conditions, including mud, sand, and rock.
• Mushroom Anchors: These are best suited for softer seabeds such as silt or mud. Their design, which resembles a mushroom, allows them to bury into the seabed and provide excellent holding power.
• Grapnel Anchors: Mostly used by smaller boats and kayaks, these anchors are great for rocky or coral bottoms. Their design is not ideal for strong holding, but their lightweight and compact size make them easy to handle.
• Bruce or Claw Anchors: They offer good holding power in most seabeds and are highly resistant to wind and tide changes.

The term “rode” refers to the line connecting the anchor to your boat, and it could be all chain, all rope, or a combination of both .

The choice of rode depends on several factors:

• Boat Size: Larger boats usually require chain rode due to its durability and added weight, which helps in keeping the anchor set.
• Anchoring Conditions: In rocky conditions, a chain rode is preferred because it’s less likely to get cut. In softer seabeds, a rope rode can suffice.
• Depth and Holding Ground: The rule of thumb for rode length is a 5:1 or 7:1 scope, meaning for every foot of water depth, you should have 5 to 7 feet of rode out.
• Storage: Rope is lighter and takes up less space, a factor that can be crucial in smaller boats.

Understanding the differences between these anchors and the factors affecting your rode choice will help you make informed decisions on what’s best for your specific needs.

Choosing the Right Anchor

Selecting the right anchor involves a consideration of several factors. Not all anchors are created equal, and what works well in one situation might be inadequate in another. Here’s what to consider when choosing your anchor:

• Boat Size: Larger boats require anchors with greater holding power. Use your boat’s length and weight as a guide, but consider its windage as well. High-sided boats catch the wind and will need a more robust anchor.
• Bottom Conditions: Different anchors perform best in specific seabed types. For example, a fluke anchor performs well in sandy or muddy bottoms, while a plow anchor is versatile enough to handle various conditions, including rock, sand, and mud.
• Typical Weather and Sea Conditions: If you sail in areas known for their rough weather and high winds, you will need an anchor that can withstand these conditions.
• Storage Space: Some anchors require more storage space than others. Plow anchors, for example, do not stow as compactly as fluke anchors.
• Budget: While it shouldn’t be your deciding factor, the cost of the anchor and its rode is a valid consideration.

Examples of suitable anchor types for different scenarios:

• For a small day-sailer sailing in sandy bottoms, a lightweight fluke anchor might be the best fit.
• A medium-sized cruiser navigating various sea beds could benefit from a plow anchor for its versatility.
• If you’re sailing a large yacht in high windage areas, a heavy plow or claw anchor would be advisable to ensure your vessel remains secure.

Remember, many seasoned sailors carry more than one type of anchor to be prepared for various scenarios. Your choice of anchor can significantly influence your boating experience, affecting your safety and peace of mind. Therefore, it’s essential to make an informed choice based on the unique needs of your vessel and sailing conditions.

Selecting an Anchorage Spot

Finding the right anchorage spot is as crucial as having the right anchor. Below are some factors to consider when choosing where to anchor:

• Depth: You’ll need sufficient depth to allow for tide changes. However, the deeper the water, the more rode you’ll need to let out for a good scope.
• Sea Bed: Sand and mud usually offer good holding grounds for anchors. Rocky or grassy bottoms, on the other hand, can present more challenges.
• Weather: Before you drop the anchor, check the weather forecast. If the wind or current is expected to shift significantly, you’ll need to ensure the spot you’ve chosen is still protected under the new conditions.
• Tide: Take note of the tide and its expected changes. You’ll need to account for how it will affect the depth and your boat’s position.
• Surrounding Hazards: Be aware of any nearby hazards. These might include shallow areas, underwater cables, or busy channels.
• Swing Room: Make sure you have enough space to swing with the wind and tide without hitting anything.
• Distance from Other Boats: Ensure you leave enough space between you and other boats. Remember, different boats can swing differently on the anchor.

Tips for safe anchoring:

• Always lower the anchor slowly and gently to avoid it hitting the bottom with a force that might cause it to bounce and not set correctly.
• When you believe the anchor has set, do a “pull test” by pulling on the anchor rode with the engine in reverse at low RPM.
• Once anchored, take note of reference points in relation to your boat. These can help you know if your anchor is dragging.
• Always set an anchor watch – an alarm that lets you know if your boat drifts outside a certain radius.

Remember, the safety and comfort of your anchorage spot are paramount. You need a place where your anchor will hold, and your boat will be safe from weather and any other potential hazards.

Anchoring Techniques

Anchoring a boat is a skill that improves with practice. Below are the basic steps to deploying an anchor and a brief overview of different techniques for varying conditions.

Steps to Deploy the Anchor:

• Select the Spot: Choose your anchoring location considering the factors discussed above (depth, sea bed, weather, tide, etc.)
• Prepare the Anchor: Ensure the anchor rode is free of tangles and ready to be deployed.
• Approach Slowly: Motor up to your chosen spot slowly and into the wind or current, whichever is stronger.
• Lower the Anchor: Once you’re at the spot, lower the anchor smoothly and gently into the water. Never throw the anchor over as it can lead to tangles.
• Reverse and Set: Once the anchor reaches the bottom, reverse slowly while letting out more rode. When you’ve let out enough scope (usually a ratio of at least 5:1), put the engine in reverse and slowly increase the power to set the anchor.
• Check and Adjust: Check if the anchor is holding by looking at fixed points on the land. If it’s not, you’ll need to reposition and try again. Once the anchor is set, adjust the scope if necessary, considering changes in tide and weather.

Different Anchoring Techniques:

Different conditions and situations call for different anchoring techniques:

• Bow Anchoring: This is the most common form of anchoring where the anchor is deployed from the bow of the boat. This technique is typically used because the bow is designed to cut through waves and is generally the most seaworthy end of the boat.
• Stern Anchoring: This technique is used when you want the stern of the boat facing the shore. This is typically in calm conditions and when the shoreline has a beach.
• Bahamian Moor: This technique involves using two anchors set in opposite directions. This is particularly useful in narrow channels where the tide changes direction.
• Two Anchors Off The Bow: In heavy weather or when the anchorage has a rocky bottom, setting two anchors off the bow can provide extra security.
• Mediterranean Mooring: Common in the crowded harbors of the Mediterranean, this method involves dropping the anchor and then backing toward the dock or quay.

Each anchoring technique has its own strengths and should be chosen based on the conditions and your specific needs. Always ensure your anchor is securely set and remember to keep a watch to detect any dragging.

Setting the Anchor

Setting the anchor refers to the process of ensuring the anchor is securely lodged in the seabed, providing a firm hold for your boat. It’s a crucial part of the anchoring process because an improperly set anchor can lead to the boat dragging, potentially causing collisions or running aground.

Here’s how to ensure the anchor is set properly:

Steps to Set the Anchor:

• Slowly Pay Out the Rode: Once the anchor is dropped at your chosen spot, slowly pay out the anchor rode as your boat drifts back with the wind or current. This allows the anchor to descend straight down and lay out properly along the seabed.
• Determine the Right Scope: The ‘scope’ is the ratio of the length of rode you let out to the depth of the water. Typically, a scope of 5:1 is recommended in calm weather, meaning for every foot of water depth, you let out five feet of rode. However, in windy conditions or choppy seas, a higher scope of 7:1 or even 10:1 may be necessary for a more secure hold.
• Set the Anchor: To set the anchor, apply a gradual reverse force to the rode using the boat’s engine. This helps to dig the flukes of the anchor into the seabed.
• Check the Set: To make sure the anchor is properly set, look for fixed points on shore (like a notable tree or rock) and check that your position relative to these points doesn’t change over time. You can also use your boat’s GPS to monitor for any significant movement. If you notice your boat moving, it’s a sign that the anchor isn’t properly set, and you may need to reposition and try again.
• Set an Anchor Watch: Even after the anchor is set, it’s important to continue monitoring for any signs of dragging, especially if the weather conditions change. An anchor watch isn’t just about physically watching; it can also involve setting an alarm on your GPS to alert you if the boat moves out of a defined area.

Remember, setting the anchor isn’t a ‘drop and forget’ process. It requires careful attention to ensure that your boat stays safe and secure.

Monitoring Your Anchorage

Monitoring your anchorage is crucial for ensuring that your boat stays secure. Even the best-placed anchors can sometimes dislodge due to changes in weather, tide, or sea bed conditions. Regular checks can provide early warning of any problems, allowing you to take corrective action if needed.

Here are some tools and techniques you can use to monitor your anchorage:

1. GPS (Global Positioning System): Most modern boats are equipped with GPS, which can be a great tool for anchor watch. You can set an anchor alarm on your GPS to alert you if your boat moves outside a predefined area. This feature is especially useful for overnight anchorages or in conditions of poor visibility.

2. Mobile Applications (For Android and Iphone)

3. Visual Landmarks: Choosing two or three fixed landmarks (such as distinctive trees, buildings, or other features on the shore) and regularly checking your alignment with them can give you a good indication of whether your boat is drifting.

4. Bearing Checks: A more precise version of using visual landmarks is to take bearings of fixed points with a compass. By regularly comparing these bearings, you can detect even small changes in your boat’s position.

5. Rode Tension: Feel the anchor rode (the line or chain connecting the boat to the anchor). If it’s taut, it could be a sign that your anchor is holding firm. However, if the rode becomes slack, it might mean that your anchor is dragging.

6. Depth Sounder: If your boat is equipped with a depth sounder, this can help you monitor whether the water depth changes significantly, indicating a potential drag.

7. Underwater Camera: Some boaters use an underwater camera to visually check the anchor. However, this method might not be practical for all boaters and conditions.

Monitoring your anchorage should be part of your regular routine whenever you’re at anchor. Remember, the key to a secure anchorage is vigilance!

Retrieving the Anchor

After a peaceful time at anchor, it’s time to weigh anchor and set sail again. Here are the steps to retrieve your anchor safely:

1. Preparation: Before you start the retrieval process, ensure your deck is clear of any trip hazards. It’s also a good idea to put on gloves to protect your hands from any rough or dirty anchor rode.

2. Move towards the Anchor: Start your boat and slowly motor towards the anchor while pulling in the rode. The idea is to get directly above the anchor. Using your boat’s engine will ease the load on your windlass or whoever is pulling in the rode.

3. Retrieval: Once you’re above the anchor, continue to haul the rode until the anchor is clear of the sea bed. Be sure to keep a steady speed; going too fast can cause the anchor to swing and potentially damage your boat.

4. Rinsing and Inspection: As you retrieve the anchor, rinse off any mud or debris. This is also a good time to inspect your anchor and rode for any signs of damage.

5. Secure the Anchor: Once the anchor is onboard, secure it properly before moving off.

Troubleshooting Tips for When the Anchor is Stuck:

Despite your best efforts, sometimes the anchor can get stuck. Here’s what to do if that happens:

1. Gentle Motoring: The first thing to try is to slowly motor your boat in the opposite direction to the one you used when setting the anchor. This could be enough to free it.

2. Change the Pull Direction: If that doesn’t work, try changing the direction of your pull. Move your boat around the anchor, giving a gentle pull from various directions.

3. Use a Trip Line: If you have a trip line installed (a line attached to the crown of the anchor and buoyed on the surface), you can pull on this line to free the anchor.

4. Wait it Out: If the anchor is still stuck, waiting for a change in tide or wind direction can often free it. Be sure to monitor your situation closely if you decide to wait.

Remember, safety should always be your priority. If you’re unable to retrieve your anchor, it’s better to cut your losses (and your rode) than to risk damage to your boat or harm to yourself or your crew. Always carry a spare anchor in case you need to leave one behind.

Anchor Maintenance and Storage

Keeping your anchor and rode in good shape is crucial to ensuring they perform well when you need them. Here’s how to maintain and store them properly:

Regular Maintenance Checks

• Inspect for Damage: Regularly check your anchor for any signs of damage. This includes looking for bent flukes, a warped shank, or any signs of corrosion, particularly if you have a steel anchor.
• Check Your Rode: Inspect your rode, whether it’s chain or rope. Look for signs of wear and tear, such as chafed or frayed spots in a rope rode or rust and weak links in a chain rode.
• Cleaning: After each use, rinse your anchor and rode with fresh water to remove any salt, sand, or mud. This is particularly important for metal anchors and chain rodes, which can corrode if left dirty.
• Lubrication: Lubricate moving parts such as the swivel or shackle to ensure they move freely. Use a marine-grade lubricant for this.

Common Issues:

• Corrosion: This is a common issue, particularly with steel anchors or chain rodes. If you notice rust, remove it with a wire brush and then apply a rust-proof coating.
• Wear and Tear: Over time, your rode can weaken due to constant exposure to saltwater and sunlight, as well as friction from the sea bed or the anchor winch.
• Mechanical Failure: Moving parts can seize or break. Regular inspection and lubrication can help prevent this.

Storing Your Anchor and Rode

• Anchor: Most boats have an anchor locker in the bow where the anchor is stowed. If you have a secondary anchor, it should be stowed in a location where it can be quickly deployed if needed.
• Rode: Your rode should be neatly coiled or flaked in the anchor locker to prevent it from tangling. If you have a rope rode, consider using a rope bag.
• Dry Storage: Before long-term storage, ensure your anchor and rode are completely dry to prevent rust or mildew.
• Accessibility: Wherever you store your anchor and rode, they should always be easily accessible in case of an emergency.

Remember, an anchor is a significant investment and, more importantly, a key safety equipment on your boat. Proper maintenance and storage are well worth the effort to ensure it functions properly when you need it.

Safety Considerations

Anchoring, while often routine, can present its own set of risks and safety considerations. Here’s a look at safety equipment related to anchoring and how to handle anchoring emergencies:

Safety Equipment:

• Gloves: Wearing gloves can protect your hands from rope burns and pinch points when handling the anchor and rode.
• Anchor Ball: An anchor ball is a large, round, black shape hoisted to indicate that a vessel is at anchor. This alerts other vessels to your status.
• Rode Marker: These can be useful for indicating how much rode you have out and can help you maintain a safe scope.
• Anchor Light: An anchor light (usually a white light visible 360 degrees around the boat) is required from sunset to sunrise to signal your status to other vessels.
• Sound Signals: In fog or poor visibility, sound signals such as a fog horn can alert other vessels to your presence.

Anchoring Emergencies:

• Dragging Anchor: If your anchor is dragging, it means it’s not properly set. You’ll need to retrieve it and try to set it again.
• Entangled Rode: If your rode becomes entangled with another boat’s or an underwater obstruction, try to free it carefully. In extreme cases, you might need to cut the rode.
• Unable to Retrieve Anchor: If you can’t retrieve your anchor, it may be caught on something underwater. Try changing your boat’s position to dislodge it. If it’s still stuck, you might need to cut the rode as a last resort.
• Unexpected Weather Changes: If weather conditions deteriorate unexpectedly, you might need to reposition your boat or set additional anchors.
• Collision Risk: If another boat is drifting or motoring towards you while you’re anchored, sound your horn and flash your lights to get their attention. Prepare fenders to minimize impact damage.
• Emergency Anchoring: In an emergency, such as engine failure, you may need to deploy your anchor quickly to stop your boat from drifting onto a dangerous lee shore or into other boats.

Always remember, safety should be your number one priority when anchoring. Regular maintenance of your equipment, vigilance while at anchor, and knowledge of what to do in emergencies can help ensure a safe and enjoyable experience.

What is the best type of anchor for my boat?

The best type of anchor depends on various factors such as your boat size, the seabed conditions where you typically sail, and typical weather conditions. It's a good idea to carry more than one type of anchor to be prepared for different situations.

How do I know if my anchor is set properly?

Once your anchor is dropped, slowly back away to let out the rode. When enough rode is out, gently put the engine in reverse. If the boat starts to move, the anchor is not set. If the boat stays in place, your anchor is set.

How can I retrieve a stuck anchor?

Try changing your boat's position or gently moving in a circle around the anchor point. If it's seriously stuck, you may need to use an anchor retrieval system or even a professional diver.

How much anchor rode should I let out?

The amount of rode you let out, known as the scope, should be between 5 to 7 times the depth of the water, depending on the conditions. More scope may be needed in stormy conditions.

What should I do if my anchor drags in the middle of the night?

If your anchor drags, you'll need to reset it. If it continues to drag, you may need to find a new anchorage spot or use a different type of anchor.

Understanding the Basics of Anchoring

Understanding the basics of anchoring is crucial for sailboat owners. Here are some important points to keep in mind:

1. Choose the right anchor for your boat. Options include fluke, plow, and mushroom anchors. Select one that matches your sailboat’s size and weight.

2. Before dropping the anchor , make sure you are in a suitable location with enough depth and a good holding ground. Avoid areas with strong currents or rocky bottoms.

3. Drop the anchor slowly and steadily , allowing it to reach the seabed. Once on the bottom, let out enough anchor rode to hold securely.

4. Attach a buoy or marker to the anchor rode for easier retrieval later.

5. Set the anchor by gently reversing the boat’s engine. This helps it dig into the seabed and create a strong hold.

6. Regularly monitor the anchor to ensure it stays secure. Keep an eye on the depth sounder and check for any signs of dragging.

7. When it’s time to move , raise and secure the anchor before setting sail.

Understanding the Basics of Anchoring ensures the safety and stability of sailboats while at anchor.

1. Why is Anchoring Important for a Sailboat?

Anchoring is crucial for a sailboat for several reasons, including why it is important for a sailboat.

It provides stability and prevents the sailboat from drifting in open waters.

Anchoring ensures safety during rough weather conditions or strong currents, reducing the risk of accidents or collisions.

It also allows sailors to explore different destinations conveniently and cost-effectively .

Anchoring is important for conservation purposes as it minimizes the impact on marine environments and reduces fuel consumption.

When anchoring a sailboat, it is essential to verify the grip of the anchor by applying reverse pressure to ensure a secure hold.

2. What is an Anchor and How Does it Work?

Table of contents

How to Choose the Best Sailboat Anchor

Choosing the best sailboat anchor on various things such as the type and size of your boat, the type of bottom where you're planning to anchor your boat on, the weather conditions, and many more. For example, anchoring a 24-feet sailing boat on a muddy bottom will not be the same when using the same anchor when anchoring a 49-feet sailboat on a rocky bottom. More importantly, choosing the best sailboat is all about finding the right balance in terms of the size of your boat, the type of the bottom where you're sailing at, the climate conditions, and the amount of time that you're planning to be anchored.

Here is what you need to consider.

The Size of Your Boat

The size of your boat will determine the type of anchor that's appropriate based on its weight and resistance. For example, a claw anchor can be great for boats measuring between 16 feet and 50 feet. In essence, having a bigger boat will require an anchor that is bigger and has more holding power. On the other hand, a smaller anchor with less holding power will be ideal for a smaller boat.

Your Anchoring Time

The holding power of your anchor can be affected by the amount of time you are planning to anchor your boat. If you're planning to anchor your boat for longer periods, it would make a lot of sense to have an anchor with high holding power. Differently, you can go with an anchor with less holding power if you're planning to anchor your boat for a few hours.

The Bottom Type

The shape and sharpness of an anchor will determine how good an anchor can hold your boat in different types of bottoms. For example, claw anchors can struggle in rocks and corals but work perfectly in sand and mud. On the contrary, grapnel types of anchors can work great in rocks but don't work in sand or mud. It all depends on the bottom type of the area you're planning to sail at. 

Anchor Material

The type of material used in manufacturing the anchor is of great importance in terms of its functionality, reliability, and durability.

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!

Boat Anchoring Tips and Techniques

• By Joe Friedman
• Updated: February 20, 2020

There’s a big difference between tossing a “lunch hook” over the side for a quick dip and securing a boat anchor for an overnight stay. What is the proper technique for anchoring? Whole books have been written about proper boat anchoring, and it gets a complete chapter in Chapman Piloting & Seamanship, the venerable guide to small-boat handling. Figuring out boat anchoring is one of the first things you learn in seamanship . Here’s a quick rundown on some solid, basic boat anchoring tips and techniques.

10 Tips Explaining How to Set an Anchor

1. Use Your Engine to Help When Anchoring

The proper technique for anchoring starts with easing the throttle so that the boat is basically standing still at the point where you want the anchor to drop. Let it go, sneak back under power, and slowly pay out the line.

2. Scope Out When Anchoring

You’ll need to know about how much scope to use, since this will affect where the boat will lie once the hook is stuck. Experience and local knowledge of the bottom are the best teachers, but plan on about an 8-to-1 ratio of scope to water depth. Meaning, in 10 feet of water with a 4-foot height to bow from the water, you stream out 122 feet of rode. With more chain and an oversize boat anchor, you may be able to ride reliably to a 4-to-1 scope, whereas poorly holding bottom and/or strong wind and/or strong current may require a 10-to-1 scope. In some cases, tech gadgets can help you set the boat anchor.

3. Head into Current When Anchoring

At dead-slow speed, head the boat up into the wind or current, beyond the spot where you want the boat to lie, at a distance equal to your estimated scope. Come to a stop. In rough conditions , it can pay to drift back without dropping the boat anchor first, so that you can see where the boat will end up when you do deploy the hook.

4. Use Enough Rode When Anchoring

When enough rode is out to equal the desired scope, snub up on the cleat. Allow the stretch to come out of the line and see if you are holding. A shot of reverse gear can often help set the anchor hook but, if done prematurely, can cause the boat anchor to skate across the bottom without catching.

5. Make Sure Your Anchor Holds After Anchoring

With the hook set, cleat it off securely and run the rode through chocks to ensure that navigation lights and other deck equipment don’t get “swept” by the rode as the boat swings on the line. Line up with two landmarks, or use your radar, GPS or depth sounder to monitor your position and ensure that you are not dragging the anchor.

6. Know the Bottom Structure When Anchoring

Your chart or plotter will generally show what to expect, but pockets of the unexpected do occasionally show up in an otherwise defined bottom to make life exciting. The most common bottoms are sand, mud, clay and grass (or weed). Most of the popular anchor styles (Danforth, CQR, Delta, Spade, Bruce, Rocna) are considered to be workable for all of these conditions. That said, plow anchors — like a CQR or Delta — hold best on a rocky bottom, a Danforth holds best in mud, and heavier anchors hold best in grass.

7. What is the Best Anchor Size When Anchoring

The boat anchor should be correctly sized for your boat. For instance, a typical 32-foot medium displacement boat could put out a 25-pound CQR or a 22-pound Delta and be comfortable in 30 knots of wind. A 12-pound Hi-Tensile Danforth is another option. One size up would be nice, especially if you have a power windlass to do all the work. Check the anchor manufacturer’s guide for your boat’s length, displacement and hull type .

8. Rope or Chain When Anchoring

A properly sized all-nylon rode, either twisted or braided, is fine for light-duty anchoring. More common would be to add 6 to 8 feet of chain between the anchor shank and the rode. But for overnighting or extended anchoring, a one-half boat length’s worth of chain is a good rule of thumb to help an anchor’s holding power. The chain will aid in setting the anchor and keeping it set by lowering the angle of pull, thus helping to absorb the shock of a tossing boat due to wind or sea conditions and reducing chafe due to rocky or shelly bottom.

9. Be Courteous of Other Boaters When Anchoring

If you’re the first or only boat in the anchorage, you’ve got priority. Otherwise, choose your spot carefully so as to allow enough swinging room to stay clear of the others and show your anchoring etiquette . Remember that big boats swing slower and tend to have a bigger arc than smaller ones. Boats with a lot of windage (big canvas enclosures, large cabins, high freeboard and almost all sailboats) will swing faster in high winds.

10. Check reference Points When Anchoring

Be sure to continue to check reference points, and watch to see that your position doesn’t change. Set the boat anchor alarm on your GPS, if yours has one, to alert you if something changes while you’re asleep or occupied. Then break out the sandwiches and enjoy the view.

11. The Windlass is Not a Cleat

The techniques in boat anchoring are the same, with or without a windlass. Keep in mind that a windlass is not a cleat and shouldn’t take the load of your boat under anchor. Neither is it the raw muscle to pull the anchor. Instead, take up the slack as you slowly motor forward to break the anchor free. Secure anchors hauled with windlasses with a trace of line or a chain stop.

5 Tips For Anchoring Your Sailboat

If you are anything like me, anchoring your sailboat in a quite, snug cove or harbor can be hard to beat. But how do you choose an anchoring spot that will provide you with a worry-free “night on the hook”? Follow these five easy tips to enjoy one of sailing’s most sought-after pleasures.

1. Check Your Ground Tackle for Integrity

Check your anchor ground tackle before you make your approach into an anchorage . This applies to quiet coves or crowded anchorages. Ground tackle consists of each part of your anchor , fastenings, rope, and chain that form an “umbilical cord” from your boat to the sea bottom. If one single part of your ground tackle fails, this could put your boat and sailing crew in danger. You could drag anchor and end up aground.

Take the time now to check for chafe (wear and tear), broken fittings, and bent or distorted anchor parts. Pay close attention to the anchor shank (long arm of the anchor attached to your rope or chain). This vulnerable anchor part needs to be straight without distortion. If bent, do not attempt to straighten the shank. This will weaken it–much like bending a paperclip back and forth. Use another anchor for peace of mind.

2. Choose Protection from Wind and Waves

What direction are the winds from right now? Are those winds expected to shift in a new direction over the next 24-48 hours? Answer these two vital questions before you select an anchorage. Next, look at your nautical chart and find a cove or indentation with protection from wind and waves on at least two sides. Protection on three sides gives you the best security.

For example, let’s say the wind blows from the north. You listen to the predicted forecast and winds are expected to shift to the northeast overnight. Choose an anchorage with protection from the north and east, or protection from the west, north and east. That way, your small sailboat will be protected from the present wind and waves (from the north), and the future, predicted wind and waves (from the northeast).

3. Know Your Seabed Bottom Material

Scan the chart inside the cove you have chosen. You need to have bottom material that your anchor can get a bite into. Sand, hard mud, and clay are ideal to drop your hook. Anchors tend to bury deep into these types of seabed materials. On the other hand, rock, grass, or kelp will be quite difficult for most any anchor to bite into. Your anchor might bounce over a rock-hard bottom or slide over slippery seabeds. Take the time to choose an “anchor friendly” seabed and you will sleep better at night.

4. Select the Best Anchor for the Sea Bottom

Carry at least two anchors aboard your boat. Purchase original anchors–not knock-offs. Copy-cat anchors can be of questionable build quality–unable to take the shear loads experienced when anchored. Choose an anchor that works well in good bottoms and one that you can trust in poorer bottoms. For softer seabeds like soft mud or soft sand pick an anchor like the Fortress. For other bottoms, use a well-proven boat anchor like the Rocna.

Cruising sailboats often carry three or more anchors so that they can use multiple anchors in stormy weather. Remember this–your anchor becomes your #1 primary insurance policy underway–not a piece of paper from a marine insurance company! Spend the money for superior anchor gear and you will be rewarded with confidence, peace-of-mind, and worry-free cruising anywhere in the world.

If you are anything like me, anchoring your sailboat in a quite, snug cove or harbor can be hard to beat.

5. Allow for Swing Room and Scope

Survey the anchorage area once you arrive. Make a few loops around the anchorage spot. Look at how other boats are anchored. Follow suite. If other boats have two anchors out, so should you. Favor that side of the anchorage nearer boats with designs close to your boat. Boats of like-designs swing at anchor in similar fashion.

Remember that your anchor marks the center of the circle and you will swing around the anchor in a circle–called a “swing circle”. Estimate the swing-circle of other boats. When you drop anchor, make sure that your swing circle does not intersect the swing-circle of another boat. Keep well clear of shoals (shallow water) or land downwind of your chosen anchor spot. Calculate the amount of anchor rode you need for safety. Allow 7 feet of rode for each foot of water depth–called “scope”. Add expected height of tidal rise and the distance of your bow above water in your calculations.

For example, let’s say you arrive at your anchorage and you will anchor in 10 feet of water. The tide tables say the tide will rise another 5 feet. Your bow is 3 feet above the water. How much scope do you need? Add everything and multiply by 7. 10 feet + 5 feet + 3 feet = 18 feet x 7 = 126 feet. Put out 126 feet of anchor rode for safe anchoring.

Follow these five tips for anchoring your sailboat safe and sound in any anchorage. This will give you confidence and peace-of-mind–wherever in the world you choose to cruise!

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.

Selecting the Right Anchor Size

Holding power increases with weight, but how much is hard to calculate..

Over the years Practical Sailor has conducted dozens of anchor tests, and like many publications, we’ve repeated the common guidance that cruising sailors should buy an anchor that is at least one size larger than what the maker recommends for your size vessel.

During the last two decades, however, the tremendous holding power of some newer generation anchors have caused us to re-think this guidance. Are we paying more for an anchor, rode, and the requisite anchor handling equipment than we need? How accurate are the makers size recommendations? How much insurance are we really getting for the price of a bigger anchor?

For this report we took a range of modern, sometimes called new generation anchors, and their predecessors and averaged their weight vs. vessel size recommendations (see accompanying table). Much to our surprise, the weight recommendations for the new designs, Rocna, Excel, Supreme, etc. are very similar to the weight recommendation for the older, traditional models, CQR, Delta, Bruce etc. In both cases, the recommendation for a 35-foot yacht is approximately a 30-pound anchor. The exceptions are aluminum anchors from Fortress and Spade.

Most of the new generation anchors have been tested to international standards established by the RINA (Registro Italian Naval) or some other internationally recognized society. Rocna, Fortress, Supreme, Excel, Spade have been found to meet standards of Super High Holding Power, SHHP. The older anchors, CQR, Bruce, Delta are rated as High Holding Power. The difference between the two categories is that the SHHP have been tested and found to have a hold, comparing anchors of the same weight, that is two times that of the HHP anchors.

So if we’re getting double the holding power, does that mean we can use an anchor that is half the weight? Not necessarily. Nor can you expect another doubling of holding power by doubling the weight of an SHHP anchor.

Despite the sales pitch that the new anchors have greater holding capacity pound-for-pound, the anchor makers are suggesting that you replace your old CQR with the same weight new anchor. It appears that manufacturers are, in effect, doubling the historic safety factor. And for a cautious sailor, there is nothing wrong with this.

However, consider the advice that is often repeated on internet forums, or the local scuttlebutt, that cruising sailors should increase one size over the makers recommendation. So instead of a 33-pound Rocna for your Tartan 37, you buy a 44-pound Rocna-now with potentially three times the safety factor of an old school anchor. Apart from the added significant expense, this obsession with upsizing – more anchor, more chain, bigger windlass-can also add potentially unnecessary weight and concentrate it in the bow.

So what do we really get with that bigger anchor? There is an idea that if you double weight of an anchor you will double holding power. Except with extra-large commercial anchors and some specific tests, we’ve found no data to support this.

No independent test, as far as we know, has taken a series of different sized anchors of the same design and tested them in the same seabed for ultimate holding capacity. Tests have been conducted on commercial oil rig anchors like the Bruce, and the best scaling is about 90 percent-double weight and you increase hold by 1.8 times.

The only recreational anchor that we are aware of that has undergone some testing to determine the relationship between weight and holding is Fortress (in mud only, see Anchoring in Squishy Bottoms, PS February 2015 ). An analysis of all their tests on a complete range of their anchor sizes suggest that if you triple weight you increase hold by slightly more than two times, approximately an 80 percent efficiency as size is scaled up.

Ultimately, this means that when someone tells you they can calculate the increase in holding power as you move up in size, be careful not to read too much into this conclusion. For one, the ratio used deserves close scrutiny. Surely, the bigger anchor will provide better holding-but how much? This hard to quantify, even with computer modeling. And no matter how accurate your calculation-a ratio based on performance in one type of bottom might not apply in another.

One reason you can’t claim that doubling the weight doubles the holding is that as anchors increase in size, the stress on the construction increases. To compensate for the increase in stress, the steel thicknesses must be increased – and more steel weighs more. So in an anchor whose holding power relies greatly on surface area and how it is distributed, adding more weight doesn’t necessarily result in a commensurate increase in surface area that provides holding power.

And as we’ve shown in our past tests-anchor dimensions (especially the fluke area) and shape can play a significant role in performance. It might be possible to double weight and double the holding power without beefing up the steel, but the resulting anchor would be less strong relative to its designed holding power.

Weaker construction might not matter on an over-engineered anchor. However, we have seen how the use of inferior materials has resulted in anchors that bend more easily at designed loads (see Anchor Tests: Bending More Shanks, PS May 2013 ).

Anchor Angles

In past reports, we’ve discussed in detail how anchor design can impact holding, especially with the new generation anchors ( see An Inquiry into Anchor Angles, PS February 2017 ). As you consider which design best suits your needs, here are some things to consider.

Fluke/shank angle. The fluke/shank angle is the angle between fluke and shank. It is one of the determining factors in how quickly and deeply an anchor sets. For a simple design with flat plate fluke and a straight shank (like a Guardian) the angle is a line down the center of the shank to the hinge and then along the fluke. In shanks with curves or angles, the first line is usually drawn from the shackle pin to the point there the shank meets the fluke.

For three-dimensional flukes (as found in most new generation anchors), you have to estimate where the top of the fluke plate lies. The ballast chamber or shank support that might protrude from the sole, such as with Spade, or Vulcan anchor should not be used to determine shank/fluke angle.

It is the fluke top surface that is important. In previous tests we reported that in thin mud an anchor with a fluke angle of around 45 degrees will outperform an identical anchor with its fluke angle set at 30 degrees. But a firmer sand seabed is entirely different, and research demonstrates the ideal fluke angle for a typical sand bottom is around 30 degrees (see Small Anchor Reset Tests, PS February 2013 ).

Fluke-seabed angle. This is the angle of the fluke to the seabed during the phases of anchoring-most importantly, during the initial penetration into the bottom, and when the anchor is set.

Penetration angle. When an anchor is aligned ready to set, or engage with the seabed (it might need tension on the rode to achieve this) then the fluke will usually be at an angle of 60-70 degrees to the seabed. Commonly the anchor is on its side.

Setting angle. Once the anchor starts to penetrate it will self align and the fluke plate tend quickly toward its setting angle, usually of about 30 degrees. It is coincidence that the fluke/shank angle and setting angle are similar though most anchors tend to show the similarity of the two angles. Center of gravity can have a great effect on penetration angle. This is why many new generation anchors, like the Ultra, have weighted flukes. Having a 30-degree fluke/shank angle is irrelevant if the center of gravity is in the wrong place.

Shank length

If you imagine a Fortress with a shank/fluke angle of 30 degrees but a shank three times longer than its original design, then you can visualize how the anchor will probably simply slide along the seabed when tensioned. The throat opening will be too small. Similarly if you chop the shank in half, the toe of the anchor will simply scrape along the seabed. In both case the anchor will find difficulty in engaging because the penetration angle will be wrong.

Are the makers of new generation anchors over-stating the need for bigger anchors, thus requiring boat owners to pay much more than they might need in order to be secure at anchor? Possibly. Would going with a larger-than-required anchor actually hurt your anchors performance? Unlikely. As is often the case with our anchor reports, it is hard to come with some firm answers regarding both of these questions. Anchor studies are fraught with variables.

In our view, it is no crime to go up one size over the manufacturers recommended size, if your boat and crew can handle it. The anchor may require more reverse throttle to set, but ultimately, it should provide the holding you require. Likewise, it is reasonable to assume that the anchor makers guidance for sizing is reasonable. However, if an online advocate starts telling you that youll get x times more holding power by going up one size, ask him for the data.

Extra weight in an anchor is your insurance policy. Yes, you can almost always get more security with the heavier anchor, but whether or not you will every need that extra holding power is not conclusive. In our view, conservative sizing is added insurance-but until the data is in, we remain skeptical of any absolute claims that attempt to quantify the advantages of more weight when choosing an anchor.

Based on average recommendations from leading anchor makers, the weight savings of upgrading to a second generation anchor doesn’t really pay off until you get into the larger size vessels.

In an anchor whose holding power relies greatly on surface area and how it is distributed, adding more weight doesn’t necessarily result in a commensurate increase in surface area that provides holding power. To compensate for the higher loads, the steel must be thicker, resulting in different surface area/weight ratios.

• As fluke size increases, so do the loads. But if the construction isn’t beefed up to handle the loads, the result is failure. Flat plate steel in this Danforth fluke sheered.
• The shaft of an Excel anchor bent during veer testing.
• The flat flukes of the Bugel anchor makes it easy to calculate the shank-fluke angle.
• Here a Rocna anchor is in the initial setting angle, still capsized on one side, with not enough of its toe is dug into the soil to dig in. Bottom shape and center of gravity (some designs are weighted to control CG), helps to determine this angle.
• This Manson Ray anchor has rolled upright and assumed the angle of penetration that will help the anchor to bury into the bottom.

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.

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.

Welcome to Worry-free Anchoring

When looking for an anchor you want to make sure it digs in the first time, buries deep, has high holding power and holds when winds or currents shift.

For sailboats we have taken every bit of windage, shape and weight distribution into consideration. This all affects how the anchor launches, sets and re-sets.

We have a good range of sailboat anchors to suit all boating adventures, keeping your family safe and ensuring your anchoring experience is stress free.

The right sailboat anchor will depend on the type and size of your sailboat, where you plan to go sailing, and the weather conditions that you expect to encounter. If you are not sure which anchor is right for you, use our simple anchor calculator – link below.

What our customers say about us

David Forester

Mississippi, usa.

I would like to tell you that 25LB Manson Supreme held my 23’ Pro Line Walk around like it was nothing. Where I anchored is a lot of sand, the anchor caught right away and the wind and waves that buffeted the boat around did not budge it. The fluke anchor I have would always slip, and I would have to reset the anchorage. I can safely say this is the best anchor I have ever had. I am so impressed I am looking into a smaller one for my stern (second) anchor.

Graham McKenzie

Wellington, new zealand.

In the 6 & 1/2 years we have travelled more than 45,000 miles, visited 26 countries, and have anchored at least 1000 times. We have yet to use any other anchor than our Manson Plough. It has been totally reliable in thin coral sands, in mud and in the treacherous grasses of the Mediterranean. Most of our cruising friends changed their anchoring tackle after disastrous anchoring experiences in the Med. Many were using locally made anchors. We never needed to consider a new option. The Manson also coped well in areas with strong tidal flow, such as the amazon with it’s 7 knot current. We have had the chain re-galvanized twice in the course of our travels, but the anchor is only just requiring attention. Thanks to you folks at Manson for an anchor that has truly passed the test of time… and distance.

Brian Holloway

New zealand.

We were just starting on our adventure, which turned into the most exciting six month trip I have ever undertaken. We travelled over 4000 nautical miles, completely circumnavigating New Zealand in the wake of Captain Cook. What was interesting in that in the whole of the six months we only spent 15 nights at sea. My aim was to see New Zealand, and we rock hopped visiting everywhere possible, and consequently anchoring most nights. I have a 35lb Manson Supreme holding a 35 foot catamaran, weighing 5 tons. We make a reasonable amount of windage. I felt that a 35lb looked a bit small, but in six months, on very varied types of bottoms there was not one night when we dragged. A marvellous anchor, that I would recommend to anyone.

FLORIDA, USA

Thanks to my Manson Supreme I survived Hurricane Sally in Florida. As winds reached 110mph there was an incredible amount of force at work, but my 80lb Manson Supreme held my Roberts DS440 steel sailboat, while I watched boats around me sink. I was very impressed and grateful. When the winds subsided, we found we had bent shackles and bent rollers, but the anchor was in perfect condition.

Tom McCallum

Auckland, new zealand.

My 15lb Manson Supreme provided a heroic task in holding my 6 ton yacht all night in hurricane conditions in a bay with bad press on its seabed. Needless to say my faith in these anchors is profound and their design and tenacity legendary. I would use no other.

Colin Goldsworthy

We were caught out at Wangaparpara in what I would call a cyclone. It caught us off guard. We had a lee shore, a short scope, in poor holding with only 2 meters under the keel. We had no time to put down a second anchor.

During the next two days we experienced extreme gusts coming off the hills with swell entering the Harbour. That evening there was 95 knots gusts recorded at Channel Island. Our boat is 48 foot, and has plenty of windage. She sails on her anchor. We would sail up, go broadside and then get laid over with the gusts and swell beam on. Your anchor did not budge. The first night I sat and anchor watched, but the second night I was more confident and I slept.

That night many boats dragged their moorings and ended up on the beach. Your Supreme Anchor is great insurance.

NZ Trade and Enterprise

Manson Anchors took a basic component of every boat, and considerably redesigned it to be not only aesthetically pleasing but a real feature on one of the best yachts in the world. This is a real skill and shows again New Zealanders’ ability to create a design that not only solves a problem but does so very eloquently indeed

Brian Bearden

New providence, bahamas.

The Manson Supreme is reliable. Sets quickly, resets quickly, usually no more than the anchors length. Happy in mud, sand, grass. Best anchor we have ever had. Rode out hurricane Joaquin (25 miles west of the eye) anchor didn’t budge in sustained winds of 85 knots. We used this anchor as our main and storm anchor.

Aaron Dixon

I have toured the Manson factory on many occasions and have witnesses first-hand the quality of workmanship in full swing. The attention to detail they take in the selection of the metals, fabrication processes, welding and casting is amazing. Any vessel I own will always be fitted with a Manson Anchor.

Big Angry Fish

The holding power of the Manson Boss will help you stay on that perfect fishing spot regardless of the conditions.

The Manson Anchor will dig in first time so you can get lines over the side straight away.

The sliding shaft is a great feature that makes it so much easier to retrieve the anchor from foul ground.

It is so important for every fisherman to have a good anchor onboard, we recommended the Manson Boss to everyone!

West Marine

The Boss takes the performance of the Supreme and makes it conform to any bow-roller. The Boss works well on power and fishing boats that don’t work with the bow.

The winglets work as a bow-roller to ensure a reliable and quick setting anchor much like the Supreme.

This is an incredibly fast setting, high holding power anchor.

Joe Biden’s new ‘boat anchor’ shoes meant for maximum ‘stability’ as president’s falls spark concern

It’s gotta be the shoes.

President Biden’s new footwear has fed rumors that the 81-year-old incumbent needs  extra stability following a series of falls and stumbles .

Biden has recently been photographed sporting a black pair of Hoka Transport sneakers with his formal suits rather than more traditional dress shoes.

The Hokas are meant for “hiking,” “walking” and “lifestyle” and feature a “quick-toggle lace … designed for easy on and off,” according to the product website — which offers the shoes for between $150 and $200 per pair and also advertises “neutral” stability for wearers who want “a symmetrical bed of cushion.”

The sneakers also boast a seal of approval from the American Podiatric Association as being good for foot health, a benefit which could come in handy for Biden after his recent  physical revealed  he suffers from a “stiffened gait.”

Eagle-eyed observers first noticed the new shoes in late February, about the same time the president received his annual exam.

Social media users have been quick to wonder  if the sneakers were prescribed to  mitigate the president’s several falls .

Biden has especially struggled going up and down the steps of Air Force One, repeatedly slipping and stumbling while ascending to and  descending from his official plane .

After a series of near-pratfalls, the president has opted to use retractable stairs at the back of the plane for boarding — rather than the regular longer steps at the front of the aircraft.

Biden’s slips culminated in an  ugly tumble at the Air Force Academy commencement exercises in June last year, in which he tripped on a sandbag and fell heavily to the stage.

Politico first reported on Biden’s increasing use of tennis shoes back in January, citing a source close to the president who said Biden used to “resist” wearing the casual shoes because he was concerned about not looking presidential enough — but eventually conceded for reasons of comfort.

White House deputy press secretary Andrew Bates claimed Wednesday that Biden uses the active footwear to help him stay fit.

“I know y’all aren’t partial to presidents who exercise, but don’t worry — you’ll get used to it,” Bates told The Post, apparently alluding to former President Donald Trump.

Biden participates in physical therapy to increase his “core stability” at least “four to five times a week,” according to the report from his annual physical.
