Adapting a trailer for a sailbaot

Building a Sailboat Trailer

Since Belle did not come with a trailer, much of why she was so inexpensive, we had to source a trailer to put under her to make her useful to us. Buying a custom trailer was going to be in the $3000 range, 10X what we paid for Belle. Adapting a used trailer was going to be the only affordable. So this is how we set about building a sailboat trailer.

So how does one go about building a sailboat trailer? The easy way is to start with an existing trailer. We need some fairly detailed knowledge about the boat we intend to trailer. We need a trailer that is long enough and strong enough to support the load so we need to know where the center of gravity of the boat is, how far forward and aft the bow and stern are from this point, how much the boat weighs, how far from centerline the reasonably flat/horizontal hull areas extend, and how far these areas are vertically from the bottom of the keel.

Notes taken during survey

Measure It Up

When building a trailer for a sailboat, getting sizes and dimensions right is crucial. I took some critical dimensions during my survey of the boat (yes, I felt comfortable doing my own survey) and while shopping for the trailer. You can see those above. I used these to source my parts for the trailer refit. Our sailboat, an O’Day 23-2 comes in at a max displacement of about 3500lbs. That is equal to the maximum weight of the boat. So I knew I had to find a trailer that could hold 3500lbs. I also knew the shoal keel was going to cause the boat to trailer rather high off the ground and from my father’s experiences I knew I wanted the boat as low as possible and as long a tongue as possible to give us the most flexibility in launch ramp choices. The higher your boat sits on the trailer, the deeper and steeper the ramp you are going to need to launch and recover the boat.

Adapting Trailer for Sailboat

We located our trailer at KM Boat Salvage in Plaistow, NH. Keith had about 30 trailers to choose from. While there were some tandem axle trailers suitable, I decided to go with a heavy single axle Escort brand trailer for a few reasons.

  • A single axle is more maneuverable, less tire drag in tight turns.
  • This trailer was all galvanized and had hydraulic surge brakes (working or not?)
  • The price was half that of the tandem axle trailers ($650)

Looking at the wheels/hubs, I could see they were 6 lugs with 2.5″ caps. And counting the leaf springs, I could see there were 5 leaves. This suggests fairly clearly that the trailer has a ~5000lb class axle. That gives us plenty of room for the weight of the trailer itself once we subtract the weight of the boat. (1500lbs allowance for the weight of the trailer).

Tear It Down, Start With Lights

Once we had the trailer home, we stripped the old bunks and brackets off and removed the broken/old lights. We also removed the bow rest and winch post as they would need to be reconfigured to support the mich higher bow than what the trailer had been set up for.

Building a sailboat trailer

I made up some new light brackets as the old ones had rusted too much. I found some galvanized tie plates at Lowesdepot and bent them at 90 degrees in my bench vise. I then enlarged two of the holes that lined up with the mounting posts from the trailer lights I bought. These brackets are then secured to the frame by pinching them behind the u-bolts for the rearmost bunk brackets.

Building a sailboat trailer

The old wiring was stripped off the trailer and the new wiring from the new light kit was strung out on the frame. Rather than use the wire nuts that came with the kit, I preferred to make the connections more permanent and reliable by soldering the wires together and covering the joints with shrink wrap. You can also dab some dielectric grease over the solder joint before you slide the shrink wrap down for even more protection but its the steel in the cheap nuts that rots rather than the copper wire.

Soldering new trailer wire harness

The ground wire that comes with these kits is always pathetically short. I’ve never had a vehicle with the trailer plug close enough to the tongue to use such a short wire. So, I harvested some white wire from the “car side” harness and soldered it to the trailer harness. I then used some dielectric grease in an attempt to protect the trailer frame from salt (fool’s errand) and a stainless self -drilling screw to bond it.

New Bunks and Brackets for the Trailer

Using the measurements I had taken and the construction of our new trailer, I set about trying to find bunk brackets for adapting the trailer to the sailboat. The dropped axle of the trailer is ideal letting the keel go as low as possible. Measuring up from the keel I needed bunk brackets in the 20-24″ range given we have a 4″ tube section. This tube section, and the lack of horizontal cross members severely limited our choices for off-the-shelf bracketry. Most brackets are designed for 3″X3″ tube cross members. The cross members on the Escort are “L” channel and not suitable for u-bolts. I also refuse to drill new holes in the galvanized trailer frame as these would expose bare steel and rust quickly.

Eastern Marine Trailer Parts Super Store had only one solution for our trailer situation. And I could find no solution elsewhere. The Tiedown 24″ bunk bolster brackets would have to do. However, these are set up to have a swivel top bracket bolted directly to the top with a short bolt. If the brackets were attached to cross members, this would be fine as they would allow the bunks to pivot to the slope of the hull. However, we had to attach to the longitudinal frame members so the bunks would want to pivot forward and back rather than side to side. The solution I came up with was to use bunk stiffening bracket weldments that had a tab welded to a tube. By bolting this to the bunk bracket and using two swivel top brackets to either side of the weldment I could change the pivot direction by 90 degrees.

Building a sailboat trailer

We then had to set about the bunk boards. I had seen a lot of boat trailers with long bunk boards strung between the brackets. It seems to me most of the board area in these cases does nothing but prohibit you from servicing the hull while on the trailer and rubbing bottom paint off. No weight is being carried more than a few inches from the brackets as the boards will simply bend away. I had also seen many trailers using round or square bunks atop the brackets and this seemed more ideal, I originally ordered only four brackets to save money, but once in hand, I realize we had too little margin for error and ordered another two.

Making New bunks

I had to replace the wood on the engine mount as well, so I bought a sheet of 3/4″ hardwood plywood. Did not splurge for marine plywood ($$$$) so it has lots of voids in it. I also wanted to reduce the chances of point contact with the hull. The bunk carpet will only disperse a minute amount of load. I chose to cut 1/8″ luan into “inverse circles” to raise the edges of the bunk pads in hopes that they would spread the load more effectively to the edges of the bunk boards. I laminated two layers of 3/4″ plywood and then the 1/8″ luan, sanded edges round, waterproofed with deck and fence sealer (two wet coats) and then Diana stapled bunk carpet to the bunks with stainless steel staples.

Time to Get the Boat on the Trailer

Trailer ready for boat

With the bunks fitted to the trailer casually, we were ready to go fetch the boat as they would have to be adjusted for height and angle while setting the boat on the trailer in order to complete building a sailboat trailer.

I have a 1970 Coronado 25. I got it last year for the right price (next to nothing). I like the boat but I really do not want to pay for storage over the winter. I put it for sale but no one wants to buy a 25 foot sailboat with no trailer or rack in the the fall (obviously). Unfortunately the marina turned the old rack into firewood. I have a good amount of experience behind a welder and I have some friends who build frames for hot rods and such. It would seem that I could find an old dual axle powerboat trailer and convert it over to use on this boat at a reasonable price. You can find them around here for free or very cheap and I can get my hands on good quality scrap steel that would be good for modifying for free or next to free. This boat is a fixed keel so that complicates things in that, from what I understand the boat will have to be lifted out at a marina. That's not a big problem but it would be nice if that wasn't the case. I have a decent amount of questions on this and their seems to be little information about it. I can find info on people who have done it but not on what their design considerations were. Things I am considering. -Supporting the keel: how much should the keel be supported? -Bunks: I have seen front to back and side to side bunks as well as the pads used for sail boats. What should determine which ones I should use. If pads, how many? Also this will be used to store the boat on over the winter. -How does the weight need to be balanced over the axles. I would assume we want basically the keel centered over the axles maybe a little forward to give it some tongue weight. That seems to be the norm of the ones I have looked at. -Where exactly should i locate the supports. . .is their any exact procedure to follow as far as the locations. To my knowledge sailboats do not have stringers like powerboats so its not like I can shoot for that. -What would my best plan of attack be for the height of the pads to account for the keel height and curve of the hull. It is in the water so measurements will be difficult. . . .let me know of other things I should link into. I am new to this forum and I don't know how much this topic has been discussed so If anyone has good information, links, or knowledge from tackling something like this let me know. I think the trailer is the best option because I have free storage for anything on wheel and It will make the boat more sell-able when that time comes.

Google Road King Trailers and link to the sailboat trailer area of the site. That should give you some ideas on what you might need to do to modify a trailer. I have one for my Com-Pac 23 and it's great. Mine has a guide for the shoal keel and bunks on the sides to support the boat. I think you should stay away from rollers as they don't provide the support that bunk board do and could possibly damage the boat. Also, note the tongue extension. This is a must for ramp launching. I actually only need the rear half of my trailer submerged and I can crank the boat all the way onto the trailer with the winch. As for the keel, it should take most of the weight on the trailer, just like it would if the boat was placed on jackstands in a boat yard. My entire keel sits on the bottom support and is centerd by the keel guides.  

I modded a bass boat trailer, it works fine. If you don't have to go far I would build a cradle for the trailer from wood to get it home then support the boat with slings or blocks to get it positioned right and get to work. Need help? I could use a working vacation!  

how to build a sailboat trailer

Barnacle Bill

Trailer building or modification I have built trailers from scratch and have modified powerboat trailers to accommodate sailboat hulls. First, make sure the powerboat trailer you get has the capacity required to accommodate your boat, with water and fuel in the tanks, outboard and gear. The tires have to be rated accordingly too. Most PB trailers do not have an appropriate keel bed, so that is where you would start. you can weld angle iron in a rectangular pattern on to the thwart members of the trailer down the centerline to that it accommodates a 2x6 or 8 or 10 - whatever seems a good width. The best thing to do would be to lower the boat in slings on to this keel support after you have installed it so that you can determine exactly the location and height of each upright. If you don't have that luxury, or a marina to help, then you have to carefull measure. If you had the old cradle then you could use that as a locator for your fore and aft pads. But, since that ended up in someone's fire place, you either have to find another or start from scratch. Usually your uprights will be welded to the fore and aft members of the trailer, or, perhaps just inside of them attached to a thwart cross member. The location of the cross members will have something to do with the location of the uprights. You can use long boards on each side port and starboard to support the hull, or pads, as you suggested. Pads, if they have threaded rods, like a Brownell boat stand, are adjustable and you can insert them into a square or round tube slightly larger than the threaded rod. Make your tube short enough so you have 6 to 8 inches (whatever works) of adjustment. Depending on the location of the cross members, I would think you would, of course use at least 4 (two in the front and two in the back on each side) as a minimum and maybe 6 if you have a spot to put one in the middle. You can even go 4 on each side, but that might be getting too much for the size boat. With these adjustable pads you have some breathing room if your measurements are suffering some. If you are going to use a board (cheaper approach), then you need to have at least 4 total uprights and possibly 6 or 8. If you can get a perfect measurement (like when the boat is lowered with slings onto the trailer, then you can weld in uprights that are exactly the length you need. Otherwise it might be wise to us an inner and outer tube, whether square or round to adjust. If you are a welder you can drill a hole in the side of the outer tube and weld in a nut to accommodate a bolt which can be used to tighten the inner tube in place. A couple of these nut and bolt arrangements per upright would be better than one. You also need to attach the board with a method that lets it rotate to the right position to sit flat against your hull. You can easily do this by welding a plate with a hole it in to the upper/inner tube so that the plane of that plate runs thwartwise. Then attach an angle iron piece to that with holes in it so that you can screw or bolt it into the board, and also put a bolt through the welded on plate to allow the board to swivel in or out to get the correct angle. The next thing you need to do is probably raise the bow support. The powerboat one will have too short a one and so you have to get creative and add more material (butt weld it in) to raise it so that the winch is in a good place to attach to a bow eye on your stem. The last thing I would consider is keel guides. If you ever were to launch and retrieve your boat - especially retrieve - out of the water, then you want to make sure your keel goes right in the center of the trailer for exact and carefree retrieving. The location of the winch in regards to the bow eye is important to pull the boat up to the perfect towing position. Hope this helps.  

^That is basically exactly what I have been planning in my head so far. Wow great information guys. I wasn't sure how much support their would be for a diy trailer but this seems to be fairly common. I am really excited to get started now. I am definitely going to go with a double axle trailer because they tow so much better and just about any reasonably sized double axle trailer should support the 4,500lbs this boat weighs. I think the bunks are where I am going to go with this. It seems that it will be more cost efficient, provide better support, more capable of being reinforced, and would be easier for use at a ramp. I like the idea of using the bolts threaded in to adjust height and I also like the idea of swiveling bunks. I was basically planning exactly what you described as far as the keel and using guides etc. My dad has big sheets of the plastic that is used on toilet partitions so that would work great to put on above the wood to help the keel slide on easily. This boat doesn't have a bow eye so I am going to have to figure something out with that. Either install one or use kleets. For the measurements I think I will try the coronado forum to ask those guys what their measurements are. My other option is to bring it up to the very lightly sloped shore just until the keel touches at 3.5 feet and the take measurements from the boat to the river bottom. You guys that are using these trailers to launch from a shore, how much draft do you require? With this boat requiring 3.5 feet I will need at least 4.5 feet of depth at the ramp. I am going to get some measurements from the ramps in my area. I'm hoping that it will be doable to ramp this and not have to take it to the marina. Those guys are hurting and they are making prices ridiculous instead of making them less. With this boat being 25 feet long I will basically have 13 feet from right in between the two axles to where the front of the boat will be on the trailer. With that said and taking my depth into consideration where about would a good range be for the length of the tongue. Ie from the front of the boat forward what range of feet should I look for. Just trying to get a feel for what is commonly done. Thanks for all the help so far I think I am getting a pretty good grasp on this!

Before you get to ambitious put together a mterials list including Iron, springs, wheels, tires, bearing buddies, hubs, winch, bunks, etcs. Compare what the raw materials will run as to what factory stock trailer made to fit your boat will cost. You might be surprised as I was when considering building a trailer. I think Coronado was bought out by Catalina? Fair Winds...  

Well I'm not actually building the trailer. I am going to modify a powerboat trailer to fit this boat. Anyone have any experience pulling out a boat with a 3.5 foot draft at a ramp? I went down their yesterday and took some measurements. Based off what I have found, provided I have a long enough trailer, this ramp could definitely accommodate this. It is fairly steep, very deep and has concrete 30 feet out on a low day. I found a section view of the coronado hull/keel and scaled it up with a sketch of the measurements of this ramp. I was having a hard time visualizing the different dimension i would need to account for. based off of this it looks like if i can find a trailer with 18 feet from the hitch to in between the axles and 1 foot of ground clearance to the cross members this will surely work!  

My Com-Pac has only 27 inches of draft and it sits about 15 inches above ground on the trailer so I know it's a bit less than your Coronado. As i stated before, you don't necessarily need the entire trailer submerged in order to get your boat fully on the trailer. The stern will float the whole time and allow you to winch the boat up. As long as the rear end of the bunks or the rear stand pads are submerged enough you should have no problems. If you have thirty feet of ramp at low water you should have no problem. Steep and deep are good too. I have a tongue extension that adds 4 feet of length to the trailer. I have seen some extensions that add more. If you are modifying a trailer this should be one area that you should focus on. It makes launching and retrieving dramatically easier.  

^Thats some good info for me. I was sort of unsure about the dynamics of loading the boat on the trailer, as far as how much of the trailer would need submerged. Like I said earlier I ended up making a cross sectional view of the ramp I use on some graph paper then scaled a cross section of my boat and cut that out. So I was moving the boat around and measuring the clearances out. I had a 17 foot tongue with the hitch a foot from the water and the keel sitting one foot off the road. With those dimensions I was able to get the front of the bunks in the water. Based off what you are saying that should be more than enough clearance. That is great news because the 1 foot of clearance would be a little tricky and I would rather not have to have the rear tires of the tow vehicle in the water. I am focusing on finding something with a low v in the middle and around 18 feet of distance from the tongue to in between the axles. based off what your saying I should have plenty off wiggle room for loading if I can get close to those dimensions. Thanks that is really what I was looking for as I have never seen a sail boat loaded on the ramp before. I've done plenty of power boats just not sailboats.  

I have a retractable tongue, shutup with the comments, on my V25 trailer because in some places you nee to sink the trailer to get the boat off. It slide in and out of the socket with varying positions to lock it in place. Fair winds...

Here's a few before/after pics to wet your appetite for a major DIY project. This was a CB boat so yours will be a couple feet taller. Make no mistake it'll take far more time, effort, brain power and cash than you are figuring but it can be done. If I wasn't hauling it far it'd be best to locate screw jacks at the lift zones and a bow roller with a stop and a stout bow eye/hook. Otherwise build bunks to saddle the curves exactly so you don't have hot spots wearing away while you truck it down the road. You're sure the boat is worth the effort, right? Good luck. Mike

Keel guides are definitely a good idea (as per the centerboard boat trailer photos). Rollers are easier than bunks for launch / retrieval, but apply more force to the hull. Keep the structure of the boat in mind when locating rollers / bunk supports so that the bulkheads take the load as much as possible. Be sure to have a platform under the keel as for a keelboat the keel will take most of the weight.  

You don't want to use cleats for a couple of reasons. First you most likely will tear them out of your deck and secondly they will be in the wrong location. A properly placed bow eye will put the boat right where you want it when retrieving the vessel out with the use of the winch.

I'd cut my loss and donate it to the local youth sailing group immediately. You'll feel better about helping an enthusiastic group with deeper pockets and plenty of volunteer help. Your time is worth something, added to your cash outlay it sounds like a break even trial to still end up with a boat that you'll inevitably have to deal with next spring again. Let it go...life is too short to mess with a beater boat you don't absolutely love. Mike  

I bought a trailer yesterday. I really couldn't find any tandem axle trailers for under 400. The single axles are everywhere and crazy cheap but bigger tandems start getting expensive! I ended up heading over to a marine salvage yard 30 min from my house to see what they had. With 500 junk boats their they had a very good selection of old trailers for cheap. I made a deposit on a tandem axle trailer that has a 24 foot powerboat on it. If anything this will be to big. . .not a problem! From in between the axles to the tongue is 21 feet so it will easily launch the boat from the ramp. He is charging me $400 for it which i thought was a good deal. They just have to scrap and move the boat that is on it before I can go pick it up. I should be starting this project pretty soon! I have about $700 into this and I will have about $1200 once it is on the trailer. I am sure I can get it sold in the spring and not lose anything. I don;t have to pay anything for storage and I can keep it their as long as I want so It is not costing me any money to not sell it. I would think I have deeper pockets than any local sailing organization I just want to be able to get out what I have in the boat. I love fabricating so I will enjoy this project and hopefully I will be able to sell this boat in the spring. Plus after spring I will have some very fat checks heading my way so I will be more likely to buy another sailboat that I can actually keep at my dock.  

So i got the trailer built this weekend and gave it a test. I'll summarize To modify the trailer I used a section of old scaffold which basically emulated to the t what the boat jacks do. same material and everything. Tripod with a vertical tube and adjustable pads. For the keel support i got a set of pallet rack cross members which were rated at 5k lbs. everything was very solid. So we pulled the boat out. Ramp worked out great and the truck had no problem. The boat practically floated on. We pulled it out and had to adjust the pads a couple times. Once we got it pulled out we then realized that it was sitting a good two feet to far back. negative tongue weight and the trailer was deflecting as a result. So We were going to back it in and re adjust but my dad and i had a mutual feeling of terror looking at that huge boat up in the air like that. It was getting late so we backed the boat back in and called it quits. I am really scared of trailering that thing it is just so big and high. There were some things with the design that I don't like. I separated my pads by about 11 feet centered over the axles.I just put them on the cross members. That was to far and I think the load would be more steady if i move those closer to the axles. I am a little concerned with the weight. The trailer had a 24 foot powerboat on it so i think weight would be comparable. However with my boat on their the suspension seemed to be bottomed out. The tires are good for 6k lbs though. Is this crazy? I am starting to contemplate just taking this to a marina and using my trailer as a rack. It just seems so terrifying to trailer a sail boat of that size on the road the boat is so tall. Just looking up and seeing the rub rail way up at the top of my reach is scary. I try to tell myself that the weight is all way down low on the keel but it still seems creepy. I am not concerned with my supports and welds. That is all very capable of supporting the applied loads. What scares me is the trailer itself failing at some point. with a 25 foot trailer and that much weight an uneven load can cause some crazy bending moments.

How to build a sailboat trailer extension

how to build a sailboat trailer

This is the remarkable true story about how I built a sturdy trailer extension and got 27 stitches in the process. I recommend the  former, though I included instructions on how I got the latter just in case you’re interested.

The previous owner of my Catalina 270 took her in and out of the water with a crane. Unfortunately on my lake, there are no cranes, so we have to launch the boat by backing the trailer into the lake. When the lake is low or the ramps shallow, it is necessary to extend the trailer out further into the water than the tow vehicle can go.  One way to accomplish this task is by building an extension to go between the trailer and tow vehicle, which allows the trailer to be let down further out into the water.

On my prior boat, I used a strap and rolling wheel on the front of the trailer to lower the boat in. The problem with the strap (or rope, or cable) method is that you can’t push the trailer further into the water. Often times there are large ruts or pits in the dirt beneath the ramp caused by power boaters gunning their engines to push boats on and off trailers. To pass over these ruts using a strap, you have to let the boat back quickly down the ramp to build up enough momentum to roll through the ruts, and I always worried that a deep rut on one side or the other would tip the trailer to the side. It never did, but I always imagined it happening.

So this time I wanted more control over the boat, and decided to build a solid bar extension. I looked at several designs on various websites and decided I wanted one that was heavy duty enough to support the weight without needing a dolly wheel under the front of the trailer. I wanted about 15 feet of extension, and it needed to be easily installed, removed, and stowed on the trailer.

how to build a sailboat trailer

First, off to the local metal shop, where I purchased 15 feet of galvanized steel, in the same dimension as the steel on the trailer’s tongue (3″x5″). I think it’s possible to go with something smaller, but not knowing how it would handle the load I decided to stay with the original dimensions.

Next, I ordered a 2-5/8″ hitch coupler from Amazon on the front of the hitch extension, which would connect to the tow vehicle’s ball without having to switch ball sizes.

how to build a sailboat trailer

Then, I had the terrible idea of simply bolting the hitch extension alongside the trailer’s tongue. Two large bolts, spaced about 2 feet apart, seemed like they would do the trick. However, the weight of the trailer bent the bolts and the extension sagged to about 2 inches off the ground. It was enough to launch it the first year, but I knew I’d need a sturdier connection between extension bar and trailer by the time we hauled out in fall.

I ordered a 2- 5/8″ trailer ball to mount on the top of the extension bar. This ball would lock into the trailer hitch. At the back end of the bar, I planned to have two bars welded on that would hug the sides of the trailer tongue and be secured on top with a hitch pin.

The bars I chose were half inch thick steel. This is how I ended up with 27 stitches. My battery powered drill would never make it through, so I ran to the hardware store to pick up a corded drill. The drill I’d planned to buy was good, but when I got there I found a higher amperage drill on sale for less. More power for less money? Yes, please. So I walked out of the store with a 9 amp Hitachi drill.

how to build a sailboat trailer

I lifted my 25 lbs vice off the workbench and set it on the garage floor for safety. I locked the steel in the vice and started drilling, stopping every 30 seconds or so to add some oil into the hole. The whole operation felt pretty safe until the drillbit punched through the back side of the steel. That’s when the full fury of all 9 amps was unleashed. That monster drill grabbed the steel bar and 25 pound vice and spun them in circles so fast that by the time I let go of the trigger it had spun around 2 full times. I felt something had hit the back of my leg, and glancing down, realized I was in trouble. The half inch bar traveling at 9 amps had laid open the back of my calf. It was going to need stitches. And not a few, because as it turns out, half inch steel is not a very precise cutting implement.

On the drive over to the hospital, I used Intermountain Healthcare’s “ConnectCare” telehealth app on my phone. It was amazing, I could actually show the doctor a video of the wound from the car so she could tell me if I needed to go straight to the emergency department, or just a clinic. One emergency department visit and 27 stitches later, I was good to go. And I only had one more bar to drill through. It took me two weeks to get the courage to do it.

how to build a sailboat trailer

But the end result was a great trailer extension. It’s very sturdy, able to hold the front of the trailer at the same height over the full length of the bar. It also has enough ground clearance that I can attach it on flat pavement and drive it over the edge of the road onto the ramp without bottoming out. This makes work on the ramp much safer, because the trailer is never unhitched from the tow vehicle while on the incline. I also have an impressive scar on the back of my leg which I refer to proudly as “a sailing injury.”

The first step in building a boat trailer is to design it. Designing your boat trailer involves determining the size and weight capacity of your trailer, choosing the type of material you want to use, and creating a plan for your trailer.

Determine the Size and Weight Capacity of Your Boat Trailer

The size and weight capacity of your boat trailer depend on the size and weight of your boat. You need to measure the length, width, height, and weight of your boat accurately before designing your trailer. You can use a tape measure, a scale, or a calculator to do this.

The length of your boat trailer should be slightly longer than the length of your boat, to allow some space for the hitch and the winch. The width of your boat trailer should be slightly wider than the width of your boat, to allow some clearance for the wheels and tires. The height of your boat trailer should be as low as possible, to reduce wind resistance and improve stability.

The weight capacity of your boat trailer should be greater than the weight of your boat, plus any additional load that you might carry on your trailer, such as fuel, water, equipment, etc. You can use this formula to calculate the weight capacity of your boat trailer:

WeightCapacity=BoatWeight+AdditionalLoad+SafetyFactor

The safety factor is a percentage that accounts for any possible variations or errors in your measurements or calculations. You can use a safety factor of 10% to 20%, depending on how confident you are in your data.

For example, if your boat weighs 1,000 pounds and you plan to carry 200 pounds of additional load on your trailer, you can use a safety factor of 15% and calculate the weight capacity of your boat trailer as follows:

WeightCapacity=1,000+200+(1,000+200)×0.15

WeightCapacity=1,380pounds

Choose the Type of Material You Want to Use

The type of material you want to use for your boat trailer depends on your budget, preference, and availability. You can use wood, metal, plastic, or a combination of these materials for different parts of your trailer.

Build Small Boat Trailer

  • 28 August 2017

TO BUILD A SIMPLE trailer for a small light, runabout of 10ft to 13 ft long by about 5ft wide (3-4 metres long by up to 1.5 metres wide) this design is ideal. It is suitable for a dinghy, tinny, Parkercraft or even your children’s yacht. You can adapt this economical design, but componentry is not cheap, so keep it simple if you want it to remain as affordable as possible.

Build this small boat trailer for summer

TO BUILD A SIMPLE trailer for a small light, runabout of 10ft to 13 ft long by about 5ft wide (3-4 metres long by up to 1.5 metres wide) this design is ideal. It is suitable for a dinghy, tinny, Parkercraft or even your children’s yacht. You can adapt this economical design, but componentry is not cheap, so keep it simple if you want it to remain as affordable as possible. Don’t go over the top. The boat sits on keel rollers on the main beam drawbar, and above the mudguards. It is supported by chine rollers at the back, and is very secure when strapped down. The frame which holds the chine rollers and supports the axle, springs and wheels, is secured to the main beam by U-bolts, and can be shifted between two keel rollers to adjust for the different sizes of boat. The winch post at the front is also fi xed to the beam by U-bolts and can be adjusted for the position of the boat bow. I imagine a boat having an overhang at the back of 200mm or 300mm – the exact distance doesn’t matter. The trailer will run easily from bach to beach. When you want to travel on the road, the rear lights number plate and Warrant of Fitness sticker can be placed on a light board strapped to the back of the boat. That’s the best way to keep the construction simple. Otherwise you have to fi x lights on metal arms on either side at the back, and that can limit the width of the boat you can get in. The material is all steel, although the construction is plain and, in total, not too heavy. The cross members are made of 50x50mm angle iron, and the side rails of the frame are 40x40mm RHS. The mudguards are welded directly onto the side rails. The axle is made of 40x40mm RHS. The main beam / drawbar is 50x50mm RHS of 5mm thick steel – you don’t want the bar bending because at 3.6 metres it is fairly long. Following normal practice, I tack-weld the parts fi rst, moving through the whole trailer to ensure that it is all square and all the measurements agree. When the trailer has been fi nished and assembled I do a full weld on everything I tack-welded. The components that I can dismantle, I take to the bench to weld

Wheels and hub seats

You could use standard hubs or other, different hubs, but I’ve used marinised hubs that include a rubber seal in the kit to stop water getting in. Rubber is better for boat trailers because of the contact with water. This arrangement is better than a lip seal, because the water pressure comes on the rubber seal and closes it effectively. You could go to wheelbarrow hubs and wheels if you want to – the boat the trailer will carry is fairly light. The smaller wheels would be good enough, and would be okay if you were going only from bach to beach, or not very far. If you want to travel on a public road you have to get it warranted, of course. The way I have built this design is up to warrant standard.

The springs come with three leaves, for a 750kg rating, but I have taken one leaf off because I feel that the springs are too heavy. As a twoleaf spring, it could be described as a 500kg rating, and that’s plenty for a boat where its fi xed weight is known. Ordinary domestic trailers need stronger springs as they can carry all sorts of different weights. If some people want to load the boat up with gear when towing it for the holidays, they might like to keep on all the leaves that come with the springs as standard kit.

Begin with the 3.6 metre beam which is the support for the whole trailer and the drawbar. Pre-drill a hole in the end of the 50x50mm RHS for the safety chain to be bolted into the drawbar, not welded. Mark the holes through the coupling onto a 220mm-long piece of 80x10mm flat steel and tack-weld this coupling plate onto one end of the drawbar. I have the coupling plate sticking about 80mm out from the front of the bar, but you could have as much as you like, provided there’s enough clearance for the nuts holding the coupling on. Square up the coupling plate which is tack-welded. Then put the main beam on two jacks or similar supports so that you can work on the frame. With the frame on the main drawbar or beam, I can get the measurements correct all round for frame, axle and springs.

Mark the 1200mm-long angleiron cross-members at the centre. Square up the angle iron on the main bar. Mark and then drill holes on either side of the centre point to fi t the U-bolts which will clamp the front and back angle iron pieces on either side of the 50mm drawbar. The back angle iron then has four holes drilled on either side of the main drawbar for the chine rollers. The extra holes allow the chine roller assembly to be moved to suit different boat hulls. Measure 50mm in from each end of the angle iron, and then mark the holes using the fi xing plate which comes as a kit with the chine support roller assembly. This is a U-fi xture on a long bar that is clamped by the plates through the holes in the angle iron. The distance between the front and back cross-members in the frame is determined by the length of the springs. In this trailer, the measurement is 680mm length from front spring hanger to back slipper. It’s not important what measurement it is, but what is measured is whatever the springs are for the frame. The RHS is placed in-between the angle iron cross-members to hold the angle iron in place. I move the RHS out 20mm or so sideways away from the mounting brackets for the mudguard. It also takes the RHS away from the chine holes. Check the frame for square. Clamp it and tackweld the frame. I put the frame on the bench to tack weld the slippers and springs on. Put the frame back onto the main bar and prepare the axle.

I found it was 1195mm. I added 20mm each side for the clearance to the wheel. The total was 1235mm, so I cut the steel for the axle at that length. Get the centre at 617mm (half of 1235). Use this to measure back for the holes drilled in the RHS for the locator pins, which are in the centre of the springs. The distance between these locator pins is 1155mm. Half is 577mm, so the locator holes in the axle will be drilled in the axle at 577mm out from the centre at 617mm. Measure 577mm and check the chalk marks against the spring locator studs. Don’t do as I do, and measure incorrectly. Fortunately, the holes I drilled in the wrong place in the axle could be used for the weld which is melted into the stub axle. Drill 16mm holes in axle at the spot markedfor the spring locators. I used the holes I drilled incorrectly first, to fill with weld to hold the stub axle. Otherwise I would have filled those holes in. That’s the beauty of steel – – you can fill in if it goes wrong, but you can’t do that with timber. The axle is being put under the springs this time (rather than on top as with the previous trailer). That’s because there’s very little clearance between the axle and the main bar. When the weight goes on and the axle moves up with the springs, it would hit the towbar. With the axle underneath, there’s not that problem (the axle is bolted on with U bolts). Assemble the wheel and hubs temporarily according to the kit instructions, and check that the clearance between edge of the frame and tyre is correct—20mm. Also, check that the mudguard is in the correct place by holding it over the wheel at this point. You don’t want the wheel sticking out beyond the mudguard. Now I weld the stub axle into the RHS axle. Push the stub axle in and hold it square. Weld the plug in the axle hole to hold the stub axle in. I ordered the stub axles specifi cally for the 40x40mm RHS and Trail Com turned the stub diameter down so it fits easily and squarely into the RHS. Because I have taken one leaf off the spring, the bolt through the leaves is now too long. I cut off the extra thread on the top of the spring with a cutting wheel. I also have to drill down into the stub axle where the spring locator hole is to make it fit where the bolt is longer under the spring (that’s where I have taken off the leaf). This allows the axle to sit down properly on the spring locator. If you leave the three leaves in place for the 750kg spring weight, there’s no need for this adjustment. I place the axle on the spring locator studs under the springs and bolt it in place to the plate above the spring with 40mm U-bolts.

Put the wheel back on temporarily to position the mudguards. I place a block of wood with a 70mm clearance above the tyres to get the height of mudguard I want. That looks better than 50mm clearance which would also be possible. Simply weld the mudguard directly to the side rail of the frame.

Put the solid-rubber keel rollers along the main bar about a metre apart, with the fi rst roller welded to the very back of the drawbar. The trolley frame can move and should be towards the back. The weight of the boat is toward the back with something like an outboard motor. The distance that the frame can be adjusted is the distance between the rollers. With the boat overhang at the back by about 200mm or 300mm, the bow would probably reach over the third roller, and three should be enough.The chine rollers bolted to the back angle-iron cross-member of the frame help with pulling the boat on and off the trailer. A drawbar skid welded to the bottom of the drawbar at the front stops the coupling plate digging into the ground when the trailer is empty and dropped forward.

From your own boat, measure the height of the eyelet on the bow post. You need to position the hook on the winch wire at about this height so you will have a reasonably straight pull when winching the boat on to the trailer. The winch post is made of 35x35mm RHS welded to a plate which is U-bolted to the drawbar. This means the winch post can be adjusted back and forwards depending on the size of the boat. I calculate the height of the winch post from the total distance from the drawbar to the eye on the bow of the boat. In the case of the boat for which I’m making this trailer, the eye is at 480mm, so I want the wire from the winch to come out at about that point. With the winch 80mm high, I need a winch post of 400mm. I cut the 35x35mm RHS steel at 390mm to allow for the 10mm plate welded onto the top where the winch is bolted. I lean the post, cutting it to sit at an angle of 80 degrees, then weld it to a piece of 5mm or 10mm plate. This is U-bolted in position, so can be adjusted. For a heavier boat on a bigger boat trailer, I would normally weld a supportive backstay onto another plate U-bolted to the draw bar. This backstay would be welded to the winch post. But the winch post doesn’t need extra support on this smaller trailer. On top of the winch post, I need to weld a fl at plate 80x10mm thick and 100mm long. The winch is bolted to this plate. I could get away with a 5mm thick plate. Before welding the plate on, using the winch I mark the bolt holes for the winch itself. The winch can always then be unbolted if it breaks and needs to be repaired or replaced. I am using a small 1:1 ratio winch. This is about the right size for a small boat, but they come in different sizes and ratios for heavier boats (from 3:1 to 15:1). Onto the winch post, I now weld a 200mm RHS stalk at an angle of 70 degrees up. The solid rubber bow block is bolted to this, so the bow of the boat can be pulled into the bow stop. With your boat present, you can always measure where the bow will stop. The metal plate to which the bow block is bolted is welded to the end of the stalk.

Handle and tie-ons

To make a handle for lifting and pulling the trailer, I weld a 300mm length of 35mm-diameter pipe across the drawbar just behind the coupling plate. Onto the stalk, I weld a small loop for attaching the boat to. I made this by hacksawing out a link from a little piece of safety chain I had spare. Never throw anything away or discard scraps and spare bits of metal – they come in useful some time. The last thing is to weld tieons of bent 8mm rod to the front and back of the frame. I then dismantled the trailer to be sent for galvanizing. Be sure that you have drilled holes in the closed RHS sections – the winch post, winch stalk and axle – before the trailer parts go for galvanizing. The main beam / drawbar has been left open at the end, and the two RHS side rails on the frame are also open at the ends, so that the galvanizing can penetrate.

Metal spinning lives

The exact origins of metal spinning are unknown but the craft can be dated back to ancient Egypt where examples of spun vessels have been found. Metal spinning today differs little from the past with the only real advance being that an electric motor is used to drive the chuck instead of manpower or water power. Before the advent of power presses, metal spinning was used to make almost all round sheet metal objects such as pots, pans, lampshades and wheel rims. The principle of metal spinning is simple: a disc of metal is clamped between the tailstock and a former or mandrel. The disc is spun and the operator then uses a lever to manually work the metal down onto the mandrel. The process helps maintain the structure of the material and does not stress it, resulting in a stronger and more stable product than if it was pressed. While metal spinning by hand does not generally alter the thickness of the material, hydraulic-powered tools can be used to flow-form products making sections thinner where required.

Rolling stool build

My wife, Rosaleen, loves to cook, and will happily spend an afternoon in the kitchen cooking meals to be frozen and given to our daughters and their friends whenever the need arises or opportunity presents. However, arthritis makes standing in one position for long periods difficult for her. She wanted a stool for the kitchen, but ours is a galley-style layout and quite narrow. It’s wide enough for one person to walk past another working in the space, but the presence of a stool would present a major obstacle. “Why don’t you invent something?” she said. I love a challenge like that.

‍ Key Takeaways

  • There are many sailboats that anyone can build from home depending on tastes
  • Budget will be the biggest deciding factor on a majority of the process
  • Consider kits that come with most of what you need or choose ones that are all-inclusive
  • Design complexities and new materials may make the building time process longer
  • Plan the best you can ahead of time to save money and your working hours

‍ Buying a sailboat can be expensive, but building your own can save you money. So what are sailboats you can build from home?

Sailboats that you can build from home will likely be a small boat under 20 feet. These could be from many different boat suppliers such as B&B Yachts, Brooks Boat Designs, and Chase Small Craft. Boat plans will vary based on your budget and how much time you have on your hands.

Based on my previous experience, building your own boat will take much longer than if a professional were to do it. You also have to be able to study plans, consider various sailboat designs, and have tons of supplies such as fiberglass tape or fiberglass cloth. On top of that, you will also have to be good with your hands.

‍ Top 10 Affordable Sailboats Anyone Can Build at Home

Building your own pocket cruiser or other styles from boat plans is an impressive feat, as this will need dedicated time and money to assure your boat sails safely. Boat building takes a lot of patience as well, especially since this will not be completed in a fast manner.

Finding boat plans and materials that fit your budget will be key to being able to complete the project. The time it takes to complete these projects will vary on your overall experience and needs. Below are 10 of the most affordable sailboats that you can build in the comfort of your home.

B&B Yachts

B&B Yacht

B&B Yachts have 14 different boat plans you can choose from to find the boat of your desires. Their shop is located along the Bay River in North Carolina where they construct all of the kits and have a 100 foot dock to show off your project once you complete it.

One popular model to check out is their Core Sound 15, as it is the perfect size for those wanting to build a modest size boat for a handful of people on board. Their website features some videos of completed projects and the plans or kits for purchase.

  • 14 different models to choose from plus some dinghies
  • Various monohull and multihull options
  • Friendly customer service with attractive prices
  • Might be too many options for some that are indecisive
  • Not ideal for those wanting to have a motor sailer

How Much Does it Cost to Build a Sailboat at Home?

As you have likely already done so, the math between building your own boat and buying one may be a huge difference. Likewise, you may even enjoy the challenge of taking an older boat that is gutted and restoring with parts from a kit to build one new again.

But how much does it cost exactly to build a boat from the comfort of your own garage or workshop? The prices are going to vary dramatically depending on your situation and material needed to get the job done. In addition, the time that it takes to complete this will also vary.

Sail plans are rather inexpensive if you are aiming to build a small boat. These plans allow you to see the workings of the boat design and what you need to build the boat.

Without these plans, you will not know the exact details of the design and it can cause major issues with the boat’s hull or other areas of the boat. Think of these as the backbone or instructions of the boat’s infancy before being built.

Price Per Square Foot

You should assume to pay anywhere between $300 to $600 per square foot if you are interested in building a boat. Buying a kit outright can be a good way to save time, but oftentimes these do not come with everything you need.

Instead, you should try to source as much of the materials at the best price as possible. Thinking ahead is part of the process and you might be able to score a deal at a lumber yard or hardware store for parts.

Boat Designs Matter

The design of the boat will be much different from one boat to the next, regardless if they are the same size in length. If you are pondering boats that range anywhere between 16 and 20 feet, you should factor in the shape of the hull, any rigging, and various appendages.

Prices tend to increase when there are more complexities within the designs. If you are considering a kit with more details than others, you will also have to pay more for the designs on that as well.

Kits Can Differ

It is important to understand that all kits are not going to be the same. As you gander at sailboat kits online to stitch together, you need to thoroughly look over to see if you have everything you need before buying.

It would also be at your advantage to ask the seller if any additional parts or supplies are needed. This may change your dynamic on the kit buying process and you may pass up one for another if it has everything you need. An all-inclusive kit may cost several hundred, if not thousands, of dollars more to have the convenience of everything in the bundle.

Construction Approaches

Some boat plans may require you to have certain tools to get the job done. This means special saws or planers, which the average person simply does not have.

Purchasing specialty tools might be expensive upfront and hard to find depending on what it is. Your best bet would be to check locally for others trying to sell their tools or consider a boat plan that does not require extensive tools to finish the job.

How Long Does it Take to Build a Sailboat?

An easy to build sailboat could take a while to build from scratch. Many different variances come into play that are difficult to pinpoint for everyone. But how long is that exactly and how will your experience play into this?

A fun project to sail in the wind could take you several months to well over a year depending on the boat plan and how big your boat is going to be. In addition, the materials all need to be accounted for prior to starting in the event a hardware store does not have them in stock.

Time Varies

The time that passes for simple boat designs on small sailing vessels can be done in a few weeks. This is assuming you have everything you need and work non-stop around the clock.

Certain complex situations may make the process long, such as the difficulty of working with some materials. If you are a skilled laborer, it may take you half the time compared to a novice. The amount of time it can take will vary on your availability and skill level.

Planning ahead will undoubtedly offer the most time-saving features. It also helps if you can tackle parts of the project at your own pace.

Complexity of Design

The design of the boat may make the construction process longer. For example, it may take you longer to build a catamaran compared to a similar lengthed monohull.

More complex designs might require more materials, therefore making the process a bit longer to complete. Furthermore, you will also need more experience working with difficult designs and that will affect you more as a newbie.

Be sure to manage your expectations well and do not allow yourself to become too stressed over this fun project. If you can, seek expert boat building advice from a local builder or the company you purchased sail plans through.

Quality Materials

The quality of the materials will matter significantly when building a boat and will greatly affect the time it takes to construct it. Handling fiberglass or carbon fiber might require specialty tools, while wood also demands a certain level of craftsmanship.

If you are not skilled at working with the material at hand, it might affect the quality of the build and you may have to go back to fix mistakes. This will definitely add more time to your project, because mistakes are bound to happen with your first project.

To save time, consider adding the tools and materials throughout the year or as often as your budget allows. You may want to try testing your skills on fiberglass or other materials to get a feel for how to work with it.

How To Make Boat Trailer Guides

Jack K. Pride

  • BOAT TRAILER

You’re at the boat ramp, excited to launch your boat for a day out on the water. But as you begin to reverse down the ramp, visibility becomes a challenge, making it difficult to align your trailer properly.

Frustrating, right? That’s where boat trailer guides come to the rescue. These simple yet effective markers can make loading and unloading your boat a breeze. So, how can you make your own boat trailer guides?

To start, gather the necessary tools and materials for the project. Take precise measurements of your boat and trailer to determine the optimal guide height and position.

Next, cut the PVC pipes or steel angles to your desired size, ensuring they provide adequate guidance for your boat. Mark the points where you’ll insert bolts to secure the guides to the trailer. Proper alignment is crucial for stability and safety.

As we delve deeper, we’ll explore additional steps and tips to help you create custom boat trailer guides that perfectly suit your needs. So, let’s get started on this DIY project.

Note: Are You Looking For?
  • Can You Rent A Boat Trailer?
  • How To Center A Boat On A Trailer

How to Make Boat Trailer Guides:

There are multiple ways you can make your boat trailer guide. We will talk about at least two of them. The first one is PVC (DIY) made trailer guide. The second one is setting up an online brought guide, the way you should prepare the guides.

How to Make PVC Boat Trailer Guides ?

Making your own boat trailer guides using PVC is super easy and fun. It will take only around 30-40 minutes to complete. Here is how you do it-

Things You Will Need:

  • 2 Pieces of PVC.
  • Drill Machine.
  • Washer Locks.
  • Tape Measure.
  • Marker Pen.
  • Hand Saw Machine.
  • Small Wood Pieces for Bunking.
  • Post-Light Kit (Not Mandatory)

Take the Boat and Trailer Measurement:

The first thing you will need to do is taking the actual measurement on-how big will be your trailer guides. A usual middle type boat and trailer should be covered with around 5 feet or a little longer. However, it’ll vary depending on your boat and trailer height.

Cut the PVC as Your Required Size:

Then, use the hand saw to cut down the PVCs according to your requirement. For me, I always keep some extra length for safety. If I made any mistakes, then it is easy to cover with the extra distance. But it is not the best choice for all the time.

Mark the Bolt Insert Points:

Next, use the measuring tape to pinpoint the bolt insert points on the PVC. I also use the bolt itself to prevent from making any mistakes. Choose the point by leaving some PVC below the bolt joint. For me, I left around 5 inches for the first hole.

Also, your bolts can be either U-shape or middle V-shape. So, it’s better to use the bolt itself to identify the hole points. Then, use the marker pen to mark the hole points that needed to be drilled.

Use the Drill to Create Holes on PVC:

Use The Drill To Create Holes On PVC

After that, it’s time for some drilling. I love to drill, LOL. Sorry for the unnecessary talk. Use the drill machine to create holes in your marking points. You have to be a little careful here.

The holes are two ended. So, make sure they are in the middle. Also, if you are planning to use trailer guide lights, make holes for their setup too.

Set The Light on PVCs (Not Mandatory):

If you drive with your boat during the night or load and unload during the night, you will need a post guide. Boat trailer guide lights will help you to avoid any mistakes or accidents during the night.

Personally, for me, I prefer light always because I happen to drive with my boat after sundown a lot.

Here’s our recommended light you can use. This one is submersible. So, it happens to be accidentally your trailer goes into the water, it won’t hurt your light. Also, it is very easy to setup.

Put the PVC Cap:

Use your PVC cap to cover the ends. Normally covering the upside should be enough. But having cover even below can prevent the inside of PVC from getting all muddy and dusty.

I recommend using them on both ends. It is straightforward to clean and wash-off with them on.After completing all the initial steps,your boat trailer should look like this.

put the PVC cap

Place the PVC on the Trailer:

Now, you have to set the PVCs on the trailer rod. After setting the PVC and bolt, use the washer and nuts to tighten up. Remember to keep them a little loose. Keep some extra length below the trailer rod.

PLace the PVC on Trailer

Before going to the next step, check again everything is alright or needs some adjustment. If required, perform those.

Use the Wood Pieces as Bunk:

The small wood pieces put them in between the boat trailer rod. Why you need them? Whenever you are using the trailer to load-unload your boat, it may create pressure directly on the bolts and PVC.

Use Wood Pieces as Bunk

At least a 4-5 inches gap is required between the boat and the trailer guide. These wood bunks will help you to create that gap and also will work as support

Online Bought Trailer Guides:

Setting up an online bought boat trailer guide is easy and simple. Follow their instructions, which come with the product. If you’re not up to making one for yourself by using PVC, you can always have one from the local store or online.

For your convenience, we have provided the products which we think are the best in the market.

This one is very sturdy and solid looking. And also one of the best in the market. However, it doesn’t have pre-installed light with it. So, if you want a light too, you have to purchase one. You can use our recommended light or can pick one by yourself. This one another good choice if you are looking for boat trailer guides with pre-installed light.

Frequently Asked Questions

Do boat trailer guides work.

Of course, they do. A boat trailer helps you to prevent from damaging your boat’s bottom. Having them makes it easy to load and unload during the day or night.

If you are driving with the boat trailer during the night, the trailer guide with lights can help you prevent any accident.So, it is a very useful and supportive kit for a boat owner.

How tall should boat trailer guides be?

It depends on your boat size and preference. According to the experts and for me, boat trailer guides should have enough length which can be easily visible from the driving seat.

And also, you can keep track during the loading and unloading process. Mine is 5.5 inches tall. So, just pick your size according to your requirement.

Final Thought:

After reading this article, now you should know- how to make boat trailer guides using PVC. You can setup trailer guide lights for further improvement. Both are helpful and become necessary sometimes.

Try to make yourself with PVC or wood pieces or anything you prefer to work with if you can’t complete the process. Then, you can go for online or offline purchases.

You can always use our well researched recommended products or choose one by yourself. Well, that’s all folk for today. Until the next time, stay healthy and safe and happy outing.

How to Load a Boat on a Trailer.

How to Load a Boat on a Trailer (Retrieving Your Boat)

how to build a sailboat trailer

Table of Contents

You and your crew had a day of fun and adventure on the water, you’re nearing the dock, and it’s time to load your boat back onto its trailer. Also known as “retrieving the boat” in nautical jargon, loading a boat on its trailer can be smooth and easy.

Here are 10 basic steps for loading a boat on a trailer:

  • Drop the tow vehicle driver and passengers off at the dock.
  • Ensure you’re out of the way of the launch area while you wait for your tow—if available, park at a nearby courtesy dock.
  • The trailer should be backed down the launch ramp until its wheels or fenders are submerged to a similar water level as when you launched your boat .
  • Be mindful of wind and current as you position your boat to load on the trailer.
  • Use just enough power to control the boat. Slow is pro, and you’ll have more time to react.
  • Aim the bow of the boat to the trailer winch stop.
  • If the ramp is shallow, trim your outboard or sterndrive up so the prop (propeller) doesn’t hit the bottom.
  • If your trailer is positioned at the correct depth, your boat should glide onto the trailer—use a little throttle to push the boat up further if needed.
  • The tow vehicle driver should put the vehicle in park using the parking brake, and get out to secure the trailer winch and the safety chain.
  • Once you pull out of the ramp, use a staging area off of the water to unload your gear, attach the transom straps and trailer lights, and prepare to hit the road.

Be sure to consult our other launching and towing guides to ensure you’re best equipped for your experience heading to and from the launch ramp:

  • Launching a Boat: Step-by-Step Guide
  • How to Back Up a Boat Trailer
  • Choosing the Right Tow Vehicle

Now, let’s walk through some of these steps in a little more detail…

Want help paying off your boat? List it with us

Dropping off your driver and passengers

Approach the dock to drop the vehicle driver and passengers off. If there’s a courtesy dock or dock away from the launch area, it’s okay to tie up while you wait for the trailer. If not, move the boat away from the ramp area and wait for the trailer to be backed down.

Backing up the boat trailer down the ramp

Boat Launch Ramp.

The driver who gets the tow vehicle should get in line – if there is a line – to take a turn in backing down the ramp to retrieve the boat .

If you and your crew remembered to observe the water level relative to your trailer wheels or fenders when you launched, back the trailer in to that same depth.

The driver can now put the vehicle in park and set the parking brake, and get out to help load the boat.

Loading and positioning your boat back on its trailer

Simultaneously, the boat driver should pay attention and be in position to approach the ramp when the trailer is in the water.

Once you’re ready to load, you’ll want to be mindful of wind and current that could push you off course as you approach the trailer, and plan ahead by starting a little upwind, for example.

  • Use just enough power to control the boat. A slower speed gives you more time to react and keep the boat on course.
  • Aim the bow at the trailer winch stop. Most boat trailers will self-align as the boat glides onto the trailer.
  • If the ramp is shallow you may need to trim your outboard motor or sterndrive up a bit so the prop doesn’t hit bottom.
  • If you have your trailer at the correct depth, the boat should glide onto the trailer right to the winch stop, or close to it.
  • Use a little throttle to push the boat up to the stop, or have your helper attach the winch strap to the bow eye and use the winch to pull the boat up the watercraft stop.

If the boat ends up a little crooked on the trailer, back down the ramp just a little to allow the boat to float and center itself.

Pro Tip: Do not “power load” your boat—using excessive engine thrust to drive the boat up onto the trailer will damage the ramp by washing away the lake bottom. Better to back your trailer in a little deeper in the water.

Positioning Boat on Trailer.

Preparing to hit the road

Once the boat is positioned properly on the trailer, secure the winch at the bow and secure the safety chain. The boat driver can stay in the boat while the vehicle driver pulls up the ramp.

Drive to the staging area, or away from traffic, to unload coolers and gear from the boat, secure transom straps and trailer lights, and get ready to hit the road.

Clean, drain, and dry to remove any aquatic invasive species

Boat Wash.

Before driving away, it’s important—and in most places, the law—to remove weeds from the boat and trailer and to drain the bilge , live wells, and bait wells before driving away from the ramp. This prevents the spread of invasive species like milfoil and zebra mussels. There may be signage at the ramp with guidance for this procedure or check with your state DNR for local regulations.

Boatsetter is a unique boat-sharing platform that gives everyone — whether you own a boat or you’re renting — the chance to experience life on the water. You can list a boat , book a boat , or make money as a captain .

Start offsetting the costs of boat ownership as soon as you list with Boatsetter!
