Determining Your Load Capacity

A common ratio for determining your winch load capacity is 2:1. For example, a 2,000-lb boat would require a 1,100-lb winch. There are extenuating factors, however, that will determine the appropriate winch size for your purposes.

The ratio can be stretched to 3:1 in instances when the trailer in use has high-quality rollers and is most commonly used on ramps where boats float most of the way onto the trailer.

In contrast, using a boat trailer that has wooden bunks, lacks self-alignment capabilities, and is most commonly used on ramps where the boat must be winched most of the way onto the trailer reduces the ratio to 1:1.

Note that pontoon trailers and other special designs require special consideration when determining winch capacity.

Percent InclineMultiply By
Level Surface10.0
5 (3 degrees))6.67
10 (6 degrees))5.02
20 (11 degrees))3.40
30 (17 degrees))2.61
50 (26 degrees))1.86
70 (35 degrees))1.53
100 (45 degrees))1.29

Determining Your Rolling Load Capacity


To calculate your winch's rolling load capacity - the amount of weight it can pull up an incline - you must multiply the winch capacity by a factor determined by the degree of the incline.

The multiplication factor shown includes a 10 percent rolling friction factor. Note: A 5 percent - or 3 degree - incline is a 1/2' rise in 10'. Follow the chart to determine your winch's rolling load capacity.

Mounting Your Winch



All Dutton-Lainson StrongArm electric winches are built for multipurpose hauling and pulling operations. They are not to be used as hoists for lifting, supporting or transporting people, or for handling loads over areas where people could be present.

Take the strain out of loading and unloading your boat with this electric winch, featuring a power-in switch and a freewheel-out clutch. This DC-powered winch is designed for boats up to 4,000 lbs and includes a wiring harness for easy installation.


I love the winch for the strap is a great upgrade than the power winch with metal cable which would rust, wire strands would break off, and cut your hands, and the cable would not retrieve back on winch even. The cons I see is the strap has become dried out after use on the end at the hook and it wants to double over on same area. Another concern I have is you have to tighten the clutch knob very hard when retrieving in or it will back off and free spin back out. Just have to wait and see if this becomes a problem in the future.


Put this winch on my Ranger 620 boat trailer a year ago and love it! Haven't had a single problem and it helps trailering when I fish alone. I ran power and ground from my truck battery to a back bumper plug, and have a separate removable cable (shown in pic) to connect truck plug to the winch plug. Grounding to the truck didn't work for me. I have another spare cable and plug rolled up and attached to my trolling motor battery for when my buddies drive. Winch prevents power loading and drawing sand into the motor. DL24055 adapter plate was needed and I put a coupler lock up through the middle of the winch to prevent theft and I bought a cover (shown in pic) to keep the rain out. etrailer sales and support are absolutely fabulous! They helped me figure all this out.


I am a 77 year old man and having to hand winch my small sailboat up on a shore ramp that I have. It was getting to be a bit much, so I decided to look into a 12volt winch. The Dl25200 fit the bill, works great. I have a 12volt battery next to it and a 10 , watt solar charger to keep the battery up, I hope. Time will tell. The service at etrailer was great, good price and fast shipping. Thanks


Works great, fit my trail weight boat trailer, with a 24 foot pontoon



Great use it weekly


They provided prompt service and gave me some valuable input about winch operation.



Works well, thank you.


This has been a great purchase. As I get older it is becoming more difficult to load my boa. This has made using my boat much easier.

Frank H.




I installed this winch as a replacement for the standard winch on my Magic Tilt trailer for my 21ft. SeaFox. I replaced the winch so that my wife would not have to hand crank when helping me load the boat. I only wish I'd done it sooner! It works like a charm, the install was simple and it has held up well. I keep the winch covered with a tarp to keep the rain off of it and I'm sure that has helped. The SeaFox weighs about 3000# plus the weight of the motor, fuel and whatever other junk we've got onboard. If you are looking for a good electric winch to make your life easier, I recommend this one.

Michael H.


After a year of use, we are still very pleased with our purchase and would still recommend this winch.


This winch has performed great! I wish I would have put this on a long time ago. I'm pulling a 18' aluminium boat on the trailer when power loading is not an option.

Only thing to consider is your path for the wires. I started out following the wiring harness from the back of the truck and ran out of wire. I had to follow the frame on the opposite side for the shortest run. This works fine.

Agian, I sure wish I would have put this on years ago!


I use this to load my boat. Works great. Easily pulls my 16' Alumacraft boat the full length of the trailer. I also like that this winch uses a strap instead of a cable.
One suggestion is to make sure the black clutch knob stays engaged during operation. Also, order the wiring plug cover. It is not listed but available.


Installation on the trailer was straight forward. Running the wiring from the battery to the rear of the truck, and doing a nice job was a little tough.
The winch has worked as advertised , and loads my 18 ft boat without any problems. But having to plug the power cord in at the bottom of the boat ramp is an additional step to get used to.


Beware! Read the specs carefully. We have a 3,900lb boat and a 32 roller trailer. On an average incline boat ramp the winch can barely pull the boat up. The last 3 ft or so the winch cuts out.
Their rating are based on something like a 6 ft pull.
1,500 lbs pull.

Previously we had a Powerwinch brand 4 k winch that pulled our boat out fine. Tree fell on it so we needed a replacement .

The next size up in DL is a 9,000lb winch
We thought that was overkill. Turns out that was probably what we needed. It has a 3,000 lb pull rating. If you take your boats to different launches you know they can vary a lot on the incline. Wouldn’t be fun being at a busy ramp and your whimpy winch couldn’t pull your boat on the trailer. Very disappointed in this winch.
Another $300 boat anchor.


Purchased a strong arm electric winch to get our boat out of the water. Should have purchased it at least 20 years ago. It sure works great and makes loading the boat so simple and hassle free. Great for us older folks.


Great product, used it every day for a week on a 19' glass boat/roller trailer. Used a lawnmower sized deep cycle battery mounted on the tongue in a box. The battery has many more pulls left in it without a charge. Increasingly, boat landings in WI are no power load. This is much safer and easy on the body.


Boy what a difference this product makes, should have had one years ago. Easy to install and works great (no more hand cranking the boat onto the trailer). I would recommend this winch. Top it off with the great customer service at etrailer.


Good quality, works fine although it grunts a bit on the last couple of feet. I appreciate the use of a pretty universal power connector. Changes of or additional vehicles made so much easier. Like the strap rather than wire rope.


This is a game changer for my husband who has a bad back. Makes loading the boat on the trailer so much easier! Works like a charm!

Julie M.


Wonderful! Husband hated the idea until he hooked it up. Now he wont use anything else.


This winch works great on my Lund boat with. 60 hp Mercury. I can now easily load my boat onto the trailer even with arthritic shoulders. Takes a little longer, but oh so much nicer on my arms!


winch worked great easy to install on my boat trailer but the cable provided was to short



so far so good would like to have option to purchase male and female plug in connectors like the ones included with the winch

by: 06/13/2022

I just used it for the second time on my 19 ft Lund boat works great! Could not believe it bolted to the same bolt holes of easy load trailer crank wrench.


Wow! These guys are the REAL DEAL! I shopped around and etrailer had the perfect winch for my boat, the most detailed specs, the BEST PRICE by far, FREE SHIPPING and on time delivery! Need I say more?


great product so far! It would be nice if a few more mounting holes were drilled in the mounting plate to give you a few more options on mounting.


I am totally pleased with everything about the winch and etrailers service. Read the instructions as you need to loosen tension on the spool when you store for a long period of time. It is easy to release after you do this, but it is easier to avoid by following instructions.


I particularly liked the number of product videos available on the site. One dealt with the wiring and plug connections on this winch. Shipping was very fast, too. I'd use etrailer again for future related purchases.


Wow! This winch works great! Pulled my pontoon boat right up on the trailer with little effort. I'm happy.


Receipt of the trailer hitch was fast. Very well packaged. Hitch is every bit as expected. Very happy with this purchase!

  • Electric Trailer Winch Recommendation for a Boat and Gear Weighing 4,500 Pounds
    Because a boat is a floating load (rolling load), you will not have to have one that matches the weight of the boat. But if you want to go larger you can certainly do so. The Dutton-Lainson StrongArm Electric Winch, # DL25200, would be more than enough for your application. I have included a link to the installation details for you to view. i have also included a couple of links to FAQ articles on choosing the best winch and wiring a winch.

  • Clutch Does Not Lock on the Dutton-Lainson TW4000 StrongArm Electric Winch
    There could be two possible reasons as to why the clutch is not engaging when you are pulling in your boat with the Dutton-Lainson TW4000 StrongArm Electric Winch part # DL25200. The first reason is the simplest to fix and it entails tightening the clutch which is explained on page 4 of your owner's manual. The other possible cause is a faulty brake.

  • Recommended Electric Winch to Pull a 4,200-lb Boat Onto a Trailer with Rollers
    Since your boat trailer has rollers on it you can use the Dutton-Lainson TW4000 StrongArm Electric Winch # DL25200 which is rated for a 4,000-lb boat when no rollers are present. This boat winch has a high-impact weather-resistant case which makes it perfect for marine applications.

  • Would a Dutton Lainson Strongarm TW400 Replace a 1802A Winch
    Your Dutton Lainson 1802A winch attaches using a very standard style bolt pattern. The Dutton-Lainson TW400 StrongArm # DL25200 also attaches to the same universal style winch attachment bolt pattern so it would work well as a replacement.

  • Can Dutton-Lainson TW4000 StrongArm Electric Winch Serve as Boat Strap When Traveling
    I spoke with my contact at Dutton-Lainson regarding the TW4000 StrongArm Electric Winch # DL25200 referenced in your question. She stated that the winch is not designed to serve as a boat strap when traveling so this is not recommended. Once pulled in and onto the trailer with the winch, the boat should be safely secured to the trailer using additional mounting straps and hardware. This particular winch has a load capacity of 1,500 pounds for a boat of up to 4,000 pounds. I have attached...

  • Recommended Power Winch to Pull 3,500 Boat onto Trailer
    I recommend the Dutton-Lainson TW4000 # DL25200. It's rated for up to a 4,000 boat and is powered through a quick disconnect hooked up to your tow vehicle's battery. So there's no need to add a battery onto your boat trailer.

  • Will a Nylon Roller Affect the Weight Capacity of the Dutton-Lainson TW4000 StrongArm # DL25200
    Typically for boat winches the winch can pull a boat that is twice its rated capacity. If the trailer has good rollers then you could stretch that capacity to 3:1 but if you have wooden bunks it is best to stick to a 1:1 ratio. The nylon roller shouldn't affect the weight capacity of the winch and since the Dutton-Lainson TW4000 StrongArm # DL25200 is rated for over twice the weight of your loaded boat you will not have any problems at all. I have attached a review video and installation...

  • Lift Capability of Dutton-Lainson Strong Arm Electric Winch Part # DL25200
    Assuming that your trailer has bunk rollers instead of boards, the Dutton-Lainson Strong Arm Electric Winch, part # DL25200 should be able to handle that 2500 lb boat with no problem. If the trailer just has boards, the resistance they would cause against the bottom of the boat would limit the capacity of the winch. I have included a link to the instructions for you to review.

  • Recommended Electric Winch For Loading A 600 lb Boat In Shallow Water
    The Dutton-Lainson TW4000 StrongArm Electric Winch # DL25200 will be a great choice for a boat of that size. The 1,500 lb capacity will be plenty strong, even if the boat is loaded close to 600 lbs you will still be well under the max capacity. Even with dry wooden bunks, there will be no risk of an undersized winch. I like this Dutton-Lainson winch because the housing protects it from the elements, which is ideal for marine applications. They are made here in the USA as well.

  • Dutton Lainson Powered Winch Recommendation for 1,800 lb Boat
    Generally when picking out a winch for a boat trailer the ratio is 2 to 1 meaning you would need a winch with roughly half the capacity as the weight of the boat. With good rollers and a short winching distance the ratio increases to 3 to 1, but with long winching distances and wooden bunks like what you currently have the ratio is 1 to 1. The 4,000 lb Dutton Lainson TW4000 part # DL25200 you mentioned would be more than adequate and would work great.

    The T2625 Fulton Winch is an older model High-Performance 2-Speed Trailer Winch that can handle 2,600 lbs. Since I am not sure which model Grady White you have I cannot say for sure that is has enough capacity. The 2625 is for cable use only. With that said, most likely your boat is heavier than the capacity of the Fulton winch according to my research.

The power outlet on your truck would not have the amperage rating to power this winch. The wiring kit mentioned has thick gauge wires that run straight to the battery. I wasn't able to pull up any info on your trailer but as long as it has a winch mounting plate that is standard to most winches it would work fine.

    The Dutton-Lainson TW400 StrongArm Electric Winch # DL25200 is rated for use with boats up to 4000-lbs total weight. Having roller bunks provides a definite advantage over standard carpeted bunks since this trailer feature reduces friction.

  • Winch Recommendation for Boat Trailer to Allow Boat to Easily Make it onto Trailer
    The higher capacity winch you go with will allow an easier crank than a lower one.

These conditions just have to do with how much resistance your boat will be experiencing.
