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.

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
James - 07/18/2020


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.

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

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.


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


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.


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
Richard - 07/25/2021


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.


No problems. It has worked great.

Fast shipping .... well done !


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.


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.


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.


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!

Wonderful! Husband hated the idea until he hooked it up. Now he wont use anything else.
Julie M - 03/22/2021


I haven't installed this part yet but I have to say the service was REALLY fast. I ordered it on Tuesday and it was here Thursday. That's great service, after I install the winch I'll write another review. I'm sure there will be no problems with the equipment.

the mounting holes dont quite line up with the crank holes so I had to drill new ones to make it fit the trailor. also the cables should be longer to reach all the way to the full size truck battery. other than that it works fine
William - 06/17/2019


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.


Works greatly so far, loads my 18’ Lund Ski/Fish, groans a little at some points in the process but I guess that’s normal for an electric winch.


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.


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!


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.


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.


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?

  • Is Fuse or Breaker Needed When Installing Dutton Lainson TW400 Strongarm Winch
    The power wire of the Dutton-Lainson TW4000 StrongArm Electric Winch # DL25200 has a circuit breaker built into it so you would not need to install any additional fuses. The breaker is rated for 40 amps. I attached a review video for this winch for more info as well.

  • Replacement Winch For Fulton Winch T2625 For 22 Foot Grady White With In Board/Out Board Drive
    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. I recommend to use the Marine Dutton-Lainson TW4000 StrongArm Electric Winch part # DL25200 which will provide you with a 4,000 lb capacity...

This is a marine winch that can be used with a boat up to 4,000 lbs; it includes a wiring harness with a 25' positive battery wire and 8' ground wire as well as a 20' strap which is 2" wide. The StrongArm has a brushed stainless steel front plate and weather-resistant case to protect it from being damaged by the elements. I have added a link to a video review of this winch...

A comparable electric model is the Dutton-Lainson # DL25200 Electric Winch with 1500 pound capacity featuring a sturdy 20' by 2” strap, and it includes wiring harness for connection to your tow vehicle. Installation will require some drilling for mounting to the Kar Kaddy frame, and bolts, nuts, washers and lock washers to attach. I have included a link to this product and a review video.

    While I wouldn't be able to tell you what may or may not be legal in any one state, I can tell you that the winch you asked about, the Dutton-Lainson TW4000 StrongArm Electric Winch # DL25200 does have the capability to pull a wheelchair into a van. I do have to say that it should not be used with anybody on the wheelchair, as winch manufacturers, including Dutton-Lainson, specifically state they should not be used to transport people.

  • 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...

  • 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. In order to check this you will want to remove the winch cover to observe which parts are moving as the load slips out. This should pinpoint...

  • Dutton Lainson or Fulton Powered Boat Trailer Jack Recommendation
    For a boat that weighs 2,500 lbs the Dutton Lainson TW4000 part # DL25200 would be the most appropriate choice. The Fulton F500620 has a 7,000 lb capacity and would work great but would be quite a bit more than you'd need. The DL is a very popular option with our customers and it's been reviewed highly so I would recommend it for you.

  • Electric Boat Winch Recommendation for a 3,900 lb Boat
    Your boat should weigh right around 3,900 lbs according to research I did so for a winch designed for boats that weigh right at 4,000 lbs the Dutton Lainson TW400 # DL25200 would be an excellent option. This also comes with wiring for the vehicle side of the winch too so that you can plug it into your vehicle when needed.

  • 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.

  • 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.

You will run the positive wire from the harness under your truck, avoiding any exhaust or moving parts to the positive post of your battery under the hood.

The TW4000 is rated for boats that weigh up to 4000-lbs so it will have plenty of capacity for your 2800-lb.

  • 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.

    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.

This boat winch has a high-impact weather-resistant case which makes it perfect for marine applications. Another great feature is the freewheel-out clutch which allows you to pull the strap out by hand. I have attached a review video for you to check out as well.

  • Recommended Electric Winch for Center Consult Key West Fishing Boat
    The winch for a boat trailer is selected based on the weight of the boat. As a general rule of thumb we use a 2:1 ratio meaning the winch needs to be rated for at least half the weight of the boat. If the trailer has rollers or bunks this can increase the ratio but 2:1 is still a safe bet. I looked up some stats online and it appears to be a fairly light boat so pretty much any of our winches will do the job.

With that being said, all of the Dutton-Lainson StrongArm Electric Winches have some sort of built-in manual override. If they did not come with an emergency crank handle which was the case with part # DL25200, you can manually operate the winch with a 5/8" deep well socket.
