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 Incline | Multiply By |
|---|---|
| Level Surface | 10.0 |
| 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 |
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.
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.
