Electric Winch Recommendation For Pulling A 4850 Lb Boat Out Of The Water Onto A Trailer  

Question:

I would like to know what winch you would recommend to pull an 18 shark cat boat out of the water onto a trailer? I am looking at the S3000. The boat weight is approx 2200 kgs.

When winching your boat onto a trailer a common ratio for determining your winch load capacity is 2 to 1. For example, a 5000 lb boat would require a 2500 lb winch. There are other factors, however, that will determine the appropriate winch size for your purposes.

The ratio can be stretched to 3 to 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 to 1.

The winch you have mentioned, the Superwinch S3000 Trailer Winch, part # SW104118, will work for your 4850 lbs (2200 kgs) boat if your are using them in a situation where the trailer has rollers or the boat would float most of the way on the trailer.

If you are winching the boat on wooden bunks, or the boat must be winched most of the way out of the water I would recommend the Bulldog Winch # BDW10029

If you are deciding between the two winches the largest winch # BDW10029 will always be the best choice. The larger winch will not have to work as hard as the lower capacity winch and this will improve performance and help extend the life of the motor.

I am including a link to a FAQ page on electric winches.
