The size winch that you will need depends on a couple of different factors. I have included part of our hand winch FAQ below regarding boat winches and have linked the FAQ article for you to view.
Finding the Right Capacity Winch for your Boat Trailer
Boat-size-to-winch capacity is generally 2 to 1
With good rollers and short winching distances, increase the ratio to 3 to 1
With wooden bunks and long winching distances, reduce the ratio to 1 to 1
For example, a 2,200-lb boat generally requires a 1,100-lb winch. If the same boat were winched a short distance with a low incline and with rollers in good condition, it can be safely winched with a 900-lb winch. The boat requires a winch with a 2,200-lb capacity if you are winching a longer distance with more resistance; for example, if the trailer had carpeted, wooden bunks or was set on a steeper incline.
So based on the above information, the Fulton XLT Winch, # F142425, could potentially handle a boat that weighs 9,600 pounds at a 3 to 1 ratio. But is probably safer to say that it can handle a boat that weighs between 3,200 pounds and 6,400 pounds.

I have an older 23 foot Sea Ray. The boat, without the v8 engine, is supposed to be about 4000 pounds. Fully loaded, I think including the trailer, it is supposedly about 6600 pounds. We can pull up a relatively steep hill and run the winch off an isolated battery. What winch do I need? I would prefer a strap, rather than a cable, if possible.
