Need help finding the right winch, let’s say you have a boat that weighs 2,500lbs. You would then get a winch that is rated for 2,500lb or more. Generally winches ratings are 2 to 1 when used for a boat trailer.
What that means is that in most situations a winch can be used with a boat that has twice its capacity.
So the same winch could be used for a 5,200lb boat in most situations so it would be more than enough for you
