Before you buy a new winch spend some time and look at the Trailer Tugs. It took be a while to find them as one needs to know the correct term when searching on the Web. The trailer tug sits under the tongue of the trailer and so will pivot the boat on a dime as they say.
I have used mine to move around a 3500 lb. boat and trailer up my driveway which has a 6% incline. I got one with 3 wheels and an AC motor with auto braking. It takes very little room for storing it with the handle type that pivots up 90 degrees.
