I also unload & load by myself most times with a 47 Fountain SC. I set up the trailer to make it as easy as I could with a boat this big. I put a warn 2000 lb winch on the trailer with its own battery. I bought a mile marker wireless remote & reconfigured the relay set up in the winch to work with this remote. My trailer also has to be in except for the front 6 feet. The winch just pulls the boat where I need it to be without any trouble. It made loading fairly trouble free.

I have that same one, and it doesn't even hardly budge my 17,000lb cruiser
