I bought a Gorilla Winch off e-bay... I have a deep cycle battery / trolling motor battery and it plugs in up near the bow. I had a receiver hitch built into my hull during construction. Check my rig review think I have a few shots of the "receiver" I can snap a few of the winch I just tossed a new one on.
I winch off a dangforth anchor but if you don't have anything to secure to you might as well push

I've winched anchor back multiple times to the boat without it budging me an inch.
