So no one wants to talk about electric boat winches. I will then. I think the one you are refering to is rated at 4000lb, which is fine for most small boats. I put a used one on my trailer, it was rated at 6000lbs, and so far am very happy with it. Mind you the boat only weighs about 1500-2000 lbs. Most of the time I am able to pull the boat to within 5ft of the winch so I am using very little cable. The only time I was a little concerned was putting it on at Kitty Coleman at a very low tide, I effectively picked it up dry. It was very slow but dragged it up the bunks fine, much better then a hand crank. IMO the biggest limitation is the dependence on battery power, mine has provision to use a crank handle, I don't think I would go without that feature. My 12v comes from my vehicle battery, I don't run run the engine on short pulls (steep ramps) , but do on long pulls where I know my park brake will hold ( manual transmission). If I was younger I don't believe I would not use an electric winch, but at this point I do appreciate it.
