Thinking ahead of time for getting my boat off the ramp when water is low,,, Should I buy maybe an electric boat winch seeing my boat weighs so much? I have seen the water get very low come winter water levels on many lakes here in the Midsouth and would hate to have to abandon ship one to any low water conditions come Febuary, March.... Any suggestions on what to buy and how strong a winch to get for my Ranger fish-ski 397xt? She's 19.5 ft and I'm sure over 2,500 lb s.....
