Does anybody use these in their slip? They are like a floating bag your >boat slides on top of then you put some pool chlorine inside to keep >growth off the boat. They have flotation at the bow and along the >sides. At the stern you tie it up when you are in your slip then untie >it and it is weighted to sink to let your boat out. > >If you use or used one what do you think? > >Thanks, > >Rick We have one in out marina in St Clair, MI--looks to be a lot of trouble with very little benefit. Owner has a lot of problem keeping the "float" under the boat (26-28 go fast) when he tries to enter his slip. Once he is over it, he then has to inflate it and it has a tendency to move out from under his boat. Last time I watched him tie up...it took a good half to three quarters of an hour to get it inflated. Where we are in Michigan, all it will accomplish is to keep the "green slime" off the bottom, maybe save him one half MPH top end. I don't know how effective it would be in salt water.
