The lake I go to has metal floating docks with old tires as bumpers. They always leave black marks which I have to scrub off. Last week a gust of wind blew me onto a metal corner of the dock on which the tire had come off. Thankfully it left only surface scratches in the gelcoat which I easily repaired, but it could have been a lot worse. Any suggestions on something that would protect against these sub par docks? I have fenders which help but often just get pushed up from in between the boat and dock. I'm considering dockmate rafting fenders (http://www.overtons.com/modperl/pro...Rafting-Fender&i=87169&aID=602B1&merchID=4006) but not sure it would protect against the metal corner that got me last week. I'm tempted to buy a real dock corner bumper and just consider it my contribution to all other boaters there.
