Keeyaawww, I go through da lock and dam alot and I had dis nice idea (I havent tried it yet though) to put foam pipe protectors ,the kind that looks like swimming noodles,or catfishing noodles like some of us use dem for, but dese have a cut up da middle to help wrap dem around da gunwale, you can use a type of marine glie(dis is why I havent used it yet, I wanna try a type of tape that can be removed if I ever sell my boat) but all you have to do is open the foan up at the split and slip it on the gunwale. It come in about 6 foot sections dis is da kewl part, if you ever damage it, a small peice can be taken off and replaced a section at a time. It can also be used as a boat bumper when aproaching docks and if you happen to walk on it it will collapse so not to trip you. Dats da theory anyhow....Hope dis helps and if you come up with a nice tape brand Please let me know. Tanks to all...like dey say in french, merci beaucoup.
