For the past couple of years we've been towing our 22' Cruiser with transom straps securing the boat to the trailer. Over the weekend I noticed that the straps seem to be causing some wear on the gelcoat where they contact the hull. Has anyone else seen this in wear pattern? We're thinking of running a strap over the gunnels, or possibly just placing a chamois between the transom straps and the hull when trailering. At this point the wear is negligible, but we'd like to stop it before it becomes an issue. Any thoughts would be appreciated.
