I have a new custom made cover for my 22' Sweetwater. The snaps are just below the rail around the boat and along the bottom of the deck in the front. Everytime it rains, I find a wet floor around the side doors and in a few other places. I thought the cover would prevent water from coming in and would keep my boat dry. Since I am new to pontoon boating, I am not sure if I should be trying to keep the floor dry or not. Is the carpet designed to get wet repeatedly or should I try to keep it dry? Do I need a complete cover over the entire hull down to the pontoons? I trailer with the cover on, and did not experience any problems. Is this a mistake?
