I have a 85 bayliner, 19.5 ft and the floor is soft and soggy in a couple places. I tore up the carpet and Some of the wood. I just don't know exactly what steps to take. I've been doing some research and think I have an idea but want to make sure and this seemed like the place to find out. Do I just put down new plywood and fiberglass over that and then carpet, or is there more steps to do? I'm a first time boat Owner but handy so I know I can do the work. Any help would be much appreciated...
