I was on this forum which is pretty active for doing the kind of work you will likely need to do.

Here is my thread I started on that forum a few years ago. My boat was a lot of work due to having to replace stringers, bulkheads and floor. Boat manufacturers until the late 90's or so mostly used plywood for stringers/bulkheads and floors but they only coated and tabbed them using regular fiberglass resin. Fiberglass resin does not waterproof wood long term so you get rotting. I rebuilt mine with new plywood and tabbing using epoxy. I also used epoxy for all screw locations into the wood. My boat is now better than new structurally speaking. It legally holds 13 people so with grandkids we will keep it for a long time so it was worth it to me. It came out great and we still use it often.
