I am just finishing building a Devlin designed one man duck boat. I used 1/4" tongue and groove 1x4s for the decking material. Will 2 coats of epoxy and a couple of coats of paint prevent any leaks from the top decks, or should I also fiberglass the top decks? I used Titebond III glue all the edges of the planking, and will put at least two coats of epoxy and paint on the underside of the decks before I attach the bottom.
