Re: 1977 Chieftan 22 new deck
i'm with the "use plywood" folks. weight is the big advantage of tinnies over glass hulls, and even using 3/4" plywood instead of the 5/8" the factory used on most of the bigger boats will screw up your interior panels etc alignment.
if you have this wood and it looks nice, use some of it for superstructure and trim. like a wood "leaning rail" on inside of transom or gunwales, so you don't burn your thighs on hot aluminum while hooked up to a big fish......
