I thought of something similar with foam, I was going to take a marine grade foam (like Divinycell) and make box stringers or just stand up a 1" piece vertically and fit them to the bottom of the boat. Wrap them with several layers of glass and then tab them in very well. Most of the strength would come from the glass but thought it might end up heavy in the end due to needing more glass than if it had a wood core with less thinner layers of glass. Also I thought of using Coosa, this would be the strongest and would not need as much glass over it just tabbed well. I know that the wood is strong for the small amount of weight that it adds but then I'm back to the rotting issue. I want this boat to last 25+ years. Also I would like to keep it light as possible but don't want to loose any strength.
