To build a new wooden boat, you can use epoxy for ease of use and performance. Or then use the traditional methods which don't require using epoxy at all. If one has thick enough and good enough lumber I can't see a reason to use epoxy on a small boat. Everything can be done without glue, and if the boat is done without glue it's always easier to repair or replace a damaged piece when you don't have to fight with glued seams.That was the idea with classics: when something was broken you could pull the broken piece out and replace it. It just doesn't do with epoxied structures.
