Well, most of the outside structure is complete and prefaired so it's time to start covering things with fiberglass cloth. Adding cloth adds some stiffness to the plywood, but mainly its to provide a moister barrier and also more resistance to impact and abbrasion. I started with the transom, then the decks and the cabin top. I used 6 ounce e glass cloth for this. I had the whole day off and was able to get the whole boat covered. Wetting out all that cloth took a lot of epoxy. I think I still have enough left to finish the outside of the boat though. I just bought sails for my racing boat and don't want to have to tell my wife I need to spend another $500 on epoxy!
So now my boat is waterproof! I could plunk it in the harbor right now and go float around with no ill effects to any of the wood. Sweet! It's officially a boat!
