I forgot to mention one little thing in that last post – we’ve reconsidered the material choice for the boat, and have decided to build the hull in glued lapstrake plywood.
What brought that about was a discussion of flotation, and wanting to get it figured out right from the beginning. We talked about using foam or air-bags for flotation in a conventional clinker hull, but the conversation kept coming back to maintenance and ventilation. In the end, a suggestion was made to do it in glued lapstrake plywood, with built-in water-tight compartments. That should give us a lightweight self-recoverable boat.
After all, the plans we’re working from are designed for that method, and it will let us gain experience in another type of construction!
