Hi,

I'm currently investigating the idea of building a carvel hull
completely out of plywood. Ribs, strakes etc all from plywood. The
interesting thing to me is can I do all the work up front and have the
plywood milled on a CNC machine. The hull should then be easy to
assemble.

I've seen various clinker/lapstrake hulls built for small rowing skiffs
that seem to implement the idea pretty well.

I've also played around with scale models I've designed and everything
seems to work out.

The current problem is how to work out bevels for both the ribs and the
strakes. Is there a formula for this? Ideally the more general the
solution the better e.g. would work for a scale model as well as the
full size.
