I'd be interested in the ones on steel boats and the John Leather books.
Thanks, Dave Cannell

By the time you build out of FRP you might find your weight savings
are not that substantial. Have you checked out Ian Oughtred's
designs?

I always assumed that one advantage to lapstrake is that the hull is
drier, that is, water does not travel up and over the sheer as easily.
This allows the boat to have slightly less freeboard and as a result,
less weight (mabey) and less windage.
