My last boat Diva was a could moulded kauri ply(3skins) over mahogany frames, epoxy
saturated...when I sold it last year, the surveyor
was very impressed...a 40yr old boat and nothing had moved, no joins detached...perfect.
But as previous posters have said, this is probably not what you would call a "timber" boat, even though it is wholly constructed of wood.
This is a great construction method that has stood the test of time.
