Question for the Forum. How are the sheer planks built in a Friendship sloop? The planks according to Chappelle's book are two inches thick and the steam bent frames are let into the outer edge of them. The inboard edge receives the deck beams. These sheer planks are two inches thick or more and contribute greatly to the boats longevity. I think the decking covers them. I'm not sure how they get all those scarfed planks to follow the sweep of the sheer. Anyone see how this was/is done?
