Ncik, Good idea to use some unidirectional on the deck, that will take care of the compression stress. Iwasn't going to have the deck at the centreboard opening single skin but I was goin to use H160 foam instead of H80 foam. The whole boat is mostly Divinicell H80 foam 10mm thick ( 80kg/ sq m density ) except for high stress areas which have H160 foam. I'll probbaly go with the timber sheer clamp since its easier to do.
The diagonal stringers I proposed run between bulkheads and ring frames diagonal to the axis of the boat so that the boat works like a truss. But I guess if I go with the -45/+45 layup on the inside, the fibers will are in the correct orientation.
Yes that chainplate is really cool but a bit overkill on a 12ft skiff... think I will do one to keep up with the Joneses. Yacht Bling...
