Outer laminate A specification

After a great deal of huffing and puffing, thinking about e-glass, s-glass, carbon fiber and Kevlar materials. I have chosen to use the following for the A side specification.

The winner is two layers of a 7781 style 8.9 oz aerospace e-glass cloth from BGF. I think this will be a good match to my choice of the s-glass 6781 style for the inner B specification.

From the very beginning I have wanted to vacuum bag the laminations on the outer hull side, and I have seen how a very high quality laminate is achievable with two layers this style of cloth. It seems quite clear to me that the hand lay up of the inner hulls will seal the foam strips making the vacuum bagging of the outside hulls relatively straight forward.
