Yes, U.S. composites. I ended up with 3 layers of 1808 biaxial ( 0-90 deg. thread orientation) and a layer of 3/4 oz. mat for the outside layer. Being my first fiberglass project, I relied on the advice of a fiberglass guy and everything looks good so far. I am going down today to grind and fair it....
Interesting to read earlier posts and the varying differences between boats over the years. Our cockpit bulkhead core is 3/8" on Kinesis. Very surprising to see they went back to the double quarterberths at one point. Maybe that was a custom order?
