You are looking at the underside of the top deck. Honeycomb is in place and the top 2 layers glass has been vacuumed down. With the Formula hull that I raced in 08. There was a lot of info that was learned mostly with weight. This hull will be built much different than the first three hull that I have done. The honeycomb that has been cut back on the left side is for the Walt Barney single 20 oz fuel tank. . My Formula hull only had a 18 oz tank. The 18 oz tank was almost not enough fuel with high output CMB 67 with a 12 mm carb.
