Getting ready for Kevlar on the tube to hull and carbon on the bulkhead to hull. The other bulkheads fit better. This one was hard to reach, marked with a sharpie on a long stick, a flashlight. droplight, and binoculars. Looking through 17 feet of black carbon hull at a black carbon bulkhead we missed it a bit and this bulkhead will be hard to reach once the hulls are joined so a little extra work now will save from working through a 4” port hole next week.
