1972' Seafari 25 Rebuild Project

Working under the deck: I never said it was easy, just much better than pulling the cap.

I cut out all three bulkheads and worried that the hull would deform and my deck cut outs not fit. No worries, nothing moved at all. Still a better idea to do them one at a time.

For the added bulkheads forward of the tank bulkhead, I used cardboard to template, then did each bulkhead in two sections, port and starboard. That way I could cut the bulkhead so it hooked over the main stringer. Glassed the two pieces back together and tabbed all the way around, main stringer , outside stringer, inner liner, etc. itchy, itchy itchy! kind of ugly, but it worked.

Having had a pretty severe amount of hull damage and not being able to see possible damage on the outside of the secondary bulkheads, I went over kill. Put in two full bulkheads( one to continue the vertical part of the inner liner aft of the bunk and another a few feet forward, just where the worst hull damage was) and a half bulkhead half way between the tank bulkhead and the bunks

Tried hard to avoid hard spots, but made one anyway. A couple of years later, starting to see stress cracks in the gelcoat, I added stiffening to the area between the forwardmost new bulkhead extending through the original forwardmost bulkhead. Seemed to solve the problem.
