I had to spend some extra time on this stern section due to dropping the stern during the turn over process and the hull landing on the post and cracking. The butt straps in the pictures were lengthened and extend down into the stern area. They were tapered to fit into the tight area, and notched to cover the surface of the exposed area. We screwed and glued them in place, then added the fillets over the entire structure. It is now very stiff.
