I would think you could replace the rotten core without interfering with the existing tabbing if that is a concern. That said, re-tabbing should not be a big deal, provided you grind the surface sufficiently to get to clean glass. The main bulkheads on the 34 are subject to tabbing failure, which on my previous boat resulted in the salon bulkhead walls shifting a bit (and messing with door alignment). We had no difficulty cleaning things up to re-tab. Never had a problem after that.

Pictures here: IMG_6750.JPG IMG_6747.JPG On Breakaweigh I discovered my forward bulkhead holding the chain plate for the headstay was constructed using a plywood core and had been modified over the years. Of course no one thought to isolate the core in there when drain holes were drilled and such and now the core material inside the bulkhead is nearly disintegrated or rotten. There is a front and back fiberglass layer, each about 1/4" thick and are well tabbed into the hull. This rot is making me damn nervous and my gut is telling me to cut into the exposed side, remove the rot, clean it up, sand, etc. and re-bed in something stronger than wood, then re-glass and re-tab it into the hull. Before I try anything like that I'm just wondering if cutting then re-glassing one side of these original hull tabs is a bad idea? will the new tabs be strong enough to support the re-inforced bulkhead? (using good quality glass and epoxy) Thanks guys, Dan Breakaweigh C&C44 Halifax, NS -------------------------------------------------------------------------------- _______________________________________________ Thanks everyone for supporting this list with your contributions.
