Hull Damage and repair C22

[Simon]

Hi all:Thanks to Ted for your suggestion on the keel cradle it worked like a charm. I have the keel off and ready for refinishing. My topic today is my '71 C22 750 model hull has some damage due to having sat on the trailer bunks without proper alingment and the weight of accumulated water caused a "warping" on the starboard side along the length of the supporting bulk "stringer". On the inside it is as if some stitches pulled loose on a wound and on the outside there is an indented area about a yard long. The hull was compromised with a 8 inch crack. On the inside I plan to place a supporting bulkhead "wall" of 3/4 inch marine plywood wedged under pressure using a jack. Then fiberglassing the hell out of it. Then use thin cloth fiberglas on the outside and sand smooth and paint. What do you all think? All your comments and suggestions will be appreciated.Simon

A few comments . . .

overall your approach with an additional bulkhead should work. The bulkhead will apply reverse bending to the hull, and hopefull get it back close to original. The only thing that I would do differently, is to use epoxy and glass filler (mixed) on the outside of the hull rather than fiberglass. Put the fiberglass on the inside of the hull. The difficulty with adding fiberglass to existing fiberglass is adhesion. You will get better adhesion on the inside. Plus you can rough up the interior surface with sand paper.You'll need to sand the repair area on the outside as well, prior to applying epoxy/glass. The epoxy has better adhesion qualities than fiberglass resin, and it is more water resistant.Sounds like you are having some fun.Regards,TedP.S. I assume that when you say "1971 C22 750 Model", you actually mean C22, hull #750, which was built in 1971.
