Thats absolutely fix-able.

Dave,
How about making a collar for the daggerboard trunk. Can you get the bottom half out of the hull? If you can get the bottom half out, make a sleeve and then slide it back up onto the top half. Then glue the bottom part of the trunk back down to the hull.

The only tricky part is going to be getting some reinforcement on the inside of the bottom of the hull.

Think about using wire to pull everthing back into shape once its glued. And creating some internal backing structure that you can sandwich some glass in between the broken parts and the solid parts on the inside.

I'm trying to figure out if you could pull it all back together without cutting lots of big holes in the boat.
