Successful Float Test!

... on Typo Lake.  The dagger board trunk is finally not bleeding water from the corners.  Read something on one of the wooden boat forums about using pressure (think they recommended a blow dryer) to cram caulk or resin up into a leak.  After sanding down with a shim covered in paper towels and sandpaper, I applied 3M 5800 caulk liberally both around the outside of the bedlogs as well as the inside of the trunk/seam of the hull and bedlogs/anywhere that looked like it could leak.

I then applied a duct tape patch to the daggerboard socket at the bottom of the boat and the top of the trunk, leaving just enough room for a duct tape-wrapped tube, which I connected to a shop vac.  I threw the shop vac on reverse, and while there were a few leaks allowing the air to get out (which I wanted... didn't want to generate enough pressure to do damage,) I believe it also created enough pressure to force the caulk up into the leaks.

Typo Lake is down, by the way.  Way down.  Damn this drought.
