So we had a fun time Saturday in high winds. My son and I hit 17 knots on the GPS.
A bit later we had 3 of us on the boat, and apparently 200 pounds of water in the starboard hull! This became apparent when we were slowly tacking back to the shore, and we nearly rolled the boat over backwards! We hauled it out, pulled the plug and it drained a very high volume of water for a very long time.
After close examination, I found a gap under the lip of the deck/hull joint, under the tramp, halfway down the hull. Several gaps actually, the biggest about an inch long and 1/4" wide. Air easily flows through this gap (and thus water, when under a heavy load..)
Yesterday I routed it out with the Dremel and filled it with thickened epoxy - should be good. By all appearances, the gap has been there since day 1 (which was 35 years ago). This boat was very lightly used during those years, and it seems we are shaking out defects that should have been taken care of long ago.
If any of youze with more experience in this particular defect would like to comment, please do so!
Anyway - here is what it looks like with a heavy load of people and water in high winds. You can see that starboard hull is pretty loaded! she really starts to boogie around 25 seconds in....
