O'Day's advice on adding #... and weighted C/B's
Darren: I have a copy of the original O'Day manual, and they said that you can add up to 200 pounds of lead, in the form of lead shot, into the bilge pump hole so it sits directly on top of the keel (on the stub keel boats). They also say that you can pour epoxy or poly resin in to hold it in place, IF it is all dry down there. If O'Day OK's it, I'd trust the advice. I am happy with my original 600#, however... I never felt the boat is tender, as others have. As for the other question on the centerboard not sinking, I agree that there would be nothing wrong with adding a "plug" of lead to make it sink. I built a 20' cruising boat with centerboard, and the plans called for 35 pounds of lead inserted to sink it. This worked out to a rectangular section about 5x9", and 1 1/2" thick. I poured it in our wooden board, but I would not do that with the fiberglass board, of course (assuming they did not replace it with wood). But you could cut out a section, insert lead mixed with some resin, and glass it in from both sides. But if the board is wood, and you do pour, remember to put screws into the sides of the hole to secure the lead when it pours around it. Mine has stayed that way for 10 years now. Rich.
