Regarding Dennis’ comment about overbored holes being hidden by the track, a trick I like to use is to drill up from underneath and stop when the bit encounters the underside of the deck. The result is that the hole on the deck surface stays the same size. In addition, you know precisely where to place the deck fitting and drill the new hole.

Cut away the headliner so the backing plate is against the underside of the deck. I've seen too many folks simply crush the headliner against the underdecking. 2. Make sure the backing plate(s) is adequately thick and wide. If not, the loads will pull the plate into the underdeck and the track will loosen then leak. 3. Use a BIG overbore and fill. I recommend a fairly large overbore and fill. Normally, for a deck fitting, I would overbore 1 or 2 drill bit sizes. For a genoa or jib track, I would drill a fairly big hole that would still be hidden by the track. A plug of thickened epoxy will handle much more compression loading than a cored deck. So you can really tighten down the fasteners. Tighten them snugly then come back 24 hours later and really tighten them! -- Dennis C.

You will add many sources of leaks with the tracks--been there and done that. I would try a ring solution first--no holes required. If it doesn't work like you prefer, then get out the drill and butyl tape! Charlie Nelson Water Phantom 1995 C&C XL/kcb
