I'll bet dimes to nickels that your problem is at the bottom of the well. Poke around and see if you can find the hole - mine was in the front center. Drill it out with a very small diameter bit and either squirt some epoxy in there, or just work in some marine tex. You'll never have the problem again.

A little bird told me that the issue derived from the joining of the hulls - there is a "[" shaped channel in one side that a tab inserts into from the other. There were a very few boats in which that joint would leave a tiny channel - once the board wears through the gel coat, it is a leak. The up-side is that it is very easy to find and repair, and the fix is pretty much permanent. The production issue has already been addressed.
