Jake,
You could put a watertight bulkhead between the main beam and centrecase that you can get to from an inspection port behind the main beam. (That is provided your boat has an inspection port behind the main beam.)
This bulkhead can then have a bung in the bottom of it and
normal hatch port in the top. This would allow any water entering the hull forward to drain to the rear by releasing the bung and when the boat is not being sailed you can undo the hatch to allow normal air circulation in the hull.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
