Another thing- the cockpit floor in mine has 1/2" holes drilled in the corners draining to the bilge. I suspect that is endangering the balsa core, but it might be solid fiberglass in the very corners. I was planning on boring these out and instaling 1" PVC bonded in with epoxy or plexus. These 4 corner scuppers could drain to the bilge or could feed a small sump with its own bilge pump that sits atop the keel stringer.
The idea is to have adequate drainage to keep the cabin itself dry(ish). And to pump the water that gets there past a hard top and windshield overboard before it has to run all the way aft under a few bulkheads to get to a bilge pump.
Any thoughts? Especially with PVC scuppers/drains from topside to the bilge (not thru). I am not sure how strong a plexus or epoxy bonded in PVC pipe would be. I would slightly recess it below the deck height, but even so, I am concerned.
