Respectfully speaking the water must have a way in. I see countless boats pick up at any given ramp, the owners walk to the transom, and pull their plugs and gallons of water runs out and not think a thought about how it got there or care. Not a drop is supposed to run out unless you got caught in a rain storm. Sprint grade boats like Blazers of the day, Champions too, none had the waterproofing internally just externally. Now take a Cobalt, their bilges are a pretty as the rest of the hull. Gelcoating your bilge in a build like Slab is doing is critical in preventing moisture migration to the foam. Also if you pick up your boat and have water in the bilge fix the leak. A notorious place for a boat to put water directly on top of the foam, The Rub Rail Seam! More Rub Rails Seams leak that owners could ever imagine and the water goes right on top of the foam. Condensation plays a part too, why I keep all my fiberglass boats inside when not in use.
