Sorry for yet another dumb question. It rained the last couple of nights in my part of the country, and each time it rains I get water in the hull to the point where I will raise the nose up on the trailer and a few gallons of water will come out of the drain hole. It even gets high enough for the bilge pump to suck it out. Any ideas on how it's getting in there? Yes it's covered but the cover is just about useless. (I'll order one from that poppy place pretty soon).
