I have a 2003 hull that is getting a small amount of water in it only after sailing in pretty heavy chop. That tells me that it is probably coming in somewhere in the bow. It's not the mast step though. But the baffling part of the leak is that the hull holds air. When I remove the drain plug after sailing it blows air out from the pressure build up. A lot of air every time. So how and where can water get in the hull if air cannot get out?
