I'm trying to find the source of a leak in my 2008 21SE. I've owned the boat for two years and every time I run it off shore for a few hours fishing there's always a gallon or two of seawater in the bilge. As part of my post trip maintenance I always sponge out the water so I'm starting each trip with a dry bilge so I know I'm not leaking at the slip. I pulled my boat yesterday for the season and looked over everything (through hulls etc) and can't see anything obvious that could be leaking. I'm wondering if when I'm underway and up on plane, if water is being forced through the rub rail and between the bolt on area between the deck and the hull? Has anyone else had this problem and if so, how did you fix it?
