Hi all. I have a Hunter Xcite that fills with water after an hour or so in the lake. The only place where there could be a leaking seam is the seam where the top and bottom of the hull are joined in the well of the centerboard. Or perhaps there is a leak where the centerboard mounts to the boat inside the well. I can't get in to see without taking the centerboard off the boat. Does anyone know how to do this???
