Jumping in here, although I have a C&C 33 MkII my hatch leaks as well but it seems to leak between the teak rail and the cabin roof. I'm going to silicon the joint from under the cover. Is there supposed to be a drain to let the water out from under the cover somewhere? I see a reference to "limber holes" in the original post. Mine was siliconed down very tightly and full of black mould and mud. I thought I would use butyl tape instead, where should I leave a gap? Incidentally there is a 1/2 by 1/2 strip of teak on the outer, underside edge of the plexiglass sliding hatch to keep it in line, and another on the inside back edge to stop it from pulling out. There is also a stop screwed to the cabin roof to prevent the hatch from sliding far enough in to pinch fingers between the underside of the hatch and the front edge of the opening.
