I am interested in replacing the hatch because it is a poor quality hatch (I believe that it is a Forespar product). The existing hatch needs new plexiglass, a new gasket, a new screen, and also leaks around the perimeter in addition to the gasket. I recently sat out a storm inside the boat and was able to observe all of the leaks. I can attempt to remove it and rebed the hatch but if it should break (since that it is plastic), then I would have to locate a replacement that will fit. I have heard that some hatches do not seat properly in the later Oday boats because there is a slight curvature in the deck (although I have not checked mine with a straight edge).
