Here we go again! I have a 2013 Oceanis 37 with a fixed port light under a deck cap. I have deconstructed the boat and have removed the port light, but am concerned that the deck surface at the aft of the port is not rigid enough not to flex/sag and thus break the sealant loose again. Thinking about putting some through bolts on the perimeter to help hold deck and port light together. Then I could use butyl tape! Anybody else run into this issue with a 37?
