Hi I was thinking about hidden hatch hold downs.
Two Bungy cords mounted to the under side of the deck, parallel to the beam, at the front and back of each hatch which hook over hooks glued to the bottom side of the hatch cover to hold it down. The only thing sticking up would be a knob or some other handle to lift the hatch. I think I saw them once some ware on line and was wondering if any body had tried this. Point of doing this is to keep the deck as clean as possible. . . Yes I would still have deck ringing for safety and gear storage etc.
