Bush - I don't know how durable or effective that would be ? I understand what you're describing, but sand, fish guts etc might make that set-up breakdown quick.

The silicone is still stuck to my tank hatch 36 years after it was installed! Of course I don't open it often, but I left the screws out so I can quickly open it to check for leaks around sending unit gasket after I fill the tank. I used some foam weatherstrip gasket around my cabin hatch and it didn't hold up that well, although it was some cheap stuff from HD. . maybe there is better stuff available now. I think the silicone would be a lot more durable as long as it sticks well. Maybe could create an additional secondary seal by adding a thin bead of Si around bottom lip of hatch after the stuff on the sides cures.
