Hi everyone,

I am curious if anyone out there has flush mounted hatches which are waterproof (incl. rolling). I looked at all the options I could find and there are only two which seemed to turn out at the end.

Assumptions:
~2 lb of force per bungee (four in total) for sealing. I presume that I may need sone additional force to force the hatch into the proper position.

In case of Joe's designs the gives you 1/32"
