Keep in mind that you might put the hatches onto a hot boat ashore, and then form a vacuum as the boat cools in the water. If it's a perfect seal, it could make it really tough to remove the hatch.

Anyone want to check the steam tables to see how much delta pressure for moist air going from 110 deg to 70 deg? It sounds like a large temp chng, but I think that's quite feasible.
