Greg, On an ambient design , assuming
that your hatch is on top, you would need to have a good seal or you would start
leaking out air and water would start rising from the bottom. If you had
two hatches, one on the bottom and one on the top, you would have to be careful
to close your bottom hatch if you were on the surface with the top hatch
open. Have you decided how you are going to seal/paint the steel
parts of your sub? It seams to me that one would not want to paint
the hatch ring. Is there an oil that could be periodically applied to
the hatch ring to keep the rust at bay?

I too have a question
about a seal. In regards to an
ambient design, does one use a gasket (rubber / weatherstripping, etc) to
maintain a seal?
Thanks-
Greg

Hi
All, I'm in the middle of a hatch design and I'm not clear on
whether or not the hatch rings (where the hatch seals to the boat) needs to be
stainless steel or not? Could someone enlighten me on this.
Thanks
