[PSUBS-MAILIST] Snorkel

[Alec Smyth via Personal_Submersibles]

The captain's objective I believe was to breathe outside air in the event
he surfaced into rough conditions in which he could not open the hatch.
This can be accomplished with a snorkel, but also with say an over-pressure
valve, a small pressure compensating ball valve, etc. So long as you have a
means of breathing outside air, I think you're good.

Best,

Alec
