Number of crew members = how much air
 

Does number of crew members influences the time underwater?

A good question. Let me begin by saying I don't have a clue.

All I do know is that I'm now wondering if oxygen levels decrease slower if you put the crew to bed as they should breathe less....

Dear oh dear...

Interesting thought. Somehow I doubt it.

Maybe I'll try some test dives with my next career just for fun.:hmmm:

The answer is, unfortunately, NO.

It should, but it doesn't make any difference.
