Thanks, folks, I'm getting a picture of Cozumel's operating environment, where it seems many people don't actually set out from the dive shop's own premises but rather are picked up from several different locations. I can appreciate that this constrains things in a way I hadn't considered. Storage is only one consideration for us.
Also important is an intelligent solution to varying air consumption in the group. Going up to the boat at different times was what I imagined to be the best way. If that's too hard in a strong current and the dive op wants everyone to surface together, one PM suggested that DMs would be open to air-sharing with the air hog. Um? Only has happened once outside training, and I was frankly alarmed when the DM handed buddy his octopus in order to let us keep watching the lovely schooling jacks. While we don't like pissing off fellow clients, we would need more advice before deciding that air-sharing outside of emergencies is in our comfort zone.
