He who owns the boat gets to make the rules, and for most deck hands it is just easier to look at the pressure rather than attempt to convert that into cubic feet. It might help if you found some off time to walk the objecting party through the math and show them that it is the cuft that matters more than the psi, then again it might have the opposite effect. I just let the owners make their rules and if I can live with those rules I patronize their business and do the dives. If the rules seem to silly to deal with, I look elsewhere.
