I recently did some diving on Australia's GBR. First time ever on a dive boat setup for 50 divers or more. Definitely not my style of diving. Max bottom time 40 minutes. Dive 1-2 surface interval only 10 minutes.
It seems ive been well spoiled diving in the pacific with max numbers 14 per boat.
So what is the normal scenario around the world ?
Must be 14 - 21 pax per boat as what we are doing here in Maldives
