TNHYBRID, (I promise this is my last long question for the weekend) I am going to agree with you 100 percent about the "dive community" being responsive to tragedies. These are adventurous individuals who are already doing something I could NEVER do! They are strong, fit & gone through lots of training in less than ideal conditions. Sooooo, If they (the group/dive organizer etc)If I had to guess, many dive operations are making changes to charging of items on board as we speak - as in, strict language about what can be plugged in where, and even removal of electrical ports in spots other than those easy to monitor. Probably everyone will be required to unplug overnight. MOO but generally the dive community is pretty responsible and responsive to tragedies like this one.
had been aware there was no one assigned as a night watch.... wouldn't they willingly volunteer to lose a couple hours of sleep to help cover the shortfall? I am thinking along the lines of "don't dive alone" as a precursor to having two people volunteer to stay awake at a time, thereby lessening the chance of one falling asleep. Just thinking out loud: And wondering if that might be a viable, "volunteer-type" set up organized by the dive manager, when you have large groups??
Oh, and you mentioned you have been on "liveaboard" diving boats....in your opinion, would it be an option for a fireproof door, one that can be closed quickly to stop the smoke from spilling into the sleeping areas below deck be another possible change??
