With no disagreement about this entire post, and accepting ALL the lapses that were allowed by the direct participants in this disaster, I still have one question.
In what universe is it acceptable (read: within standards) to take a student on for "Advanced Open Water" certification with five or six dives, the fifth being a year ago? This diver was certified as an OWD, but did not have the awareness to call her own dive
- with impending darkness
- with no light
- in a drysuit with no inflator hose (had she read nothing?)
- with apparently little or no dive briefing
- without the wherewithal to release her weight pockets (assuming that what was zipped was actually her weight pockets with half her weight)
- grossly overweighted
So even assuming that we completely overlook the Instructor's clear culpability in this scenario, if this poor diver wasn't incredibly stupid, she was too inexperienced to undertake this certification. And that's on the organization that allows this sort of thing.
Yes, you can point to the dive shop and Instructor who appear to clearly be at fault. But (even assuming a light, a briefing, a hose on your new drysuit, a quick pool checkout in advance, and 44# of ditchable weight) would YOU go get AOW certified in a cold lake in a new drysuit for the first time as an OWD at night with five or six dives, most of which were a year ago? Who allows naive divers to think this is okay, even WITH all the boxes being checked!?
Yeah, I'm on a dive organization rant, and I think it should be harder to earn your credentials, if that wasn't already apparent. The pressure Instructors are under is a direct result of dive shops trying to stay alive, actively abetted by training organizations who make the public believe you can become a scuba diver over a three day weekend. That is wrong.
