The first incident was in 2004. There were different protocols then. In that case a shop chartered the boat. They supplied their own DM and the only crew on board was the captain. This was fairly common back then. And yes, right or wrong the roll call and duties were delegated to the shop DM. After this incident that practice stopped on the Sundiver boats for obvious reasons. No one ever relieved the captain (again, it was not Kyaa) of his responsibility and they faced the full set of consequences. The situation on this most recent event were completely different (albeit with a similar result), and again, the captain is dealing with the repercussions.How did that work out? And why was the Captain - the individual that was always responsible - abrogating responsibility in favor of a passenger in the first place?
If you have never been on the boats you can envision what you consider a culture of lax systems and procedures. Based on the times I dove with them I can tell you that is not the case. Yes, there were exceptions, but to me they were not an unsafe operation.
No one, including me, wants to think of a diver being left at a site. And I do not see anyone trying to justify it, only explain the circumstances. There have been plenty of divers left at sites, by boats that still operate under the same captains, but they didn't have the notoriety, and fortunately did not have a fatality. They retrieved the divers and nothing was said. If the consensus is that any boat that leaves a diver should be out of business, then we have a lot of work to do. Again, I'm not justifying what happened, but think we are fooling ourselves if we think this was a unique situation.
