Really? What mistakes were made by the diver? I'd like to know, because I've been following this case for years, and I cannot see one thing the diver did wrong. So, let's hear it: what'd he do wrong?
I usually stay out of this discussion because I (used to) dive the Sundiver quite a lot and consider Capt. Ray to be one of the best capts around, and intend to dive off that boat again once I am diving again. I actually dove that boat the week after Dan went drifting
First, there is NO QUESTION that there was a HUGE screw up. Marking him on and off the boat? That's bad no matter how you shake it out. I *heard* but have never confirmed that someone answered for him by mistake after the first dive, then answered again for themselves, and never told the DM. True? No idea. That doesn't explain the second dive though....
The real legal issue is WHO is responsible for that? Clearly the DM, clearly his or her employer. The charter? That was a big issue, and it was I guess a lesson learned that the capt's responsibility isn't just to find a good dive site, but to manage divers as well. Actually, the story doesn't say against whom the judgment was awarded, as there were several defendants, including the shop and the boat. Either the damages were apportioned or it was "joint and several" liability, in other words, any one of several defendants is responsible for all of Dan's damages.
I never dove the Sundiver as a shop charter, I only dove it as a Sundiver charter, and as I recall they always did a visual roll call.
As for what Dan did, well apparently the jury agreed that Dan was partly at fault, as the original award was $2 Million, reduced to take Dan's own negligence into account. Looks like the jury determined that Dan was 15-20% at fault.
As for what he did, at the rigs I can think of a couple things. One, don't lose your buddy, and if you do, surface immediately. If you don't find the rigs in a couple minutes (they drop you off away from the rig and you swim to it), surface immediately. He did neither of these. If he had, he might have avoided it all. Carry a large marker and whistle (not sure if he did, or whistled, or inflated a buoy), swim to the boat if you are on the surface. There's a lot that he could have done wrong. And anyone that determines liability or lack of liability based on a newspaper article does not have all of the facts (in fact, unless you were sitting in trial and heard the testimony we don't know the full story)
