Tom, Your post has a lot of assumption, speculation, and crystal ball in it:
Of course. I put myself in their place.
"That sounds about right...", "The diver did...", "...watch him drown?", "...there was a 60 second window of opportunity to get to the guy.", "It's entirely possible...", "For all I know...", "...nothing got done...", etc...
Yet, you are so quick to condemn the boat crew, even though none of the information in this thread is an actual account of what really happened.
Well, from what I read, no one got wet trying to get the guy. Just motoring the boat over just was not going to cut it. Does that sound like condemnation? Yeah, kinda. I drove boats for a long time, been on a lot of different boats, and seen every type of captain out there. You're a pilot - after a while, you know what pilots have the right stuff and which pilots you'd prefer not to have the stick with you onboard.
What if the investigation identifies an OOA at depth and a subsequent rapid ascent to the surface causing an embolism?
Entirely possible, and not a damn thing anyone could do. It still tears up the crew even when they do everything possible. I thought I had mentioned this possibility in the middle of my ramble anyway. It sure would help appearances though if they had attempted to get the guy before he sank.
Even if the guy was dead, better the boat should bear him back to port than someone else have to get them.
What if the diver makes it to the surface in really bad shape, but without any real witts to do the right things to stay bouyant? ie drop weights, orally inflate, properly communicate with waiving arms that there is a problem
Well, the diving professional in the boat saw the guy on the surface in extremis. And from everything I've seen, not a whole lot was done to effect any kind of rescue. What's arguable there?
If the captain could not do anything in a given timeframe - lack of conditioning let's say, well something's wrong with that operation. It's a fact that there are some strong currents out there. Emergency plans-of-action sometimes come in handy.
Yeppers - not to be too cold, but we're here, and the diver is not.
Why point fingers in this thread at anyone right now, before an actually diagnosis of the events is revealed?
I'm just pointing out the inadequacies of the crew response to the situation. They saw the guy, yelled to the guy, and watched the guy disappear. It's not like they were on one end of the 510' Spiegel Grove and saw this tiny little wiggling dot at the other end of the wreck - it sounds like the guy was next ball over.
If you are wrong, you've done an injustice to that operation.
I'm not blaming the captain for the guy's death - for whatever reason is the determinate cause-of-death, the diver assumed a certain amount of risk undertaking a dive on the Spiegel Grove.
Now if it turns out that the captain launched a rescue board but couldn't reach the diver in time before he sank or swim the diver down but couldn't get there in time, I'll congratulate the captain on his valiant efforts.
Wear the shoes and see if you'd enjoy the types of posts being thrown out here with a total disregard for what may have actually happened.
As long as they spell my name right...
