This action is not an individual shortcoming, but a breakdown of command responsibility top to bottom.
Couple of things:
1. I see four scenarios where this watchstander could have fallen asleep and each one IMHO carries a different moral & legal weight:
A. Watchstander is doing duty but is exhausted (remember they usually work a day shift as well onb dive boats - maybe that's part of the problem), sit down to rest in the wheelhouse and dozes off unintentionally.
B. Watchstander has been ordered to stand watch by captain and after all others are asleep says screw this and deliberately abandons duty and goes to bed.
C. Captain assigns watchstander duty as paper trail only and watchstander goes to sleep with captain's full knowledge and approval.
D. Same scenario as C but Conception owner is well aware of this practice and does not object so it's SOP for the boat.
We don't know which of these four applies in this case. We should also remember that there's still testimony - this doesn't excuse the sleeping - of a crew member going through the galley around 2:35AM and all is well. At 3:14AM everything's on fire. 39 minutes. Not that the boat's very big but you could have been on watch, gone down into the engine room (accessed through a sliding horizontal door in the middle of the dive deck - and which apparently wasn't initially on fire) to do some stuff and come up half an hour later to make another watch sweep only to find a raging inferno.
And finally to the captain's responsibilities . . .
Supposes the scenario is A or even B. How is the captain supposed to police this? The only way IMHO is for the captain to stay up all night watching the watchstander. If that's the case, besides saying that that standard of care now has to be that the captain gets no sleep at all (and ignoring the safety issues that creates) if the captain needs to watch the watchstander, why not just have the captain be the watchstander?
Point is there's no perfect system and if the captain has given an order that isn't followed, what else could he possibly have done?
I was involved (defense expert) in a famous case (Drifting Dan) years ago where one of the allegations was that the captain is always responsible for anything/everything that happens or doesn't happen on the boat. In depo, I challenged that notion and said prove it. Show us the CFR. No one did. Our attorneys did not want to make an issue of it at trial (big mistake IMHO) but the bottom line is - and I'm happy to have someone here show me I'm wrong - no one was able to locate anything in the CFRs that specifically assigns the captain all blame for all things. (The extreme example was that a fight breaks out in the galley and one passengers pick sup a knife and murders another passenger. Does the captain also go on trial for murder because if he's responsible for everything, he should. Same thought applies to if it's a crew member doing the murdering. Where do you draw the line here?)
