Hi all,
Horrible accident, my thoughts go out to all who knew her.
From where I'm sitting, many thousands of miles away, it seems the captain may have made a grievous mistake, but that's up to authorities, lawyers and insurance companies and not up to me or -to me- this forum.
As far as I'm concerned, any diver doing stuff like this should use smbs, because a captain (of this boat and all other boats in the vicinity) isn't omniscient. If deploying the smb fails, there is a lot of other stuff divers should do like vertical ascent, leaving bubbles, hovering 10-15' below the surface to make sure everything is safe, etc. The problem with that is the fact that things can -and will go wrong- equipment failure, panic, dumb mistake, etc. that may cause divers to act unexpectedly, like surfacing too near/under a boat, too fast, you get me. Any captain should always take that into account.
This is probably where the inherent risk of the trade comes in. Generally, I would advocate against operating the engine with divers being within 300' of a boat in any direction. Ever. But with dives in less than absolute perfect conditions, that may leave divers unable to reach the boat which is also quite an issue. In a perfect world I would advocate using non-lethal means of propulsion near divers but I know too little about boating to know if that is an option.
From this accident, my lesson learned is to be more cautious around boats with a running engine and to start to always take along an smb with every dive and practice using it more (I mostly do shore dives in a lake without any boats around, but not exclusively).
I'm curious how you all feel about the issue of operating a boat anywhere near people in the water.
