i read the accounts of those involved, and tried to put myself in the shoes of the dive guide because i'm positive this is going to happen to me one of these days when i lead some divers on a trip.
here's my 'analysis' and conclusion:
facts
1. i have 3 divers around the other side of the coral formation in a strong current.
2. i have another diver with me
3. all 4 divers are pretty deep, and cannot hang around for 15 minutes without aborting the dive.
4. i have another diver who just went up to the boat and didn't come back.
the logical thing i'd do is to quickly pop back up the boat (i hate see-saw profiles!), check if the lady is at the boat. but i'd really want all 4 divers in the water to be together, so i send the guy to join the other 3 ladies first before i head up to the boat.
when i get up to the boat, the boat man says "yeah she came up, then went back down to look for you guys."
now, i didn't see the lady on my way up, so i have no idea where she went. assuming there was a dive briefing and she knew the dive plan and general direction, she could have carried on the dive. i still have 4 divers down at 80 ft in a strong current. my panties are starting to feel a little twisted here. so i tell the boat guy to keep an eye out for the missing lady, i'm going to get my 4 divers in the water and maybe carry on with the dive and see if i can find her along the way.
i descend again and catch the other 4 divers still waiting there and see no sign of the missing lady. it's big blue ocean, with a wall on one side. maybe she's just further up the wall? or could she have given up and gone back to the boat? urgh :glare:
so i have 2 options now, carry on the dive and see if she's ahead, or abort the dive and hope the lady's on the boat. if i abort the dive and she's not on the boat, i can't call search and rescue yet because it's only 10 minutes. plus these 4 (maybe 3, cos the husband is going to be worried) customers are going to be pissed at me if i say we all surface, so let's just see if she's further along the wall. in any case, i don't know where to search for her because i haven't seen her at all when i went up and down the line, and the boatman's watching out on the surface.
so yup, chances are i'd carry on the dive. but then again, if it were a strong current, i'd go with the current or abort the dive right from the start and try someplace else. but i guess this wasn't an option you had at that particular site.
to be fair, i would have gone up together with the lady and her camera, after getting the 4 divers in the water together. if it were not possible, then let the 3 who had gone on ahead to wait, and gone up with the man and the lady instead of sending the man to join the other 3.
i'm not saying it's anyone's fault, more like a series of unfortunate events and miscommunication made worse by not following safe community standards (surfacing without the buddy, going back down alone when unsure of the dive site).
i'm glad you guys came back safe! and thanks for providing this classroom learning activity for me to think it through.
