Not sure if this counts as a near miss as I don't think there was any real danger, but will leave it to moderators to move as they see fit.
This was on the first dive of a liveaboard and I had most of my own gear, including a new bcd - zeagle zena. The bcd features a ripcord, one hand weight release. Pulling the red handle will release weights from both pockets. The weight release handle is secured and I don't think a diver would pull it by accident.
I put two weights in the weight pockets and two in trim pockets, which are not ditchable. This should have been enough for a slow descent and neutral buoyancy on ss with 50 bar. I checked my gear before going in. I did have to get out of the bc to get into the tender as i wasn't confident of doing it with the 12l tank, which is way too big on me and put the gear on again in the tender. Once in the water, I had some trouble descending. Suspect this was due to it being the first dive, my gear all being dry, etc.
The dm swam up to me and offered me two weights and proceeded to fiddle with my weight pockets to put them in. I descended slowly, very slowly considering the amount of weight, but then had some pretty bad buoyancy issues during the dive. I was too bouyant once we got to shallow water and then just could not hold the safety stop. The dm gave me one more weight to hold, but even so I kept floating up. At this stage I was supposed to be carrying 5.6kg of lead, which is almost twice what I need, so this was very weird.
It was such a struggle that I terminated the ss after a couple of minutes and ascended early (it was a shallow dive, first dive of the day and I was on nitrox with heaps of ndl time on conservative algorithm, so I figured the risk was minimal).
Once back on the boat, I found that my ripcord had been pulled (although incompletely), so I lost all the weights from my pockets, except the two I had in trim pockets. Buoyancy problem explained! The lost weights were found at the point where we started the dive.
I suspect that what happened was that dm pulled the ripcord, thinking that this is the way to remove the weight pocket to put in extra weights. I think some bcs have that system. I asked him and he says he didn't, but I can't figure how it could have happened otherwise. I wasn't angry with him at all, I should have told him about the unusual weight release system beforehand.
I explained to the dm how the weight release worked and rethreded the pockets (only took about 3 minutes). No problems with the system for the rest of the trip.
Learning from this: tell the dm as well as the buddy how the weight system works and to not pull the big red thing except to drop weights!
