Thank you so very much Kybrt/Al for explain all this. I'm sure it was difficult to write about, but then I understand your personal need to do so. I think you and I exchanged some emails when you were trying to get registered for SB.
As I said a few posts back, the primary reason for this forum is so we can learn from the losses of others - not try to convict anyone of any wrong, especially based on partial hearsay evidence we may have to discuss. It may seem like we are at times - when we offer speculations about what may have gone wrong, what some individual may or may not have done, but that is not the intent here. It is purely for discussion so we can learn, human mistakes notwithstanding. Sometimes some of us may err or get carried away.
I spoke about this incident with my home buddy over dinner this evening, as I always feel especially responsible for his safety when we dive - explaining what I said above that we are adding to our surfacing routine on our next practice in a week or two. That is, I have always surfaced with my right hand up to wave and left hand on my BC hose - which I had been using to dump expanding air on ascent, then used immediately to fill the BC for flotation, or to dump again if I happen to see a jet ski or boat approaching.
I asked him what he's prepared to do if his BC fails to float him, and he gave me a puzzled look. I have had it happen, when my hose came loose, a nut came loose, and there are other possibilities - sand in the inflator button, etc. When it has happened to me, I orally inflated, but - panic did not control me then. It could another time. I explained (I get pretty pushy with him, we have it worked out) as soon as we have waved - ok or otherwise, then we will reach to grab a weight pocket. Should we ever need to dump weights, I want us to be in the habit of having our hand right hands already on the first one, as so many accidents and losses happen on the surface.
We are going to discuss this some more and run drills.
But back to your post, Kybrt. Thanks for explaining all you did about the boat. Sounds well equipped, and sounds like you all responded well. When a diver is around 450 ft away screaming, then only afloat for a short time, not much you could do, but you gave it a good try. Sorry to hear another diver was injured, but glad he recovered.
Actually your boat is better equipped than most I have been on, including my favorite North Carolina wreck diving boat, as you do have the kayak, albeit too small for you personally. Again, my condolences and commendations, to you too.
I'm sure you studied Critical Incident Stress when you took your Rescue course. It might be good to review the possible effects with others, and prepare to take possible action for your own benefit. PM or Email me if you would like to discuss this with me. No expert, but we can talk.
