I was working on a longliner in AK, and we had just unloaded a 16-day catch of blackcod. I was climbing out of the slush-brine tank, dead tired, with full gloves on, hit the lip and popped from 12 feet.
I remember looking back and seeing the circulation pipes (3") set a good 2" off the bottom of the hold, and my lower back was on a serious crash course to one of the metal supports that held the pipe. I couldn't change direction, so with every ounce of power I had, I twisted. I had about 3 seconds.
The pipe hit me inches above the hip on my right side as I collapsed (hitting my head badly), and I relaxed, knowing it was my only hope.
I had a bad bruise above my hip but was fine otherwise, but I will never forget the moment of relaxed impact.
