I have no idea what that scenario means. How does the buoyancy work? How did it not capsize when there was no one on it? You're loading people above the waterline, to be on/off in a minute, so that makes it more likely to capsize, not less. How come the people off the ship can't help the people in the water? And so on, and so on.
If a rigid airship is being blown about, and might be unmoored, a trained ground crew will jump on the lines because with enough weight they can save the ship and its crew. If too few grab a line, it will unmoor. If you are on the ground crew, and you let go of the line because you are worried about your own life, are you complicit in the deaths caused by the ensuing airship crash?
