There is another version: the captain must go down with the ship. I seem to recall this was practiced in certain navies way back when. Does anyone know the details?

I hope the more draconian version doesn't apply to us recreational boaters. Man, I'd hate to go down with my Sunfish.

On another note, I am sure there are many Italian men and women who will rise up to equanimity and courage in the face of panic and catastrophe. Just not Schettino.
