I'll take a cracked boat over a cracked airliner any day. You can't swim away from a falling airliner.

Unfortunately the Liberty ships usually broke apart in the North Atlantic winter.

I've seen pictures of an empty oil barge that split (at the dock, in calm water, just very cold) because a small mast was welded to the deck plating incorrectly, allowing a crack to propagate. If anyone is interested, you do NOT weld a mast to a deck around a corner of its base plate, just do not do it.

I get your point. Two lost off coast of Pass a Grille a few days back and the water was a lot warmer and the boat didn't sink. Alcohol played a roll.
