LOL. That's quite honourable. But would you not consider how the ones who love you will feel if you disappear? I know you wouldn't be around to see that in this scenario, but still.

I would. But I would also keep in mind the loved ones of all those around me, and how they would feel if their loved one didn't make it home.

Damn! You, sir, are a great person.

It would be morally praiseworthy but not morally obligatory. That said, I have an old-fashioned sense of honour. I would help everyone else I could before stepping off myself, starting with the women and children.

If you have the intelligence to fend for yourself, you should.

The classic example, of course, is the Titanic, but what most people forget was that there was almost two hours between the launching of the first lifeboats and the actual sinking. Basically, by the time you know the ship is sinking and that there are not enough lifeboats, you have an hour left.

An hour of free reign of the ship? I'm sure I could come up with something to keep myself alive. Possibly someone else, too. I expect this of myself.

Sinking in five minutes with an arsoned fire onboard? That's not so likely.

I admire your mercy.  The world is better with attitudes like yours.

If I'm not mistaken, what killed more people during the Titanic sinking were the fact that the lower classes had the "doors" closed and not all could escape in time and the fact that those who fall into the water (even the ones with life-jackets) died because of hypothermia.

A men can't give birth so yeah but i'm not sure about who should go first.

hm.. the main threat in that case probably is hypothermia which theoretically means women have a better chance to survive in the water as female skin has a thicker layer of fat beneath it, which means that their bodies don't cool off as quickly

in ice cold water (Titanic) conditions that should only give them some few more minutes, however in "cool" water (15-20°C) there might be a significant difference in how long they can resist hypothermia

Not sure about ships, but when you go rafting and by unhappy accident the boat is upside-down -- the thumb rule is to save men first, those in turn save everyone else because they are better at that.
