The first answer is absolute rubbish ! The reasons are very simple -
Firstly, none of the passengers - and a lot of the crew - didn't know there had BEEN a collision with an iceberg. A surviving officer, who was in his bunk at the time, said he felt only a slight vibration.
The iceberg DIDN'T "cut a 180-foot gash in the hull", as was.thought for a long time - that was what was believed to have been needed to flood 3 compartments. The ship was turning away and "bumped" it sideways-on, which pushed in the turn of the bilges, buckling the plates, and "popping" the rivets. (If she had crashed into it bows-on, she wouldn't have sunk, because only 2 compartments would have flooded.)
When the passengers were told what had happened, and to go to their boat stations, the ship was still upright, with no sign of serious damage, and they believed that, in any case, she was "unsinkable".
In those circumstances, on a very cold night, many decided to stay aboard rather than get into the open boats. The officers couldn't force them to do so, and the boats had to be lowered right away, before the ship heeled to much, and so many left half-empty.
It has also been queried why, after the ship had sunk, the boats didn't pick up more of those in the water. Three reasons here, firstly, when launched, the boats would have pulled well away as far as posssible from the ship, to be clear of the enormous suction when she went down; secondly, there were very few men aboard them, and it takes at least 2 strong men to lift an inert body from the water, especially since the boats were quite high-sided - even more so because half-empty, and so picking them up would have been extremely difficult ; and thirdly, the water was so cold that those in it would have lost consciousness within a few minutes, and died within a few more.
I am only too well aware of this - we lost a small ship in our convoy - she capsized from stress of weather, not enemy action - in a North Atlantic gale with driving snow, and had the greatest difficulty in picking up any of the crew from the water in time. - it is an awful thing to see men die just a few feet away because your arms are too short. And of the 7 we did manage to pick up, only two survived, in spite of getting them into the warmth of the engine-room, and spending hours on resusicitation - they were just "too far gone".
