From what I remember, the sea water was something like 25 F which can kill a person in 15 minutes, so I can’t see how anyone survived who was thrown in the water or jumped unless they were immediately picked up.
That’s my thought also. There was also the lifeboat that lost their oars — it was found a month later with 3 dead bodies on it.

29 F
From what I’ve heard (like it makes any difference)
Then there’s the drunk bread-baker on the Titanic....
