Similar thing taught for offshor survival training in the north sea.

If you give up you are a gonner if you dont you may make it, and everyone who has survived had a determination to struggle on even when it looked bleak (i think the stats say something like if you are not out of the water in 5 mins you are unlikely to survive - even with a survival suit.)

They show videos of people passing out as they are airlifted out of the sea too and falling out of the sling. or passing out and drowning when they see the helicopter overhead - assuming that they dont need to fight any more.

Obviously take those statistics with a grain of salt.

According to some stats you can survive one minute in icy water.

Yet many people enjoy swimming in the ice, including some who can stay in the icy water for 15 minutes or more just for kicks.

I imagine these stats have a lot more to do with the roughness of the water than the temperature. Rough water can be extremely difficult and stressful to stay up in, especially if you're not used to it.

Also, if you get tossed off a boat in the North Sea, chances are that the water is not very calm.

It can depend on the individual, too. There's an interesting book called Swimming to Antarctica, which is a memoir by Lynne Cox, an incredible long-distance swimmer who discovered she had a talent for cold water and who (after extensive preparation) swam five miles in sub-40º water.

Thanks! I didn't know of Lynne Cox until you mentioned her.

I don't mean this unkindly, but I notice in the photos that she was a bit heavy. Was that considered a factor in her ability to withstand the cold?

In interviews she refers to her fat as "blubber." [1]

She's a fantastic writer too, I found this piece she wrote from the New Yorker, definitely worth a read[2]

To die within one minute means the cold shock killed you, not hypothermia: https://gcaptain.com/cold_water/

One of the exceptions shown was a guy who was asleep below deck when his fishing boat sank. Iirc he treaded water for a while as all crew mates succumbed one by one. He then swam to shore (miles i think) then walked several more miles to a house.

I think he collapsed on the doorstep (again having "made it") but was okay in the end.

He was not a slim guy, not sure if that helped.. but it was one of the dont give up examples. So outcomes do vary wildly.

Reminds me of the documentary film Last Breath, telling the story of deep sea diver Chris Lemons.

Maybe the documentary tells more, but I just read a bbc piece on him and it seems like he gave up:

> He remembered: "I think once I accepted there was no hope of survival, I was powerless to do anything to save myself. A quiet resignation came over me."

In that case it seems giving up instead of panicking might save what precious little oxygen you have left.
