Not quite the same, but if you were interested in this story you might be interested in reading "Last Man Off" by Matt Lewis. It's the story of how he survived a fishing boat sinking in the Antarctic. Basically came down to luck and having donned the appropriate survival suit, but very much touch and go and many of his fellow crew members didn't make it.

For full disclosure he's a friend of mine, but the book is a gripping read.

OK 75 is a lot, but for an almost as harrowing first person account, listen to the interview with Brett Archibald about surviving 28 hours after falling off a cruise ship: http://www.modernmann.co.uk/new/2017/10/24/61-lost-at-sea

Not quite a cruise ship, more like a 10 passenger boat. I wonder what would happen if one actually fell off a large cruise ship.

happens quite often and nearly everyone dies/goes missing

5mm wetsuit (or more likely drysuit given that he's a diver) saved his life far more than anything else. That's some serious insulation, though barely enough over such a long period of time. The article doesn't go into much detail in terms of the psychological aspects of the ordeal -- your life flashing before your eyes for days, can't imagine.

Divers' suits are not dry. There's water between the skin and the suit. Actually that warmed water layer is what isolates the body against the cold outside.

Earlier quoted context omitted.

I find it near impossible, mostly due to waves that push water into your eyes and mouth!

You can also float in seawater in the fetal position. Your head will be below water but it is easy to come up for air periodically.

Easy to periodically come up, like, every 30 seconds? 3240 times in a row?

No that's wetsuits. Dry suits don't let water in.

How much heat would you lose by submerging your head and neck, versus how much would you gain by keeping the fetal position? I'm not sure if that's a positive tradeoff.

"Hewitt was an experienced navy diving instructor with 20 years in the service, and he told his dive buddy that he would swim back to shore himself"

Very surprised that such an experienced diver would make such an incredibly dangerous decision. Or that his dive buddy would agree to it.

Possibly a decision based on over-confidence.

Exactly, wetsuits like, you know, the ones we're talking about:

Prolonged soaking in seawater, along with the friction from his wetsuit and fins, damaged Hewitt’s skin pretty badly.

This reminds me of a sign I saw at the top of a rather dangerous ski slope: « la neige ne reconnait pas les bons skieurs » ≈ “snow doesn't recognize good skiers” ≈ it's not because you're supposed to be good that you'll get special luck.
