In 1995, a 20-year-old U.S. Marine fell overboard from an aircraft carrier in the Arabian Sea. He did what he'd been trained to do: he "kept his cool, inflated his uniform into a life preserver, and floated for two days and two nights until he was picked up by a Pakistani fishing boat." [0]

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.

What? You said: > Divers' suits are not dry Wetsuits are wet. Drysuits are dry. Sometimes divers wear wetsuits, and some of the more experienced ones wear drysuits.

It's getting ridiculously difficult to write something in HN without receiving some absurd answers like that.

The comment I responded to said that divers use drysuits so this guy should be wearing one. No matter how you put it, the article says that the guy used a wetsuit.

Please, stop for a moment and let this little fact sink: the guy wore a wetsuit and the article clearly states this much.

Yes, I could have said that NOT ALL Divers' suits are dry. But the fact is that MOST of them aren't and in the single specific case THAT WE ARE TALKING ABOUT, the suit wasn't dry.

So why the hell do I need to clarify these obvious things? I have no idea.

Oh, and the fact that people use downvoting to "win" these petty fights.

How does one inflate an uniform?

So, a guy with tons of experience goes for open water dive without a diving marker or diving alert device, decide to leave his dive-buddy and return to the beach by himself. Some other articles says he was a navy veteran. That would probably explain his overconfidence, as those are things that recreational and tec divers are explicitly trained not to do.

Lots of diving accidents reports starts with someone being overconfident (ignoring the recommended safety limits or his personal limits), ignoring safety-checks and/or losing his diving buddy. I guess this is one of those. I like reading those kinds of reports because it shows how things can go wrong, even for experienced divers. And how to be prepared for those problems. It also shows that most diving accidents happens usually because of human error instead of equipment failure.

The good thing: He's still alive. He returned to the diving spot a few years later (to take a picture for his "treading water" book) and he became a "Water Safety Ambassador" in NZ. And his history might serve as an example during diving safety classes.

The Ph. are just off the equator. I’ve been in the water in northern Australia and the water was 30c and on the verge of being too warm. Definitely not refreshing, felt like a salty bath tub.

Due to water being a way better conductor of heat than air you lose heat up to 75% faster than in air. Even 30°C warm water can therefore quickly lead to hypothermia if unprotected. Ever seen scuba instructors in warm countries? While their customers would often submerge in nothing but a swimsuit the instructors would often wear 6mm full body wetsuits due to longer exposure. And yet a lot of them are shivering in the…

I've been shivering in the water at 27 degrees Celcius in Australia (diving, no wetsuit, sitting on the bottom). Admittedly I have a very slender build, but clearly 27 degrees is below my equilibrium temperature when not in activity.

Some people simply cannot float. Me included. I've had 3 different instructors try to tell and show me that everyone can float. I can't. I have 5 swimming certificates, I'm fit, but I think I just don't have enough body fat? Even in the Red Sea (if it's called that in English) I can't float. Not for more than 5 seconds.

Maybe your bones are too dense, though to be honest, I've never heard of anyone with your issue in floating/treading water. I've always assumed that everyone has enough buoyancy to float most of their body.

I'm super skinny and sink straight to the bottom of a pool. Same issues :(

Non-stop in the sense that there aren't any staged pauses, but she undoubtedly stopped to sleep at some point. What really blew my mind is that she finished 10 hours ahead of the next competitor.

She only slept 1 minute actually.

So not nonstop then.
