Reminds me of this older story, of Harrison Okene, who was trapped in a capsized boat at the bottom of the ocean for 3 days: https://www.theguardian.com/lifeandstyle/2023/sep/26/i-survi...
video of his rescue: https://www.youtube.com/watch?v=um1ym9u8XaA
Randomly, the next year, he rescued his friend when their car goes off a bridge into water. He later became a diver!
Or a mini Poseidon Adventure
If I remember it right, Mythbusters did the "sinking boat will pull you under" and found it was a myth?
they busted it with a 9 ton boat but now I’m unconvinced because they did demonstrate the effect with a large weight dropping straight down in a pool, so what effect was that?! They were testing Titanic myths and didn’t touch on the fact that Titanic famously dropped like a stone!
How could 3 adults, even lying perfectly still, not use up all the oxygen in that air pocket within 35 hours?
I thought human beings needed several cubic meters of fresh oxygen (at 1 atm) per hour…
You got me wondering and I thought maybe there was some kind of gas diffusion where carbon dioxide is absorbed by the ocean water instead of building up in the enclosed space, and finding the most closely related stack exchange question I think I’m satisfied with this answer:
probably that four-foot bubble communicated with a larger volume or air under the hull of the boat - and that's the most reasonable explanation of this miraculous survival.
When picturing it we might assume the rest of the boat is flooded and this pocket of air is all that remained but that may not be the case.

Mr Nimbus gave them gills to save them and wiped their memory :)
Not at 1atm. The air was pressurized.
It doesn’t sound to me like the boat actually sank. In the article it mentioned that they heard the rescue helicopter from within. Wouldn’t that imply that the pressure inside would be one atmosphere? Am I thinking about the physics of this wrong?
Sound does carry remarkably well through water - but you're right. The ship capsized, but the hull held enough air that it stayed afloat.
It was floating upside down.
There is a picture towards the end of the story.
How is that? It was at surface pressure and then rolled over.
