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!
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.
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?

Randomly, the next year, he rescued his friend when their car goes off a bridge into water. He later became a diver!

I thought human beings needed several cubic meters of fresh oxygen (at 1 atm) per hour…

There is a picture towards the end of the story.
Put a barometer in an empty, upside-down cup. Force the upside down cup 1/2 way down into the water, trapping the air inside.
The barometer will be at the sea pressure of the bottom of the cup.
