Factual error: At 300 meters, we see the hull starting to cave in - from the outside. But the outside hull is only a cover. The preasure hull is below that. There is water behind the outer hull, so it would never cave in that way. We actually see the double hull in a shot where we pass from the inside of the boat through the double hulls and out into the sea.
