[Age of Reason]

"If he had any training in water craft safety he would have shut down the engine before abandoning ship, in fact, almost ALWAYS the best course of action is to stay with the vessel. Small vessels are designed not to sink.”

Even true for vessels that don't have built in flotation.

There's been many cases where a ship was abandoned at sea during a storm, only to be found still afloat after the storm had passed, surviving the storm on its own.

As for the fellow who jumped, unless there's something the story omitted (e.g. boat might have been capsizing while under weigh, as when turning too sharply for the speed, and he tried to jump clear), he probably just panicked.

That could be the reason he jumped and the boat was moving under him.
