I can think of at least four occasions in recent history
where center console boats were found floating upside down. The one the OP mentioned is the only one where the crew survived.
Shortly after that incident a boat went missing out of Hawaii
. The boat was found floating upside down the next day. The crew was not found. In fact the boat that was towing in the found boat capsized as well. Again the boat floated but as it was near shore the crew was picked up quickly. Only one suffered hypothermia. One actually swam to shore.
About a year ago two boys went fishing
here in Florida
. When they didn't return the searchers found the boat floating upside down. The boys were never found. The boat was then lost
and it floated for about a year before it was found on the other side of the Atlantic. One of the boys cell phones was still in it.
Going back a few years, a boat left the west coast
on a fishing
trip with four men
aboard. When it didn't return a search was started. The boat was found still afloat, upside down, with one man left clinging to it. The others had suffered hypothermia and drifted away in the night.
What I find interesting is how often outboard
boats turn turtle. It looked like the young boys who died had been working on the engine
when the boat flipped. The boat from the West coast
of Florida was anchored by the stern.
