There's a lot of that going around the internet. I think we'll have to wait a couple of days/weeks for the facts to come through. I don't think the media is reporting it accurately.

My gut check says that his boat got knocked down and either partially or entirely demasted. But, it's counterintuative to me that a 70 year old single hull keelboat would stay capsized and afloat for two months. I've sailed small keelboats that had enough flotation foam to do that, but unless he had retrofitted the boat with a couple hundred cubic feet of it, I wouldn't place money on it stayup afloat. I think the boat righted itself after the knockdown.

He had no emergency communications equipment (EPIRB or PLB), and his regular electronics didn't survive the knockdown.

If the boat remained upright and habitable (after bailing), it would go a long way to explaining his apparent good health. He would have shelter and stores of food and water in addition to what he caught and collected.
