Wow!! This guy was at our marina a few days ago and I had a long chat with him. Glad he is OK.
He was indeed in a Corsair and was a very experienced sailor. He sailed from Mass to BVI last fall offshore and mad it in SIX days...racing sails and totally rigged to single hand. He told me that the boat was not built to weather storms at sea so he relied heavily on a good wind forcast that let him out run anything nasty. He seemed like a very confident but quiet guy who had his own well thought out way for going to sea. That survival suit says he knew the risks and was prepared.
The coast guard is calling for at least two other sail boats here for the last few hours in a full blown gale and tornado warnings up. Crazy weather to be out in.
