For those being suspicious - there is footage from a beach side cafe from when the storm hit the cost. Carnage. From flags fluttering moderately to them being (and everything else) being chucked about despite the ballast in the bases - in the blink of an eye. It looks like it was blowing well over 100mph. You wouldn't dare go out on the street in that never mind get in a huge sailboat on the open sea.
If they had any sail up and the captain was off guard for about 5 seconds, it's all too easy to believe it turned catastrophic in the blink of an eye. Its a huge vessel - 150ft, 3 times your normal cruiser, and whilst there's ballast and much design work gone into it to guarantee stability, the draft seems shallow and it has open deck areas covered with canopies at the rear, and solid roof at the front - perhaps the wind whipped under these once the boat starts to broach.
