No injuries, fortunately. But some real chaos getting the boat back to shore; that's likely when much of the damage occurred.
I was on shore at the time, an experienced multihull sailor was out on it. I happened to be watching through binoculars. He was foil-borne and crashed down, which seems to be fairly common. Didn't seem like a big deal. But then it slowly rolled to the right, then stern down. Once the cockpits filled, it rotated bows up. We tried to pull the bows down by another boat, to no avail. At some point, I noticed that the starboard ama was buckled and the inspection port was open. The ama eventually sank completely. We had to float it up with inner tubes to get it to shore. No idea if the ama buckled during the crash, or while we were pulling on it later. Can't figure out how that happened?
Will post photos when I figure out how!
