Yup. It flipped. I have heard several stories, but only one that sounded plausible from a guy that runs the gas dock nearest the accident site. We drove out and saw the boat before it was recovered. The bottom was still intact, but that was all I could see. A friend of mine was parked in the channel between Maurepas and Ponchartrain when he went by just before the accident (less than a mile). Said he was moving pretty fast, but they didn't see anything unusual. I don't know anything about injuries.
