I don't get this. I have watched this over and over... this is an expedition yacht. Even if she was light for launch, this shouldn't have happened. A boat should rite itself. The only thing I can think of is look on the back port side - something is pumping water furiously as soon as it goes in the water. The door to the engine room is OPEN just before the launch. I think it took on water in the engine room as it went back in the water at an angle and immediately swamped. They claim it was the trolly falling off the ramp. That still shouldn't have done that if the boat could rite itself.
