We'll just agree to disagree. Looks to me like the boat could have been going 10 knots but I am not an expert. Is that "high speed"? I also can't agree that someone holding a Captain's license is fully responsible for a boat that they may be on as a guest. I do agree that in this case the Captain, that was acting as Captain, is responsible and I would think that this will be very hard for him for the rest of his life. Especially so since it appears these were his friends.

Should he lose his Captain's license? Maybe. Should he go to jail? I don't think so
