Wouldn't have had a problem if the kid had a gun and shot him as soon as he boarded the other boat. Guy has a ton of DUI and assault convictions. It also started for the stupidest reason, and was a case of mistaken identity.
The boat rager was speeding all around, and got yelled at for it by some boaters. They're out on boat again drunk, and one of the other assholes goes "Hey that looks like the guy from yesterday", and they all started teasing him that he should go over and punk the the kid.
Sad thing is, he was apparently a good fishing charter service. Had a 4.5 star rating on google.
