Drinking and driving don’t go together. Common knowledge. But neither does boozing and boating.

Which it appears is what the party in the following video got into, before they engaged in an all-out brawl on their rental vessel on the Choptank River, near Baltimore, Maryland.

A couple was cruising on another boat (along with their smartphones, obviously) and captured the footage below, which is eye-opening and … beefy, to say the least. The documenters were part of some sailing competition at a nearby yacht club, and weren’t at all cool with the fist throwing, whatsoever. They called the United States Coast Guard and local police, who eventually sorted out the messy scene, and the estimated $3,000 worth of damage.

 

Maryland National Resources Police tweeted this out, shortly after the incident:

No word from the USCG.
