A few years ago, there was a video of a catfight between college girls during spring break. The spring breakers were on a couple of boats, and two of the girls got into it. I don't remember it being anything extraordinary, but it was a real fight.
There was also a video on YT a couple of years ago, showing two women fighting on, of all places, a white water raft, while going down some rapids! It sounds crazy, but it really happened.
Also, there was a TV show that ran from 1958 to 1961, called Sea Hunt. It starred Lloyd Bridges. I distinctly remember an episode where two women had a brief catfight on his boat.
That's about all I can think of off the top of my head.
