I grabbed the tiller of a yacht that was about to cut a moored powerboat in half. The skipper (of the yacht) was in his first season racing. We crossed the finish line and gybed out the way of the other finishers. He chose a poor moment to relax and the mainsail took over. There was no way he was going to work out that he needed to stop fighting to make it turn back the way we were supposed to be going and that the only way out was to encourage the boat to turn the wrong way "more", so I did it instead. In the end it was really, really close. I'm not sure there was much thought involved. It was certainly very impolite of me to do it, but everyone concerned was very happy to not hear the crunch noise made when a yacht cuts another boat in half. We never really talked about it, but I've heard him reference it once or twice since so my vague fear that I made the whole thing up is unfounded. I really hope to not have to do it again, but I guess it's good knowing there's a part of me that does this kinda shit before I have time to think about it.
