According to a comment posted on YouTube with the video, "Every start this kid would appear at the boat and hold position by tacking for the entire five minute sequence. The perpetual motion award goes to this kid who, during this sequence alone, tacked 48 times!"
He certainly seems to scare anyone else way from taking his spot.
I wonder if this would work for me in Lasers? Must try it at the New England Masters in a few weeks.
