RedactedNarrative: Operator of Boat A was headed southwest toward the channel and observed a PWC moving at a high rate of speed heading north, then moving in tight circles, then accelerated south, then turned in a broad circle toward boat A.  Operator of boat A slowed the boat, began waiving his hands and yelling to get the driver of boat B’s attention noticing that he was looking behind him instead of the path he was traveling.  Operator of boat B let off the throttle once he heard me, then hit the side of the boat with the front right of his PWC.  He then accelerated causing the back of the PWC to hit the rear of boat A.  Operator of boat B then sped off toward the north about 150 yards, then stopped.  Operator of boat A observed that he was adding a passenger who was floating in the water.  Operator of boat B and his passenger then returned to the side of boat A, with the driver telling me had had to pick up his passenger who had fallen off, which was the reason he was looking behind him instead of the path he was traveling.
