RedactedNarrative: Vessel 1 was heading northwest at approximately 20 miles per hour, operating in the ski zone pulling one of the Occupants on a tube.  Vessel 2 was also heading northwest at approximately 25 miles per hour in a path parallel and to the port side of Vessel 1.  Vessel 2 turned slightly to starboard to try to throw a wake onto Vessel 1.  Realizing the imminent collision the Operator of Vessel 1 turned slightly to starboard; the Operator of Vessel 1 turned hard to port at the same time.  The speed and prioximity of the two vessels made the actions taken insufficient to avoid the collision and the starboard bow of Vessel 2 impacted the port side of Vessel 1.  Vessel 1 and Vessel 2 both shiftted into neutral following the collision at which time the Occupant being towed behind Vessel 1 swung to the port side of Vessel 1 and impacted the port side of Vessel 2.
