Vessel 2 (with three persons on board) turned in a circle several times to create a wake for Vessel 1 (with two persons on board) to jump.  As Vessel 2 was coming out of one of these circle maneuvers, Vessel 1 was coming straight toward the port side of Vessel 2.  Vessel 2 turned hard to starboard and Vessel 1 turned hard to port, but the two vessels still collided.  Both Occuoants aboard Vessel 1 were injured as a result of the collision.  Vessel 1 suffered extensive damage to the starboard side and Vessel 2 suffereed damage to the port side.

Operator Inexperience was listed as a secondary cause based on the fact that the Operator, although having significant experience with boat operation in general, had limited experience (and no boating education) regarding the operation of Vessel 1.
