Vessel 1 was riding in the wake of Vessel 2 with Vessel 1 to the stern and starboard of Vessel 2.  Vessel 2 then began to slow, at which time the Operator of Vessel 1 turned hard to starboard to avoid a collision.  After initially avoiding the collision, Vessel 1 then turned to port, circling to the left and approaching Vessel 2 from the port bow of Vessel 2.  The Operator of Vessel 1 misjudged the distance between the two vessels and let off the throttle intending to avoid a collision, however, Vessel 1 struck the starboard side mid-ship of Vessel 2 with the starboard stern bottom edge of Vessel 1.
