Vessel 2 was operating in the Upper Straight Channel and had just passed the red #10 buoy on a south/southwest course; Vessel 1 was entering the Upper Straight Channel and had just passed buoy #10 on a south/southeast course.  At the time just prior to the incident, Vessel 1 was approaching Vessel 2 from the rear and starboard of Vessel 2.  The Operator of Vessel 1 observed the course of Vessel 2 and tried to avoid collision by cutting his throttle.  This maction was unsuccessful and the bow of Vessel 1 struck the rear starboard side of Vessel 2 causing damage to both vessels.  Both vessels were able to leave the scene on their own after the collision.
