RedactedNarrative: BOTH VESSELS WERE IN SLIPS AT THE MARINA AND BOTH WERE RENTALS. DOCK EMPLOYEES HAD JUST PUSHED V1 OUT OF THE SLIP AND THE OPERATOR GAVE IT TOO MUCH THROTTLE WHEN HE PUT V1 INTO FORWARD GEAR AND COLLIDED WITH V2. V2 WAS WAITING FOR V1 TO CLEAR THE DOCK BEFORE LEAVING THE SLIP. V1'S BOW HAD SLIGHT DAMAGE AND V2'S MOTOR COWLING AND ENGINE VALVE COVER WERE BOTH DAMAGED.
