RedactedNarrative: Unit 1, Unit 2 and Unit 3 were docked at the fuel dock on Morgan Creek. Unit 2 was between Unit 1 and Unit 3. Unit 1 was in front of Unit 2. Unit 1 untied from the dock and throttled up, forcing Unit 1 forward  and collided with the side of Unit 2. Unit 1continued forward, colliding with the bow of Unit 3. Unit 1 then continued into Moran Creek before coming to a stop. Minor child received a two inch laceration to the back of the head and received approximately 20 stitches for the injury. 
  
  I was advised by witnesses that the rental boat was un-docking when the operator forced the throttle forward, forcing the boat to collide with the back starboard side of the Carolina Skiff. The rental boat went over the top of the boat and back into the water, then colliding with the Boston Whaler's bow. The rental boat continued underneath the Boston Whaler, at which time I was advised that the passengers of the rental boat lifted the Boston Whaler off of the rental boat. The rental,  boat, still in gear, then continued further into Morgan Creek. The operator finally grabbed the throttle and placed the boat into the neutral position. Witnesses from the dock, boarded the Boston Whaler and assisted the rental boat in bringing it back to the fuel dock where it was tied up when I arrived on scene. 
  
  It should be noted that the operator of the rental boat advised me that a dock hand with Low Country Boat Rentals advised her that she had to use a lot of force to get the boat to go into gear. She also advised them that the gauges were not working on the rental boat. She advised that she was told, "don't worry, the gas tank is full." She advised that she had been operating boats all of her life. There were ten passengers on board the rental boat. The other boats had no passengers on-board. 
  
  Photos were taken, the owners of the boats were notified, BAR was completed, and witness statements were taken. Operator was issued a warning for negligent operation. Victim was discharged from the hospital after receiving stitches for his laceration.
