RedactedNarrative: On the listed date and time I, US Park Ranger, was dispatched to a report of a vessel inbound to Katherine Marina on which there was a patient with a head injury.  US Park Ranger brought the NPS ambulance (R1) to the launch ramp while US Park Rangers and I responded by patrol vehicle.  Dispatch advised that they had no further information regarding patient condition, and as such I dispatched Bullhead City EMS to assist with patient care.
  
  A vessel arrived at the Katherine courtesy dock with a male holing a towel to his head.  I saw that the towel had minimal blood on it, and I saw that VICTIM was alert.  VICTIM was oriented to person, place, time, and prior events.  VICTIM told me that he was operating the vehicle when “something hit me.”  Passengers told me that the fabric bimini top on the boat had broken free while the vessel was under power, and the metal pole supporting the top had struck VICTIM in the head.  VICTIM identified a point at upper right portion of his head where he was struck, and denied being struck at the base of the head, neck, or back.  VICTIM stated that he was able to walk, and we walked to R1 which was waiting at the end of the courtesy dock.  As soon as VICTIM got into R1, Bullhead City EMS arrived on scene and advised that they would take patient care.  I was advised by the Bullhead City Paramedic that VICTIM had a 2” laceration on this scalp that would likely require sutures, and that VICTIM had declined treatment or transport to the hospital.
