RedactedNarrative: The operator (O-1) on a rented personal watercraft (V-1) and had no occupants nor riders.  The surf conditions was rough that day and as O-1 made a turn on V-1, she hit a wave which caused her chin to strike V-1's steering.  
   
  When I arrived on scene and looked at O-1's laceration, I summoned EMS who arrived and placed a butterfly bandage on her chin.  O-1 was then advised by EMS to seek medical attention as the injury would require stitches.  While EMS was tending to O-1, I talked with O-1's mother and told her of the injuries and the treatment EMS suggested.  Victim  had a deep cut under her chin and EMS was called.  EMS placed a butterfly bandage on the cut and she was advised to seek medical attention for stitches.
