RedactedNarrative: Vessel one was towing a tube occupied by her two children and performing repetitive circular maneuvers.  Operator of vessel two stated that he observed the maneuvers coming closer to his powerless personal watercraft (PWC).  As the tube approached his PWC, he started the ignition and attempted to apply throttle so the tube would miss him.  Inevitably, the tube being towed by vessel one struck the stern of his PWC throwing him and both of his children into the water.  
  
  The boy was temporarily rendered unconscious and the girl sustained a cut to her head.  Officer with Henderson Police Department arrived on scene and advised that the father refused ambulatory transport for his children but was driving them himself to Lafayette General Hospital.  
  
  I was later informed that the 10 year old girl was treated for a cut to her head and released.  The 12 year old boy was admitted to hospital for overnight observation.  
  
  All subjects were wearing PFD's at the time of the incident and alcohol/drugs are not believed to be a contributing factor.
