RedactedNarrative: PER AZ CASE #17-003290:  
  On September 2, 2017 at approximately 1400 hours, V1, a water jet powered Bombardier craft bearing California registration was slowing to approach the shoreline of the Avi Resort and Casino after entering a marked no wake zone.  As the vessel slowed, the cargo of at least two coolers, an umbrella and other unknown gear shifted and hit the throttle lever as he tried to catch the shifting cargo.  This resulted in a sudden thrust ejecting the operator and two minor children passengers.  The unmanned V1 then struck multiple vessels beached on the shoreline with heavy Labor Day weekend crowds.  A pregnant female standing in the beached V2 fell when V1 struck the rear deck/transom of her vessel, crushing fiberglass and gelcoat for approximately 4"x28".  She was treated by EMS at the scene and transported to the hospital for observation.  The force of the allision caused V1 to rotate slightly to port, striking and damaging the steering yolk, upholstery and plastic cowling of V6, a PWC beached on the port side of V2.
  
  The unmanned V1 then deflected off the starboard stern of V2 at a slight starboard angle and collided with PWC V3 damaging the port, stern corner molding, tore the deck matting and tearing the raised portion of the rear seat, then continued parallel to the shoreline striking PWC V4 and PWC V5 .  V4 sustained paint transfer and slight scuffing, V5 only slight scuffing, but owner was standing next to her PWC when the allision occured and the impact caused her to drop her iphone into the water causing an approximately $900 property loss.  One of the bystanders then reached into V1 and shut it off by removing the lanyard (kill switch).  All five of the affected vessels were beached and unmanned at the time of the allision.
  
  The damage observed on V2 was estimated at approximately $3800.  The damage estimate of V3 was estimated at approximately $500.  V4 appeared to have negligible or minor scuffing damage along with V5.  The damage to V6 was estimated at approximately $400.  Vessel 1 did not appear to sustain any damage during the incident.
  
  During the investigation of the incident, the operator of V1 was suspected to be impaired.  Following an interview and performing field sobriety testing, operator was placed under arrest for failure to control his watercraft and operating a watercraft under the influence of an intoxicating liquor.  operator provided duplicate breath samples of .097 and .092 BrAC respectively.  He was released following preocessing.
