RedactedNarrative: On June 29, 2018 at approximately 18:41EST, I, Officer, was dispatch to an injury related boating incident that occurred on Lake Cumberland in the Thomas Branch area of Russell County, KY. The operator of Vessel 1, KY registration (KY 0752 BK), had contacted KSP dispatch and requested for EMS to respond to Conley Bottom Marina and stated he was currently en route to that location. Once I arrived at Conley Bottom Marina I observed the owner of Vessel 1 operating the vessel in the idle speed zone and approaching where EMS and I were staged. The EMS crew quickly attended to the injured passenger, due to multiple lacerations to her leg. Her injuries were so severe that EMS immediately called for Air EVAC upon observation. EMS personnel stated Victim was going to be flown to the University of Kentucky Medical Center for further treatment due to the severity of her lacerations. I assisted EMS in transporting Victim from the boat into the ambulance. 
  When interviewed at the scene Victim stated she had been drinking throughout the day, and that she was on the back of the boat when she was thrown in the water and struck by the propeller. 
  Officer (KDFWR) then arrived on scene and assisted with the investigation.  It was very obvious that Operator had consumed some quantity of alcoholic beverages due to the strong odor that was coming from his person when speaking. Operator had very bloodshot eyes, slurred speech, and delayed reaction to all questions. Operator stated he had been drinking throughout the day. Operator also stated that Victim and he were in Thomas Branch trying to find a cove for the night. At one point during the hunt he was maneuvering Vessel 1 in reverse when he heard his wife go into the water and immediately scream as he had backed over her.
  After the preliminary interview I requested that Operator put on a PFD and step onto my patrol boat where I conducted standard field sobriety tests (SFSTs). Operator showed multiple clues of impairment in all SFSTs administered. Upon completion of the SFSTs I placed Operator under arrest for "Operating a Motorboat Under the Influence 1st" (BUI), and transported him to the Wayne County Detention Center. Officer remained with Vessel 1 and Marine Assist was contacted to tow the vessel to a secure facility.  
  Once at the detention center I read Operator the BUI implied consent warning in its entirety. Operator submitted to a breath test resulting in a BAC of 0.147. I then read Operator his Miranda Rights. Operator stated he understood his rights and gave me a written statement of where and how the incident happened.  I charged Operator with BUI in Wayne County. Due to the incident occurring in Russell County I contacted the Russell County Commonwealth Attorney in reference to pursuing an additional charge of assault in the second degree. 
  Photographs were taken on scene and when the vessel was retrieved from the water. Additional photographs were taken the following day due to low light conditions. 
  Victim was flown to University of Kentucky for further medical treatment the day of the incident and later released with stitches to her leg.
