RedactedNarrative: On 03/21/2020 at approximately 1845 hours, I was notified by Grovetown dispatch to respond to the area of Lake Oconee at Interstate 20 in reference to a boating incident. The initial complaint was called in by Greene County so in order to get additional information, I called Greene County dispatch. I was informed a boating incident occurred and one of the occupants of the jet ski had been hit by another vessel and suffered a broken leg. 
  
  	Upon my arrival, I determined the incident location to be in Greene County, Georgia (Lake Oconee) waters of the State. As I began to assess the scene, both injured parties had been removed from the water and were being treated by Greene County EMS. During my investigation, it was revealed that the injured parties were identified. Operator2 was transported by Greene County EMS to St. Mary's located in Greensboro, Georgia and V2 occupant1 was transported to Piedmont Hospital Athens located in Athens, Georgia.  both subjects stated the incident happened so fast they were not sure what happened. 
  
  	As I continued to speak to Operator1, he confirmed he was operating the above vessel and stated they were attempting to spray one another with the jet of the ski. As Operator1 continued to talk, his speech appeared to be thick tongued and slurred. I also observed his face to be flushed/red along with glassy eyes. Due to my observations of Operator1 and needing to gather more information for the investigation, I requested Operator1 to place some shoes on and step off his jet ski onto the shore. Once on the shore, my suspicions were confirmed.  I detected a strong odor of an alcoholic beverage coming from Operator1's breath and person. Operator1 was also unsteady on his feet as he walked. At this time, I requested (and he agreed) Operator1 to lean against the guard rail in a secure position. 
  
  	At this time, I asked Operator1 if he would perform a series of tests to assist me in determining if was safe for him to operate his vessel. Operator1 agreed, and I performed the HGN test.  I informed Operator1 that I was going to check his eyes.  Operator1's pupils were consistent in size, no sign of resting nystagmus and appeared to track equally.  As I started this test, Operator1's eyes did not pursue smoothly.  I observed distinct and sustained nystagmus at max deviation.  I observed onset of nystagmus prior to 45 degrees.  Operator1 exhibited a total of six clues. Operator1 was positive for vertical nystagmus.  Operator1 performed poorly on finger to nose test, palm pat and the hand coordination test.  See SFST form and video from screening for details.  
  
  	At 1949 hours, same date, Operator1 tested positive on the portable alco-sensor.  At this point in time, due to my training and experience in detecting impaired operators for more than 25 years and the totality of circumstances, I advised Operator1 that he was under arrest and read his Implied Consent Warning for Suspects Under Age 21 at 1951 hours.  Operator1 agreed to perform a state administered chemical test of this breath.
  
   	Operator1 completed a breath test on the Intoxilizer 9000 at approximately 2021 hours and his blood alcohol concentration was 0.186.  While at the boathouse, Operator1 was issued citations for the following:  boating under the influence, reckless operation, and failure to me
