RedactedNarrative: On Saturday August 13, 2016 I responded to a report of a vessel hit and run involving a sailboat. At approximately 1800 hours I arrived at the northwest corner of Egmont key and made contact with the occupants of the struck vessel, FL 7458FT. The owner/operator stated that a sailboat struck their vessel at the stern, disabling their motor, and scraped the starboard side and continued to drive off. He stated the operator of the sailboat was a tall white male not wearing a shirt. V2 owner pointed at a sailboat approximately 2 miles away and stated it was the one that hit his boat. V2 owner’ vessel was currently disabled due to the accident damage. I instructed V2 owner to wait for a tow, while I went to meet up with the sailboat.
  
  	Approximately 5 minutes later I arrived at the location of the sailboat FL9786NV, which was drifting with its engine on. As I approached the stern of the vessel I observed a tall white male inside the cabin. I announced myself and requested the occupant to step outside. The occupant stepped out onto the deck and was having difficulty standing.
  
  	I tied up to Operator1’s vessel and asked him if he was involved in an accident at Egmont Key to which he replied “No”. I informed Operator1 that a vessel was struck at the island and identified his vessel as the striking one. Due to rough weather/seas I asked Operator1 if he could step onto my vessel for further questioning. He consented, and stepped onto my vessel. Upon contact with Operator1 I detected a strong scent of an unknown alcoholic substance emanating from his breath. Operator1 also had red and watery eyes. I also observed multiple empty beer cans on the deck of his sailboat.
  
  I untied my vessel with the sailboat to avoid damage from the rough seas. I asked Operator1 to sit on the bow seat of my vessel. He sat down on the bow gunwale and was visibly swaying. I had to repeatedly ask Operator1 to stay seated on the center seat of my vessel. He continued to stand up and walk around my patrol vessel.
  
  	I asked Operator1 where he was sailing from. He could not recall where he had been earlier but stated he was at Egmont Key. He slurred his speech and paused repeatedly during conversation. 
  
  Coast Guard arrived to assist. I asked Operator1 how much he had to drink to which he replied "about thirty percent" I asked what that meant and again he replied "just thirty percent". Due to the multiple indicators of intoxication I began to conduct a sobriety investigation. Prior to conducting the seated tasks I ensured that Operator1 was seated so that he was comfortable and stable. Each task was explained and demonstrated to Operator1 and I confirmed that he understood each one prior to beginning the tasks.
  
  Sobriety Tasks
  
  The first task given was the Horizontal Gaze Nystagmus (HGN). I confirmed that his pupils were of equal size and were tracking equally. I observed no resting nystagmus. During the task I observed a total of 6 clues. (lack of smooth pursuit in left and right eye, distinct and sustained nystagmus in left and right eye, and onset prior to 45 degrees in both eyes) Operator1 had to be reminded multiple times to keep his head still.
  
  The next task performed was the palm pat. The instructions had to be read to Operator1 multiple times before he said he understood. A total of 7 clues were observed 
  
  The next task was the finger to nose. I observed a total of 11 clues. In the instruction and performance stage Operator1 started before I told him to, did not tilt his head, kept his eyes open, and swayed his head. The instructions had to be repeated to him multiple times before he stated he understood. After the 5th attempt, Operator1 stated he didn’t want to continue with the task.
  
  ARREST:
  
  	Based on my investigation and observations, I concluded that Operator1 was impaired and placed him under arrest for boating under the influence at 1832 hrs. F.
