RedactedNarrative: The operator was identified and due to his unwillingness to follow Officer commands, the subject was handcuffed and placed in the back of Deputy patrol vehicle.  From the witness statements I had gathered the following: 
  
  - It took Operator (operator) multiple tries to dock his vessel, hitting the dock hard with the middle to stern of his starboard side while doing so.  
  - The damage to the starboard bow of his vessel was done prior to entering the marina.
  - He had no shoes and poor balance as he walked to the bar where he was refused alcohol.  
  - The manager had to stop Operator from getting back on his vessel to go home.  Operator originally refused to listen to the manager until the manager offered Operator food.
  
  Upon further inspection of Operator's vessel (FL9404PF), I observed that the front starboard bow was crushed in.  There were green and brown transfer marks on the fiberglass and rub rail at the initial point of impact.  I looked for damage done to the dock from Operator docking, but could not find any transfer marks or evident damage.  Because the dock was made of cement, the lack of damage and transfer marks on the dock itself, and the green and brown transfer marks, it was apparent that Operator did not strike that dock.  The green and brown transfer marks on the vessel suggested that Operator's vessel might have struck a green channel marker.
  
  After observation of the vessel, Operator was removed from the back of Deputy patrol vehicle for further questioning about the damage to his vessel.  When I asked Operator about the damage to the front of his boat, he stated "I know my boat, and it was always like that."  I tried to explain to him that there was significant, fresh damage to the front of his boat.  I asked if he remembered hitting anything on the way over to the restaurant and he immediately became defensive and unwilling to answer any of my questions.  
  
  During my initial questioning with Operator, I noticed a strong odor of an alcoholic beverage coming from his facial area, slurred speech, bloodshot, watery eyes, and poor balance standing in one spot.   I asked Operator to perform standardized field sobriety tasks, which he refused.  I also asked Operator for a lawful breath sample to determine his blood alcohol level which he also refused.  I then read Operator implied consent from prepared text and once again asked for a breath sample, which he refused.  I then stated he was under arrest for boating under the influence (BUI) and he was placed back inside Deputy patrol vehicle while Officer truck was prepared for transport.  Once it was ready, Operator was moved to Officer patrol truck and transported to the Marathon Jail.  Operator was charged with BUI and refusal to submit to a breath test.  Operator asked if the vessel could be left at the restaurant. The restaurant manager refused responsibility of Operator's vessel, so a commercial tow company was called.  Florida Keys Towing took responsibility of the vessel, and trailered it to their compound.
