RedactedNarrative: On August 6, 2016 at approximately 4:00PM, myself (Cpl.) and Officers were dispatched to the Isle of Wight Bay, Worcester County Maryland for a report of a boat grounding with 1 subject injured. Upon arrival I noted 7 people in the water with a pontoon boat displaying a Maryland registration of 2857 LB attempting to maneuver in between the people in the water. I noted several different people grab at the controls of the vessel none of which appeared to be in any condition to operate the vessel.
  
  I ordered the subjects onboard the vessel to shut off the engine to which they complied. I noted a subject in the water who appeared to be injured. I could see blood on his body and another subject who was later identified as Operator holding a towel on Victim's arm and hand area which was also covered in blood.  
  
  Officers attempted to assist Victim onboard our patrol boat. As they did Operator let go of the towel on Victim's hand. At that time blood started to spray out in large volumes from the wound. At that time Officer applied a tourniquet to Victim which controlled the bleeding. We got Victim and Operator onboard our vessel. A good Samaritan helped us gather all the other subjects in the water and get them back onboard the pontoon boat. I noted that the pontoon boat was covered with numerous empty alcoholic beverage containers as well as blood. I also observed that all the subjects onboard the pontoon boat appeared to be intoxicated and not in a condition to operate the vessel. 
  
  At that time Ofc. took over the helm of the pontoon vessel. As he did we observed a female who we had not initially seen emerge from underneath the pontoons at the engine block. Ofc. had to immediately shut the engine off and assist this person onboard the vessel. Had the vessel been put in gear this person would have likely suffered very serious injuries. Once all subjects were accounted for myself and Ofc. transported Victim and Operator into shore at Bahia Marina.
  
  Ocean City EMS was on scene awaiting our arrival and immediately took over patient care as we docked. While speaking with both Victim and Operator I noted a strong odor of an alcoholic beverage on both of their breath and persons. I spoke with both subjects to inquire what had happened. Both subjects advised that they had rented the pontoon boat and had anchored on spot near 20th Street to swim. While anchored Victim jumped into the water striking his hand on some piece of metal from the vessel. Operator realizing Victim had been seriously injured jumped in the water to assist him. Neither subject could recall how the vessel came unanchored. I had noted on arrival that there appeared to be no sign that the vessel had been previously anchored. There was no line with an anchor overboard and the vessel was drifting and under power during our encounter with it. I also noted that the original report to emergency serviced was that the vessel had run aground. I also thought it unusual to find the amount of blood present inside the vessel with the patient having apparently received the injury outside of the passenger area and then located in the water on our arrival. Ocean City EMS transported Victim to Atlantic General Hospital for further treatment.
  
   Ofc. met with and interviewed the other passengers. He also advised that all the subjects he spoke with appeared to have been consuming alcoholic beverages. They advised that Operator had been the responsible party for the vessel and the one authorized to operate the vessel per the rental agreement with the company. They also advised the Operator had been operating the vessel just prior to the incident. They did state the vessel was anchored at the time of the incident. 
  
   I spoke with Operator again. He stated that he had been the primary operator of the vessel. He stated that they stopped and had anchored the vessel. At that time he consumed 3 beers.  He said they planned to stay anchored for a while before the injury took place. While talking with Operator I noted that his speech was slurred and that his eyes had a watery and glassy appearance. I asked Operator how they had planned on getting back since they all had been consuming alcohol. Operator advised that they were going to stay anchored long enough that the effects of the alcohol would have worn off. 
  
   I asked Operator how far he had gone in school and if he was familiar with the English Alphabet. Operator advised that he had completed high school and was familiar with the English Alphabet. I asked Operator to recite the English Alphabet starting at the letter "C" as in Charlie and ending at the letter "X" as in X-ray without singing. Operator recited C-Z pausing at times and then singing at times the alphabet failing to stop at X. 
  
  I offered Operator a preliminary breath test to which he consented to take. The results of the test showed an blood alcohol concentration of .13. At that time I placed Operator under arrest for operating a vessel under the influence of alcohol. I read Operator a NRP 482 advise of rights form. Operator verbally stated and signed the form refusing any further testing. I issued Operator citations for operating a vessel under the influence of alcohol as well as a copy of his NRP 482. Operator, the rented vessel and all its passengers were picked up by agents of the rental company. All of the above events occurred in Worcester County, Maryland.
