RedactedNarrative: On 6-15-2018 I, Cpl. received a call out from DNR Communications in reference to a vessel accident in the area of Ego Alley in Spa Creek, Annapolis MD.  I arrived on scene and met with subject1, who advised his vessel was struck by another vessel.  Subject1 stated while he was at dinner with his wife he received a call from the Annapolis Harbor Masters office advising his vessel was struck by another vessel.  Subject1 advised his vessel was tied up in slip when another vessel backed into his vessel causing minimum damage to the starboard side mid ship area of his vessel.  I, along with Subject1 looked over the damage to his vessel and it was only minor scratches at this time.  Subject1 started to rub the window and some of the scratches rubbed out by hand.  The damage was to a window, gel coating just above the water line and a window blind inside the vessel.  This vessel is scheduled to be lifted out of the water to check for any damage below the water line.  Subject1 advised he would like to file a boat accident report for insurance reasons.  Subject1 provided witness information to the accident.  I made contact with the witness, who was taking pictures when the vessel accident occurred.  Witness provided this officer with pictures of the striking vessel.  She advised the striking vessel came in Ego Alley and was turning around when it backed into the Subject1 vessel.   
  
   At this time I was met by the Harbor Masters Office employee.  He advised the striking vessel tied up for a short time waiting for me to respond to the area.  After approximately 20 minutes Subject2 advised the striking vessel to leave the dock that his vessel was secured to and stay in the area.  Subject2 provided me with the striking vessels  name "SEVERN ENDEAVOR" and registration number of MD 6319 BW.  I conducted a search through MD. Compass and located the owners of the striking vessel.  
  
   On 6-16-18 I arrived \ to speak with the owner of the striking vessel.  I was met by a Subject3 who advised his son was involved in a minor boat accident on 6-15-18 in the area of Spa Creek.  Subject3 made contact with his son and advised him to come to his house so I could interview him.  Operator2 arrived within 10 minutes and stated " I was trying to turn around in Ego Alley using my vessels side thrusters when they went out, at that him I slowly placed my vessel in reverse and the vessels motor cut off".  At that time Operator2 advised he had 2 friends try to stop his vessel from hitting Subject1s vessel.  Operator2 advised he struck Subject1s vessel with the stern swim platform on his vessel causing some damage to both vessels.  Operator2 advised he made contact with his boating insurance company and advised them of the boat accident.    
  
   At this time I provided Subject1 with Subject3's vessel insurance information.
  
   No charges are to be filled in this boat accident due to mechanical failure on Subject3's vessel.
