RedactedNarrative: On 07/10/2017 I, Officer First Class with Maryland Natural Resources Police, received a complaint call from the dock master of Cambridge Municipal Yacht Basin (1 Mill ST Cambridge, MD 21613), regarding a vessel that damaged one of their vessel slips on 07/08/2017. I made contact with Subject approximately 1200hrs and he showed me where the accident had taken place. The vessel was still in the slip and the vessel description was the following: red in color sail boat, with a diesel 80 hp motor, and with the name “Magic Kingdom on the vessel. The vessel damaged the following: broke the right entrance piling for the slip (facing the Choptank River), damaged the second piling on right side (facing the Choptank River), and damaged the finger pier and damaged the left rear piling closest to the shore power box (facing the Choptank River). The " Magic Kingdom had the following damage: scrape marks in the midship area on both port and starboard sides, broken wooden siding on both port and starboard side, and paint chipped on both port and starboard side. The total damaged to the slipwere the following:  4 pilings scraped, 1 piling broken, and damaged to the 3ftx8ft finger pier. I documented and took pictures of the damaged property.
     
     I asked Subject did he observe the incident and he said no, but he did hear the initial impact. I asked Subject could he recall the conditions for that day and he said the following: daylight, clear visibility, and wind speed less than 10 mph. Subject stated that after he had heard the initial impact he ran outside his office to see what happened. He said that he observed the vessel Magic Kingdom was in the slip B-7 which is normally docked in Pier L slip 13. Subject stated that he made contact with the operator/owner of the vessel, who was alone at the time of this incident. Subject advised that Operator1 stated to him that he was having issues with his vessel’s transmission not going into gear properly and lost control due to the wind condition and mechanical issues.  Subject stated the Operator1 did give him his issuance information. Subject provided me with Operator1 information so I could make contact with him regarding this incident.
  
   I contacted Operator1 approximately around 1400 hrs and we agreed that we would meet tomorrow at Cambridge Municipal Yacht Basin to discuss the incident that occurred on 7/08/2017.
  
   On 07/11/2017 approximately 1200 hrs I met with Operator1 to discuss the incident that he was involved in.  Operator1 described that day being the following: clear, daylight, wind coming out of the WEST direction, and the water was calm. Operator1 stated to me that he was backing out of his slip L-13 at the Cambridge Municipal Yacht Club to move to another vessel slip at the same marina. 
  
  Operator1 then stated that once he had clearance from his boat slip he put his throttle in forward to head towards the other slip. When he did that his vessel jumped to a faster speed than intended and when he tried to slow the vessel down the vessel started to pick up more speed. Operator1 stated that he tried to slow the vessel down by placing the throttle in the reverse position. At this time Operator1 believed that his transmission cable was stuck or broken because his vessel would not react. 
  
  Operator1 stated that he shut off the engine, but  the wind pushed his bow to the east towards the lighthouse at the marina Operator1 advised he decided to steer to an empty slip instead of hitting the concrete breakwater. Operator1 said that his port side bow and anchor (which was attached underneath the bow) hit the entrance piling for the slip and broke the piling, then hit the midship piling, and bounced off hitting the finger pier stopping all forward movement. Operator1 said that Yacht maintenance looked at his vessel and declared that his transmission was malfunctioning at the time of the incident and was repaired this morning and they are going to fix other issues with the vessel. I told him to forward all his documentation of maintenance work to me when they were finish.
  
     Subject advised the damaged would exceed $2,000 and would have a marine contractor to evaluate the damage to give a more accurate estimate.
