RedactedNarrative: On August 3rd, 2016 I, Cpl., received a report from DNR communications of a vessel at Mear's Point Marina that had struck another vessel.  I responded to the scene to investigate.   I spoke with Operator1 onboard the vessel Out of Control.
  
  Operator1 is employed by Alliance Marine which manages the maintenance of Out of Control.   At around 1100 hrs Operator1 was at the flying bridge helm of Out of Control returning from the travel lift and putting it back into the vessel's slip on "D" dock.  He entered the slip bow first because he wanted a previously damaged section of the rub rail along the finger pier.  The vessel was mostly into the slip when Operator1 wanted to slow down so he put both engines into reverse.  He was then unable to get the engines out of reverse.  The gear indicator lights flashed and beeped repeatedly.  Operator1 went down to the back up controls in the cockpit but they did not have any affect.  Out of Control continued in reverse out of the slip across to "C" dock.  The vessel Legacy was secured in it's slip on C dock with nobody onboard.  Out of Control struck Legacy in the bow.  Legacy rode up Out of Control's swim platform and then pushed through the transom door breaking it off in the process.  Legacy was pushed backed into the dock damaging its swim platform.  During the collision the piling off the Legacy's port bow broke off a couple feet below the waterline.  It seems likely the piling broke from the force of the Legacy pulling back on the dock line attached to it 
   
  After the collision Operator1 was able to shut the engines down.  Out of Control drifted through the marina and until a captain and crew from another boat was able to help pull it alongside the fuel dock.  Later in the afternoon, the owner of Out of Control was able to manuveur the vessel back into it's slip with no issues
   
  The main helm engine controls were manufactured by Glenndinning Marine Products.  They have an electronic linkage to the engines.  Operator1 inspected the cockpit engine controls.  He stated they should have been mechanically connected to the engines when originally installed but when he inspected them they were not.  They may have been upgraded to electronic linkage.
   
  Subject1 was onboard Out of Control assisting Operator1 during the incident.  He was originally on the port side of the vessel getting ready to secure a line.  When the vessel stayed in reverse he went to the cockpit  at which point Operator1 came down and was attempting to use the cockpit controls.  When it was obvious a collision was imminent subject1 took shelter in the cabin.
   
  Operator1's and subject1’s statement are consistent with the damage on all of the vessels and the piers. I have not been able to locate any witnesses to the actual collision.  Subject2 was on a nearby vessel and responded when she heard the collision and then assisted getting Out of Control along the fuel pier.  Her statement is attached.
   
  All events occurred in Queen Anne's County, MD.  No further law enforcement action is required at this time.  The incident is closed
