RedactedNarrative: Vessel 1 was struck by Vessel 2 while moored to the dock.  No injuries were sustained.
  
  I asked Operator2 to explain to me what happened.  OPERATOR2 stated that when he was initially operating the vessel, the throttle had gotten stuck in the forward position and it stuck when he was trying to maneuver the vessel away.  As I inspected OPERATOR2's vessel, I had him start the motor to check the throttle control.  The throttle was stiff and difficult to adjust.  
  
  Vessel 1 was secured to the dock Bow in (front) and on the Starboard (right) side.  Vessel 2 was underway heading eastwardly when OPERATOR2 was not able to make headway change.  Vessel 2’s bow struck the stern (rear) side of Vessel 1.
