RedactedNarrative: Operator entered fairway of harbor heading to the fuel dock.  As the vessel got near the fuel dock, witnesses report that the vessel seemed too fast for the fuel dock docking.  
  
  The vessel completed two circles under power, struck the fuel dock, and then exited the harbor running over east break wall rocks.  Operator advised his steering had malfunctioned. 
  
   A mechanic came aboard to assist, and confirmed that the electronic steering was not responding and showed signs of a stripped gear.  The port engine was found not to respond to any inputs from the helm.  Vessel owner had just purchased the vessel approximately one week ago.  His wife was the only other person on board. No injuries were reported.
