RedactedNarrative: Operator was in process of launching out of his slip using the rear control station located at the aft deck of the vessel. White in reverse he maneuvered his vessel around the end of the Marina backing into an open area between two docks. He gave the throttle a quick thrust forward before returning to neutral. This gave him time to move to the fly bridge control station. He then disengaged the rear control station and moved to the controls of the fly bridge. Once at the fly bridge he noticed the vessel was still moving in reverse and apparently gaining speed. He was unable to engage the fly bridge control station to make corrective actions. He ran back down to the rear control station as his vessel was making contact with the dock and several vessels. He was unable to gain control of the vessel at the rear station. He then moved into the cabin and was finally able to stop the vessels momentum. This accident resulted in a domino effect damaging 5 other vessels and 300 linear feet of dock and seven pilings in need of being replaced.   
  
  Vessel 6 was in the same vicinity but was not struck or damaged. Officer determined that he could not conclude if the accident was the result of operator error or a mechanical/electrical failure with the throttles. Owner had newly purchased vessel.  Video and witness statements seemed to validate operator's statement he was having issues with the controls of the vessel.
