RedactedNarrative: V1 was approaching the dock from the south side and the operator stated he was unable to slow down because the engine would not go into reverse.  He stated he turned to the starboard but was unable to avoid hitting V2 which was tied to the dock. V1 struck V2, glancing off the outboard. V1 damage was approximately a 4' long scratch on the port side near the stern. V2 sustained damage to the outboard motor, cowling and steering cables.
   
  V1's throttle/reverse was checked and was determined to be functioning properly.
