RedactedNarrative: Unit 1 was entering Shem Creek and attempting to dock when the operator realized that his reverse gear was not working.  Tide was coming in and he attempted to slow momentum as best he could.  
  
  During the process he struck Unit 3 and then careened off of it into Unit 2, where he subsequently came to rest.  All 3 Units were damaged/  Unit 2 and Unit 3 were unoccupied and tied to the dock.  There were no injuries.
