RedactedNarrative: Vessel 2 was moored and unoccupied at the dock when Vessel 1 attempted to back next to Vessel 2 and side-tie to it.  
  
  However, while backing, the starboard stern of Vessel 1 struck the port side rear gunwale of Vessel 2 causing significant cracks to the gel coat and scrapes to the rub rail.  People on the dock and on Vessel 1 pushed off from Vessel 2 following the contact; Vessel 1's operator then reversed into the rocks on the shoreline causing reported damage to Vessel 1's out-drive and propeller.
