RedactedNarrative: Owner A's vessel was secured on a mooring at the time of the accident.  Operator and Passenger of Vessel B had been drinking throughout the day, entered the harbor and moved north easterly along the shore.  Operator B and Passenger B were not wearing PFDs and had only a small flashlight for light.  Passenger B spotted Owner A's vessel and called out several warnings.  Operator B did not hear him and could not see past him.  Vessel B struck Vessel A port side to port side moving at less than 5 knots. 
  
  Vessel B pushed Vessel A down and dragged along the rail destroying parts of the stainless steel rub rail and doing extensive damage to the fiberglass.  The prop of Vessel B caused several cuts along the hull of Vessel A. Vessel B also destroyed Vessel A's VHF antennae and struck the cowling of the outboard totally destroying it.  
  
  The operator and passenger of Vessel B then tied up Vessel B an attempt to hide what had happened. No report was willingly filed.  The Owner B never gave the Operator or Passenger of Vessel B permission to use it.
