RedactedNarrative: Owner of a 40 foot Silverton MY checked on his winterized  vessel  in its marina slip and discovered damage to the bow and rub-rail estimated at $4000.  The NRP investigating officer checked nearby vessels both in the marina and moored nearby for damage.  Potential witnesses in the marina and local area were questioned.  Due to the height of damage, it is likely a large vessel, possibly a pile driver, was maneuvering and hit the bow which was extended beyond the slip.  
   
  The case is closed pending any future leads.
