RedactedNarrative: The Owner of Vessel 1 arrived at the dock to prepare Vessel 1 for a fishing trip when it was noted that the motor on Vessel 1 had been struck by an unknown vessel (Vessel 2) resulting in the mounting equipment for the motor on Vessel 1 being damaged as well.  The incident appeared to have occurred sometime between May 22 (the date the damage was reported) and May 6 (the last date that the Owner had been at the vessel's location).  There were no witnesses to the incident, and although measurements and details of the damage were assessed and other vessels in the area where compared for a match, a search of the marina was unable to locate any other vessels that might have been Vessel 2.
