RedactedNarrative: Vessel was being used for fishing at night between the shoreline and Red Day Marker #14 at the entrance to Broad Bay.  The victim vessel was in a No Wake Zone, stowing gear to depart area, and was operating with navigation lights on.  Victim Operator states that he was facing the stern of his vessel when his vessel was struck in the port side of his bow causing substantial fiberglass damage and broken bow rails.  The suspect vessel failed to stop and continued into the Broad Bay area.  The suspect vessel can only be described as a larger sport cruiser style boat due to the lack of light in the area during the night hours and the speed at which it was cruising.  The victim has no injuries and was able to return to his dock.
