RedactedNarrative: It was common practice for this missing person to tie up his dog at the park and row on to his sailboat on the mooring and return to the park and retrieve the dog afterwards.  It appears the sailboat was prepared to dock to the pier on the port of the vessel as indicated by fenders and fender boards being placed on the port side.  This positioning would also indicate an outgoing tide.  The vessel was found dragging its anchor and dinghy secured to stern of the sailboat it is evident missing person made it aboard the sailboat, prepared it for mooring up to the pier, removed the boat from the mooring and subsequently had to anchor the vessel due to the prop becoming fouled with line.  It is presumed that he entered the water after anchoring the vessel and sometime after making an 8:40pm phone call.  The presence of the overturned dingy would indicate he was in it attempting to possibly free the fouled prop or swamped it in attempt to get back into it once he entered the water.  Victim is still missing and has not been recovered.  It is assumed that he accidentally fell overboard.
