RedactedNarrative: Vessel #1 moored at Shelter Island Yacht Club Mooring which parted during a wind shift and gust.  Vessel #1 started drifting through the mooring field and while attempting to gain control collided into the bow of vessel #2.  Vessel #1 then veered to starboard side of vessel #2.  Vessel #1 was then blown farther south and struck vessel #3 on its port side with only minor damage.  Vessel #1 then continued on a southerly course and was hooked by the stern on an empty mooring.  Vessel #1 spent the night at that location until daylight and then vessel #1 was properly moored.  The Shelter Island Yacht Club subsequently found the failed mooring pennant.
