Vessel 1 was close-hauled on a starboard tack in a crossing situation with Vessel 2 on a port tack.  After the Operator of Vessel 1 hailed the Operator of Vessel 2, the Operator of Vessel 2 indicated (verbally) that he would pass behind the stern of Vessel 1.  The Operator of Vessel 2 failed to accomplish this maneuver and instead struck Vessel 1 on the port side near the stern.
