RedactedNarrative: Vessel 1 was attempting to dock in a slip with docked vessels to either side.  As Vessel 1 began cruising forward towards its intended slip, the wind caused it to drift to starboard.  Vessel 1''s operator advanced throttle and attempted to make a U-turn to-port and come around for another attempt.  As Vessel 1 was turning to-port, its starboard engine lost power.  The wind then pushed Vessel 1''s starboard side into the stern of Vessel 2 which was docked to the left of the slip Vessel 1 was attempting to dock in.
