RedactedNarrative: Vessel 1 was making a starboard turn towards the dock in process of being docked in slip when it suddenly lost power to its starboard engine; this caused the vessel''s stern to slew to the starboard and towards other vessels docked along o and p docks.  Operator of vessel 1 increased power to port engine and turned his bow to the port, towards the open wakeless water.  As he was operating away from the docks on his starboard side, vessel 1 caught a slide attached to the stern of vessel 2 which was docked in slip.  This contact put a scrape along vessel 1''s starboard side and ripped the slide off of vessel 2.  Vessel 1 continued to turn to port, away from the docks, and struck vessel 3 which was docked in slip.  This contact involved the starboard corner of vessel 1''s swim-deck and the middle of the stern-most edge of vessel 3''s swim-deck and shoved vessel 3 forward in its slip.
