RedactedNarrative: Operator1 had backed vessel 1 out of slip and was turning to port (to the north) when the wind gusted hard, pushing vessel 1 forward and to starboard.  
  
  Vessel 2 was docked in slip, the next slip to the north.  Vessel 1''s  starboard-side rear-corner made contact with the slide that was mounted on the stern of vessel 2 and ripped that slide free from its mountings.  Vessel 1 suffered a 2-3 inch tear in its shade screening.  Vessel 2''s only damage was the slide being torn free of its mountings.
