RedactedNarrative: On Sunday, August 14, 2016 Operator2 and Operator1 were on Cheatham Lake around river mile 169 riding their friends Sea Doo''s that they had borrowed.  While cruising down river they were both on a straight path of travel with Operator2 just ahead of Operator1.

Operator1 was not injured and her PWC was undamaged.  Operator2 sustained a dislocated hip and a laceration on the chin and was transported to Vanderbilt Medical Center.  Operator2''s PWC had a broke port side mirror and the steering column was damaged.
