RedactedNarrative: The operator was towing a tuber in the area of Salt Run in Matanzas River and the tuber struck a channel marker going approximately 30mph. The tuber suffered a dislocated arm, multiple fractrues in his arm, fractures in his hip, and multiple contusions. 
  
  Witnesses stated that that the operator was towing the tuber on the tube. The tuber struck a piling in the channel of Salt Run. They also stated that they saw the tuber on the tube without a life jacket and he was unconscious when they pulled him in and brought him to shore. 
  
  They both estimated the boat speed around 30mph.  I also asked which channel marker the inner tube and the tuber collided with, they both pointed to red channel marker 4 inside salt run.  They also stated that the operator, along with the other occupants of the Key West did not appear to notice the accident that occurred because the operator kept operating as if he was towing a tuber still.  The other occupants said that the operator didn't realize what happened until the tuber was almost to shore.
