RedactedNarrative: Synopsis:
  
  I responded to a medical injury call, which was the result of a boat accident. I conducted an investigation, gathered information and submitted a boat accident report. 
  
  Initial Contact:
  
  The injury occurred when Victim was tubing in the back of Crystal Springs Canyon, being towed by an 18ft Monterey operated by Operator (owned by him). Operator was unable to avoid a rock sticking up above the water, causing Victim to hit the rock in the tube, launching him from the tube. The boat did not hit the rock, only the tube. Subject1 stated they swerved to miss the rock sticking up, but the rope swung around, causing Victim to hit the rock. 
  
  Operator also stated that the boat was going approximately 20-25 miles per hour. He said they hit the tip of the rock, and had been towing the tube in a "big circle". Registration and insurance was current and valid on the vessel involved. They had been camping on their rental houseboat in Crystal Springs Canyon. 
  
  The injuries to Victim included a possible broken wrist, shoulder sprain, lacerations on his foot and swollen left knee.  
  
  Conclusion: 
  
  Based on my investigation, the accident was caused by the inattention of the operator of the vessel (Operator). The unfamiliarity with the area, specifically the back of the canyon was also a factor.  Operator stated that this was the first time they had been tubing in that area. See attached pictures, witness statements, and copy of registration and insurance as well.
