RedactedNarrative: On 09/02/19 at approx. 14:45 CST Operator2  and Operator1 were operating PWC's (jet Ski's) on Rough River Lake.  Operator2 and Operator1 were in Grayson Co. around the Cannon's point area of the lake.    Operator1  was operating vessel  (Reg # KY 0747UF)  Operator1 stated he was following  vessel  (KY 0553LY), operated by Operator2. Operator2 suddenly turned to her port or left side and Operator1 was unable to avoid a collision.  
  
  Operator2 had one passenger on her vessel.  Operator1 ran the starboard or right side of his vessel down the port or left side of Operator2's vessel knocking both occupants into the water.  A passer byer stopped to assist.  The unknown passer byer transported them to the boat ramp at Cannon's point where EMS met them.  Operator2 was uninjured but Victim suffered a broke left wrist, and was transported to Twin Lakes Regional Hospital.   Neither Operator1 nor Operator2 sustained injuries, but both vessels were damaged.  Vessel 1 operated by Operator2 was totaled, and Vessel 2 operated by Operator1 sustained minor damage to starboard or right side. 
  
  Operator2 stated that she did not see Operator1 when she turned to her left.  Operator1 stated he was in Operator2s blind spot and did not have time to react when she turned.  Operator2 who was 15 years old and had an 11 year old passenger did not have a Boater Education permit and was in violation of KY KRS.  Operator1 was given a field sobriety test and had no indicators of impairment. 
  
  It is my opinion through experience and training that the major contributing cause of this incident was Operator2's inattention.
