RedactedNarrative: Operator1 had been operating his PWC (vessel #1) with his daughter operating a second PWC (vessel #2) on the Yakima River.  While traveling southbound on the river Operator1 stated that was following behind his daughter.  His daughter began to slow down and came to a stop.  Operator1 had very little time to react and as he tried to swerve out of the way, he struck the back of his daughter's PWC.

They were taken to shore where victim was checked by medics and brought to the hospital by private car.  
  
  There was no visible damage to either of the PWCs.
