RedactedNarrative: After interviewing the operator of the motorboat and getting his statement. As well as interviewing the operator of personal watercraft 1 whom was operating in the area at the time of the accident. It was determined through my investigation that pwc 2 was following pwc 1 travelling south at approximetly 40mph, as they attempted to cut in front of a motorboat that was traveling east. 
  
  Pwc 1 cut in front of the motorboat, this caused the motorboat operator to come off throttle. This caused the bow of the motorboat to rise, at the same time pwc2 struck the left(port) side of the motorboat. 
  
  Pwc2's operator was ejected into the side of the motorboat striking it with his head and body. Pwc2's operator was wearing a us coast guard approved flotation device, causing him to remain floating face down in the water. The operator of the motorboat jumped into the water and turned pwc2 operator over so he was face up. The father of the operator of pwc1, and the operator of the motorboat transported pwc operator 2 back to hammond marina launch ramp. Once there pwc 2 operator was transported directly to university of chicago hospital with a traumatic head injury, right shoulder injury, and right knee injury. 
  
  The accident was not caused by weather conditions. At the time of the accident the wind was relatively calm with 1-2 ft waves. The visibility was also good with no restrictions. Alcohol and drugs were not a factor as well. The motorboat operator did not show any signs of impairment, and there was no alcohol on either the motorboat or the pwc.
