RedactedNarrative: On 07/28/18 at approximately 1341hrs, we were advised of an incident near Roy Creek that involved CPR in progress from a PWC accident. Upon arrival at Keenwick W Drive, I was advised that O-1 Operator1 had already been placed into an ambulance. Upon arrival at AGH, I was advised that O-1 Operator1 was pronounced deceased at 1441hrs at AGH. 
  
  During my investigation I learned that the family rented PWCs from Island Watersports in Fenwick Island DE. Island Watersports is located just inside Delaware  north of the Maryland State Line. While riding the PWCs at approximately 1328hrs Operator1 began making a counter clockwise turn and Operator2 was making a north bound clockwise turn at which point the two PWCs one operated by Operator1 and the other Operator2 collided. 
  
  This occurred approximately 150-200 yards north of the MD/DE stateline in Delaware waters. The bow of the PWC # DL327 AN being operated by Operator2 struck the port side just below the handle bar of the PWC # DL 323 AN being operated by Operator1. The initial impact was directly in the area where a rider commonly places their left leg while operating a PWC. As a result of the impact Operator1 was ejected from his PWC into the water. He had injuries from the left foot through the head. As a result of the high speed point of impact being on Operator1s left leg area there was a partially amputation to his left leg near the knee. Operator1 was ejected by some statements 15 to 20 feet into the air before coming to rest in the water.
  
  He was removed from the water by a Good Samaritan vessel with help from his sons. The Good Samaritan applied a tourniquet to his leg using a dock line. They began CPR and transported him to shore. Upon reaching Atlantic General Hospital in Berlin Maryland Operator1 was pronounced deceased at 1441hrs.The Maryland ME report was completed on 07/29/18 and listed the manner of death as “ACCIDENT” with no evidence of drowning. The injuries were consistent with port side high speed impact with another vessel. 
  
  His injuries included multiple abrasions, contusions and lacerations of the skin, subgaleal hemorrhage and subarachnoid cerebellar hemorrhage, fractured sternum, left ribs fractured, mesenteric hemorrhage, lacerated aorta with marked periaortic soft tissue hemorrhage, left hemothorax, fractured pelvis with marked peripelvic soft tissue hemorrhage and hemorrhage tracking into scrotum, lacerated bladder, fractured tibia and fibula with near amputation of left leg at the knee and a fractured left femur. No drugs or alcohol were present. (See full ME Report for further)  
  
  Causes 
  #1 Island Watersports (IWS) failed to provide the required State of Delaware Rental forms which would have required Operator2 to provide proof of taking a state or NASBLA approved boating safety course, which he did not have. IWS followed the Maryland NRP rental laws and testing even though they were partially operating in Delaware. 
  
  #2 High speeds, high RPMs, while making turns which resulted in the collision of the two PWCs, displayed that neither Operator2 nor Operator1 maintained a proper lookout leading up to the incident. 
  
  #3 Operator2 being on the starboard side of his father Operator1 would have made Operator1 the give way vessel and Operator2 the stand on vessel, which Operator failed to give way resulting in a collision. 
  
  #4 Operator inexperience. Prior to 07/28/18 Operator2 had no PWC or vessel operation experience and had not taken a state or NASBLA approved boating safety course. Operator1 had very limited PWC/Vessel operation experience as I was advised maybe once before he had operated a PWC. Overall operator inexperience on a vessel, inexperience on the specific PWCs and lack of proper safety courses played a major role in the collision of Operator2 and his father…
