Two personal watercrafts (jet skis) were involved in a collision. V01 ramped over V02. One of the subjects involved sustained injuries and needed medical.
At approximately 1840hrs, I arrived on scene. I was met with a Lee County Sheriff’s Office Deputy who confirmed that there were only two PWCs involved, with only one operator on each vessel. Upon arrival, both PWCs were pulled out of the water and were on the beach. The operator of the struck vessel (V2) was still on scene and the operator of the striking vessel (V1) was already transported to the hospital.
I gathered the operator and vessel information, shown as follows:                    
V1 (Striking Vessel)
Yellow PWC
Operator: OP1

V2 (Struck Vessel)
Blue PWC
Operator: OP2
The LCSO deputy had already interviewed OP2 and received a written statement in Spanish (see attached). I decided to interview her again and transcribe her statement into English for her. She could speak English well, but she was limited in her writing. OP2 provided the following statement, and approved of my transcription: 
“I was riding the blue one. The last time I saw him, he was far away about 30 yards. I was going north along the beach, straight. I thought he was stopped. I fell off the left (port) side of the PWC and into the water because I hit a big wave. When I surfaced, I heard someone screaming and began to swim over to help. I believe he hit my jet ski when he got hurt. But I do not know how he got there because he was so far away the last time I saw him. The jet ski went right, I fell into the water left. I did not see the collision.”
There were no witnesses other than the two involved parties. I took pics of the vessel registration, vessel damage, insurance info, rental agreements, and safety course requirements for the livery instructor, and forwarded the information to the investigating officer. There was significant damage to the bow of V2 and damage to the foremost keel of V1 (see pictures), matching the story of OP2’s statement. 
I continued to inspect the livery requirements and safety equipment of the involved PWCs. Upon inspection, it was revealed that the fire extinguisher for V1 was completely rusted and not in serviceable condition. Rental Agency also did not have the required FWC livery permit available for inspection on scene. I informed Officer of these violations.
Based on OP2’s statement and the characteristics of the observed damage on both PWCs, I believe that V2 was driving north, close to beach. The last time she observed OP1operating his vessel (V1), he was stopped approximately 30 yards behind her and was not expecting him to be anywhere near her as she continued on her PWC. While traveling north, OP2 hit a wave, falling into the water on her port side. Her jet ski continued to pivot and face the opposite way. Without her knowing, OP1 was speeding and following too closely and ran into her unmanned PWC. V1 ramped up the port bow of V2, causing the damage seen in the pictures.; OP1:Injuries were a laceration to the left side of his chin., OP1 recieved stitches.
