At about 1330 hours on 7/3/2011, I received a phone call from the marina entrance station regarding a PWC accident at Rendezvous Beach.  It was reported that the injured person was being taken from the scene in a white boat with a red top to the marina.  The other people had returned to Rendezvous Beach and the PWCs were rentals.  I notified RICH dispatch to send a ambulance to the marina.  I proceeded from the Blue Water beach area to the marina.

Upon arrival at the marina, the ambulance was at the north courtesy dock.  We decided to take two of the EMTs and go out to intercept the boat.  We located the boat just outside the marina.  I dropped the two EMT's off onto the boat and I escorted the boat to the north courtesy dock.  The EMTs put Operator2 onto a back board, stabilized his left leg, and took him to the waiting ambulance.  OPERATOR2 was transported to Logan Regional Hospital.  I gathered brief information from Subject1 before she left to follow the ambulance to Logan.

I went to Rendezvous Beach and found owner of the rental company at Rendezvous Beach.  He directed me to the location of OPERATOR1 and SUBJECT2.  He interpreted/translated spanish for me as I asked questions of OPERATOR1 and SUBJECT2.  Owner took me to the two PWCs which had been loaded onto a trailer.  I took photos and assessed the damages to determine point of impact, impacting vessel, and impacted vessel.

It was apparent that vessel #1 impacted with the bow of Vessel #2 at @ an 80 to 85 degree angle as the stern of Vessel #1 swung to the right and impacted the left side of Vessel #2 where the sponson of Vessel #1 impacted with the upper left leg of Operator2, the seat, and the console of Vessel #2.
 
I attempted to call Subject1 around 2100 hours on 7/3/2011, but her phone's battery was dying.  I told her I would call her on 7/4/2011.  On 7/4/2011, I again attempted to call Subject1, but had to leave a message on her phone's voicemail.  At about 900 hours on 7/5/2011, I received a phone call from Subject1.  I was able to ask her questions regarding their activities before and at the time of the accident.  She reported that Operator2 had been through surgery to install a titanium rod in his left leg (femur) and would be in the hospital for another day or two.

Based upon the information gathered from the verbal statements, I have made the following determinations regarding this accident.
1.  Both Operator2 and OPERATOR1 had been operating their PWCs in a somewhat close proximity to each other, at a location about 1.5 miles north northeast of the day use beach at Rendezvous Beach.
2.  At a point in their operation, Subject1 told Operator2 to stop his PWC and she informed him that she was uncomfortable with how close OPERATOR1 was operating his PWC to theirs.  She told him to move to an area away from them.  They did not know the exact location of OPERATOR1.
3.  From an idle speed, Operator2 operated his PWC is a fairly tight right hand turn to change his direction 180 degrees and had just barely began to apply throttle.
4.  At a high rate of speed, OPERATOR1 operated his PWC in a manner so as to attempt to spray Mr. and Subject1.  OPERATOR1 was unable to operate his PWC at a safe speed and distance to avoid a collision with the OPERATOR2's PWC.  The point of impact on Vessel #2 was slighlty left of the bow.  As Vessel #1 continued its fast rotation to the right, the right gunwhale of vessel #1 collided with the left side of Vessel #2, impacting with operator2’s left leg (femur).  Vessel #1's momentum took it further up and forward on the port side of vessel #2.  All four passengers were ejected from their PWCs.  After the impact, OPERATOR1 made an apologetic statement to Operator2 where he said he was just trying to spray him.
