RedactedNarrative: Operator 1 : Stated I was traveling in line of skis within the rental zone. While I was driving the ski in
  front of me suddenly slowed up. I did not have enough time to get out of the way which then I hit him
  from behind.
  
  Operator 2 : Stated that I was traveling within the rental zone. I noticed a large vessel coming up so I
  slowed down so I didn't hit the wake. All I remember is being struck from behind and flying off the ski
  into the water. The instructor then helped me onto his ski and took me back to the rental place.
  
  Investigation Revealed : Both Vessel 1 and Vessel 2 were traveling North within the marked PWC rental
  zone located in Rainbow Channel, Ocean City NJ. While cruising, operator 2 noticed a large vessel
  approaching the rental zone. At that time operator 2 decided to throttle down to avoid the wake, which
  then Vl struck V2 from behind. The impact of Vl striking V2, caused operator 2 to be ejected from the
  ski into the water. The rental zone instructor was able to remove operator 2 from the water and brought
  to Wally World where he was met by Ocean City EMS. Operator 2 was transported to Shore Memorial
  Hospital in Somers Point with a lower back injury. Operator 1 did not report any injury. Vessel 1
  sustained minor fiberglass damage to the bow. Vessel 2 sustained fiberglass damage to the stern of the
  vessel along with damage to the seat. Operator 1 was issued a careless operation summons in reference
  to the accident.
