RedactedNarrative: PWC #1 and #2 had passed under the bridge on Highway 6 into the east end of the lake when both came up to power and plane. PWC #1 was leading and operator cut power after turning into the path of PWC #2. Operator #2 had looked over his shoulder to make sure he was clear of other watercraft in the area and did not know that #1 had cut power and was now in front of him. PWC #2 struck #1 on the left side just aft of the middle of the PWC causing damage to the hull under the seat and to the seat. Operator #1 was injured and was helped out of the water and to the property, where first responders and EMS personnel assisted and transported him to the hospital for a laceration and possible broken left leg. Operator inexperience seems to be the main cause of this accident.
