RedactedNarrative: On 6/22/14 at approximately 3:15pm a boating accident occurred 300 yards south of the sandbar on lake wylie in charlotte, nc. This was a two-boat incident involving a pair of new unregistered yamaha pwcs with 250 hp motors. One was a 2011 model and the other a 2014 model. Both vessels were owned by the same individual. Vessel 1 was operated by operator1 and vessel 2 by his sister in law, operator2. Operator1 was slowing to a stop when operator2 lost control striking the right side of his vessel. 
  
  On this day, operator1 drove to buster boyd boat access area to try out the two new pwcs he had purchased four days earlier. The weather was nice and he brought operator2 along to enjoy this day. He launched both pwcs from the access area and planned to teach operator2 how to operate one as she had never ridden a pwc before. They spend a minimal amount of time in the no-wake zone in front of the boat ramp so operator2 could practice the controls of the pwc. This left operator2 with only a few minutes of operating experience. Then they decided to head north to the sandbar to see how many people were there and what was going on. 300 yards prior to reaching the sandbar, operator1 turned right and slowed down before arriving at their destination to speak to operator2. Operator2 let off the throttle to slow down. Because of her lack of experience, she was unaware a pwc jet drive continues to move in a straight line if not under power. This caused it to strike operator1 in the right rear panel. The impact sent operator2 forward and across operator1's pwc landing her in the lake. The initial impact of the pwc's injured operator2's right arm and leg. Both operator2 and operator1 were wearing uscg approved life jackets. Operator1 helped operator2 out of the water, seeing she was injured, and assisted her in returning to the boat ramp they came from. The weather was clear and sunny. The air temperature was 88 and the water temperature 87. The lake was rough due to large vessels creating 2 to 3 ft wakes. 
  
  It appears operator inexperience is the key factor in this incident. Operator2 had no formal boating certification and only a few minutes of training in operating this vessel earlier in the day. This incident occurred after operator2 released the throttle making it unable to turn or be maneuvered all while being too close to operator1. Operator2 was charged with careless and reckless operation and operating a motorboat by persons born after 1/1/8 without completing a boater safety course. There was no alcohol involved in this incident.
