RedactedNarrative: On June 20, 2016 a single vessel incident occurred near the Panama City Pass East Jetty resulting in severe injury to a juvenile female. A family excursion departed from Porter Park in Lynn Haven, Florida by way of vessel to Panama City Pass East Jetty adjacent to Shell Island. The operator of vessel one (V1) along with his wife, were the only adult occupants for this trip. They took seven juvenile and adolescent age relatives on this boat trip for a day of swimming and playing around the Shell Island area. During the course of the day, the operator anchored the boat and allowed the children to off load and swim to shore. As the afternoon progressed, the sea breeze pushed a moderate chop toward the beach, and the outgoing tide exacerbated the wave height. The boat began to drag anchor and was slowly pulled into the surf zone. The operator was in the process of recovering his passengers onboard, when the victim slipped from the swim platform and became entangled in the outdrive. For several agonizing seconds, the victim attempted to extricate herself from the stern drive lower unit. However, due to wave action and shallow water depth, she was repeatedly slammed to the sandy bottom, lifted several feet then impacted again by wave and wash in and around the boat. The victims cousin eventually was able to pull her from the outdrive and push her up into the boat. The victim suffered multiple deep lacerations to her left leg.  Upon getting the boat free from the surf zone and beach, with assistance from several good samaritan's, 911 was summoned and the operator had to call SEATOW for assistance.  The victim was transported to Bay Medical Sacred Heart Hospital in Panama City. The resulting injuries were severe, with multiple deep lacerations. Victim was attempting to board the anchored vessel from the stern swim platform in 3' - 4' waves in shallow water and slipped from the platform. She became entangled in the outdrive and suffered several severe lacerations to her left upper thigh and buttocks.
