RedactedNarrative: Vessel 1 was 1/4 mile downstream from the Guffie Bridge, It was traveling approximately 8-10 mph upstream. The operator stated that the boat took a dive to the left and he slowed the boat down when that occurred. The operator stated that the boat continued to draw or dive down to the left, causing the left bow to take on water. This filled the boat swamping it and causing it to sink. 5 occupants, none of which were wearing life jackets at the time of the incident, voluntarily left the vessel and swam towards an island nearby. A hiker in the area called 911 at 0921 hours.  She advised that a boat had capsized below Guffie Bridge, and she could hear the occupants yelling for help. Marine patrol deputies were dispatched at 0926 and were en route, arriving to the scene at 0933. All five occupants were transported by boat to the dock at Celebration Park. All refused medical attention. Two male adult occupants then accompanied the Marine deputies back down river to recover floating equipment and search for the boat. Several items were recovered from the river but the boat had sunk - it was not visible. 
  
  After talking with subjects, I determined that the boat was overloaded for its size at the time of the accident. The Gregory's 12 year old daughter, was not wearing a life jacket in the boat, as required by law. Operator will be issued a citation for overloading the vessel and a lifejacket violation.
