RedactedNarrative: This is a single vessel accident. This vessel had two operators; one controlling the helm (Subject1) and one operating the throttles (Subject2 (Operator)). V1 was traveling west in the Gulf of Mexico just north of Marathon. V1 rolled over and was partially submerged upside down. The accident caused Operator to have fatal trauma to his head and face. Occupant 1 sustained a minor concussion and bruised ankle. Occupant  sustained a broken shoulder and ribs. 
  
  Based on the lack of physical evidence it is unclear what caused the vessel to list to its starboard side and eventually roll over. I believe that based on the statements given from the three rear passengers, operator made contact with either the dashboard or the roof of the vessel or possibly both when the vessel rolled over. The GPS downloads showed the vessel reach 70 mph then slow to 50 mph just before the vessel rolled over. The GPS download showed that there was no drastic change in course heading made by Subject1.  
  
  Alcohol was not a factor in this incident. Based on the totality of the circumstances no charges will be filed.
  
   Occupant1 sustained a broken shoulder blade on his right shoulder and several cracked ribs on his right side.; operator: Severe trauma to the head and face.; occupant2 sustained a minor concussion and a bruised ankle.
