RedactedNarrative: On 6/25/17 a single vessel boating accident occured in Hillsborough County in Tampa Bay.  V1 was capsized with three people on board at the time of the incident.  It was later determined that the vessel capsized due to water swamping the stern of the vessel. V1 was running on plane.  When V1 came off plane, it took on water from the stern of the vessel.  Due to the V1 swamping, the occupants tried to run to the bow, but when they did the vessel rolled over to the starboard and capsized.  The accident was caused by overloading the stern of the vessel and operator inexperience.
