RedactedNarrative: Operator #1 stated to the effect: 
  A large wave went over the bow and then the boat stalled out causing the boat to sink.  The storm rolled in with high winds and rain making it hard for me to control the boat.  I drove the boat close to the marsh knowing there would be shallow water just in case something happen.  Once the wave went over the bow there was nothing we could do.
  
  Investigation revealed: 
  Vessel #1 was in the Mullica River just out front of Chestnut Neck Boatyard located in Port Republic, Atlantic County.  The weather was calling for severe thunderstorms throughout the day and at the time of the incident.  Vessel #1 took on water and sunk due to the weight from the amount of water in the vessel and the see conditions from the storm.  Witnesses / Passengers on the vessel all stated the same and advised a large wave went over the bow.
  
  The cause of the accident was due to the severe thunderstorms that came through the area.  Winds were 50 to 60 kts causing the light weight airboat hard to control.  The vessel then took on water from waves created from the high winds.  No injuries were reported on scene and the owner had SeaTow remove the vessel from the water.
