RedactedNarrative: Operator reported to me that he was cruising at 20mph and coming southward in the Intercoastal Waterway just passed the Darien River. He struck a submerged object that busted through the hull. They were taking on water very rapidly so he beached the boat on the edge of the marsh to avoid it sinking in the river. He called for assistance on the radio. Seatow responded and assisted him with contacting Tow Boat U.S. of which he is a member. They came and removed Operator and his wife from the vessel. Tow Boat U.S. is supposed to try to float the vessel to Brunswick for evaluation and salvage. 
  
  	The tide was nearly high when the incident occurred. I was on scene at low tide water levels the next morning and could see the damaged, submerged piling that used to be the Red #188 day marker Aid to Navigation. There is currently a floating red can in its place until repairs could be made. The old piling is completely submerged at higher water levels.
  
  	Operator believes the boat will be totaled due to the extreme damage to the bottom of the hull. He had just filled the boat up with fuel at Isle of Hope Marina in Savannah. He stated that his bilges were clean and the fuel tanks were undamaged.
