RedactedNarrative: Vessel one LA 9303 FT (18' Custom aluminum boat with 140 hp Suzuki/ remote steering) was being operated by operator and had two passengers on board. Vessel one was traveling at idle speed heading west on Grand Bayou towards Calcasieu Lake. Vessel one came up to the Grand Bayou weir. There was a strong current estimated at ten miles per hour heading out the weir into Calcasieu Lake. 
  
  As vessel one maneuvered closer to the weir to pass through the boat passage, the current was rocking vessel one from side to side. Operator then put vessel one in reverse to back vessel one out of the current. The strong current then pushed vessel one into a cable that was connected to a bouy next to the weir. Operator then put vessel one in forward and turned hard to starboard to get away from the cable. The strong current then pushed vessel one into the weir and pinning it against the weir blocking the boat passage. Vessel one instantly started to take on water and flood. Vessel one then capsized and later sank. PFD's were on board, but not used. There was no impairment observed on the operator.
