RedactedNarrative: On 12/18/16, a vessel, LA-8422-EX, powered by a tiller handled outboard, exited the Atchafalaya River and entered Catfish Bayou due to rough water being caused by a strong North wind. Upon entering Catfish Bayou, the vessel became stuck in shallow water and water lilies. 
  
  While the vessel was stuck, a storm passed over with heavy rain fall. All 3 subjects on board the vessel became extremely wet. Due to the temperature being in the 30's and a strong North wind, one of the passengers became hypothermic. 
  
  The vessel operator and one of the passengers managed to free the vessel and leave Catfish Bayou. After leaving Catfish Bayou, the vessel ran aground on a sandbar while attempting to enter the Atchafalaya River. The operator and passenger managed to bail the water out of the vessel and free the vessel from the sandbar. The operator then crossed over to the East bank of the  river to seek shelter at a nearby work site and ran aground again. 
  
  The vessel operator and one of the passengers managed to keep the vessel from taking on too much water and while flagging down another vessel to assist them. The other vessel assisted by placing all three persons onboard its closed cabin vessel with a heater. The assisting vessel then towed the vessel that was in distress back to the Berwick boat launch. 
  
  The passenger that had become hypothermic was transported to Thibodaux Regional Hospital and the other two subjects refused medical attention. Agent does not suspect alcohol or drugs to be contributing factors in the incident. PFD's were onboard the vessel but were not used.
