RedactedNarrative: On December 29, 2021, at approximately 2:00PM, Cpl. was notified of a single vessel (LA6137 GL)  incident that occurred off of Alligator point in Lake Borgne. Agent made contact with the operator, and was advised he and two other occupants were awaiting a friend to retrieve them from the marsh bank. Operator stated they had been fishing a pond off Alligator Point. When they attempted to leave, they got stuck. He began maneuvering the vessel through shallow water for several hours attempting to leave the area. At one point he realized the motor was becoming over heated due to several wires smoking/melting. Once successfully out the pond he attempted to maneuver his vessel around Alligator Point to return to the launch. He decided to slow up to approximately 5mph due to his motor overheating from the previous workload in the pond. At approximately 1:15PM the wind and rough weather conditions pushed the vessel closer towards the bank where his prop struck the mud. While attempting to stay clear form the bank, he immediately tried to increase speed causing the motor to go into "Guardian Mode". Without power, the vessel was pushed towards the bank and continued to take on waves until it was swamped and sank. Agent determined no injuries occurred and everyone was safe. Cpl.and Sgt. arrived at the "Yellow Store" launch and documented the vessel a short time after (approx 3:25PM). The middle console remained visible and agents identified they had anchored the vessel. Due to unsafe weather conditions he stated he would remove the vessel later on in the week. SBSO was advised of the incident. All occupants are accounted for. Rough weather conditions is believed to have played a part in this incident.
