RedactedNarrative: On Wednesday, January 26, 2022 at approximately 5:00 p.m. Operator1 was operating LA 8538GH, a 31ft Mainship, in the Delcambre Canal.  At this time, Operator1 heard a grinding noise coming from the starboard engine, like something was attached to the propeller.  Operator1 shifted the engine from forward to reverse a couple times to try and free the propeller.  At this point, Operator1 noticed the stern starting to take on water rapidly.  Before Operator1 could turn LA 8538GH back to the dock, the vessel sunk in the Delcambre Canal.  Operator1 was not wearing a PFD at the time of this boating incident.  Also, alcohol or drugs didn't appear to be a contributing factor in this boating accident.
