Marine Accident Brief: Grounding and Sinking of Fishing Vessel Capt. M&M

Executive Summary

On September 18, 2018, at 0532 local time, the fishing vessel Capt. M&M grounded on the east jetty of Sabine Pass, an outlet for the Sabine and Neches Rivers into the Gulf of Mexico, while en route to the channel’s entrance. The vessel subsequently flooded and capsized. All four crewmembers climbed onto the overturned hull, from where they were rescued uninjured by a local law enforcement boat with US Coast Guard coordination. The vessel later sank at an estimated loss of $100,000. Approximately 3,500 gallons of diesel fuel oil on board were not recovered.

Probable Cause

​The National Transportation Safety Board determines that the probable cause of the grounding of the fishing vessel Capt. M&M was the failure of the wheelhouse watchstander to keep a proper navigation watch. Contributing to the sinking was a modification to the watertight collision bulkhead that allowed progressive flooding.
