RedactedNarrative: V1 was approximately four miles west of Red Fish Pass in the Gulf of Mexico. The subjects were attempting to anchor the vessel at a reef, but the anchor kept dragging. Once the vessel's anchor caught the bottom, the vessel listed to one side taking a large wave over the gunnel. At this point, the vessel was swamped and sitting low in the water. Due to the rough sea conditions, the bilge pump could not keep up with the water flooding the vessel. The owner of the vessel cut the anchor line. At some point, the anchor line became wrapped up in the propeller, and V1 capsized. The five subjects in the vessel climbed on top of the hull and waited for emergency response. The subjects on V1 did not report any injuries at the scene. The owner of V1 made arrangements with a private source to have the vessel removed from the water.
