Once the captain headed out onto Table Rock Lake, the vessel encountered a sudden change of weather. Soon after, a tone sounded on one of the vessel’s key safety systems, known as a bilge alarm, according to the NTSB. The video information, including time stamps, remains preliminary, and no cause of the sinking has been determined, the agency said. About 6:50 p.m., the captain briefed passengers on the location of the life jackets and life rings, according to the NTSB timeline. About 6:55, the captain told passengers the vessel was about to leave land and enter the water, and then it did.
