The Muster List, in the a maritime world, is a list of the functions each member of a ship crew is required to perform in case of emergency. It is defined in the Chapter III - Part A of the SOLAS Convention.

The Muster List is a critical maritime safety document that details the specific duties and emergency stations for every crew member on a cruise ship. This document is a "gold standard" requirement under the International Convention for the Safety of Life at Sea (SOLAS). It outlines who is responsible for launching lifeboats, who manages fire-fighting teams, and who assists passengers in reaching their assigned Muster Stations. For passengers, the muster list is what dictates where you must go during a "Muster Drill"—the mandatory safety briefing held at the start of every voyage. In 2026, many lines have transitioned to "e-Muster," where you watch safety videos on your smartphone or stateroom TV, but the physical Muster List remains posted in key crew areas and on the back of every cabin door as a permanent reference. This ensures that in the event of an actual emergency, such as a fire or ship abandonment, the crew can execute a highly organized, pre-rehearsed plan to ensure the safety and accountability of every person on board.
