What is the purpose of the "duty roster" on a vessel?

The purpose of the duty roster on a vessel is to outline crew assignments and responsibilities. This is crucial for ensuring that all operational roles are covered and that each crew member knows their specific duties, which can vary depending on the time of day, mission requirements, or watch schedules. A well-maintained duty roster helps facilitate effective communication among crew members, promotes accountability, and ensures that safety protocols are adhered to at all times.

While tracking fuel consumption, managing equipment inventory, and scheduling recreational activities are important aspects of vessel operation, they do not fall under the main function of the duty roster. The primary focus of the roster is on the allocation of tasks and managing personnel, which is vital for the smooth running of the vessel’s operations.
