Who must ensure all crew members are familiar with their duties?

• A. Master of the vessel
• B. Chief engineer
• C. Boatswain
• D. Purser

Answer: (A)

The person in charge of a vessel has the primary duty of safety and smooth operation, which includes making sure every crew member knows what they are supposed to do. The master assigns roles, reviews watch schedules, and ensures proper training so that each crew member understands their duties during normal operations and in emergencies. This responsibility covers not just routine tasks but also how the team reacts in drills and real situations, so everyone can act quickly and correctly when needed. While other key crew members—such as the chief engineer, boatswain, or purser—play crucial, specialized roles, they operate under the master’s authority and don’t bear the same overarching obligation to ensure every crew member is familiar with all duties. Thus, the master must ensure all crew members are familiar with their duties.
