What is the role of 'lookout' and watchkeeping at sea?

• A. To compute celestial navigation fixes.
• B. To monitor the surroundings continuously and be ready to act.
• C. To keep the engine room informed of speed changes.
• D. To ensure cargo operations in port.

Answer: (B)

A proper lookout and watchkeeping are about constant awareness of the vessel’s surroundings to detect other ships, hazards, lights, marks, and weather changes in time to act to prevent danger. The bridge watch ensures there is always someone scanning, listening, and ready to take action—alter course, reduce speed, or communicate with others—when there’s any risk of collision or other hazard. This duty relies on sight and hearing, and on using aids like radar and AIS, but a human lookout is essential for interpreting what those tools show and maintaining situational awareness. Lookouts must be maintained around the clock with appropriate rest to prevent fatigue, and their importance grows in restricted visibility. The aim is safety and collision avoidance, not tasks like celestial navigation fixes, engine-room communications, or cargo operations.
