What is the purpose of a deck log entry?

• A. To measure engine performance
• B. To document watch changes, weather, and significant events for safety and accountability
• C. To calculate fuel efficiency
• D. To write cargo manifests

Answer: (B)

A deck log entry serves as the written record of watch changes, weather observations, and significant events on the vessel, ensuring safety and accountability. By documenting who is on watch and when, along with the current weather, sea state, and any notable occurrences (like changes in course, near misses, equipment issues, or safety drills), the crew creates a traceable history of operations. This helps with situational awareness, continuity if the watch is handed over, and later review or investigations if something goes wrong. Other tasks like measuring engine performance, calculating fuel efficiency, or writing cargo manifests are handled in different logs or documents specific to those areas, not the deck log’s primary purpose.
