Question 69 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is B **Why Option B (The deck log) is correct:** The deck log (or ship's logbook) is the official record kept by the officer of the watch (OOW) during their tour of duty on the bridge. It is maintained specifically to record day-to-day happenings concerning the navigation, maneuvering, weather, position, and activities related to the ship's operation and the performance of the deck department. It is a continuous, chronological record of the ship's activities. **Why the other options are incorrect:** * **A) The bell book:** The bell book (or engine movement recorder) records the telegraph movements (orders) sent from the bridge to the engine room, detailing changes in engine speed and direction. While related to watchkeeping, it focuses specifically on machinery movements, not general deck department happenings. * **C) A cargo record book:** This book is used exclusively to document the loading, stowage, securing, and discharge of cargo. While often overseen by the deck department, it is a specialized record for cargo operations, not the general day-to-day log of the watch. * **D) The Official Logbook:** This is a legally mandated, formalized record required by the ship's flag state (government). It is used to record major legal or personnel events (e.g., births, deaths, injuries, disciplinary actions, inspections, drills, major equipment failures) and is much less detailed for routine, day-to-day happenings than the Deck Log.
