When an azimuth of the Sun has been taken and the deviation of the standard magnetic compass computed, the watch officer should record the results __________.
• Compass deviation log vs. deviation card – what each is used for on board • Purpose of taking an azimuth of the Sun with the standard magnetic compass • Which records are for ongoing observations vs. permanent reference data
• Ask yourself: when you compute a new deviation from an actual observation, is this something you update regularly or only when a full swinging of the ship is done? • Think about which option is designed as a running record that can show how deviation changes over time on different headings. • Consider: which document would a navigator consult to see past compass checks taken during different voyages?
• Identify which choice is specifically intended for logging individual compass checks/observations. • Distinguish between a formal ship’s legal logbook and a navigation instrument record. • Verify which item is normally prepared by a compass adjuster and posted near the compass as a reference card, not as a running record.
