Question 2956 Deck General

The correct answer is A) in the compass deviation log. When an azimuth of the Sun has been taken and the deviation of the standard magnetic compass computed, the results should be recorded in the compass deviation log. This log is the official record of the vessel's compass errors and is used to determine the compass deviation at any given time. Recording the azimuth and deviation in the log allows the watch officer to maintain an accurate record of the compass performance, which is essential for safe navigation. The other options are incorrect because: B) recording on the compass deviation card would not provide a comprehensive log of the compass errors over time, C) the vessel's Official Logbook is used for a different purpose, and D) a Napier diagram is a navigational tool used for a different calculation.
