Deck Navigation (Supplementary) USCG Question #611 (Set 1)

Which statement about the gyrocompass is FALSE?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Its accuracy remains the same at all latitudes.

Gyrocompass accuracy is highly dependent on latitude because the directive force decreases as the vessel moves toward the poles. At high latitudes, the compass becomes sluggish and susceptible to errors caused by ship motion, making the statement that accuracy remains the same at all latitudes technically false.
