General Navigation USCG Question #189 (Set 6)

Which information does the outer ring of a compass rose on a nautical chart provide?

Official USCG Answer & Rule Citation

Correct Answer: Option D — True directions

The outer ring of a nautical chart's compass rose is oriented to True North. This allows for the direct plotting of true bearings and courses. The inner ring, if present, is oriented to Magnetic North, accounting for the local variation at the time the chart was published or updated.
