What does the inner ring of the compass rose show when using a parallel rule?

• A. It shows bearing numbers
• B. It shows depth
• C. It shows landmasses
• D. It shows distances

Answer: (A)

Bearing numbers in degrees are shown on the inner ring. This ring provides the numeric direction values, measured clockwise from north. When you use a parallel rule to plot a course, you align the rule with the line you want to plot and read the degree from the inner ring. That degree is the bearing you would steer relative to north (true or magnetic depending on the chart). The other chart elements—depth, landmasses, and distances—are not read from the inner ring.
