A vessel heading NNE is on a course of __________.

Correct Answer: Option A — 022.5°

North-Northeast (NNE) is the point located between North (000°) and Northeast (045°). It is 22.5° clockwise from North. Adding 22.5° to 000° yields 022.5°. Proficiency in these standard compass headings is a mandatory requirement for all USCG licensed deck officers to ensure safe and accurate vessel navigation.
