What is the compass course of a vessel heading SSE?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 157.5°
South-Southeast (SSE) lies between South (180°) and Southeast (135°). Specifically, it is one point (11.25°) clockwise from South. Subtracting 22.5° from 180° yields 157.5°. As outlined in Bowditch, understanding the 32-point compass system remains a fundamental requirement for all USCG licensed deck officers.
