What is the compass course of a vessel heading ESE?

Correct Answer: Option A — 112.5°

East-Southeast (ESE) is located between East (090°) and Southeast (135°). It represents the point 22.5° clockwise from East. Adding 22.5° to 090° results in 112.5°. Proficiency in these compass points is critical for maintaining accurate navigation and complying with standard bridge watchkeeping procedures.
