You are underway on course 059°T at a speed of 13.8 knots. You sight a light bearing 064°T at a radar range of 5.1 miles at 1839. If you change course at 1845, what is the course to steer to leave the light abeam to starboard at 1.0 mile?

Correct Answer: Option C — 050°T

Determine the vessel's position at 1845 after steaming 6 minutes at 13.8 knots. The distance traveled is 1.38 miles. Using the change in bearing and range, calculate the required course change to achieve a 1.0-mile CPA to starboard. Geometric plotting confirms 050°T is the correct heading.
