While on a course of 066°pgc, a light bears 18° on the port bow at a distance of 12.3 miles. What course should you steer to leave the light 4 miles abeam to port?

Correct Answer: Option C — 067°pgc

Using standard Bowditch piloting techniques for parallel index and passing distance off a light, trigonometry applied to the initial bearing and offset range results in a required course of 067°pgc.
