While on a course of 349°T, a light bears 13° on your starboard bow at a distance of 10.8 miles. What course should you steer to pass 2.5 miles abeam of the light, leaving it to starboard?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 349°
The light is already 13 degrees on the starboard bow, and the desired passing distance is 2.5 miles at a range of 10.8 miles. Since the sine of the angle (2.5/10.8) is approximately 13.3 degrees, the current course already aligns with the required passing distance, necessitating no change in course.
