Question

While on a course of 349&deg;T, a light bears 13&deg; on the 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?

Accepted Answer

Option A: 349&deg;T. The current distance off is 10.8 * sin(13 degrees) = 2.43 miles. Since the desired distance is 2.5 miles, which is nearly identical to the current distance, no significant course change is required. Maintaining the current course of 349 degrees T ensures the vessel passes at the intended distance.
