You are on course 006°T, speed 16.6 knots. At 0516 you see a light bearing 008°T at a range of 10.2. If you change course at 0528 to leave the light abeam to port at 1.0 mile, at what time will the light be abeam?

Correct Answer: Option D — 0553

Per standard celestial and piloting procedures outlined in Bowditch, account for the elapsed time and distance run between the initial sighting at 0516 and the maneuver at 0528. Projecting the new course to a 1.0 mile port abeam passing distance determines the ETA of 0553.
