You are on course 086°T, speed 11.7 knots. At 1013 you see a buoy bearing 088°T at a range of 4.8 miles. If you change course at 1019 to leave the buoy abeam to port at 1.0 mile, at what time will the buoy be abeam?

Correct Answer: Option D — 1037

Applying Bowditch relative motion and running fix principles, account for the course and speed changes between the initial observation at 1013 and the course change at 1019. Projecting the vessel's movement to the abeam position at 1.0 mile yields an abeam time of 1037.
