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?

You are on course 086&deg;T, speed 11.7 knots. At 1013 you see a buoy bearing 088&deg;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?

Accepted Answer

Option B: 1037. Calculate the position at 1019 after a 6-minute run at 11.7 knots (1.17 miles). Using the relative bearing and distance, determine the remaining distance to the abeam point. At 11.7 knots, the transit time for the remaining distance leads to the buoy being abeam at 1037.
