Your vessel is on a course of 103°T at 14 knots. At 1918 a light bears 129.5°T, and at 1937 the light bears 148°T. At what time and at what distance off will your vessel be when abeam of the light?

Correct Answer: Option D — 1956, 4.4 miles

Executing standard piloting calculations per Bowditch, the time interval and course made good yield the distance run between bearings. Solving the relative bearing geometry determines the vessel will reach the abeam position at 1956 at a distance of 4.4 miles.
