Your vessel is on a course of 052°T at 16 knots. At 0916 a light bears 078.5°T, and at 0927 the light bears 097°T. At what time and at what distance off will your vessel be when abeam of the light?

Correct Answer: Option B — 0938, 2.9 miles

Calculating the distance run between bearings (2.93 miles) and applying the relative bearing trigonometry, the distance off at the second bearing is 2.9 miles. The time to reach the abeam position is determined by the remaining distance to run divided by speed, resulting in 0938.
