Your vessel is steering 157°T at 18 knots. At 2018 a light bears 208°T. At 2044 the same light bears 232°T. What will be your distance off when abeam?

Correct Answer: Option B — 14.4 miles

The run distance is 7.8 miles over 26 minutes. Relative bearings are 51 degrees and 75 degrees. Calculating the distance off at the second bearing and projecting to the beam position using the sine of the relative angle results in 14.4 miles, following standard Bowditch navigation principles.
