Your vessel is on a course of 107&deg;T at 16 knots. At 0403 a light bears 129.5&deg;T, and at 0426 the light bears 152&deg;T. At what time and distance off will your vessel be when abeam of the light?

Accepted Answer

Option B: 0442, 4.3 miles. Calculating running fix parameters for an object passing abeam utilizes elapsed time matching the interval between symmetrical relative bearings. The resulting navigation solution yields an abeam time of 0442 and a charted distance off of 4.3 miles.
