Your vessel is on a course of 196&deg;T at 17 knots. At 0417 a light bears 218.5&deg;T, and at 0442 the light bears 241&deg;T. At what time and distance off will your vessel be when abeam of the light?

Accepted Answer

Option B: 0500, 5.0 miles. Applying Bowditch piloting procedures for symmetrical relative bearings, the run duration between the two sights equals the time remaining until abeam. This calculates an abeam time of 0500 with a precise radar-verified distance off of 5.0 miles.
