You are steaming on a course of 114°T at 17 knots. At 1122 you observe a lighthouse bearing 077°T. At 1133 the lighthouse bears 051°T. What is your distance off at the second bearing?

Correct Answer: Option B — 4.3 miles

Using piloting principles outlined in Bowditch, the intersection of the course line, run distance, and bearing angles establishes a distance off of 4.3 miles at the second observation.
