You are steaming on a course of 025°T at 15.5 knots. At 0645 you observe a lighthouse bearing 059°T. At 0655 the same lighthouse bears 075°T. What is your distance off at the second bearing?

Correct Answer: Option B — 5.3 miles

Standard Bowditch piloting procedures for a running fix dictate calculating the run along the course line between bearings, resolving the exact radar or visual distance off as 5.3 miles.
