You are steaming on a course of 253°T at 14 knots. At 2329 you observe a lighthouse bearing 282°T. At 2345 the lighthouse bears 300°T. What is your distance off at the second bearing?

Correct Answer: Option B — 5.9 miles

Based on Bowditch navigation principles, solving the triangle formed by the course line and successive bearings gives the distance off at the final observation as 5.9 miles.
