You are running coastwise at 14 knots. You sight a lighthouse abeam at 0912. At 0939 the lighthouse is 4 points abaft the beam. What is your distance off at the second bearing?

Correct Answer: Option D — 8.9 miles

Applying the Bowditch special case for a four-point bearing, the distance run between the beam observation and four points abaft the beam equals the distance off when abeam and at the second bearing: 8.9 miles.
