182. 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?

The ship traveled 6.3 nautical miles in 27 minutes at 14 knots. A bearing change of 4 points abaft the beam creates a 45-45-90 triangle, where the distance off at the second bearing is the hypotenuse. Therefore, the distance off is 6.3 multiplied by the square root of 2, which equals 8.9 nautical miles.
