Your vessel is steering 238°T at 11 knots. At 2304 a light bears 176°T, and at 2323 the same light bears 155°T. What will be your distance off abeam?

Correct Answer: Option D — 8.5 miles

Per standard Bowditch chart work methods, solving the navigational triangle constructed from time, speed, and successive bearings determines the vessel's beam distance off as 8.5 miles.
