General Navigation USCG Question #2242 (Set 68)

You take a bearing of 264° of a lighthouse. What bearing of another object would give the best fix?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 350°

Per Bowditch principles of visual fix accuracy, the optimal angle of cut between two position lines is 90 degrees. A first bearing of 264 degrees differs by 86 degrees from 350 degrees, providing a nearly perpendicular intersection that minimizes geometric error and maximizes fix precision.
