General Navigation USCG Question #1830 (Set 57)

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 B — 350°

Per Bowditch plotting standards, the optimal angle of cut for two lines of position to form a reliable fix is ideally 90 degrees, and acceptable between 60 and 120 degrees. A bearing of 350° intersects a 264° bearing at an angle of 86°, providing an exceptionally strong cut.
