General Navigation USCG Question #1835 (Set 57)

You take a bearing of 313° and 076° of two objects. Which bearing of a third object will give the best fix?

Official USCG Answer & Rule Citation

Correct Answer: Option A — 014°

Per Bowditch, a three-line fix is strongest when bearings are separated by approximately 60 degrees. Given bearings of 313° and 076°, an additional bearing of 014° provides optimal angular separation, creating a well-proportioned triangular cocked hat indicating minimal random observational error.
