General Navigation USCG Question #2252 (Set 69)

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

Official USCG Answer & Rule Citation

Correct Answer: Option D — 187°T

According to Bowditch, three-bearing fixes demand optimal angular spacing to avoid large polygon error areas. A bearing of 187 degrees provides the most favorable geometric intersection relative to initial bearings of 313 and 076 degrees, ensuring a reliable and accurate vessel position.
