You are on course 344°T and take a relative bearing of a lighthouse of 090°. What is the true bearing to the lighthouse?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 074°
True bearing calculation per Bowditch: TB = TC + RB. Adding the true course of 344° and the 090° relative bearing equals 434°. Subtracting 360° produces the correct true bearing of 074°T.
