Your vessel is steering course 284°psc, variation for the area is 6°W, and deviation is 3°E. The wind is from the north-northeast, producing a 3° leeway. What true course are you making good?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 278°T
Compass 284° + Deviation 3°E = Magnetic 287°. Magnetic 287° + Variation 6°W = True 281°. Wind from the north-northeast pushes the vessel to the south-southwest, subtracting 3° from the course. 281° - 3° = 278°T. Always verify the direction of leeway relative to the vessel's heading.
