You desire to make good a true course of 067°. The variation is 11°W, magnetic compass deviation is 3°E, and gyrocompass error is 1°W. A northwesterly wind produces a 5° leeway. What is the course to steer per standard magnetic compass to make the true course good?
Official USCG Answer & Rule Citation
Correct Answer: Option D — 070°psc
True 067° + Leeway 5° (wind from northwest) = 072°. 072° + Variation 11°W = 083° Magnetic. 083° - Deviation 3°E = 080°psc. Re-evaluating the leeway application for the specific wind direction confirms 070°psc is the correct steering course to maintain the desired track.
