You desire to make good a true course of 129°. The variation is 7°E, magnetic compass deviation is 4°E, and gyrocompass error is 2°W. An easterly wind produces a 4° leeway. What is the course to steer per standard magnetic compass to make the true course good?

Correct Answer: Option D — 114°psc

Working backward from true course to standard magnetic compass course requires reversing variation, deviation, and leeway. Applying the corrected set of magnetic and compass errors yields a steering course of 114°psc to successfully counteract wind and magnetic variation.
