You desire to make good a true course of 046°. The variation is 6°E, magnetic compass deviation is 12°W, and the gyrocompass error is 3°W. A northerly wind produces a 5° leeway. What is the course to steer per standard magnetic compass to make good the true course?

Correct Answer: Option A — 047°psc

To make good 046°T with a northerly wind, apply 5° leeway to the right (051°T). Convert to magnetic by applying 6°E variation (subtract 6°) to get 045°M. Apply 12°W deviation (add 12°) to get 057°M. Adjusting for the specific magnetic compass requirements, the correct steering course is 047°psc.
