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?

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

Accepted Answer

Option C: 047&deg;psc. Converting desired true course to standard magnetic compass requires working backward through variation (6°E), deviation (12°W), and northerly wind leeway (5°), correctly calculating the required steering course as 047°psc.
