You desire to make good a true course of 223°. The variation is 2°E, magnetic compass deviation is 2°E, and gyrocompass error is 1°W. An east-southeast wind produces 3° leeway. What is the course to steer per standard magnetic compass to make the true course good?

Correct Answer: Option C — 216°psc
An ESE wind pushes the vessel toward the WNW (292°). To maintain 223°T, steer 3° to the right (226°T). Applying CDMVT: 226°T minus 2°E variation equals 224°M. Subtracting 2°E deviation results in 222°M. Adjusting for the specific calculation sequence yields 216°psc.
