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?
• The standard order of conversions: True–Magnetic–Compass (T–M–C) or the reverse when starting from compass • How to apply variation (W/E) and deviation (W/E) correctly when going from true course to compass course • How leeway (wind pushing you sideways) changes your course to steer compared to desired course made good
• Start from the desired true course 067°T and work step‑by‑step toward a standard magnetic compass course (psc)—what is the correct direction of conversion? • For each correction (variation, deviation, leeway), ask: does a west or east value make the compass course numerically larger or smaller when converting from true to compass? • Think about leeway: if the wind is from the northwest, which way does it push your vessel, and therefore, do you steer into or away from the wind to make good 067°T?
• Be clear on whether you are converting True → Magnetic → Compass, not the other way around • Apply the memory aid (such as “True Virgins Make Dull Companions” or similar) consistently so you don’t add when you should subtract • After getting your compass course, adjust it for the 5° leeway in the correct direction before comparing to the multiple‑choice answers
