You desire to make good a true course of 038°. The variation is 5°E, magnetic compass deviation is 4°W, and gyrocompass error is 4°W. A southeasterly wind produces a 4° leeway. What is the course to steer per standard magnetic compass to make the true course good?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 041°psc
Leeway pushes the vessel downwind. A southeasterly wind pushes the vessel to the northwest, requiring a correction of 4 degrees to the right. Applying the Can Dead Men Vote Twice At Elections mnemonic, the total correction (Variation + Deviation + Leeway) converts the True Course to Compass Course: 038 + 4 (Leeway) - 5 (Var) + 4 (Dev) = 041 degrees PSC.
