You desire to make good 152°T. The magnetic compass deviation is 4°E, the variation is 5°E, and the gyro error is 3°E. A southwesterly wind produces a 4° leeway. Which course would you steer per standard compass to make good the true course?

Correct Answer: Option A — 147°psc

Apply leeway and compass corrections using the mnemonic 'Can Dead Men Vote Twice At Elections'. To make good 152°T with 4° leeway (wind from SW pushes vessel to NE, so steer 4° left), the required course is 148°T. Converting 148°T to PSC using 4°E deviation and 5°E variation yields 147°psc.
