Navigation Problems USCG Question #1418 (Set 42)

The true course from point A to point B is 317°. A SSW wind causes a 4° leeway, variation is 6°W and deviation is 1°E. What is the magnetic compass course to steer to make good the true course?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 318°psc

A SSW wind pushes the vessel to the NNE, requiring a 4-degree correction to the left of the desired track. Starting with the True Course (317), subtract 4 degrees for leeway, then apply Variation (6W) and Deviation (1E) using the Can Dead Men Vote Twice At Elections rule to arrive at 318 degrees PSC.
