Deck Misc (Supplementary) USCG Q#472 (Set 3)

You are steering 125°pgc. The wind is southwest by south causing a 3° leeway. The variation is 6°E, the deviation is 2°W, and the gyro error is 1°W. What is the true course made good?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 121°T

Apply gyro error (1°W) to gyro course (125°pgc) to get true heading (124°T). Account for southwest by south wind creating 3° leeway to starboard, shifting the true course made good to port by 3°, resulting in 121°T.
