Navigation Problems USCG Question #1391 (Set 41)

You are steering 154° per gyrocompass. The wind is northeast by east, causing 4° leeway. The gyro error is 3° east, variation is 11° west, and deviation is 7°E. What is the true course made good?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 161°T

Converting gyro course to true course involves applying gyro error, variation, deviation, and leeway. A northeast by east wind blowing toward the southwest causes port leeway, resulting in a true course made good of 161°T.
