Navigation Problems USCG Question #434 (Set 12)

Your vessel is steering 195° per standard magnetic compass. Variation for the area is 13°W, and the deviation is 4°E. The wind is from the west-southwest, producing a 2° leeway. Which true course are you making good?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 184°T

Convert compass to true: 195°psc + 4°E (Dev) = 199°M. 199°M - 13°W (Var) = 186°T. A west-southwest wind pushes the vessel to the east, requiring a 2° leeway correction to the west. Subtracting 2° from 186°T results in a true course made good of 184°T.
