Your vessel is steering course 149°psc, variation for the area is 13°E, and deviation is 4°E. The wind is from the northeast, producing a 4° leeway. What true course are you making good?

Correct Answer: Option D — 170°T

Applying compass corrections (13°E variation and 4°E deviation) to the 149°psc heading establishes the magnetic and true courses. Factoring in a northeast wind causing 4° of leeway determines the true course made good is 170°T.
