Navigation Problems USCG Question #447 (Set 13)

Your vessel is steering course 243°psc. Variation for the area is 5°E, and deviation is 2°W. The wind is from the south-southeast, producing a 2° leeway. What true course are you making good?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 248°T

Compass 243° + Deviation 2°W = Magnetic 241°. Magnetic 241° + Variation 5°E = True 246°. Wind from the south-southeast pushes the vessel to the north-northwest, adding 2° to the course. 246° + 2° = 248°T. This calculation follows standard Bowditch procedures for determining course made good.
