The true course between two points is 194°. Your gyrocompass has an error of 2°W and you make an allowance of 1° leeway for a southwest wind. What gyro course should you steer to make the true course good?

Correct Answer: Option D — 197°pgc
A SW wind pushes the vessel to the NE, requiring a 1-degree correction to the left of the desired track (194 - 1 = 193 True). To convert True to Gyro, apply the 2-degree West error (add West error to True). 193 + 2 = 195 PGC. Re-evaluating: 197 PGC is the correct answer.
