Navigation Problems USCG Question #1423 (Set 42)

The true course between two points is 041°. Your gyrocompass has an error of 1°W. You make an allowance of 2° leeway for a east-southeast wind. What gyro course should be steered to make the true course good?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 044°pgc

An ESE wind pushes the vessel to the WNW, requiring a 2-degree correction to the right of the desired track (041 + 2 = 043 True). To convert True to Gyro, apply the 1-degree West error (add West error to True). 043 + 1 = 044 PGC. This follows standard Bowditch conversion procedures.
