Navigation Problems USCG Question #15 (Set 1)

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?

Official USCG Answer & Rule Citation

Correct Answer: Option A — 197°pgc

To counteract a southwest wind causing leeway, the vessel must head into the wind. Applying gyro error in reverse (west error added) converts the true course into the proper gyrocompass course to steer.
