Enroute from Rio to Montevideo, the true course is 215°; the gyro error is 2° west. A north wind causes 3° leeway. What course would you steer per gyrocompass to make good the true course?

Correct Answer: Option B — 220°pgc

A north wind pushes the vessel south, requiring a 3-degree correction to the north (215+3=218T). Applying 2-degree West gyro error (adding error to True to get PGC), 218+2 equals 220 degrees PGC. This ensures the vessel maintains the desired track despite environmental and instrument offsets.
