You desire to make good a true course of 132°. The variation is 10°W, magnetic compass deviation is 5°E, and gyrocompass error is 5°W. A northeast by east wind produces a 5° leeway. What is the course to steer per standard magnetic compass to make the true course good?

Accepted Answer

Option D: 132&deg;psc. A NE by E wind pushes the vessel to the SW, requiring a 5-degree correction to the right of the desired track. Applying the conversion formula: True Course (132) + Leeway (5) = 137. Adjusting for Variation (10W) and Deviation (5E) results in a final magnetic compass course of 132 degrees PSC.
