You desire to make good a true course of 223°. The variation is 2°E, magnetic compass deviation is 2°E, and gyrocompass error is 1°W. An east-southeast wind produces 3° leeway. What is the course to steer per standard magnetic compass to make the true course good?

Question

You desire to make good a true course of 223&deg;. The variation is 2&deg;E, magnetic compass deviation is 2&deg;E, and gyrocompass error is 1&deg;W. An east-southeast wind produces 3&deg; leeway. What is the course to steer per standard magnetic compass to make the true course good?

Accepted Answer

Option A: 216&deg;psc. An ESE wind pushes the vessel to the WNW, requiring a 3-degree correction to the right of the desired track. Applying the conversion formula: True Course (223) + Leeway (3) = 226. Adjusting for Variation (2E) and Deviation (2E) using the Can Dead Men Vote Twice At Elections rule results in 216 degrees PSC.
