You desire to make good a true course of 067°. The variation is 11°W, magnetic compass deviation is 3°E, and gyrocompass error is 1°W. A northwesterly wind produces a 5° leeway. What is the course to steer per standard magnetic compass to make the true course good?

You desire to make good a true course of 067&deg;. The variation is 11&deg;W, magnetic compass deviation is 3&deg;E, and gyrocompass error is 1&deg;W. A northwesterly wind produces a 5&deg; leeway. What is the course to steer per standard magnetic compass to make the true course good?

Accepted Answer

Option C: 070&deg;psc. Working backward from true course 067°: add 11° West variation for magnetic 078°, subtract 3° East deviation for compass 075°. A northwesterly wind creates port leeway, requiring a 5° starboard correction, resulting in 070°psc.
