You desire to make good 152°T. The magnetic compass deviation is 4°E, the variation is 5°E, and the gyro error is 3°E. A southwesterly wind produces a 4° leeway. Which course would you steer per standard compass to make good the true course?

Question 1 of 27070

🔍 Key Concepts

• True–Magnetic–Compass (T–M–C) relationships and the standard memory aid ("True Virgins Make Dull Company" or similar) • How to apply variation, deviation, gyro error, and leeway in the correct direction and order • Difference between course to steer and course made good

💭 Think About

• Start from the desired true course and work step‑by‑step toward the standard compass course, keeping track of whether you are adding or subtracting each correction • Think about what a southwesterly wind means for leeway: from which side is the wind blowing, and which way will it push your bow? • Compare your final computed psc course to steer with the answer choices and see which one is closest to your calculated value

✅ Before You Answer

• Be sure you know whether east variation/deviation is added or subtracted when going from true to compass • Confirm how gyro error east affects the relationship between gyro heading and true heading • Double‑check that you applied leeway in the correct direction, based on wind coming from the southwest (SW)
