Question 1 of 2707066636ee928f7522a1c51a3b5

The true course between two points is 337°. Your gyrocompass has an error of 3°E and you make an allowance of 5° leeway for a west wind. Which gyro course should be steered to make the true course good?

Question 1 of 27070

🔍 Key Concepts

• True course vs. course to steer when you have leeway and gyro error • How leeway (from a west wind) affects the actual path vs. the heading steered • How to apply gyro error (3°E) to convert between true and gyro courses

💭 Think About

• Start from the given true course of 337° and decide whether leeway from a west wind will push your vessel to the left (west) or right (east) of your intended track • From that, decide whether you must steer a course that is numerically higher or lower than 337° to compensate for leeway • Next, think about a 3°E gyro error: is the gyro reading higher or lower than the true heading, and how do you adjust the course you want (true) to get the pgc (per gyro compass) you should steer?

✅ Before You Answer

• Be clear on the sign: does west wind cause leeway to port or starboard, and do you correct by steering more into or away from the wind? • Confirm whether an E (easterly) gyro error means "Gyro least, error east" or the opposite, and how that affects the relationship: True vs. Gyro • After applying both corrections, check that the final answer is labeled in pgc (per gyro compass) and that each adjustment was added or subtracted in the correct direction
