Question 1 of 2707066636eea28f7522a1c51b138

Enroute from Rio to Montevideo, the true course is 215°; the gyro error is 2° west. A north wind causes 3° leeway. What course would you steer per gyrocompass to make good the true course?

Enroute from Rio to Montevideo, the true course is 215°; the gyro error is 2° west. A north wind causes 3° leeway. What course would you steer per gyrocompass to make good the true course?

🔍 Key Concepts

• Applying gyro error: how to convert between true and gyro courses when the error is west • Leeway from a north wind: which way the ship is pushed and how that affects the required heading • Order of corrections: whether to apply leeway before or after correcting for gyro error

💭 Think About

• Start from the desired true course. Think about whether you must point the ship into or away from the wind to cancel leeway from a north wind. • Decide whether leeway changes the true course made good or the heading you steer, and in which direction (higher or lower degrees). • Once you have the desired true heading, think through how a 2° west gyro error changes the reading on the gyrocompass compared to true.

✅ Before You Answer

• Confirm if north wind causes leeway toward higher or lower true bearings when you are heading around 215°. • Be clear which formula you are using for gyro error: "Gyro least, error east; gyro best, error west" and how that affects the indicated course. • After applying both leeway and gyro error, check whether your final answer should be greater than or less than 215° and by roughly how many degrees.
