🔍 Key Concepts

• Leeway and which direction it is applied when the wind is from the south • Relationship between true course (T), compass course (psc), and total corrections (variation, deviation, leeway) • Standard sequence: "true–magnetic–compass" and the signs (+/–) of each correction

💭 Think About

• If the desired track is 079°T and the wind is from the south, will the vessel be pushed to the north or to the south of that track? How do you adjust your heading to counter that? • Think about whether you should add or subtract the 3° leeway from the desired true course to get the course to steer (CTS) before applying compass corrections. • Work through the full conversion: start with 079°T, apply leeway, then apply variation and deviation (assume they’re built into the problem). Which choice is closest to your computed psc?

✅ Before You Answer

• Be clear which direction the southerly wind is coming from, and which way it sets you. • Confirm whether leeway is applied to get from course made good (CMG) to course to steer (CTS), and whether a correction to the left or right is needed. • Check that the final answer is a per standard compass (psc) course, not a true or magnetic course.
