Question 1 of 2066636eea28f7522a1c51a917

At 0815, you change course to 079°T and head for the entrance of Great Salt Pond on Block Island. To compensate for a northerly wind, you estimate a 5° leeway is necessary. What course should you steer per gyrocompass to make good 079°T?

🔍 Key Concepts

• Leeway and how wind from a given direction pushes a vessel off course • Difference between course to make good (CTMG) and course to steer (CTS) • Relationship between true course and gyrocompass course (pgc) when no gyro error is mentioned

💭 Think About

• If the true course to make good is 079°T and the wind is from the north, which way will it tend to push your bow (toward a more southerly or more northerly track)? • To counteract that sideways push, should your course to steer be set slightly into the wind or away from it, and by how many degrees? • Once you adjust for leeway, does anything in the problem tell you to change from true degrees to another reference (like applying gyro error), or can you assume they are effectively the same here?

✅ Before You Answer

• Be clear on which side of your intended track the wind from the north will push you, and adjust your CTS toward the wind. • Apply the full 5° leeway to the 079°T in the correct direction before looking at answer choices. • Verify whether you need to correct for gyro error; if none is given, the true course and gyro course can be treated the same for this problem.
