Q

You are on course 357°T and take a relative bearing of a lighthouse of 180°. What is the true bearing to the lighthouse?

🔍 Key Concepts

• Difference between true bearing and relative bearing • How to convert a relative bearing to a true bearing using your ship’s true course • How to handle bearings that add up to more than 360°

💭 Think About

• If your ship’s head is 357°T and the lighthouse is on a relative bearing of 180°, where is that light located in relation to your bow (ahead, abeam, or astern)? • Mathematically, how do you combine a true course and a relative bearing to get a true bearing? Write the formula in words. • After you combine them, do you need to adjust the result if it is 360° or more?

✅ Before You Answer

• Be sure you are using true course (not magnetic) since the answers are in degrees true. • Remember that relative bearings are measured from the ship’s bow, clockwise 0°–360°. Confirm what 180° relative represents. • After calculating, check if your answer must be brought within 0°–359° by subtracting 360° if necessary.
