🔍 Key Concepts

• Difference between true bearing and relative bearing • How to measure relative bearings from the ship’s bow (000° at dead ahead) • How to combine course steered and relative bearing (when to add or subtract)

💭 Think About

• If your bow is pointing 030°T, what direction (in degrees true) is straight ahead of you? • A lighthouse is 45° on your starboard bow. In degrees, what angle does that make from true north? • Should a relative bearing on the starboard side usually be added to or subtracted from the ship’s heading to get the true bearing?

✅ Before You Answer

• Confirm that relative bearing is measured from the ship’s bow, clockwise from 000° to 360° • Check whether the lighthouse is to starboard or port based on the given relative bearing • After combining course and relative bearing, ensure your result is between 000° and 359° (use 360° correction if needed)
