Q

A relative bearing is always measured from __________.

🔍 Key Concepts

• Relative bearing vs. true/magnetic bearing • How bearings are measured on a vessel (reference point and direction) • Difference between references tied to the ship vs. references tied to north

💭 Think About

• Ask yourself: When you are standing on the bridge and call out a contact "at 045 degrees relative," what are you measuring from? • Which options are fixed to the Earth (north references) and which move with the ship? • On a maneuvering board or radar display set to relative motion, what is the usual reference direction for 000°?

✅ Before You Answer

• Identify which choices use the ship as the reference and which use north as the reference. • Remember that relative bearings change when the ship’s heading changes, even if the other object hasn’t moved. • Verify whether a relative bearing can ever be more than 180° and what that tells you about how the circle of direction is laid out.
