🔍 Key Concepts

• Function of the lubber’s line on a standard magnetic compass card • Difference between heading and north (magnetic/compass) • How we read a compass heading from the helmsman’s position

💭 Think About

• Ask yourself: When you stand at the helm and look at the compass, what exactly are you aligning with the lubber’s line? • Does the lubber’s line move with the ship, or does it stay fixed relative to north? What does that tell you about what it represents? • Which option describes something that is unique to your own vessel’s orientation, not a fixed direction on the earth?

✅ Before You Answer

• Be clear on the difference between the ship’s heading and the direction of north. • Remember that magnetic north is a point on the earth, not a mark that moves with the vessel. • Confirm that the lubber’s line is a fixed reference mark on the ship against which you read the compass scale.
