🔍 Key Concepts

• Magnetic variation vs. magnetic deviation – how they differ • Relationship between magnetic north, compass north, and true (geographic) north • Where information about variation is shown on a chart’s compass rose

💭 Think About

• Ask yourself: Which term describes errors caused by the ship’s own magnetic influences acting on the compass? • Which term is concerned with the Earth’s magnetic field at a location, and which with the vessel’s compass itself? • Look at each option: which one clearly refers to something you would normally read from the chart’s compass rose?

✅ Before You Answer

• Verify which quantity (variation or deviation) is shown on the compass rose of a nautical chart. • Check the formal definition of magnetic deviation in relation to magnetic north and compass north. • Confirm whether deviation changes with the vessel’s heading/bearing.
