🔍 Key Concepts

• Difference between variation and deviation • What causes local attraction on a vessel • Purpose of corrector magnets in or near the binnacle

💭 Think About

• Ask yourself: Does the binnacle correction deal with the Earth’s magnetic field, or magnetic influences on the ship itself? • Which term refers to compass error that is different on every vessel but can be adjusted, versus error that is published on charts? • Think about which error changes when you shift cargo, add new electronics, or change the ship’s structure, and which error stays the same for all ships in the same area.

✅ Before You Answer

• Be clear on the definition of magnetic variation (difference between true north and magnetic north). • Be clear on the definition of magnetic deviation (error caused by the ship’s own magnetism). • Recall that magnets in the binnacle are called correctors and ask: which specific compass error do they correct?
