Which navigational error increases when a 18th-century sailing ship experiences significant compass deviation?

💡 Explanation

When a ship experiences compass deviation, local magnetic fields distort the compass reading because metallic objects interfere with Earth's magnetic field, leading to bearing errors. Therefore bearing errors increase, rather than parallax, altitude errors, or dead reckoning issues which rely mostly on sight and estimated speed/time.
