Which risk increases when attempting to maintain a consistent ship's heading solely using a magnetic compass in the 18th century?

💡 Explanation

Magnetic compass needles will deflect due to the ship's iron content; this is compass deviation. Because early vessels lacked degaussing, deviation errors could be significant undermining navigation accuracy, therefore, the risk of incorrect heading increases rather than relying on other methods.
