As a vessel changes course to starboard, the compass card in a magnetic compass __________.

Official USCG Answer & Rule Citation

Correct Answer: Option D — remains aligned with compass north

A magnetic compass card is mounted on a pivot and remains aligned with magnetic north due to the Earth's magnetic field. When the vessel turns, the compass bowl and the lubber's line rotate around the card. The card itself does not rotate with the vessel's heading.
