Nautical charts are oriented with which direction at the top?

• A. North
• B. East
• C. South
• D. West

Answer: (A)

North at the top provides a fixed reference direction for bearings and plotting. Bearings on charts are measured clockwise from north, and the latitude-longitude grid lines align with that direction, so you can plot a course or a waypoint consistently. If you’re using a compass, you may need to apply magnetic variation to convert true north references to magnetic headings, but the chart’s top is still oriented to north. Rotating the chart so that east, south, or west were at the top would change what 0 degrees means and complicate navigation, which is why north is the standard.
