sea charts
Navigational ocean maps
Sea charts are maps designed for marine navigation, showing coastlines, water depths, currents, hazards, and other features essential for sailors.
Unlike land maps, they emphasize what lies beneath and upon the water: shoals, reefs, buoys, lighthouses.
The captain consulted the sea charts before entering the harbor.
Also called nautical charts.
