GENERAL - chart layouts, positions, distances, directions and compass.

TOPOGRAPHY - landmarks, ports and coastal land features.

HYDROGRAPHY - tides, currents, depths, nature of the seabed, underwater obstructions, tracks, areas, limits and hydrographic terms.

NAVIGATION AIDS & SERVICES - lights, buoys, fog signals, radar, radio, services and small craft facilities.

SUPPLEMENTARY NATIONAL SYMBOLS Supplementary National Symbols for nautical charts used by the United States and United Kingdom are included at the end of each section.
