NOAA National Oceanic and Atmospheric Administration Nautical Chart

The area covered by NOAA nautical charts exclusively encompasses the coastal waters of the United States, representing one of the world's major maritime domains. These official documents are produced by the Office of Coast Survey (OCS), the hydrographic service of the National Oceanic and Atmospheric Administration (NOAA), the U.S. reference authority for maritime and oceanographic navigation since 1807. For any leisure sailor or professional mariner planning to navigate U.S. waters, choosing the appropriate chart is essential for safety and regulatory compliance, enabling precise approaches to the coast and rigorous management of navigational risks.

What is this nautical chart used for?

The value of an official NOAA nautical chart lies in its ability to provide highly accurate hydrographic and oceanographic data to enhance safety at every stage of a voyage.

• Route planning and safety: They are an essential tool for preparing a voyage, whether for sailing, fishing or cruising.

• Bathymetric analysis: The charts show water depths and underwater relief, helping mariners avoid shoals.

• Aids to navigation: They accurately identify navigation marks, lighthouses and buoys required for safe positioning.

• Environmental information: They provide information on currents and tides, as well as potential hazards in the area.

• Operational optimisation: These documents enable mariners to cover many nautical miles, discover safe and attractive anchorages, and manage both coastal and offshore navigation.

Which type of navigator is this chart recommended for?

Nautic Way Maritime Bookshop offers these solutions to all types of mariners navigating U.S. waters.

• Leisure sailors and recreational boaters: For those seeking detailed information to make their boating activities safer.

• Long-distance sailors and skippers: Particularly useful for those crossing the Atlantic or Pacific Ocean towards the U.S. coast.

• Professional mariners and commercial shipping: NOAA charts are suitable for the requirements of commercial navigation.

• Technology-oriented navigators: For those wishing to combine paper charts with Electronic Navigational Chart (ENC) standards, as NOAA is now increasingly focused on this vector format.

Reading and understanding the chart

The effectiveness of NOAA charts relies on a rigorous organisation of data using standardised scales.

• Format and presentation: Paper charts are generally supplied flat and rolled in a tube.

• Various scales: The catalogue includes 1,015 products divided into different coverage areas: coastal (673 charts), nearshore (174 charts), offshore (45 charts) and oceanic (1 chart).

• Depth units: On traditional NOAA paper charts, depths are indicated in fathoms.

• Next-generation printing: To compensate for the discontinuation of traditional charts, Nautic Way uses a system that enables ENC (Electronic Navigational Chart) data to be printed as paper charts, equivalent to the former paper charts but with depths shown in metres.

• Specific areas: The catalogue covers a wide range of areas, including the American Great Lakes, the Gulf of Mexico and the Caribbean Sea.

Reliability, updates and safety

Safety at sea depends on the continuous updating of nautical information, an area in which NOAA is undergoing a major technological transition.

• Continuous updates: Charts are continuously updated by the Office of Coast Survey to ensure the highest possible level of navigational safety.

• End of traditional production: NOAA announced the complete discontinuation of traditional paper chart production as of January 1, 2025.

• Continuity of service: To replace these documents, Nautic Way offers printed charts based on ENC data, updated in near real time from hydrographic databases.

• Printed to order: All charts are printed to order so that the latest available corrections can be incorporated. Due to their rapid obsolescence, they cannot be returned or exchanged.

FAQ

Which NOAA nautical chart should I choose for navigation in the United States?
The choice depends on your navigation area and the required scale, whether coastal for coastal cruising or offshore for longer passages. You can use the interactive chart tool on Nautic Way to select your area precisely.

Is this chart sufficient on its own for safe navigation?
Although highly detailed, a NOAA nautical chart should be used as part of a comprehensive navigation system, ideally supplemented by sailing directions and almanacs for complete risk management.

How often should a NOAA chart be replaced?
With the discontinuation of traditional paper chart production in 2025, it is essential to use the new ENC-based printed charts supplied by Nautic Way in order to have access to the most recent data.

Why are depths sometimes shown in fathoms and sometimes in metres?
Depths are shown in fathoms on original NOAA paper charts, whereas they are shown in metres on the new charts printed by Nautic Way from ENC data.

Can NOAA charts be used with a GPS?
Absolutely. The new paper charts are derived from the same underlying vector databases as Electronic Navigational Charts (ENCs), ensuring consistency with your GPS and navigation systems.
