Nautical Charts CORRECTIONS & UPDATES

Corrections to Charts and Nautical Publications - why its important?

Why do marine charts need to be updated? Nautical Charts are ‘living’ documents. Information affecting the safety of navigation for mariners is constantly being received. Sometimes it is in the form of an individual report of a newly discovered danger, or a buoy or beacon has been moved or removed, while other times the change can be as large as an entire new survey. In all cases, the various national Hydrographic Offices have an obligation to publish details of new and altered information affecting the potential safety of mariners. Equally, many mariners have a legal obligation to apply these updates to their nautical charts having your maritime navigation charts up-to-date is much more than a good idea actually for all vessels, ranging from large cargo ships to racing yachts.

Nautical charts are issued by power of the national hydrographic offices in many countries. These charts are considered “official” in contrast to those made by commercial publishers. Many hydrographic offices provide regular, sometimes weekly, manual updates of their charts through their sales agents

Correcting and upgrading a navigation chart is a constant process. Once a chart is published, constantly changing navigational features and aids or other relevant information have to be promulgated in order to update the ships navigating in those areas.

Updated nautical charts are obviously important to provide navigation safety to all end users

Applying corrections to Charts and Nautical Publications - Notices to Mariners (NtM)

Features shown on charts change, either because they are man made, or due to natural changes. Therefore, it is essential that our charts are corrected, or updated regularly.

The situation at sea changes continuously. The Hydrographic Service monitors changes and publishes the necessary corrections to its publications in order to give mariners information about the current situation. It does so by issuing Notices to Mariners.

Applying corrections to Charts and Nautical Publications - Notices to Mariners (NtM): you can keep your charts and nautical publications up to date using the frequent releases of Notices to Mariners produced by the various national Hydrographic Offices or commercial publishers.

Notices to Mariners (NtM) are corrections to nautical charts and publications. NtM only contain information which is vitally important to safety at sea. Mariners are obliged to keep their products up-to-date with NtM until a new edition is issued. A notice to mariners (NTM or NOTMAR) advises mariners of important matters affecting navigational safety, including new hydrographic information, changes in channels and aids to navigation, and other important data. Over 60 countries which produce nautical charts also produce a notice to mariners. About one third of these are weekly, another third are bi-monthly or monthly, and the rest irregularly issued according to need.

Various ways to update and keep corrected the marine Charts and Nautical Books/Publications onboard your ship vessel:

Weekly Notices to Mariners

Cumulative List of Notices to mariners

Annual Summary of Notices to Mariners

Chart Corrections software and computer

There is an offline database and software in use onboard ships where corrections are supplied in the form of weekly mail attachments. These are used to keep the chart correction database up to date exactly like the paper copy of Weekly Notices to Mariners

Navarea Warnings

Navtex Warnings

Summary of Corrections

A close companion to the Notice to Mariners is the Summary of Corrections. The Summary is published in five volumes. Each volume covers a major portion of the earth including several chart regions and many subregions. Volume 5 also includes special charts and publications corrected by the Notice to Mariners. Since the Summaries contain cumulative corrections, any chart, regardless of its print date, can be corrected with the proper volume of the Summary and all subsequent Notice to Mariners.

Nautical charts corrections 

A naval ship's navigator is responsible for buying and maintaining its nautical charts. A nautical chart, or simply "chart", is a graphic representation of a maritime or flight region and adjacent coastal regions. Depending on the scale of the chart, it may show depths of water and heights of land, natural features of the seabed, details of the coastline, navigational hazards, locations of natural and man-made aids to navigation, information on tides and currents, local details of the Earth's magnetic field, restricted flying areas, and man-made structures such as harbors, buildings and bridges. Nautical charts are essential tools for marine navigation; many countries require vessels, especially commercial ships, to carry them. Nautical charting may take the form of charts printed on paper or computerised electronic navigational charts.

The nature of a waterway depicted by a chart changes regularly and a mariner navigating on an old or uncorrected chart is courting disaster. Every producer of navigational charts also provides a system to inform mariners and aviators of changes that affect the chart. In the United States, chart corrections and notifications of new editions are provided by various governmental agencies by way of Notices to Airmen (NOTAMs), Notice to Mariners, Local Notice to Mariners, Summary of Corrections, and Broadcast Notice to Mariners. Radio broadcasts give advance notice of urgent corrections.

A convenient way to keep track of corrections is with a "chart and publication correction record card" system. Using this system, the navigator officer does not immediately update every chart in the portfolio when a new Notice to Mariners arrives, instead creating a card for every chart and noting the correction on this card. When the time comes to use the chart, the navigator pulls the chart and chart's card, and makes the indicated corrections on the chart. This system ensures that every chart is properly corrected prior to use. British merchant vessels receive weekly Notices to Mariners issued by the Admiralty. When corrections are received all charts are corrected in the ship's folio and recorded in NP133A (Admiralty Chart Correction Log and Folio Index). This system ensures that all charts are corrected and up to date. In a deep-sea vessel with a folio of over three thousand charts this can be a laborious and time-consuming task for the navigator.

Various and diverse methods exist for the correction of electronic navigational charts.

Nautical publications updates

The term nautical publications is used in maritime circles to describe a set of publications, generally published by national governments, for use in safe navigation of ships, boats, and similar vessels.

The nature of waterways described by any given nautical publication changes regularly, and a mariner navigating by use of an old or uncorrected publication is courting disaster. Every producer of nautical publications also provides a system to inform mariners of changes that affect the chart. In the United States, corrections and notifications of new editions are provided by various governmental agencies by way of Notice to Mariners, Local Notice to Mariners, Summary of Corrections, and Broadcast Notice to Mariners. Radio broadcasts give advance notice of urgent corrections. For ensuring that all publications are fully up-to-date, similar methods are employed as for nautical charts.

Various and diverse methods exist for the correction of electronic nautical publications.
