Navigator - Nautical Publications

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.

A convenient way to keep track of corrections is with a Chart and Publication Correction Record Card system. Using this system, the navigator does not immediately update every publication in the library 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 publication, he pulls the publication and its card, and makes the indicated corrections to the publication. This system ensures that every publication is properly corrected prior to use.

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