Nautical Chart Expert and Consultant
A nautical chart is one of the most fundamental and fascinating tools available to the mariner. A chart is a conventional graphic representation of a navigable portion of the surface of the earth. It shows the depth of water by numerous soundings and depth contours, the shoreline of adjacent land, topographic features and geographic names that serve as landmarks, aids to navigation, dangers and other information of interest to navigators. The nautical chart is one of the most essential and reliable aids available to the navigator. It is a work area on which the navigator plots courses, ascertains positions, and views the relationship of the ship or boat to the surrounding area. It assists the navigator in avoiding dangers and arriving safely at his destination.
A nautical chart goes through many layers of analysis, processing and review before becoming published. Once published, a chart can be used as a legal document in a court of law. Not only does the chart provide navigation guidance, but it also summarizes documented features such as geographic and shoreline boundaries, geographic names (including historical documented names), federal regulations, and is supported by U.S. Coast Pilots, both past and present. Historical Coast Pilots are an excellent source of information that outlines the geographic changes that have occurred in coastal and inland areas.
