A maritime navigation charts and publication shows relevant information for sailors and guide them in their movements and approaches to the coast, port facilities, etc. In the past, these types of documents were only available on paper; however, little by little, digital versions have been introduced. This article explains these cards and provides an overview of the information they contain.What are nautical charts?What is a nautical chart? This is a recurring question, especially for those uninitiated in navigation. For someone who has been at the helm of a ship, this document by a safety supplier in Qatar is much more than a "road map" of the sea. Instead of roads, it details water areas, ports, and coastlines. It also includes information on the depth of the seabed, obstructions, restricted areas, recommended routes, and navigation aids such as lights and buoys. The primary purpose of a nautical chart from a safety supplier in Qatar is to provide mariners with up-to-date information to avoid running aground or traveling in restricted waters and to navigate in a manner that is safe for themselves and surrounding ships.
Nautical chart providersA maritime navigation chart shows relevant information for sailors and guides them in their movements and approaches to the coast, port facilities, etc. What do nautical charts show?The essential information they contain is required by all types of navigators. The importance of this information depends, to a greater extent, on the ship's navigational equipment. For example, some of the data in charts and publications contain are as follows.Data for position determination:• Reticle• Magnetic variation• Coastal setting• Land surveying• Land marks
• Sounding contours and depth• Marks on land and sea• Main lines• Radar conspicuous objects• Maritime radio, radionavigation and radiodetermination stations• Radar station limits• Hyperbolic navigation gridsRoute search data:• Cost line• Sounding contours and depth• Navigation hazards• Currents and tidal currents• Names of ocean floor features• Names of ocean divisions, bays, and waterways• Landform names
• Ports, roads, and anchorages• Recommended tracks, traffic lanes, and waterways• Restricted traffic areas• Main brands• Bridges or other free spaces (vertical and horizontal) Data for safety and ease of navigation:• Chart datum• Background nature• Bridges or other free spaces (vertical and horizontal)• Various limits (fishing area limits, customs limits, port limits, etc.)• Military artificial features• Maritime radio, radio navigation, radiodetermination stations, and various other stations (signal stations, pilot stations, etc.) • Port facilities
• Places of clearance by customs authorities• Notes, warnings, comments, etc.Digital nautical charts or paper nautical charts?For some time, both formats coexist together. On the other hand, within the digital typology, it is possible to find scanned or vectorial letters. Some surfers wonder about the convenience of paper or its digital counterpart. It is necessary to attend to different points to properly assess this issue: • Whether the vessel is equipped with a large Electronic Chart Display and Information System (ECDIS), backup computers, and power supply.• If the captain of a ship of fewer than 100 tons has adequate local knowledge.The most important issue for safe operation is related to how this new electronic information is used. The key for the prudent navigator is to view an area at the proper scale. If electronic aids are used, this requirement is vital to have the information as would be the case with a paper letter.
