Nautical symbols are graphical representations used in maritime navigation to convey important information about water bodies, hazards, and navigational aids. These symbols are standardized in various maritime charts and publications, helping sailors and navigators understand their surroundings and make informed decisions while at sea. Common nautical symbols include buoys, lighthouses, and depth markers. Each symbol has a specific meaning, such as indicating safe passage, warning of underwater obstacles, or showing the location of navigational aids. Understanding these symbols is essential for safe and effective navigation on the water.
