Description: Lateral marks are visual signals used in maritime navigation to indicate the sides of navigable channels. These marks are essential for navigation safety, as they help boats identify the correct course and avoid running aground in hazardous areas. Typically, lateral marks are presented in the form of buoys, posts, or fixed signs, and their design and color vary according to the regulations of each country or region. Generally, the buoys on one side of the channel are of a specific color, while those on the opposite side have a different color, allowing navigators to quickly discern the direction they should navigate. These marks are crucial not only for navigation in inland waters, such as rivers and lakes, but are also used in coastal waters and ports. Correct interpretation of these signals is vital to avoid accidents and ensure safe transit in aquatic routes. In summary, lateral marks are a fundamental component of the maritime signaling system, providing clear and concise information to navigators about the configuration of channels and the safety of their trajectories.
History: Lateral marks originated from the need to enhance safety in navigation, especially in areas where channels are narrow or hazardous. Throughout history, different cultures have used various methods to signal safe routes, from stacked stones to lighthouses. However, it was in the 19th century that lateral marks were standardized, particularly with the creation of the buoy system in the United Kingdom and its subsequent adoption in other countries. In 1972, the International Conference on Maritime Signaling established clearer and more uniform standards for lateral signaling, facilitating international navigation.
Uses: Lateral marks are primarily used in maritime navigation to guide vessels through channels and safe routes. They are essential in rivers, lakes, ports, and coastal waters, where visibility and safety are critical. Additionally, these marks help navigators identify the boundaries of navigation zones and avoid hazardous areas, such as sandbanks or submerged rocks. They are also used in planning maritime transport routes and managing aquatic traffic.
Examples: An example of lateral marks is the red and green buoys found in navigation channels of rivers, where red buoys indicate the starboard side and green buoys indicate the port side. Another example is the fixed signs in ports that indicate docking areas and entry and exit routes for vessels. These marks are internationally recognized and are fundamental for navigation safety.
