Introduction<\/h2>\n\n\n\n

Marine buoys are like traffic signs on the water. They help boats travel safely. They show where to go and where not to go. If you understand buoys<\/a>, you can avoid shallow water and hidden dangers.<\/p>\n\n\n\n

This guide will teach you how to read marine buoys. The language is simple and clear. It is perfect for beginners.<\/p>\n\n\n

The Lateral Marking System<\/h2>\n\n\n\n

The lateral system is the most common buoy system. It uses red and green buoys to mark channels.<\/p>\n\n\n\n

There are two main regions in the world:<\/p>\n\n\n\n

    \n
  • Region A<\/strong><\/li>\n\n\n\n
  • Region B<\/strong><\/li>\n<\/ul>\n\n\n\n

    The United States uses Region B<\/strong>.<\/p>\n\n\n\n

    Red and Green Buoys (Region B)<\/h3>\n\n\n\n

    When you are returning from open water to a harbor:<\/p>\n\n\n\n

      \n
    • Keep red buoys on your right side<\/strong><\/li>\n\n\n\n
    • Keep green buoys on your left side<\/strong><\/li>\n<\/ul>\n\n\n\n

      A simple memory trick is:
      \u201cRed Right Returning.\u201d<\/strong><\/p>\n\n\n\n

      Shapes Matter<\/h3>\n\n\n\n

      Color is not the only clue. Shape is also important.<\/p>\n\n\n\n

        \n
      • Red buoys<\/strong> are usually round or cylinder-shaped. They are called Nun buoys<\/em>.<\/li>\n\n\n\n
      • Green buoys<\/strong> are cone-shaped. They are called Can buoys<\/em>.<\/li>\n<\/ul>\n\n\n\n

        If you cannot see the color clearly, look at the shape.<\/p>\n\n\n\n

        Numbers on Buoys<\/h3>\n\n\n\n

        Buoys also have numbers.<\/p>\n\n\n\n

          \n
        • Red buoys have even numbers<\/strong> (2, 4, 6, 8)<\/li>\n\n\n\n
        • Green buoys have odd numbers<\/strong> (1, 3, 5, 7)<\/li>\n<\/ul>\n\n\n\n

          The numbers increase as you move toward the harbor.<\/p>\n\n\n\n

          Cardinal Marks<\/h2>\n\n\n\n

          Cardinal marks show where the safe water is around a danger.<\/p>\n\n\n\n

          They tell you to pass:<\/p>\n\n\n\n

            \n
          • North of the mark<\/li>\n\n\n\n
          • South of the mark<\/li>\n\n\n\n
          • East of the mark<\/li>\n\n\n\n
          • West of the mark<\/li>\n<\/ul>\n\n\n\n

            These buoys are black and yellow. They also have special shapes on top. At night, they flash white lights in special patterns.<\/p>\n\n\n\n

            Cardinal marks are common in Europe and many other countries.<\/p>\n\n\n\n

            \n\n\n\n

            Special Purpose Buoys<\/h2>\n\n\n\n

            Some buoys have special meanings.<\/p>\n\n\n\n

            Yellow Buoys<\/h3>\n\n\n\n

            Yellow buoys mark special areas. These may include:<\/p>\n\n\n\n

              \n
            • Swimming zones<\/li>\n\n\n\n
            • Fishing areas<\/li>\n\n\n\n
            • Research areas<\/li>\n\n\n\n
            • Military zones<\/li>\n<\/ul>\n\n\n\n

              Safe Water Marks<\/h3>\n\n\n\n

              These buoys have red and white vertical stripes.
              They show that the water is safe all around.<\/p>\n\n\n\n

              Isolated Danger Marks<\/h3>\n\n\n\n

              These buoys are black with one or more red bands.
              They mark a danger in a small area.
              The water around them is usually safe.<\/p>\n\n\n\n

              Mooring Buoys<\/h3>\n\n\n\n

              These are used to tie up a boat.
              They are often white with a blue band.<\/p>\n\n\n\n

              \n\n\n\n

              Lights on Buoys<\/h2>\n\n\n\n

              Many buoys have lights for night use.<\/p>\n\n\n\n

              Different light patterns mean different things.<\/p>\n\n\n\n

              Common light types include:<\/p>\n\n\n\n

                \n
              • Flashing (Fl)<\/strong> \u2013 Light flashes briefly.<\/li>\n\n\n\n
              • Quick Flash (Q)<\/strong> \u2013 Light flashes very fast.<\/li>\n\n\n\n
              • Occulting (Oc)<\/strong> \u2013 Light is mostly on but turns off briefly.<\/li>\n<\/ul>\n\n\n\n

                The color of the light is also important.
                Red lights match red buoys.
                Green lights match green buoys.<\/p>\n\n\n\n

                Always check your nautical chart for details.<\/p>\n\n\n\n

                \n\n\n\n

                Sound Signals<\/h2>\n\n\n\n

                Some buoys make sounds in fog.<\/p>\n\n\n\n

                They may ring a bell or blow a horn.
                This helps boats find their position in low visibility.<\/p>\n\n\n\n

                If you hear a sound signal, slow down and check your chart.<\/p>\n\n\n\n

                \n\n\n\n
