What is the color of the banding on a special mark buoy?

The correct choice indicates that a special mark buoy is identified by its distinct yellow color, often complemented by yellow vertical stripes. This specific color scheme is integral to the IALA Maritime Buoyage System, as it is used to signify marks that do not indicate safe water, channels, or moorings, but rather serve a special purpose such as indicating a specific area, a recreational zone, or indicating other significant information relevant to navigation.

These special marks differentiate themselves from other buoy types, and their vibrant yellow coloration ensures they stand out in various maritime environments, which may include busy shipping lanes or recreational areas where awareness of navigational hazards or specific zones is crucial. In maritime navigation, using correct buoy characteristics is key for safety and effective route planning, emphasizing the importance of recognizing the attributes of each buoy type.
