What color typically indicates a port lateral buoy?

In maritime buoyage systems, particularly under the IALA (International Association of Lighthouse Authorities) guidelines, the color red is established as the indicator for port lateral buoys. These buoys serve the essential purpose of marking the left side of a channel when approaching from the sea towards the shore. The significance of this convention lies in its alignment with the commonly accepted navigational practices; mariners use this system to ensure safe passage and to avoid hazards.

Understanding the color coding is crucial for navigation, as it helps maintain uniformity and predictability in identifying navigational aids. It is pivotal for sailors to recognize that a red buoy indicates that the vessel should keep the buoy on its port side (left side), enhancing situational awareness while navigating coastal and inland waters.

In contrast, other colors like green are used to signify starboard lateral buoys, while blue and yellow do not fit within the traditional lateral buoy color system based on IALA standards. This consistency in color usage allows for safer and more effective maritime navigation.
