What is the significance of a red buoy?

A red buoy primarily denotes the starboard side when returning from sea, according to the lateral system of buoyage used in navigation. This means that if a vessel is approaching a harbor or dock from the open water, red buoys should be on the right side of the vessel. This system allows mariners to easily identify safe navigation routes and helps maintain proper traffic patterns in waterway navigation.

The role of red buoys in maritime navigation is rooted in the International Association of Lighthouse Authorities (IALA) buoyage system, which defines red as a color indicating the starboard side, while green indicates the port side. This color-coding provides the essential information necessary for mariners to navigate safely and effectively. Understanding this system is crucial for vessel operators, especially in busy or congested waterways where safety is a priority.
