What navigational aid is used to mark the starboard side of a channel?

The navigational aid used to mark the starboard side of a channel is a green lighted buoy. This convention is part of the universally recognized IALA (International Association of Lighthouse Authorities) system for buoyage, which dictates the color schemes and meanings for buoys used in maritime navigation.

When approaching a channel from seaward, the starboard side (right side) is indicated by green buoys, which help boaters determine the correct path to follow. These green buoys are typically marked with lights that display a green color, reinforcing their purpose and making them easily identifiable at night or in poor visibility conditions.

Other buoy types serve distinct functions: red lighted buoys mark the port side of a channel, white flashing buoys may indicate safe water or special conditions, and yellow buoys are often used for specific purposes like mooring. Understanding these classifications is essential for safe navigation and ensuring that mariners can follow established maritime protocols.
