Which color buoy indicates the starboard side of a channel when coming from seaward?

The color red indicates the starboard side of a channel when entering from the sea. In the buoy system used in the United States, which is based on the IALA (International Association of Lighthouse Authorities) system, buoys that are red are marked to signify that boaters should keep these buoys on their right side when navigating into the harbor or channel. This establishes a clear and consistent navigation rule, aiding mariners in safely entering confined waterway areas.

Understanding the significance of buoy colors is essential for safe navigation. Green buoys, for instance, indicate the port side and should be kept to the left when traveling inland, which means they are not correct in this context. Similarly, yellow and white buoys do not specifically indicate channel sides; yellow often serves as a special-purpose buoy, while white buoys are generally used for designated areas such as anchorages or swimming zones. Therefore, recognizing red buoys as markers for the starboard side is crucial for navigational safety.
