When navigating toward land from the sea, what do red nun-shaped buoys indicate?

Red nun-shaped buoys indicate the starboard side of the channel when navigating toward land from the sea. This is a critical aspect of the IALA buoyage system, particularly in regions that follow the IALA System A. According to this system, vessels approaching a harbor or navigating inland should keep red buoys to their right (starboard) side, facilitating safe passage through channels and indicating the direction of the navigation rules.

In maritime navigation, these buoys are not just markers but convey specific information regarding channel boundaries and pathway orientation, ensuring that vessels remain within safe navigable waters. By keeping the red nun on your starboard side, you align with the established navigation practices that help prevent grounding and collisions. The distinction and functionality of buoys are essential in maintaining order and safety in busy waterways.
