Under the IALA-B Buoyage System, a buoy displaying a red light will be left to what side when entering from seaward?

Under the IALA-B Buoyage System, the navigational rules dictate that a buoy displaying a red light should be left to starboard when entering a port from seaward. This is a key feature of the IALA-B system, which is used in regions such as the Americas, Japan, and the Philippines.

The system is designed to help mariners navigate safely by providing a visual reference for marking channels and hazards in waterways. In this system, buoys are color-coded and marked with lights to indicate the safe side for vessels as they approach port. Specifically, red buoys are used to indicate the right side of the channel when entering from the sea, thus ensuring that they are left to starboard.

This standardization is crucial for maritime safety, as it provides consistency in navigation aids across different regions, allowing mariners to make informed decisions while navigating through potentially hazardous waters. Understanding this system helps ensure that vessels operate safely and efficiently when transitioning from open water into port areas.
