Which buoyage system is characterized by "Red Right Returning"?

The buoyage system characterized by "Red Right Returning" is IALA B. This phrase is a mnemonic that helps navigators remember how to recognize the position of navigational buoys in relation to the vessel's direction of travel. When a vessel is returning from sea to port, navigators should keep red buoys on their right side; this indicates that they are on the correct course within the navigable channel.

IALA B is primarily used in North America and parts of South America, as well as in many parts of Asia. It contrasts with the IALA A system, which is used in Europe and most of Asia, where the color scheme and buoy arrangement differ.

Understanding the "Red Right Returning" mnemonic is crucial for ensuring safe navigation and adherence to maritime rules, especially in areas with dense traffic and potential hazards. The other options do not pertain specifically to the buoyage system's color-coding or arrangement used for maritime navigation.
