What does "Red Right Returning" refer to in the IALA B buoyage system?

"Red Right Returning" specifically refers to the buoyage system used in the IALA B, which indicates that when navigating into a harbor or up a channel, the mariner should keep the red buoys on their right side. This is essential for ensuring a safe passage as the red buoys are meant to mark the navigational channel, guiding vessels safely towards the harbor. The phrase serves as a mnemonic device to help mariners remember the correct side to pass these buoys when returning from the sea.

The focus of this concept is primarily on the color and position of the buoys relative to the direction of travel, which aids in preventing groundings or collisions in unfamiliar waters. It's crucial for mariners to recognize this rule while navigating to ensure they are properly aligned with safe navigational paths.
