When returning from sea, a red navigational buoy should be passed in what manner?

When returning from sea, the correct procedure is to always keep a red navigational buoy on the starboard side. This practice is in accordance with the "handing rules" of buoyage systems, particularly the IALA (International Association of Lighthouse Authorities) system used in the United States.

Red buoys, also known as channel markers, indicate the right side of the channel when approaching from the sea. By keeping these buoys on your starboard (right) side, you ensure that you are navigating safely within the designated waterway. This rule helps prevent navigational hazards and promotes standard practices among all boaters, thereby reducing the risk of collisions and grounding.

This specific practice is fundamental for safe boating and aids in consistent maritime navigation, allowing boaters to communicate effectively regarding their positions and intentions on the water.
