When returning to home port from seaward and you see a red bout how should you respond?

When returning to home port from seaward and you see a red buoy, it typically indicates a "port" side marker, which means you should keep the buoy on your port (left) side as you navigate towards the harbor. This is part of the IALA (International Association of Lighthouse Authorities) system of navigation aids. Ensure you adjust your course accordingly to safely pass the buoy without any risk of collision. Always be aware of other vessels and any navigational hazards in the area.
