When returning to port from seaward you see a red buoy?

When returning to port from seaward, a red buoy indicates that you should keep it on your starboard (right) side. This is part of the IALA maritime buoyage system, which helps vessels navigate safely. If you see a red buoy, it typically means you are approaching a channel or harbor entrance, so you should proceed with caution and be aware of other navigational markers.
