A green buoy should be passed on the starboard (right) side when traveling upstream or towards the buoy's marking. This is in accordance with the IALA (International Association of Lighthouse Authorities) maritime buoyage system, which indicates that green buoys mark the port side of a channel when coming from seaward. Always ensure to maintain a safe distance from the buoy to avoid grounding. Keep a lookout for other vessels and navigational hazards while passing.

A green buoy should be passed on the starboard (right) side when navigating. This is in accordance with the "buoyage system," which indicates that vessels should keep green buoys to their right when proceeding upstream or toward the harbor. In general, this helps ensure safe passage and maintain proper navigation.
The green buoy should be on the left (port) side of the boat as you are entering port.
In Region A it is a starboard hand buoy, in Region B it is a port hand buoy. These are lateral marks and in some areas the shape of the buoy cannot be relied upon.
Always kept on the port side
When returning from sea, a green navigational buoy should be passed on the starboard (right) side of the vessel. This follows the IALA (International Association of Lighthouse Authorities) buoyage system, which indicates that green buoys mark the port side when approaching from the sea. Always ensure to navigate safely and be aware of your surroundings when passing navigational markers.
They should be passed on your starboard side.
Keep the buoy on your port (left) side.
