If you see a quick flashing green light ahead of you in the channel, where should you leave the buoy?

A quick flashing green light indicates a green buoy, which typically marks the right side of a channel when you are proceeding upstream or entering a harbor. According to the IALA (International Association of Lighthouse Authorities) buoyage system, the convention is that when following the channel, mariners should keep the green buoys on their starboard side.

Therefore, when you see a quick flashing green light ahead of you, you should leave the buoy to your starboard, as this is the established navigational practice. Maintaining this practice ensures safe passage and adherence to navigational rules, helping to prevent collisions and groundings. Understanding the buoyage system helps mariners navigate safely in confined waters where clear channel markings are essential for safe navigation.
