What do green buoys typically indicate?

Green buoys are a critical part of the lateral system of navigation aids, which help boaters determine safe navigable waters. Typically, green buoys indicate the port side when entering a harbor or navigable channel. This means that when traveling in a designated waterway, boaters should keep the green buoys on their left (or port) side to navigate safely.

The color coding of these buoys follows a well-understood convention, where green markings signify the left side of the waterway for vessels traveling upstream (towards the area where fresh water flows into the sea, often associated with rivers). Therefore, recognizing the importance of this color and its positioning is crucial for safe navigation.

In contrast, other choices represent different types of navigation aids or markers. Safe water marks, for instance, are typically indicated by red and white vertically striped buoys and signify that you are in safe waters rather than near hazards. Danger areas usually involve red flags or buoys to indicate caution is needed, rather than the straightforward navigation instructions provided by green buoys. Understanding the purpose of each buoy color and its implications in boating is essential for safe operation on the water.
