How are can buoys visually identified?

Buoys are visually identified primarily by their color and markings, which are standardized to convey specific information to boaters. In this context, green buoys are used to mark the navigational path in a waterway and are typically associated with even-numbered markings. This system is part of the lateral buoyage system that helps indicate safe passage along channels.

Green buoys suggest that boats should keep them to port (the left side when heading upstream), and they are aligned with odd numbers to indicate their sequence along the waterway. This color and numbering system is crucial for safe navigation, as it helps boaters understand where they are and how they should proceed to avoid hazards.

In contrast, other options involve different colors and patterns that do not adhere to this specific navigational guidance. For instance, red buoys indicate the opposite side of the channel, often marked with even numbers, while blue and white options lack relevance in traditional lateral markers used in navigation. Understanding these visual cues ensures that boaters can safely navigate through waterways, avoiding potential dangers.
