Which type of buoy is ALWAYS GREEN and has ODD numbers?

The correct answer identifies cylindrical-shaped can buoys as the type that is always green and has odd numbers. In the maritime navigation system, buoy color and shape are designed to convey specific information to mariners.

Cylindrical-shaped can buoys are part of the IALA (International Association of Lighthouse Authorities) A system, which is commonly used in the United States. According to this system, can buoys are green and marked with odd numbers, guiding boaters by indicating the port side of a channel when approaching from seaward. This helps maintain safe navigation, as the preferred channel markers are standardized to reduce confusion among mariners.

Recognizing the specific characteristics of buoys is essential for safe boating practices, as it allows operators to navigate effectively and stay within marked channels, ultimately preventing accidents.
