Which buoy type is cylindrical, green, and often carries an odd number?

• A. Can Buoy
• B. Nun Buoy
• C. Spar Buoy
• D. Lighted Buoy

Answer: (A)

In buoyage, color and shape tell you what side of a channel you’re on. Green and cylindrical identifies a Can buoy, which marks the port (left) side of the channel in many systems. These buoys are designed to be easily recognized by their tall, drum-like shape, and they often carry numbers to help you track positions along the route. The other common types don’t share this exact combination: a Nun buoy is red and conical, a Spar buoy is a tall post-like shape, and a Lighted buoy can be any shape but is defined by having a light. So the cylindrical green buoy described fits the Can buoy.
