Which statement correctly describes a Can buoy?

• A. Red, even numbers
• B. Green, odd numbers
• C. Green, even numbers
• D. Red, odd numbers

Answer: (B)

Can buoys are the green, cylindrical marks in the buoyage system. They mark the left side of the channel when approaching from the open sea. In this system, the numbers on can buoys are odd, while red nun buoys (the conical ones) carry the even numbers. So describing a Can buoy as green with odd numbers fits exactly with how these marks are intended to be read and navigated by paddlers. The other color/number combinations don’t align with how can and nun marks are distinguished.
