What are can buoys marked with?

Can buoys are crucial for navigation on waterways and indicate safe passage for boaters. These buoys are specifically marked with green markings and often use odd numbers to help boaters identify their position along the waterway.

This system of using green, odd-numbered buoys helps in distinguishing them from other navigational markers, such as red buoys, which typically denote the right side of the channel when entering from open water. The green can buoys guide boats to safer routes that avoid hazards, maintaining a consistent pattern that is easier for all boaters to understand and follow.

The use of odd numbers on can buoys helps to provide a clear wayfinding system, as these numbers increase in ascending order when traveling upstream. This standardized system is vital for safe navigation, as it allows all waterway users to understand their surroundings and avoid potential accidents or grounding in shallower areas.
