What does the circle marker indicate?

The circle marker is used to indicate a controlled area. These markers are typically found in locations where boating traffic is managed to ensure safety and compliance with local regulations. A controlled area may have specific rules, such as speed limits, restricted activities, or designated zones for certain types of watercraft. Boaters are expected to observe and adhere to the guidelines provided by these markers to ensure safe navigation and protect the environment or recreational activities taking place in that area.

While other markers serve different purposes, such as exclusion zones that restrict access or hazard areas that alert boaters to dangers, the circle marker specifically designates areas where regulations are controlled and enforced. Understanding these markers is crucial for safe and responsible boating practices.
