What type of area does a circle indicate?

A circle typically indicates controlled areas on navigational charts and signs related to boating. Controlled areas are zones where certain rules and regulations apply based on local regulations or safety precautions. These might include areas where there are speed limits, restrictions on certain types of activities, or guidelines to follow due to environmental concerns or safety considerations.

In contrast, exclusion areas indicate places where entry is prohibited; danger areas are marked to alert boaters of possible hazards; and information zones are used to provide guidance or additional information to the public. Understanding the significance of a controlled area is crucial for safe and compliant boating.
