What do circles indicate in a controlled area on the water?

Circles in a controlled area on the water indicate that vessels must maintain a no-wake speed. This means that boat operators must navigate their vessels at a speed that does not create a wake, ensuring safety and minimizing disturbances in that area. No-wake zones are often established near docks, swimming areas, or other locations where increased caution is necessary for the protection of people and property.

Understanding the implications of no-wake zones is crucial for safe boating practices. These areas are typically designated to prevent boat wakes from causing damage to nearby structures, or to protect individuals who may be swimming or engaged in other water activities. Adhering to the no-wake speed requirement ensures that both the vessel operators and those in the water can safely coexist in these controlled spaces.
