If you see a white buoy with orange horizontal stripes and a cross inside a diamond, what does it indicate?

A white buoy with orange horizontal stripes and a cross inside a diamond signifies a boat exclusion area. This marking is crucial for ensuring safety in specific zones where boating is prohibited, often to protect wildlife, swimming areas, or to avoid hazards that could be dangerous for boaters. The orange cross specifically indicates that no vessels should enter the area, helping to maintain order and safety on the water.

While other buoy markings correspond to different activities, such as water skiing or designated fishing areas, the distinct combination of horizontal stripes and the cross is specifically intended to denote exclusion, making it essential for boaters to recognize and adhere to these markers for their safety and environmental protection.
