Special-Purpose Buoys—Information, Hazard, Control, and Keep-Out
These special-purpose buoys have orange symbols on white pillars, cans, or spars. They are used to:
- Give directions and information.
- Warn of hazards and obstructions.
- Mark controlled areas.
- Mark keep-out (closed) areas.
Squares provide information such as places to find food, supplies, and repairs. They also give directions, distances, and other non-regulatory information.
Diamonds warn of hazards such as rocks, shoals, or turbulent waters. Always proceed with caution and keep a safe distance. Never assume that every hazard will be marked by a buoy.
Circles indicate a restricted boating area such as no wake, idle speed, speed limit, or wash restrictions. You must obey the restriction inside the circle.
Crossed diamonds indicate areas where pleasure craft are prohibited such as dams and spillways.
