A SB 5 yellow buoy, often referred to as a special buoy, indicates a specific navigational or regulatory purpose, such as marking a channel, hazard, or restricted area. The yellow color signifies that it is not a standard navigational aid but serves a unique function, which can vary by region. These buoys may also indicate locations of underwater pipelines or other hazards. Always refer to local navigation charts for precise meanings and regulations associated with specific buoys.
