What is indicated by a yellow buoy?

A yellow buoy is used to indicate special purposes in navigation. This can include various messages or warnings related to specific areas of water that require heightened awareness or caution, such as telling mariners to keep away from certain hazards, or indicating that there may be underwater work or other activities taking place.

Understanding the meaning of the yellow buoy is essential for safe navigation, as it helps mariners to recognize and respond appropriately to these special situations that may not be covered by more standard navigational aids. It is an important part of a mariner's toolkit to interpret buoys and their meanings correctly to ensure safe passage.
