What is the purpose of the "sound signals" in navigation?

The purpose of sound signals in navigation is primarily to communicate intentions or warn other vessels of your presence, especially in conditions where visibility is limited, such as fog, heavy rain, or at night. Sound signals enhance safety on the water by ensuring that other boaters are aware of one another’s locations and movements, which is crucial to preventing collisions and maintaining safe navigation practices.

For instance, a vessel may use specific sound signals to indicate actions such as turning, stopping, or making an approach, which are essential for conveying intentions without relying solely on visual signals that may not be seen in poor visibility conditions. This is particularly important in crowded waterways where multiple vessels may be operating in close quarters. Using sound signals effectively helps all operators navigate safely and responsibly.
