What signaling device must all boats carry?

The requirement for all boats to carry sound signaling devices is grounded in the need for safety and communication on the water. Sound signaling devices, such as whistles, horns, or other audible signals, are essential for alerting other boaters to your presence, especially in situations where visibility might be limited, such as fog or heavy rain. These devices help prevent collisions by allowing one vessel to signal its location or intention to another.

While visual signaling devices, such as flares or flags, are also important for safety, they are not mandated for every type of boating situation. Electronic signaling devices, like marine radios or emergency distress beacons, enhance communication but are not universally required on all boats. Hence, the inclusion of sound signaling devices in the mandatory safety equipment ensures that all boats can communicate effectively and maintain safety standards on the water.
