What type of vessel must have a horn or whistle onboard?

Motorized vessels over 12 feet in length must have a horn or whistle onboard as part of safety regulations. This requirement is designed to ensure that these vessels can signal their presence and communicate with other vessels, especially in situations where visibility is impaired or during busy waterways.

Having a sound signaling device is crucial for motorized vessels because they are typically larger and may operate at higher speeds compared to smaller vessels. This facilitates safer interactions with other watercraft, aiding in navigation and preventing collisions. The regulation helps enhance safety by making it easier for other boaters to be aware of a motorized boat’s location and intentions.

In contrast, non-motorized vessels and smaller sailboats may have different signaling requirements based on their size and operational capabilities, reflecting the built-in safety features associated with their design and usage.
