Step-by-step explanation:
A boat less than 12 meters (39.4 feet) in length must have a VHF radio or cell phone, a sound signaling device, and a seat for every passenger aboard.
A VHF radio or cell phone is necessary for communication and emergency purposes. A sound signaling device, such as a horn or whistle, is required to alert other boats in case of danger. And a seat for every passenger is essential for their safety and comfort while onboard.
