A VHF marine radio is a vital piece of safety equipment while out at sea for making emergency calls. It is also used to communicate with coast stations, port/harbour authorities and with other vessels.
It is important to remember that you will need to obtain a Licence and the appropriate qualification to operate a VHF marine radio.
