The short answer is, yes, you most definitely need a VHF radio or 2-way radio particularly if you boat any significant distance from the shore. But, why? If you get into trouble you can simply call the authorities on your cell phone, right? Well…maybe and maybe is not the answer you want in an emergency. The following are the reasons you need a VHF radio on your boat in addition to your cell phone.
VHF Radios Can Operate Without a Network
Imagine that you find yourself in an emergency situation and you are offshore and away from cell towers. Or maybe you are not that far offshore, but the day is very overcast and your phone is having difficulty obtaining reception. You need to contact the authorities or other support and you look down at your phone and see no or maybe only one of those coveted bars. With VHF radios you never have to worry about losing service. While cell phones rely on cell reception, data, and wifi, two-way radios are a self-contained communications network. This means that if for whatever reason cell phones aren’t working, your two-way radio is there at the ready.
They Can be Waterproof and Sandproof
Certain two-way radios are built to withstand very harsh environmental conditions. Rain, sand, extreme cold do nothing to stand in the way of these rugged radios as many two-way radio models are waterproof and sand-proof. Some can be submerged in water for up to 30 minutes, in a depth of three feet, and still be functional.
They Can Greatly Improve Efficiency & Responsiveness
Multiple people can be dispatched at one time reducing the need to call people individually. In addition, everyone involved in an emergency situation can communicate instantly assuring help is on the way as quickly as possible and all involved can stay in touch in the meantime.
They Can Communicate Across Great Distances
With the right technology in place, a two-way radio’s coverage can be extended across a very wide distance - 30+ miles. Obstacles in a radio’s line of sight will block or diminish its signal, but more powerful antennas can substantially extend this distance.
They Can be Reached by Telephone
Many two-way radios have what’s called a telephony feature, which allows for communication between the radio and a landline, or cell phone. This is possible because radio base repeater stations can be connected to telephone networks. Telephony functions are very helpful if there might be a need to communicate with people who don't have a two-way radio. This said, emergency and rescue organizations are very used to communicating with two-way radios.
Long Battery Life – Backup Communications
Fixed VHF radios are powered by the boat’s electrical system. However, handheld 2-way radios generally have longer battery lives than your cell phone and serve as great backup communication devices.
VHF Radios Have A Lot of Uses Beyond Emergency Communications
Radio ahead for a berth at a marina or maybe you want to chat with a passing boat for advice on entering a new channel. Do keep in mind, however, marine VHF radios, whether fixed or handheld, may not be used on land - it’s the law. Once a VHF radio goes ashore, it cannot be used for marine band transmission without a Coast Station license. While your marine VHF radio cannot be used onshore, many boaters find 2-way radios not using a marine band transmission – think walkie talkie from your childhood – handy for communicating fairly short distances with friends and family while onshore.
