VHF (Very High Frequency) radios are one of the most essential safety and communication tools on the water. Whether you’re a seasoned boater or just getting started, knowing how to properly use a VHF radio is crucial. In this guide, we’ll explore how to use a VHF radio, including its key functions, how to make distress calls, and the price and specifications of different models to consider for your boat.
What Is a VHF Radio?
A VHF radio is a two-way communication device designed for marine environments. It allows boaters to communicate with other vessels, marinas, the Coast Guard, and emergency services. VHF radios use specific channels designated for different types of communication, such as weather updates, general conversations, and emergency alerts.
Unlike cell phones, VHF radios do not rely on signal towers. This makes them a more reliable form of communication in remote areas or offshore where cell reception can be patchy or nonexistent.
Why You Need a VHF Radio
Having a VHF radio onboard is critical for several reasons:
- Safety: If your boat encounters trouble or if you witness another vessel in distress, a VHF radio is the fastest way to reach emergency services like the Coast Guard.
- Weather Updates: You can tune in to NOAA weather channels for real-time marine forecasts, allowing you to avoid dangerous weather.
- Navigation Assistance: Communicate with marinas, bridges, or fellow boaters to get navigation tips or request assistance.
- Legal Requirement: In many regions, having a VHF radio on board is legally required for vessels over a certain size.
Types of VHF Radios
There are two main types of VHF radios you can choose from:
- Fixed-Mount VHF Radios: Installed permanently on the boat with an external antenna, offering greater range and more power.
- Handheld VHF Radios: Portable and can be carried on and off the boat, but generally offer less range compared to fixed models.
How to Use a VHF Radio
Now that you understand the importance of a VHF radio, let’s dive into how to use one.
1. Basic Operation of the VHF Radio
Before using the radio, ensure it is connected to a power source and the antenna is properly installed. Follow these basic steps to operate it:
- Turn On the Radio: Locate the power button or knob and switch it on.
- Adjust Volume and Squelch: Set the volume high enough to hear incoming transmissions clearly. Use the squelch knob to eliminate background noise or static.
- Select the Right Channel: Most VHF radios are pre-programmed with 55 or more channels, each designated for specific purposes:
- Channel 16: International distress and calling frequency (always monitor this channel).
- Channel 9: General calling frequency for non-emergency communication.
- Weather Channels: These channels provide continuous NOAA weather updates.
- Local Marina or Harbor Channels: Used to communicate with harbormasters or other boating services.
2. Making Routine Calls
When you want to contact another boat or marina, follow these steps:
- Select a Channel: Use Channel 9 or another agreed-upon channel (but never Channel 16 unless it’s an emergency).
- Hail the Other Party: Push the microphone button and say the name of the boat or marina you are calling three times, followed by your boat’s name.
- Example: “Marina Harbor, Marina Harbor, Marina Harbor, this is Sea Breeze, over.”
- Wait for a Response: Release the button and wait. If there’s no answer, try again after a few minutes. Avoid interrupting ongoing conversations.
- Switch to a Working Channel: Once you’ve connected, both parties should agree to switch to a working channel for further conversation to free up the hailing channel.
3. How to Make a Distress Call (MAYDAY)
In an emergency, knowing how to make a proper distress call could save lives. Use the following procedure to issue a MAYDAY:
- Switch to Channel 16: This is the emergency frequency that the Coast Guard and other vessels monitor.
- Call Out ‘MAYDAY’ Three Times: Say “MAYDAY, MAYDAY, MAYDAY,” followed by your boat’s name, position, and nature of the emergency.
- Example: “MAYDAY, MAYDAY, MAYDAY, this is Sea Breeze. We are 5 miles south of Clearwater Beach. We have a fire onboard. Over.”
- Wait for a Response: After releasing the button, wait for a reply from the Coast Guard or nearby vessels offering assistance.
- Continue Communicating: Follow any instructions given by rescuers, providing updates on your situation as necessary.
4. DSC (Digital Selective Calling)
Many modern VHF radios come equipped with Digital Selective Calling (DSC), an advanced feature that allows for automated distress signals. To use DSC, you will need to:
- Register for an MMSI Number: This is a unique nine-digit code that identifies your vessel. You can get it from the FCC or through organizations like BoatUS.
- Activate DSC Distress Alerts: If your VHF radio has DSC, pressing the dedicated distress button will send your GPS coordinates and vessel information to nearby boats and the Coast Guard, even if you can’t provide a voice call.

- Keep the Radio on Channel 16: Even if you’re not making a call, always monitor Channel 16 to stay aware of distress calls or important broadcasts.
- Test Your Radio Regularly: Conduct routine radio checks with nearby boats or marinas to ensure your equipment is functioning correctly.
- Avoid Unnecessary Conversations: Keep chatter on working channels to a minimum to leave the airwaves open for essential communication.
