How to Use a Marine VHF Radio

A marine VHF radio is more than a communication tool—it is a lifeline for boaters, ensuring safety and connectivity on the water. Whether you need to coordinate with nearby vessels, contact the Coast Guard, or request assistance in an emergency, a VHF radio plays a pivotal role. America's Boating Club | United States Power Squadrons provides education on boating safety, including comprehensive training on how to use a marine VHF radio effectively.

Whether you’re a new boater learning the ropes or an experienced mariner brushing up on skills, understanding the correct operation and etiquette of a marine VHF radio is essential. This guide will walk you through the basics of operation, proper channel usage, and the benefits of choosing the right equipment, including advanced models like marine VHF radio with AIS and marine VHF radio with GPS. We’ll emphasize how courses and resources from America's Boating Club | United States Power Squadrons can take your boating expertise to the next level.

How to Operate a VHF Marine Radio?

Operating a marine VHF radio might seem straightforward, but following proper procedures ensures effective communication and safety. Turning on the radio the radio is automatically tuned  to Channel 16, the universal hailing and emergency channel and set on the highest power setting the radio has. Adjust the volume and squelch settings to minimize background noise while maintaining clear reception. 

When making a call, clearly state the name of the vessel you are hailing, and your vessel name. For example: “Blue Horizon, this is Sea Star on Channel 16”. Repeat this three times. When Blue Horizon answers your call, advise your intention to switch to a working channel. For example: “Blue Horizon, this is Sea Star on Channel 16. Let’s move to Channel 68.” Wait for acknowledgement before proceeding to the designated channel.

For optimal safety, keep a handheld marine VHF radio as a backup. Handheld units are particularly valuable for small boats or as a secondary communication device in case of power loss or equipment failure. Following proper radio protocols ensures your messages are clear and concise, reducing the risk of confusion in critical situations.

What Channel Should I Keep My Marine Radio On?

Understanding the functions of different marine VHF radio channels is critical for smooth communication:

• Channel 16: The primary hailing and emergency channel, monitored continuously by the United States Coast Guard and other vessels. All boaters should tune in to this channel when not actively communicating elsewhere.
• Channel 9: A recreational hailing channel often used to reduce traffic on Channel 16. The United States Coast Guard does not actively monitor this channel
• Working Channels (e.g., 68, 69, 71, 72): Designated for ship-to-ship or ship-to-shore communication once initial contact is made.

Monitoring the appropriate channels ensures you’re aware of important announcements and nearby vessels’ activities. Misusing hailing channels for casual conversation can block access for others in emergencies, so always move to a working channel promptly.

How Do I Call Another Boat on VHF?

Hailing another vessel requires following proper maritime protocols to ensure clarity and professionalism. Here’s how to initiate contact:

1. Switch to Channel 16 or Channel 9 to hail the vessel.
2. Announce the name of the vessel you’re calling, followed by your own vessel’s name, repeated three times. 
3. Wait for the other vessel to respond and state your desired communications channel.
4. Wait for the other vessel to confirm the working channel before switching.
5. Once connected on the working channel, keep communication brief and return to Channel 16 when finished.

For emergencies, follow the Mayday protocol, which includes stating “Mayday” three times, followed by your vessel name, position, and nature of distress. Taking a course through America's Boating Club | United States Power Squadrons will help you master these procedures, ensuring you’re prepared for any scenario.

Choosing the Right Marine VHF Radio

Selecting the right radio for your vessel depends on your boating needs. There are two main types to consider:

• Handheld Marine VHF Radio: Portable and compact, these radios are ideal for smaller boats or as a backup. They’re easy to use and convenient for short-range communication.
• Fixed Mount Marine VHF Radio: Designed for extended range and equipped with advanced features such as DSC (Digital Selective Calling),AIS (Automatic Identification System) and GPS. Radios with AIS can identify nearby vessels and avoid potential collisions, while GPS integration provides precise location data for navigation and emergencies.

Investing in a marine VHF radio with GPS or AIS can significantly enhance your boating safety and convenience. For optimal results, ensure the radio is properly installed and maintained, with regular checks to confirm functionality.

Advanced Features to Consider

Modern VHF radios offer features that can elevate your boating experience:

• Digital Selective Calling (DSC): Allows for automated distress signals with location data, ensuring faster emergency response.
• NOAA Weather Alerts: Keeps you informed of changing conditions on the water.
• High-Quality Audio: Reduces static and ensures clear communication in noisy environments.

Learning to operate these advanced features is part of the training provided by America's Boating Club | United States Power Squadrons.
