VHF Radios: Essential Safety and Communication for Sailors

A VHF radio is one of the most important pieces of equipment on any sailing yacht, motorboat, or dinghy that ventures beyond the marina. While mobile phones have their place, they are no substitute for the reliability and functionality of a VHF radio when it comes to safety at sea and effective communication on the water. For many sailors, having at least one handheld VHF onboard is as critical as carrying lifejackets.

In this article, we’ll look at why VHF radios remain a cornerstone of seamanship, what features to prioritise when buying a handheld unit, and how to distinguish between basic and advanced models.

Why Every Boat Needs a VHF Radio

Unlike mobile networks, VHF operates on a dedicated marine frequency with line-of-sight communication. This ensures dependable coverage for ship-to-ship, ship-to-shore, and – crucially – distress calling. Coastguards, harbours, and other vessels constantly monitor VHF channels, making it the fastest way to summon help or share navigational updates.

A handheld VHF is particularly valuable because it is portable, waterproof, and independent from the boat’s main systems. Should you need to abandon ship, a handheld radio can go with you into the liferaft and remain your lifeline to rescue services.

Key Functions of VHF Radios

Modern VHF radios offer a range of features beyond simple two-way communication:

• DSC (Digital Selective Calling): Allows direct distress signalling and private calls to other DSC-equipped radios.
• Weather channels and alerts: Many models provide access to forecasts and automated safety warnings.
• Dual or Tri-Watch: Lets you monitor multiple channels simultaneously – usually Channel 16 (distress/calling) plus another working channel.
• GPS integration: Some handheld VHFs include built-in GPS, automatically transmitting your position during a DSC distress call.
• Float and flash technology: If dropped overboard, the radio floats and activates a strobe light for quick recovery.

Not all radios include these capabilities, so the choice depends on your sailing style, budget, and level of offshore activity.

What to Look for in a Handheld VHF Radio

When selecting a handheld VHF, there are several technical considerations that separate a good radio from a less reliable one:

Battery Life and Power Output

Most handheld VHFs offer 5–6W of transmit power, with selectable low-power modes to conserve energy. A long-lasting lithium-ion battery, ideally with USB-C charging options, makes life easier both onboard and ashore.

Waterproofing and Durability

Look for an IPX7 or IPX8 waterproof rating, meaning the unit can withstand immersion. Shock resistance and robust casing are equally important for use in harsh marine environments.

Ergonomics and Usability

Large, backlit buttons and a clear display are vital when operating in poor light or wearing gloves. Some models feature voice annunciation or customisable keys for quick access to favourite channels.

Size and Weight

Compact, lightweight radios are easier to carry clipped to a lifejacket or stowed in a grab bag, but they must still feel solid in the hand.

Advanced Features

Integrated GPS, DSC calling, and float/flash recovery systems are worthwhile upgrades if you sail offshore or participate in racing where safety regulations demand higher specification gear.

Handheld vs Fixed VHF Radios

A fixed VHF set, usually installed at the nav station with an external antenna, provides greater range due to higher transmit power and better aerial height. However, it cannot substitute for a handheld unit in an emergency. Many skippers carry both: the fixed VHF for routine communication and a handheld as backup and for use on deck, in the dinghy, or in the event of power failure.

Choosing a Trusted Brand

The VHF radio market includes a wide range of brands and quality levels. While budget models may look attractive, reliability and build quality are paramount when your safety depends on them. ICOM is one of the world’s most respected marine electronics manufacturers, renowned for robust radios with excellent performance and long service life. That is why we have started our handheld VHF category with ICOM products and will continue to expand our range over time.

Conclusion on VHF Radios: A Small Investment in Safety

A VHF radio is more than just a communication tool – it is a lifeline. Whether you are day sailing along the coast or planning longer offshore passages, carrying a reliable handheld unit provides peace of mind for you and your crew.
