A marine VHF radio is arguably the single most important piece of safety equipment on your boat. Unlike a cell phone — which loses signal offshore and can’t broadcast to multiple vessels simultaneously — a VHF radio lets you communicate with the Coast Guard, other boats, and marina operators on standardized channels. Channel 16 is the international distress and calling frequency, monitored 24/7 by the Coast Guard and commercial vessels.
In 2026, modern VHF radios include Digital Selective Calling (DSC), which lets you send an automated distress signal with your GPS position to all DSC-equipped receivers in range. This feature has saved lives. If your radio doesn’t have DSC, or if you haven’t registered your MMSI number, this guide will help.
Fixed-Mount vs. Handheld VHF Radios
Fixed-mount radios are permanently wired to your boat’s electrical system and typically use a 15–25 watt output, which gives them significantly greater range than handhelds (which are limited to 6 watts by FCC regulations). Fixed-mount radios connected to a masthead antenna on a sailboat can reach 20–30 miles. For most powerboats, a fixed-mount unit is the primary radio; a handheld serves as backup.
Handheld VHF radios are invaluable as emergency backups, on tenders and dinghies, and for situations where you’re away from the helm. Float-free models even activate automatically if submerged. Keep one charged on board at all times.

Best Fixed-Mount: Standard Horizon GX2400
The Standard Horizon GX2400 is our top pick for fixed-mount radios in 2026. Built-in GPS means your DSC distress call includes your precise location even if your chartplotter is offline. The optional AIS receiver displays nearby vessel traffic directly on the radio’s screen. The large display is readable in sunlight and the audio output is loud and clear in rough conditions.
Best Handheld: Standard Horizon HX890
The HX890 floats face-up, activates its strobe if it sinks, and includes a built-in GPS for position-encoded distress calls. Battery life extends to 15 hours on low power. It’s waterproof to JIS8 (submersible to 1.5 meters for 30 minutes), making it genuinely usable in spray and rain. For emergency kit bags and tenders, this is the handheld to have.
How to Register Your MMSI Number
Your radio’s DSC capability is worthless without a registered MMSI (Maritime Mobile Service Identity) number. Register for free through BoatUS, Sea Tow, or the FCC. Once registered, your MMSI is entered into the radio’s DSC setup. In an emergency, press and hold the distress button for 5 seconds — your radio broadcasts your ID, GPS position, and vessel name to all nearby DSC-capable radios and the Coast Guard.
Pairing your VHF radio with a reliable GPS chartplotter gives you the full picture — real-time positioning and a dedicated communication channel for emergencies.
