Emergency Communication at Sea

When something goes wrong offshore, the difference between a close call and a disaster often comes down to communication. Can you reach rescue services? Can they find you? Having the right emergency communication equipment on board isn't just smart planning. In many cases, it's the law.

Your Emergency Communication Options

VHF Radio (Channel 16)

Your first line of defense. Every boat should have a VHF radio, and it's mandatory on most vessels in Scandinavian waters. But VHF has a limited range of about 20-30 nautical miles. Once you're beyond that, you need satellite.

Satellite Phone

The Iridium 9575 Extreme has a dedicated SOS button that sends your GPS coordinates to GEOS, a 24/7 international rescue coordination center. One press connects you to professional emergency responders who coordinate with local coast guards. Unlike a beacon, you can talk to rescuers and describe your situation.

Personal Locator Beacon (PLB)

A PLB sends a distress signal on the 406 MHz frequency to the COSPAS-SARSAT satellite system. Search and rescue authorities receive your position and dispatch help. PLBs are one-way, meaning you can't communicate back. But they work without subscriptions and batteries last for years.

EPIRB

Similar to a PLB but designed for vessels. EPIRBs (Emergency Position Indicating Radio Beacons) can activate automatically when submerged, sending distress signals even if the crew can't reach them. Required on commercial vessels and recommended for offshore yachts.

What We Recommend

Coastal sailing (under 20 NM from shore): VHF radio + a PLB in your life jacket pocket.

Offshore sailing (20+ NM): VHF radio + Iridium 9575 Extreme. The two-way voice capability makes a huge difference when you need to explain your situation to rescue coordinators.

Bluewater cruising: VHF + Iridium phone + EPIRB + IridiumGO! exec for daily communication and weather. Multiple redundant systems, because you can't call for a tow in the middle of the Atlantic.

Regulatory Requirements in Scandinavia

In Norwegian waters, the Maritime Authority (Sjøfartsdirektoratet) requires specific safety equipment based on your vessel category and operating area. Swedish waters follow the Transport Agency (Transportstyrelsen) regulations. Both align with SOLAS requirements for commercial vessels.

Even if not legally required for your boat, carrying a satellite phone or PLB is strongly recommended by all Scandinavian maritime authorities for anyone sailing beyond coastal VHF coverage.

Frequently Asked Questions

Is a satellite phone or PLB better for emergencies?

Ideally, carry both. A PLB is a last-resort signal with no subscription cost and years of battery. A satellite phone lets you describe your situation, coordinate with rescuers, and contact your emergency contacts. They serve different purposes.

Do I need to register my PLB or EPIRB?

Yes. In both Sweden and Norway, you must register your beacon with the national maritime authority. This ensures rescue services know who to look for when a signal is received.

How fast does rescue arrive after an SOS?

Response times vary by location. In populated coastal areas, rescue helicopters and RNLI equivalents can reach you within 30-60 minutes. In remote offshore areas, it can take several hours. Having accurate position data (GPS) from your satellite device speeds up the process significantly.
