Understanding Emergency Communications Equipment

Emergency communications equipment helps alert rescue services, guide search units towards the yacht or survivors, and maintain local communication after normal onboard systems are unavailable.

A complete arrangement may include an EPIRB, personal locator beacons, DSC VHF, satellite distress or messaging devices, SART or AIS-SART equipment, handheld radios and visual signalling equipment.

This free technical guide gives yacht owners and prospective buyers a practical introduction to emergency communications equipment. It explains how different devices provide alerting, identification, location and survivor communication, and why correct registration, mounting, battery condition and crew familiarity are as important as the equipment itself.

Why emergency communications equipment matters

Emergency equipment must remain available after fire, flooding, electrical failure or abandonment has made the yacht’s normal communications systems unusable.

No single device performs every emergency function. An EPIRB may begin the rescue process, but handheld radios, SARTs, personal beacons and visual signals may still be needed to help rescuers locate survivors and coordinate the final stages of recovery.

Equipment may be electrically independent but still fail operationally because it is inaccessible, incorrectly registered, poorly mounted, unfamiliar to the crew or fitted with an expired battery.

A layered arrangement improves resilience by providing several ways to alert, locate and communicate without relying on one device, network or storage position.

What this guide covers

The guide explains:

  • The roles of alerting, identifying, locating and communicating

  • Vessel-mounted and float-free EPIRBs

  • Personal locator beacons

  • DSC VHF distress alerting

  • Satellite distress and messaging devices

  • Radar SART and AIS-SART equipment

  • Handheld VHF radios

  • Pyrotechnic and electronic visual signals

  • Device registration and emergency-contact details

  • GNSS position acquisition and antenna orientation

  • Manual and automatic beacon deployment

  • Hydrostatic-release units, brackets and mounting

  • Batteries, charging, service dates and expiry management

  • Approved self-tests and physical inspections

  • Accidental-alert cancellation procedures

  • Grab-bag storage and abandon-yacht preparation

  • Shared storage, battery, registration and network weaknesses

  • Layered response when one distress path is uncertain

Who is this guide for?

This guide may be particularly useful if you are:

  • Considering the purchase of a motor yacht

  • Preparing a yacht for extended or offshore cruising

  • Reviewing EPIRBs, PLBs, SARTs and handheld radios

  • Trying to understand the purpose of different distress devices

  • Checking registration, battery and service information

  • Planning grab-bag contents and abandonment procedures

  • Investigating failed self-tests or damaged mounting equipment

  • Reviewing whether emergency devices are genuinely independent

  • Looking to improve crew familiarity with emergency activation

Questions the guide will help you answer

After reading the guide, you should be better placed to answer:

  • What equipment is available to alert rescue services?

  • Which devices are associated with the yacht and which travel with individual crew members?

  • Is the EPIRB manually deployed, float-free or both?

  • Is its hydrostatic release correctly installed and within service life?

  • Are EPIRB, PLB and satellite-device registration details current?

  • Do the registered vessel and emergency-contact details remain accurate?

  • Can every device be reached and removed during fire, flooding or abandonment?

  • Do crew members know how to activate and orient each beacon correctly?

  • What is the difference between an EPIRB, PLB, SART and AIS-SART?

  • Are handheld radios waterproof, charged and supplied with suitable spare batteries?

  • Can emergency equipment leave the yacht with the crew?

  • Are devices concentrated in one vulnerable locker or compartment?

  • Have only approved self-test functions been used?

  • Are battery, hydrostatic-release and visual-signal expiry dates being tracked?

  • What alternative alerting and locating methods remain if one device or network fails?
