Activate an EPIRB (vessel beacon) or PLB (personal beacon) when you and your crew are in immediate danger, unable to make your location known by other means, or when a prompt rescue is required and you cannot safely wait. Use VHF radio (and contact Marine Rescue) for situations that need urgent help but are not necessarily immediately life‑threatening, for coordinating rescue, or when you can give position and situation over radio and stay available to follow instructions.
Practical steps and when to choose which device
- EPIRB/PLB: switch on or release the beacon if you are in grave or imminent danger — for example, when a person is overboard and recovery is unlikely, the boat is sinking or on fire, you are seriously injured and cannot reach help, or you are lost with no reliable way to get home. Beacons alert satellite search-and-rescue systems and start a coordinated response.
- VHF / Marine Rescue: use VHF to call for help when you can communicate your position, nature of the problem and intentions, and remain available on the radio. This covers engine failures, medical problems that can be stabilised, tow requests, or to request local rescue resources that can respond quickly.
- Mobile phones and SMS: useful when you have coverage, but don’t rely on them offshore. If you have mobile coverage and the situation is not immediately life‑threatening you can call for help, but remember coverage is patchy around Tasmania.
Why the distinction matters
- EPIRBs/PLBs alert satellite-based search-and-rescue and usually trigger a broad, organised response; they don’t provide two-way voice communication. Use them when you need rescuers to locate you quickly and you cannot manage the situation by talk and coordination.
- VHF gives two-way voice contact so rescuers can assess, give instructions, arrange tow or local assistance, and coordinate more precisely. It’s the preferred first step when you can communicate effectively and the situation allows.
Important factors that change the decision
- Distance offshore and mobile/VHF coverage: further offshore you are, the more useful a beacon becomes. VHF and mobile coverage can be limited around remote Tasmanian coasts and islands.
- Severity and speed of the emergency: immediate life‑threatening events need an EPIRB/PLB. Gradual equipment failures or medical complaints that can be managed on board usually start with a VHF call.
- Crew ability and onboard capability: if your crew can stabilise an injured person and keep the vessel safe while coordinating assistance by radio, VHF is appropriate; if you cannot, consider the beacon.
Common mistakes to avoid
- Relying solely on a mobile phone when you are offshore — coverage gaps are common around Tasmania.
- Leaving a registered EPIRB or PLB inaccessible (locked in a locker, below deck) — if it’s needed you must reach and activate it quickly.
- Forgetting to register or update beacon ownership details — registration makes it faster for authorities to identify the vessel and respond appropriately.
- Not monitoring VHF when nearshore or in busy areas — having the radio on and tuned to the appropriate channel improves your chance of quick help.
- Accidentally activating a beacon and not cancelling the alert through the proper channels — false alerts consume resources and must be cancelled following the procedures set by rescue authorities.
One realistic next step
Before your next trip around Tasmanian waters: check that any EPIRB/PLB is registered and serviced to the manufacturer’s schedule, carry a waterproof VHF handheld and know how to use it (including how to make a Mayday or Pan‑Pan call), and brief your crew where the beacon and radio are kept and how to operate them.
Note: specific local procedures, channel numbers and the exact steps to cancel an accidental beacon activation are maintained by Australian and Tasmanian rescue authorities; check their published guidance or speak to your local Marine Rescue unit for the most current, location-specific details.
