An EPIRB and a personal locator beacon answer related but different questions: how will the yacht carry a distress beacon, and what will a person have available if separated from it? For extended cruising, useful selection starts with those situations rather than a verdict that one device replaces the other.
Think through life aboard and away from the boat. A beacon accessible on the yacht may not be accessible to someone on a tender trip. A personally carried unit may travel ashore with one crew member while others remain aboard. Mapping those ordinary movements reveals where each option could help.
Plan for separation before choosing equipment
Consider a vessel emergency, a tender excursion and a person separated from the yacht. For each, ask where the beacon would be, who could reach it, and who could operate it. Do not assume that a unit stored in a drawer will be available simply because it is aboard.
Tender Launch and Recovery: Evaluating the Complete Routine for Cruising Couples is a useful companion to this review: include emergency equipment in the routine you assess, alongside handling and access.
Beacons are part of a broader communications plan. Our Remote Cruising Navigation and Communications: Building a Layered Backup Plan considers complementary ways to communicate; a distress beacon should be understood on its own terms rather than treated as a substitute for every other tool.
Compare the exact EPIRB and PLB
NOAA emergency beacon guidance distinguishes maritime EPIRBs from personally carried, manually activated PLBs. The category helps define the job, but the actual model, bracket and instructions determine how the unit is carried and used.
| Selection question | Vessel EPIRB | Personal locator beacon |
|---|---|---|
| Where will it be available? | Review its approved bracket or carriage location aboard | Review how it will be carried by the person who needs it |
| How is it released and activated? | Distinguish a float-free automatic arrangement from manual release; check the exact model | Plan around manual activation and the exact instructions |
| What happens in water? | Verify the model’s flotation and operating requirements | Verify whether flotation support is needed and how the unit must be held or positioned |
| What needs ongoing attention? | Battery, bracket/release equipment where fitted, self-test and registration | Battery, carrying arrangement, self-test and registration |
Vessel-mounted choices
A float-free EPIRB arrangement and a manually released EPIRB are different choices. Ask the supplier how the proposed unit and bracket work together, and have the installation assessed for the actual yacht. An unobstructed release path matters for an arrangement intended to float free.
Manual access matters too. Review whether crew members can reach the installed unit and understand its controls. Manufacturer instructions should settle mounting, release and activation details; a general comparison cannot specify them for an unknown model.
Personal carriage choices
A PLB’s portability is useful only if the intended person has it available. Check how the proposed unit fits the person’s clothing or safety equipment, whether it floats, and how its antenna and controls must be used. Manual activation deserves particular attention: carrying a PLB does not mean an accidental fall will automatically send an alert.
This comparison can support complementary carriage, but it is not a universal equipment mandate. Choose the package around the yacht, route, crew and applicable requirements with the supplier.
Register for the beacon’s coding and current use
Beacon identity is separate from the yacht’s MMSI. Check the beacon label and national registration instructions for its unique identifying code and country coding.
NOAA registration requirements apply to its U.S. registry. Keep the owner, emergency contacts, and relevant equipment or vessel details current. The NOAA beacon registration FAQ asks owners to renew registration every two years; also update changed information when needed.
The NOAA registration update announced on March 4, 2026 added Iridium information for EPIRB/SSAS registrations and additional vessel, aircraft and home-port information for PLBs. It added fields rather than changing the two-year renewal interval. Use the available fields to make the registration reflect how you actually use the beacon.
For Canadian-coded equipment, the Canadian Beacon Registry accepts beacons programmed with Canada’s country code. Its current guidance identifies vessel details for EPIRBs, intended use for PLBs, equipment identifiers and emergency contacts as relevant records. If ownership or country registration changes, ask the registry and manufacturer about the proper transfer or reprogramming route; do not improvise a device change.
Check readiness without sending a distress alert
Registration readiness and physical readiness are separate checks. A correct registration cannot repair a depleted battery, and a functioning beacon can still carry outdated contact details.
Before departure, review:
- The installed model’s battery and replacement markings.
- The manufacturer’s self-test method and any limits on test frequency.
- Bracket and release-component condition and dates where applicable.
- Ownership, country coding, registry details and emergency contacts.
- The crew’s ability to locate the beacon and understand its instructions.
Use the prescribed self-test rather than activating the distress function to see whether the unit works. Keep the manual available and arrange manufacturer-approved service where required.
