Why choose OLAS Core?
OLAS Core is designed for skippers who want a reliable, always-on safety layer that doesn’t depend on a phone or manual intervention. By continuously monitoring every connected crew member, it provides immediate awareness of a man overboard situation - something that can easily be missed on larger or more active vessels.
The combination of instant onboard alarms and mobile app support helps crews react faster, maintain situational awareness, and return to the exact incident location more efficiently. For vessels operating with multiple crew, changing conditions, or reduced visibility, it significantly improves response time when it matters most.
Key Features
OLAS Core acts as a dedicated onboard safety hub, offering:
- Instant man overboard alarm activation (typically within seconds)
- Connects and monitors up to 25 OLAS transmitters
- Loud 85dB audible alarm with high-visibility LED warning light
- Portable, USB-powered design – no hard wiring required
- Integration with OLAS mobile app for GPS tracking and recovery guidance
- Expandable coverage for larger vessels using OLAS Extender
- Assignable tags for crew, pets, or equipment monitoring
It is designed to provide a dedicated safety layer independent of mobile devices, ensuring alerts are always delivered onboard when needed most.
