OLAS Core is a small, portable, wireless Man Overboard Alarm system for boats up to 50ft long and up to 15 crew. It instantly triggers a loud, 85 decibel emergency alert, within four seconds if there is a man overboard incident.

Using the latest wireless technology, OLAS Core creates a virtual lifeline by connecting each crew member wearing an OLAS transmitter, such as the OLAS tag wrist band or the small OLAS Float-On personal light, to the boat. In the event of a MOB situation its visual and audible alerts mean the crew can respond instantly.

OLAS Core is a small, portable ‘hub’ which can be placed anywhere on the boat and transmits a continuous wireless signal tethering the crew to the boat.

It also connects with the OLAS mobile App, which includes easy-to-use screens to connect, monitor and personally label the connected tags. Whilst the App is used for system management, the powerful connection signal to the Core unit is entirely independent of the varied qualities of different personal mobile devices and whether they are charged up.

Tom Harrop, Product Manager at Exposure Lights explains, “Losing a crew member overboard is every sailor’s worst nightmare. The larger the boat, the more difficult it can be to know instantly that a MOB incident has occurred, especially if the crew are working up forward in the dark. OLAS Core gives skippers of larger boats with a large crew, complete confidence that in the event of a MOB incident, the entire crew are alerted immediately, and can take immediate recovery actions.”

OLAS Core’s range can be increased for larger vessels up to 80’ using the OLAS Extender, which also helps to repeat the connection around vessels with more challenging superstructures such as steel, aluminium and carbon.
