What is OLAS?

OLAS stands for Overboard Location Alert System. It has been developed to provide a scalable wireless safety system for motor and sailing vessels up to 80ft in length. OLAS creates virtual tethers to crew, family, pets and objects ensuring that if they fall overboard an alarm is triggered. OLAS is split into 2 product functions; OLAS transmitters and OLAS receivers.

OLAS Transmitters

The OLAS Tag and the OLAS Float-ON are considered OLAS transmitters. They emit a Bluetooth signal, which is monitored by any OLAS receivers, creating a wireless tether.

The transmitters are portable devices to be carried, worn or attached to crew, family and pets.

OLAS Receivers

The OLAS receivers track the OLAS transmitters. OLAS receivers are:


Installed wireless kill switch and overboard alarm


Portable overboard alarm

OLAS mobile application

Portable overboard alarm and rescue aid


A repeater to increase the range of the Guardian and Core up to 80ft

How does it work?

OLAS transmitters are synced up with the receivers whilst in dock. The system then operates in the background, continuously checking to ensure all crew, family and pets are still within range. When the virtual tether is broken between a receiver and a transmitter, the receiver triggers an alarm, emergency light and OLAS mobile application.

Instant alert to an overboard incident enables rapid recovery to be actioned.

The OLAS Mobile Application

The OLAS mobile application allows the OLAS transmitters to be used as a MOB/proximity alarm creating a portable system that can be taken from vessel to vessel without costly installation. When an OLAS transmitter goes out of range an alarm is set off and overboard screens are activated.

When the OLAS mobile application is connected to the Guardian or Core it allows greater control over the OLAS transmitters that are being tracked, whilst also acting as an extra alarm and rescue aid.

What is OLAS?

The OLAS app has 4 key rescue features, automatically activated when the MOB alarm sounds:

  1. Records and displays MOB Alert GPS position (no cell phone signal required)
  2. Displays MOB mayday call with custom vessel information and MOB Alert GPS position
  3. Clear arrow directing back to the MOB Alert GPS position
  4. Solo mode – automatic SMS to custom number with MOB Alert GPS position
