The OLAS system uses Alert and Find technology to create a portable crew tracking and overboard location alert system.

In an MOB situation OLAS will sound an alarm and record the latitude and longitude of the incident using the phone or tablets GPS.

In the event that the skipper or a crew member has gone overboard OLAS helps direct the remaining crew on a successful MOB recovery and communication with emergency services

 

 

 

OLAS USES

 

  1. Ensure all crew members are present
  2. Significantly increase the chance of self-rescue in a Man Overboard emergency
  3. Clearly and concisely transfer relevant information to the  coast guard
  4. Monitor live navigation data whilst cruising or racing

 

OLAS Tags pair with your device to create a virtual tether between your phone/tablet and crew members, children, pets or objects, such as a lifebuoy.

When the virtual tether is ‘broken’ OLAS will:

  1. Emit an audible alarm and light signal
  2. Record the time and GPS location where the incident occurred, and your current GPS location  
  3. Clearly illustrate the direction and course to return to the alert GPS location

 

 

Attach OLAS Tag to individual or life-saving device

Your OLAS Tags can be either worn , or attached to an object, such as a lifebuoy, upgrading pre-existing MOB devices into ‘smart’ connectable devices.

MOB Alert Screens

 

The compass gives a simple clear visual aid to steer to the direction where the alert occurred. An arrow points to the logged coordinates and tells you the compass bearing and distance to return to the incident co-ordinates.

You are also given the direction that the phone is pointing, to enable a bearing to be taken to estimate tidal and wind effects, if needed.

OLAS will also alert you when you within a 20m radius of the original alert position.  From that location it will be far easier to establish where the MOB has drifted to.

The Alert Latitude and Longitude are stored along with the time of the incident and the vessels current Latitude and Longitude.  

This is displayed clearly on the screen allowing the user to easily inform the rescue services of the important information.

 

OLAS APP walks you through making a DSC Distress alert and MAYDAY call.  In a stressful situation it’s easy for even experienced sailors to ‘go blank’.  Every second is vital.

Pre-set your OLAS APP with your vessel information, such as vessel name, call sign and MMSI. This will be integrated into the distress call procedure along with the coordinates of the alert.

 

The screens offer brief reminders on the best techniques to rescue an MOB when under sail and when under motor.

 

The emergency number feature allows you to pre-select your local emergency number, such as 112 in Europe. This feature is accessed in Emergency information.

Alternatively there is the option to enter a personal emergency number such as a sister vessel contact number.

In an MOB situation you can select which number you wish to call.

 

 

Manual Alert Activation (No Tags)



The OLAS MOB feature works even if a Tag is not connected to the APP.  The MOB alert can be manually activated from the current data page.

This feature will be available free of charge for 1 month, after which the APP will cost £4.49, €5.49, US $5.79.  It is free once a Tag has been synced with the APP.

OLAS Advantages

 

Each Tag can be named individually and allocated to a person or object such as a dan buoy.

In the Synced Tags page you can either deactivate the Tags individually or all at once. Once deactivated each OLAS Tag can be switched off without causing an alert.

Alternatively you can deactivate and switch of the Tag simultaneously. If it is switched off within 0.5 meters of the phone it will deactivate the Tag and the Tag itself will also be turned off. If you switch it on within 0.5 meters of the phone it will automatically reactivate the Tag.

If the OLAS tag is switched off within 0.5 meters of the phone it will deactivate the Tag and the Tag itself will also be turned off. Switching on the tag will automatically reactivate the Tag if in range.

The OLAS Tag will last roughly for 6 months if left turned on. However, to preserve battery life it is advised to switch your Tag off when not in use. The Tag battery status is displayed in the Synced Tags page. If the Tag’s battery life falls below 5% an alert is made to warn that you need to replace the Tag.

False alerts may occur due to a connection break, such as someone jumping ashore. This can be simply cancelled by bringing the Tag back into range or by manually cancelling the alert on the phone.

With a clear line of sight your OLAS Tag connects with the APP for up to 50 meters range.  However it is advised that the OLAS system is used on yachts up to 50ft (15.25m) as other elements, such as masts and superstructures, can cause signal loss. It is important to keep the mobile/tablet in a location which achieves connection at all points, this should be checked when the Tags are initially synced.

Note : Carbon and aluminium hulls will block the connection. If used in carbon or aluminium hulls it is important that the device with the OLAS APP is close to the hatch so a clear line can be achieved for connection.

Example Scenarios Afloat

 

There’s one helm on deck and the other(s) below deck due to bad weather, sleeping, shift rotation, making a drink etc.

The helm sets the autopilot for a quick adjustment to the sails. A simple misplaced footing or bad wave...and then they are overboard without anyone noticing, when or where this happened.

OLAS will send an immediate alert - as soon as the Tag hits the water.

Often the skipper is managing the majority of the jobs, sail changes, reefing etc. This may leave less competent crew in charge of the helm.  An involuntary gybe or loss of balance and the skipper is overboard. In full view of the other crew. However, the crew is inexperienced and liable to panic. They will take time to drop sails and switch on the engine. 

By now the skipper can no longer be seen. A Mayday call needs to be made but in the rush to take the sails down no-one remembered to press the MOB button on the GPS. The original coordinates are unknown and the crew are having to search through booklets for the correct MAYDAY procedure.

OLAS records the time, and exact co-ordinates when the Alert goes off

At anchor, in port or even by a swimming pool you want your children to feel free to run around.  But a simple trip and they can be off the dock or boat and into the water.

If they are wearing an OLAS Tag the alert will sound when they fall in.  Your mobile device can be connected to an external speaker system to ensure the alert can be heard above local noise.

LIVE Current Data Display

 

Speed over ground (SOG in knots)

Digital display of the vessel's speed over the ground in knots.

Top recorded speed over ground (SOG knots)

Digital display of the vessel's top speed over ground. You can reset this if required.

Vessel course

Compass bearing which takes into account the vessels previous 30 meters of travel to generate an average course heading

Phone/Mobile Device bearing

Displays the real time bearing of the direction in which the phone is being pointed

Bearing to waypoint

If you enter the GPS co-ordinates to a waypoint OLAS will display the bearing required for a course to that location.  

Course to steer

If you know your course to steer to arrive at a specific waypoint you can enter this information and track if you are maintaining the correct direction.
