Good, safe & easy – AIS

Post from the Caribbean …

… actually from Le Marin on the island of Martinique. One of our customers sent a big compliment to the Weatherdock team and of course our products in this way – “great service, great equipment!”.

The trip started in Italy and went via Barbados and Cuba to Trinidad – “always good, safe & easy thanks to AIS”. That makes us happy. It is very exciting for us to see where our customers are traveling around.

Many Thanks for the Postcard!

A040 easyRESCUE-PRO 3





Our easyRESCUE Rescue Transmitters have a basic approval and do not have to be registered anymore!

easyRESCUE App

With the easyRESCUE app, up to 8 different MMSI numbers can be pre-programmed in the rescue transmitter via Bluetooth.


Apple iOS                                       Android

The new easyRESCUE-PRO3 combines the 3 most effective alerting and locating systems, AIS, DSC and 121.5MHz homing, in one unit – just to make rescue missions as fast and efficient as possible.

Via AIS emergency message all vessels with AIS receiver aboard in the vicinity of up to 15 nm and more around the victim, including the mother ship, are informed about the distress situation. Updated every minute, this alert message contains current GPS position as well as COG (course over ground) and SOG (speed over ground) of the victim in a drift. These information enable every crew to assist with the rescue.

Via DSC distress call up to 8 different vessels get a first alerting call within seconds after the AIS MOB easyRESCUE-PRO3 was activated in closed loop. The MMSI numbers can be pre-programmed into the beacon via Bluetooth with the free Weatherdock App. After the GPS fix is given, a second DSC distress call is send out in “closed loop”, containing GPS position of the victim. For the next 10 minutes the “closed loop” crews are able to acknowledge the incoming distress call. If the easyRESCUE-PRO3 receives no acknowledgement, the unit switches automatically into “open loop”, transmitting an “all ships call” to everybody into the GMDSS emergency network. This “all ships call” can be relayed by commercial vessels to forward the distress call to a coastal MRCC (maritime rescue coordination center) which are the sole stations to acknowledge the „open loop“.

Via 121.5MHz a so called “homing signal” is transmitted. With the respective receiving and bearing equipment the right direction to the victim can be found out of 3 nm distance. In situation when there is “no sight” to the victim this technology comes up with a high benefit. The closer the vessel is to the victim, the more precisely the life-saving bearing can be done.

The parallel activation of all 3 technologies is done automatically with rip cord and magnetic switch, as soon as the automatic life jacket inflates when submerged. The intended life jacket has to have a special pocket inside that was developed specially for the AIS MOB easyRESCUE-PRO3.

  • Automatic activation by water contact

German YACHT magazine once again tested AIS MOB devices available on the market for their strengths and weaknesses

In early August the well known German YACHT magazine worked out a huge test event at the Baltic sea. The goal was to find out which AIS MOB device is the best on the market available.

With very successful 88 from 100 possible points the AIS MOB easyONE from German Weatherdock AG gets the TOP grade of this challenge.

The big advantages of the easyONE which bring it on TOP of the list are,

• palm-sized
• self-floating in upright position
• without buoyancy aid
• usage with every automatic life jacket
• highest transmission range
• full stand alone functionality with automatic activation
• long battery lifetime of more than 24 hours
AIS MOB emergency transmitter can make the difference between saving or losing a life at sea. The current GPS position of the victim will be updated every minute and broadcasted to every AIS receiver system in the vicinity of up to 10 nautical miles and more. The transmitted data also include course and speed over ground of the victim in the current.

Weatherdock AG is proud to be the winner of this competition in front of other manufactures and we take this first place as an incentive to keep on working hard to realize the best products possible.
