Yacht Sentinel® is the ultimate boat monitoring system, allowing you to keep a constant eye on your motor vessel or sailing yacht – whether it’s on swing mooring or in marina.

GPS and GSM capable Base Station upgraded firmware to take the new Passive Infra-Red movement sensor with GSM elbow stub antenna, External Sensor Connector, and 12vDC/24vDC Power fly lead. All you need to get up and running.

How it works: 

Yacht Sentinel is able to monitor a wide range of sensors and boasts state-of-the-art technology. The heart of the Yacht Sentinel is the AVR XMEGA 32A4u low power, high performance 8/16-bit AVR microcontroller.  In addition to this, Yacht Sentinel has the latest in Global Positioning Satellite receivers, a SiRFstarIIII receiver 20 channel receiver featuring fast satellite acquisition with an internal ‘ patch’ antenna packed into a module 12mm x 12mm  removing the need to have a complicated external wired antenna. Finally to communicate with the use via SMS (text) a Telit GE865-Quad band GSM modem is integrated, effectively a mobile phone on a chip. This module is capable of working world wide due to the fact that it uses all four of the major GSM frequencies used by mobile providers in all continents worldwide.  

The microcontroller is responsible for communicating between the various sensors and modules and for directly detecting and processing all the internal and external alarms. The microcontroller communicates with the GPS receiver to obtain tracking data of the Yacht Sentinel position, then calculates geofence alarms and also provides Course Over Ground and Speed Over Ground in knots and additionally the Longitude and Latitude of the Yacht Sentinel. The microcontroller then converts the GPS and alarm/status data into a text format and commands GSM module to send this information to the users mobiles. Likewise when the user sends setup data and status requests to Yacht Sentinel, then this is collected from the GSM module by the microprocessor and processed accordingly.

The Yacht Sentinel is truly in a class of it’s own for functionality and capability and price, it is a perfect combination of British Invention and German Manufacturing.

Who is it for?: 

Yacht Sentinel is designed for all boat owners, whether sail or power. A boat is a major investment and like any major investment we want to protect it. By the very nature of boating we can’t be on our boat all of the time and there will be some times when we have to leave our boat at a mooring or in the marina, sometimes for extended periods when our boat is some distance away or in another country even.

As a boat owner myself I wanted to be sure that when I was away from the boat I could be confident that the shore power was still on or that the boat battery was in good order and that the bilge was not filling with water, we have all heard horror stories of boats sinking at their moorings due to the bilge systems failing due to a simple float being stuck, or that the batteries have failed. During the winter periods it is especially useful to know if the temperature drops below zero and to be sure that the heaters are doing their work and that the dehumidifiers are working. There is also the concern of intruders breaking into the boat especially on swing moorings or even if the boat has been moved or stolen without your knowledge. I designed the Yacht Sentinel to monitor all these things.

Yacht Sentinel is also flexible, and enables the user to provide alarms specific to local needs, for instance in the lake district where some pontoons are fixed, during heavy rainfall the lake level rises and in 2009 up to 20 boats sank because they were moored to a fixed pontoon. One owner now has fitted a tilt switch to Yacht Sentinel that now sends an alarm in this situation.

Yacht Sentinel gives me peace of mind that I will be informed quickly should any problems arise, and the fact that Yacht Sentinel will inform up to three users at the same time, it means that you can nominate someone close by to react quickly if you wish. A small investment to protect a big investment!
