The Vesper Marine WatchMate WatchMate XB-6000 High Performance Class B AIS Transponder
Unlike any other AIS the high performance Class B AIS with built-in NMEA 2000 gateway and internal GPS, XB-6000 integrates AIS, GPS and NMEA information so that you can see your safety and navigation on any AIS-capable chart plotter or MFD. Or use your PC and Mac for easy computer navigation. Easily integrate AIS to your existing marine electronics and convert NMEA 2000 & 0183 instrument data to USB, facilitating 3rd party navigation software.

Complete Class B AIS Transponder
WatchMate XB-6000 is a Class B AIS transponder with a two-channel parallel receiver and transmitter. It transmits your vessel position and details and receives the same kind of information from other vessels with AIS transponders.

The AIS data is sent every few seconds and includes information such as course, speed, latitude, longitude, and heading. Static information about the vessel is sent every few minutes and includes the name, type of vessel, length, beam, draft, etc.

Certified NMEA2000 Gateway-Built in
Translates NMEA 2000 instrument data (heading, wind, depth, speed, log, temperature) and routes it over USB and NMEA 0183.

All NMEA 2000 navigation data is combined with GPS and AIS data and sent to computers via USB. Display and use this data in your navigation applications on Windows and Mac navigation software.

Simply plug the XB-6000 into your NMEA 2000 network and your integration is done. Or connect it to the NMEA 0183 input on your chart plotter. And if you have a mixed network you can even use the XB-6000 to integrate the two by connecting your XB-6000 to your NMEA 2000 navigation instruments and a NMEA 0183 chart plotter. The XB-6000 makes your new NMEA 2000 instruments appear on the chart plotter!

High speed 5Hz GPS navigation and built-in GPS Antenna
A built-in 50 channel GPS receiver (with WAAS/EGNOS) and its own internal GPS antenna eliminates the need to install an external GPS antenna in many situations.

However, it also includes a powerful external antenna for those installations that require it. The external antenna can be pole mounted on standard 1" threaded tubing or mounted on a flat surface with the included base. The cable has a small connector, about the same diameter as the cable, to facilitate easy routing through small holes.

The fast 5Hz GPS update rate results in higher resolution and smoother tracks on your plotter or MFD, even during high speed maneuvers. It can be used as a source of GPS data for the entire NMEA 2000 network.


  • NMEA 2000 / 0183 and waterproof USB.
  • Compatible with all NMEA 2000 certified chart plotters and MFD’s.
