First thing was which AIS and whether to transmit too, we found Technology Afloat who gave advice on all the options and we settled on the Comar class B transponder, even better Gavin at TA did a kit that contained everything. Two cables to go to the back of the boat only, GPS aerial and NMEA to the chart plotter.

The NMEA connector from the Rayamrine chart plotter took a bit of finding (in the base of the cockpit cable) but once found easy to select the correct port wires and solder the connections, The rest of the connections were behind the radio, however we decided to install the transmit suppressor in plain view.

We decided to go for a splitter on the vhf aerial, seems to work fine and the installation of both boxes is easy enough but do watch the length of the screws you use. We wired the power to the AIS via the navigation instrumentation feed as we don’t need to transmit any other time than when we would have our nav gear on anyway

Configuration was easy enough, starting with the Comar AIS software, which is connected by a serial connector, Take care with your MMSI as once entered that is it without a manufacturer reset. Then we set up the Raymarine via the soft key function and it all worked first time. Alarm went off as there was a diving vessel in the commercial marina transmitting and within the 6 mile alert I had set – well it was about 150 feet, but it shows it works
