Installation of AIS transponders

Jump back in time ten years; AIS receivers are commonplace on leisure boats but transponders are only found on commercial vessels and offshore racing yachts. Skip forward to the present day and, well, see for yourself;


On average, Berthon installs an AIS transponder every month. Whilst it is not a replacement for radar, it is certainly used far more frequently. Stand-alone units are still available, however, integrated systems are much more popular. Installation involves fitting a transponder, with its own power supply and mounting the transponders dedicated GPS receiver. Either an additional antenna or more commonly, a splitter is also required and finally, a link to a chart plotter via NMEA2000 or 0183. Once all is connected the unit will need to be programmed with the vessel name, MMSI number, call sign, length and type.

For more information about upgrading your yacht’s electronics please visit our marine electronics page or contact our electronics manager Henry Castledine.
