What is a easyAIS receiver?

An 'easyAIS' receives AIS radio signals, both Class A (issued by the commercial shipping) and Class B (issued from a growing number of recreational vessels). The received signals are converted to NMEA messages and presented on a plotter with AIS function activated, or on a PC with a chart program installed. 

What is the benefit of AIS information for a recreational sailor?

AIS information should be considered as a security for recreational sailors. Especially in reduced visibility like fog, rain or darkness, it is a great advantage to be able to see the surrounding vessels over 300 Gross tons, and smaller vessels with an AIS transponder Class B.  

With an 'easyAIS' receiver connected to a plotter or a PC, you have an overview of vessels that broadcast AIS information. The information presented on a plotter or PC, from the surrounding vessels are: ship name, MMSI number, call sign, position, speed, course, CPA, TCPA, etc. 

How to connect an 'easyAIS'

The 'easyAIS' needs to be connected to its own VHF antenna. Alternatively, use an ‘easySplit’, which connects to the existing VHF antenna. An ‘easy split’ divides the antenna signal between VHF radio, and possibly easyAIS and an ordinary FM radio.

• The unit is delivered including data cable for connection to the plotter or PC.
• The latest models of chart plotters are able to present AIS targets.
• Examine your plotter specifications before connecting an ‘easyAIS’.
