I had a look at the new Icom at Seawork yesterday. Can't say I was overimpressed, it's BIG, expensive & only a receiver. For that money I'd have expected a transponder, which would have been more impressive. The built it AIS target display is basic & wouldn't be easy to use on a moving RIB, most people will output the AIS data to a plotter which makes the built in display redundant anyway.
Just my 2 penneth.
