New Simrad AI50 Class B AIS Transponder
Class B is limited to 2 watts output, but that is enough for all normal use
and provides quite reasonable range, around 10 nm between 2 boats with
mast mounted antennas and 5 for lower mounted antennas. It bounces around
just fine in the Swedish archipelago.
I sailed 1200 nm this summer with ClassB on board and met a number of
other boats with ClassB. There are already over 100 ClassB transponder in
operation here in Scandinavia.
Haven't seen anyone yet with the Simrad unit though.
