If you must equip with a Class A AIS unit...
I highly recommend the Furuno
It will cost you about $3000....and will work well for you...
St. Elsewhere, et al,
Actually the antenna height and location on the commercial
vessels with Class A AIS units, is likely the largest factor, compared to the low antennas on the pilot vessels, which can very easily have their signals blocked/attenuated by the waves....and the lower power combined with the possible signal losses from the slower update rate of the Class B units on the pilot boats as they roll/pitch in the seas, etc. to be secondary...

The larger question I have is why isn't the World ARC recommending better or more experienced skippers/crew, etc. rather than a Class A AIS??
Or how about complying to the ISAF Cat 0 regs???
(perhaps it a WARC rule
that stems out of "consistency is best" philosophy?? or maybe they just want to be able to conform to any/all changing national rules/regs that their participants might find over the next year or so???)
Oh, well....that's all for now....
