Seriously, the use of class A AIS on private yachts of normal cruiser size is damn rare and offers little advantage to the typical yottie/cruiser over the old class B, and IMO zero useful advantage over the new B+.
I was just joking with you, Jim. "Never say never - the world is full of oddities."
I agree with your assertion. I don't regret provisioning
my Class A, but I got it nearly free just as I was about to upgrade my wonky CSTDMA Class B. I do appreciate the much better breakout box for interfacing it. My chief complaint with many of the transponders intended for recreational vessels is being confronted by a bundle of wires as opposed to a sealed breakout box with proper labeled terminals for interfacing. And I consider having an integral backup GPS
receiver to be an advantage.
The extra power of the Class A is nearly irrelevant, the higher frequency of transmissions isn't relevant when comparing 2 seconds (Class A) to 5 seconds (Class B+), and the concern over Class Bs being "filtered out" is a myth. I've seen no evidence that Class A gets more attention than Class B from other vessels. I have made use of the vessel-to-vessel texting capability of Class A, but that's just a "nice to have" feature and used only when the other vessel texts me first. Being able to designate your destination
port is also a nice to have. If advising someone else, I'd say: unless you're a radio
geek like me, get a modern Class "B+" (SOTDMA) transponder.
