GoldenGate: I just found out about Mais. Quite a neat toy for use near shore, when you want to see whats near you that has AIS. BUT, because it's dependent upon an outside entity (MarineTraffic) it can't be relied upon 100% But, it's still quite a neat app to have and use for fun.
Don't think I'd depend upon it in the fog though.
Saving my pennies for a real class A.
