Great reference. I may give it a shot next season.
However, it seems more than unlikely that an Ipad can be software programmed to directly receive AIS signals. They must be transmitting over the 3G network, which would mean it is land based. Try shutting the 3G/wifi signal off at home and see if you get data before and after. Or, try from your living room to see traffic in Narragansett Bay, which you could only get over the internet.
Nevertheless, if they've improved delivery time from the land based receivers to the app, that's a good thing.
