Any experience and recommendations on Ipad navigation apps, and the functionality of Ipad GPS on a sailboat? I s full time wifi or cellular connection required, which makes this pretty unusable?

If I'm not mistaken, gps does not use wifi or cell signal. It gets its signal from the satellites. So, if an ipad is GPS capable, I'd suspect you could use it as a gps on a sailboat. I don't know how good their gps apps are for marine navigation.

I think it does need access to a network for downloading charts, at least my i phone does.

The navionics app is what I use on my iPhone. It has to have the internet connection to load and install the program, but after that all it uses is the GPS. The maps are stored in the phone's memory. I bought the Southern Lakes version for $9.99 and it has all the southern lakes of course, but it also has the southern coast and intercoastal waterways and bays... Everywhere I see us sailing in the near future.

I was looking at a stand alone GPS until I researched the Navionics app.

I have iNavX on my iPad.
It works without cellular or Wi-Fi. Uses the GPS in the high end iPad.
Maps are downloaded permanently into the pad, so everything works independently.
I've used it in the Carribean, the Pacific Northwest and am about to take it to Mexico. Works great!
Don't replace your plotter with it, it's not waterproof.But makes a great backup and planning tool.
Also works with Aye Tides to give tidal data and with Shipfinder as a sort of AIS but Shipfinder needs an Internet source.

So which is better, Navionics or iNavX? Navionics is cheaper, but has bad reviews, iNavX has great reviews but is costly. Any advice on which to buy?
