two things drove me to a plotter. Display of radar and weatherproofing. I can use an Ipad down below.... When I get one.

Garmin's nav app
Check out Garmin's Blue Chart Mobile, just released. The app is free but charts cost: both the East and West Coast of US for $29.99. It also has activecaptain as a cruising guide.
I have Navionics, Navimatics, and Jeppersen's Plan2Nav but on initial usage Garmin's Blue Chart seems to have the most potential.

Can't use the new Garmin app on a 1st generation I-pad. Apple is NOT supporting IOS 6 on the first gen pads. The Garmin app is built in IOS 6. According to the internet and you can believe everything on the 'net (right?), the First generation I-pads don't have enough power to run 6. Oh well, I'm not upgrading just because Apple wants me to. Besides, I ticked off at Garmin at the moment about not supporting my chartplotter anymore. I'd rant about it but it's a WHOLE nuther topic.
My 'research' and discussions with local 'Apple tech' seems to indicate that the 'gps' function on iPads is not 'true' GPS but rather a dependent primarily on WiFi/cellphone connections .... GPS 'adjacent' is not really GPS and if one is not within range of a reliable Wifi source, the reporting of GPS signal during transits beyond Wifi/cellphone signal is 'stored (within the iPad) and delayed' ... therefore such 'accuracy of actual position would be highly suspect' when beyond the normal range of such 'towers'.
Can anyone using an iPad for navigation beyond WiFi or cellphone tower range confirm this?
GPS is scheduled in the future to be eventually be replaced with NAVSOP (Navigation via Signals of Opportunity) .... based on 'expected' signals that regularly broadcast ... radio stations, etc. However this is only in the development stage.

Don't need cell or wifi. gps comes with phone capability
We chose Verison, but never activated the I pad.
GarImin Is on
my S$&t list and I am not a Jeff Seagull fan. Navionics works well enuff to dazzle sailmate and others

your "tech" is only partially correct. That's true of the ipads without cellphone option. If you get the ipad with the cellphone radio, it also includes a real GPS that's quite accurate
Not sure which forum it was...but was discussed at some length....We use IPads for our Nav charts......two are wifi only(only receive GPS through Bluetooth) ....one has 3 g with built in GPS. The 3g version receives GPS at the flight levels....5 meter accuracy......we were no where near land.......I don't believe that 5 meter accuracy is available with cel based location......correct me if I'm wrong.......

I just bought the wife an iPad 4(retina display and cellular package with built in GPS) that I intend to use on the boat for navigation. I have been researching waterproof cases and found this one that seems to fit the bill nicely, although it is a little pricey.

Now I have to determine how and where to mount on my binnacle.....

That could be a problem. I use and like a RAM mount, but it wouldn't hold that case. I have a full enclosure, and the admiral always has gallon ziplocks, so it never occured to us to buy a case and let the Ipad rattle around on the seats.
My wife just got "her" xmas ipad last week. I installed the Navionics app and the $5.00 upgrade. Works like a champ without activating the cell phone service. We have Sprint in our area and can get data service for a monthly $20.00 if we feel we need it on a cruise. We also bought a Griffin survivor case on Amazon. Not waterproof but splash proof. I plan to Velcro the iPad to the cover of my radar screen which I seldom use. I will need to figure out a way to hook up external power since the GPS seems to really use the battery.
An interesting side note........We were returning from Aspen to Chicago yesterday and noticed the DUAL GPS doesn't update as quickly as the built in IPad GPS. Our ground speed was 628 knots, yet the DUAL GPS only showed 18. The IPad with GPS using Foreflight did show our ground speed correctly at 722 mph. Accuracy was still good. Apparently the the onboard GPS updates continuously rather than once per second or so. Not really a concern on a boat, but found it interesting........Happy Holidays all........

Not a concern on boats, but an annoyance. Numbers displayed bounce all over. I didn"t know if it was Navionics or Apple, but it is obvious there is no averaging.
PS got 2.1 amp charger set , 110 and 12 volt, at Home Depot for about $15. Seems to allow navigation without running battery down. 1 amp chargers that came with will not meet demands of GPS + nav software.

This is a good thread. I am considering using Navionics app on the Galaxy pad. I was hoping you could answer two questions for me:
1) How does the indicated position of the vessel compares to the one on your chartplotter vs visual observation
2) Do Navionics charts include bathymetric lines and if so, do you find them accurate?

Positions are identical as near as I can tell. Both units use Navionics charts, and there are some discrepancies. Lots of canals in my neighborhood. Sometimes both show the boat on land between canals, but so did my old Garmin Bluechart unit.
Navionics is the same stuff as on my Raymarine A50D but brighter, clearer. and BIGGER. yes depth countours, color differentiation of shallows etc.

Pic shows difference. We can both see the chart on Ipad, don't need to get our nose up to the Ipad and look through bifocals like we do with the Raymarine. And the zoom capability is awesome.

He's wrong. Only the non-3G iPad are WIFi location only.
The 3G iPad uses a hybrid approach for generating fixes as described:
If the WiFi radio is on and signal present:
The location service host at apple will compare the sniffed MAC addresses found by the radio and then generate a rough fix with an EPE of maybe 100 feet. The iOS will report this initial fix to the apps.
If the 3G radio is ON and signal present:
The location services host at apple will generate a rough fix based on Cell tower ID and report this to the iPad. The iPad will give an initial fix with a EPE of several hundred meters.
If a rough fix can be generated by one of the above technologies then the apple services host will also generate a GPS ephemeris set for current satellite locations and download this to the GPS chipset. This is important because the built-in GPS chip in the iPad is a low cost, low correlator model that can use the help warm starting. This is the so-called A-GPS technology.
If no 3G or WiFi data is available, the GPS chipset will warm start or cold start depending on if the almanac data is still current. If it is not, it can take several minutes for the chipset to download the ephemeris data and start.
All of this is totally transparent to the applications. If fact, so is the presence of an external GPS device. And if you plug an external GPS into a GPS enabled iPad, the OS will use the more accurate of the fixes to report position.
After it gets a GPS fix, it is as accurate as a traditional handheld GPS unit. How accurate it maps and plots if purely a function of the application.
Pretty smart.
