Q: I have an iPad 1 but I can't seem to load SEAiq on it?
A: The SEAiq apps now require at least IOS version 6.0.  Unfortunately, Apple ended support for the iPad 1 with IOS 5 and so SEAiq can no longer be installed on the iPad 1 and users that already have it can no longer upgrade to newer versions.  Please keep in mind that when you purchase SEAiq apps or premium upgrades they are good for all your Apple devices.  So when you buy a newer iPad, you can upgrade/install SEAiq for free.

Q: All I see is a globe of the Earth.  Where are the charts?
A: All of the SEAiq apps include a base chart of the Earth but otherwise do not include other charts.
SEAiq USA expects you to download the latest charts from NOAA for regions you are interested in, so it does not come with any charts.  When you have a data connection, click on the NOAA button at the bottom of the screen.  It will download the most recent NOAA chart catalog and allow you to select which regions you want, then press Update to download the charts.  Note that downloading charts can use a bit of bandwidth so you may want to download them when you have a WiFi connection.

Q: For SEAiq Open, how are charts loaded onto my iPhone/iPad?
A: When you first start SEAiq Open, you will be guided to simple (and detailed) instructions (go to the Charts tab and press the Help button).  Here is a quick summary.  1) You use a free tool (Windows) or built-in program (MacOS) to create a single zip file from your directory of charts.  2) With your iPad/iPhone plugged in, you run Apple iTunes and go to the bottom of the Apps tab, select SEAiq Open, select Add File..., and identify the zip file you created.  iTunes will then transfer the zip file with all your charts to your iPad/iPhone where you will then be able to view your charts.

Q: Are Inland ENC charts supported by SEAiq Open?
A: Yes

Q: I downloaded charts when I first installed SEAiq USA/Free.  How do I get updates for the charts?
A: NOAA publishes updated charts very often (sometimes several times a day).  To download the updates, go to the Charts tab.  SEAiq USA/Free will download a new NOAA chart catalog and identify which regions have new or updated charts charts in red.  Just press Update to download them.

Q: How do I get to see the charts I just downloaded?
Q: How many charts can SEAiq handle?

A: SEAiq uses the standard Apple gestures, including pinching (placing two fingers on the screen and moving them together or apart) for zooming, and panning (placing a finger on a location and moving on the screen) to move the location around.

A: There is no limit to how many charts SEAiq can handle.

Q: How do I find the details for an object on the screen?
A: Double tapping on the object and then select "Details for this location".  You will be presented with a menu of features at or near that location.  Features may correspond to icons, lines, or areas. Select any feature you are interested in and it will display details for it.

Q: Is there a legend explaining all the symbols?
A: SEAiq uses standard symbols.  We do not provide a legend and instead recommend you use the "Details for this location" feature described above to examine any symbol on the display you are not sure about.

Q: How do I get SEAiq to personalize the chart display to the features of my vessel?
A: Go to the settings window and set the values for Shallow Depth, Safety Depth, and Deep Depth.  Shallow Depth and Deep Depth control coloring of areas.  Safety Depth controls the presentation of hazards; for example depth soundings less than your safety depth will be colored black (to highlight them) and the others will be grey.

Q: How do I get the display to center on my vessel?
A: There are several ways to do this.  The simplest is to touch the arrowhead in the top-left corner of the Navigation Window.  Click on settings and turn on "Follow Vessel".  Alternatively, you can double tap on the Navigate display and enable "Follow Vessel" there.  All of these methods have the same effect.  Note that as soon as you pan the display, the Follow Vessel setting will be disabled for you.  Our free apps, SEAiq Free and SEAiq Open, require purchasing the in-app upgrade to enable the Follow Vessel feature.

Q: Some information about an object is not being displayed.  How do I find it?
A: Vector charts contain much more information than can be displayed for you.  However, you can find out all the details on any object.  Double tap on the location and select "Details for this location".  All objects close to where you tapped will be displayed.  Select the one you are interested in and you will see all the available information on it displayed for you.  For attributes with large amounts of text, you will need to tap the blue disclosure button on the right side of the display.

Q: How do I tell what units are used?
A: Units are displayed in the Legend portion of the Settings window. You can also change the units there.

    1. I think your are saying your iPad was stolen and you need to reinstall SEAiq on another iPad. For SEAiq USA, you can install it again from the iTunes store. For SEAiq Free/Open/PIlot, you can install the app again for free and then go to the Store tab and press the Restore button. If you have any questions, please send an email to seaiq.info@gmail.com.

  3. How much memory do the charts & APP require? Should I consider this as I figure out which ipad to purchase?

    1. Most users won't have more than 1-2GB of charts. All your charts will fit in a 16GB iPad. However, you should consider your total storage needs when choosing your iPad size. For example, if you plan to keep lots of music, pictures, movies, you should factor that in as well.

  4. how can I get Seaiq onto my Windows 7 Lap top

    1. Sorry! SEAiq is currently only sold for Apple iPads, iPhones, and iPod touch devices.

  5. This download of is my first attempt at using an app of this type. I have never used a marine GPS and am not familiar with a chartplotter. SEAiq is currently on my iPhone 5, but I do not have my boat in the water yet (wanted to play with this first). Will SEAiq on my phone (or iPad if I get one) serve as a GPS. Is a chart plotter something I have to have, or does the display on my phone cover this function? I am confused about using a chart plotter with the app (I have seen this suggested in reviews of this or comparable apps) when I assume the display on my device covers this. I expect that I will be able to follow the movement of my boat on the water the same as I do my car on my iphone. Sorry for the dumb questions.

    1. You iPhone 5 has an integrated GPS and SEAiq will work with it in a similar manner to the apps for cars. You do not need a chart plotter for GPS.

      As a general comment, we support SEAiq on iPhones, but the small display size makes them of questionable usefulness in real life. They are helpful if you need to check something quickly.

      You will find an iPad much more useful than an iPhone because of the larger display size. Be sure to not get a wifi-only iPad as they do not include integrated GPS hardware. See "Choosing an iPad" for more information on this.

  6. I loaded CM93 charts and Google kap charts onto the iPad. When the Google pictures are displayed the underlying vector chart is not visible, so no chart date is available, like depth, buoys, etc. Is there a way to do the overlay and still see the vector chart??

    1. Currently, there isn't a method to use transparency to display multiple charts together.

  7. Are available user manual in spanish?

    1. You can get a machine translation to spanish by going to http://doc.seaiq.com.
