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.
