From SEAiq version 4.0 (released December 2015) CM93 charts are no longer supported. On Zen Again we have been using CM93 vector charts and KAP raster 'charts' (produced from GoogleEarth imagery using GE2KAP) in OpenCPN as an aid to navigation. See our from 2012 on the latter. Ever since then we have been under the impression there was no software to present this information on our iPads.
During our cruise through SE Asia we found no-one who knew of such software. Today we discovered we were all wrong!
Thanks Carolyn for pointing us in the right direction. There is an app which can display CM93 and KAP charts on iPad. Is the answer and it is brilliant.
Within minutes of downloading and installing the app I had installed our CM93 charts. A few minutes later I had a few KAP files installed too. Once aboard Zen Again it took only a few minutes to configure SEAiq to accept AIS, GPS and instrument data from our Vesper XB-8000 AIS over WiFi. The two screenshots below show example KAP and CM93 views, both of Direction Island in the Cocos-Keeling Islands. Changing between the two involves switching one setting (Raster Charts On/Off).

The Status Bar the top of the screen is now populated, Zen Again is the black ball and AIS targets are shown.

Simplified CM93 View of Fremantle and Gage Roads SEAiq has a good table view of AIS targets. The information page for each target is very detailed.

AIS Targets Page Individual AIS Target Page SEAiq also supports email requests for and display of GRIB files. It will generate an email request to send to SailDocs. It would be nice to see the range of GRIB providers expanded. Weather Page SailDocs GRIB Request Email I later loaded a set of several hundred KAP files. This wasn't as straight-forward as I had hoped but I eventually got them all installed and working. I used iTunes to transfer both CM93 and KAP files.
The two issues I have found so far are:. Some zip files containing kap files are not accepted by SEAiq, despite successfully loading the same set of files individually. Unsurprisingly SEAiq gets a little slow if a large set of KAP files is loaded Update (20 April): The zip issue has been identified by SEAiq as the presence of Mac OS X hidden files in zip files. These files have names like MACOSX and.DSStore and can be searched for in zip files using the command unzip -l (without the square brackets). If such files are found use the command zip -d 'MACOSX.' '.DSStore.” to remove them from the zip file.

The next release of SEAiq will ignore these files. It is surprising that SEAiq is not listed when one searches for 'marine navigation' in the App Store. I think that explains why we've never heard of it before. I have mentioned this to the SEAiq folks. Update (20 April): SEAiq will be listed under 'marine navigation' from its next release in the App Store. One thing's for sure - SEAiq is a very useful iPad app for sailors who need their charts supplemented by GoogleEarth imagery.

It is a very nice chartplotter generally, but the support for both CM93 and KAP charts sets it apart.
