![]() He happens to be an accomplished sailor and a very talented programmer. Mark's many ocean miles have given him a unique perspective on what features are valuable for crossing oceans as well as coastal cruising. You can follow all of their travels on their Northfork blog. They plan to continue their adventures in the Mediterranean. Congratulations Mark and Dana! The last leg of their trip was from South Africa to Cape Verde where the boat will remain until baby number 2 arrives shortly. Concerns about pirates forced them to cross the Indian Ocean and onto South Africa. Their son joined them as they spent many months exploring the coasts of Australia and eventually moving on to Southeast Asia. Mark and his growing family arrived back at their boat in Australia with an added crew member this year. I originally reviewed the SEAiq USA app back in April of 2012. He has not only sailed more than 15,000 miles this past year but also has made many valuable additions to his SEAiq charting app. ![]() Mark Hayden, the author of the SEAiq series of apps, has been very busy lately. Very cool.Cost: SEAiq USA $9.99, Free version, SEAiq Open $19.99 It is a very nice chartplotter generally, but the support for both CM93 and KAP charts sets it apart. One thing's for sure - SEAiq is a very useful iPad app for sailors who need their charts supplemented by GoogleEarth imagery. Update (20 April): SEAiq will be listed under "marine navigation" from its next release in the App Store. I have mentioned this to the SEAiq folks. I think that explains why we've never heard of it before. It is surprising that SEAiq is not listed when one searches for "marine navigation" in the App Store. The next release of SEAiq will ignore these files. If such files are found use the command to remove them from the zip file. DS_Store and can be searched for in zip files using the command (without the square brackets). Update (20 April): The zip issue has been identified by SEAiq as the presence of Mac OS X hidden files in zip files. Unsurprisingly SEAiq gets a little slow if a large set of KAP files is loaded.Some zip files containing kap files are not accepted by SEAiq, despite successfully loading the same set of files individually.I used iTunes to transfer both CM93 and KAP files. This wasn't as straight-forward as I had hoped but I eventually got them all installed and working. I later loaded a set of several hundred KAP files. It would be nice to see the range of GRIB providers expanded. It will generate an email request to send to SailDocs. SEAiq also supports email requests for and display of GRIB files. The information page for each target is very detailed. SEAiq has a good table view of AIS targets. Simplified CM93 View of Fremantle and Gage Roads This reduces clutter to make AIS targets clearer. Here's another view with CM93 chart detail set to "Basic". Success and Fishing Boat Harbours close up The Status Bar the top of the screen is now populated, Zen Again is the black ball and AIS targets are shown. The two screenshots show the presentation of CM93 charts in Fremantle with WiFi data enabled. KAP file GE image of Direction Island (Cocos-Keeling)ĬM93 chart of Direction Island (Cocos-Keeling) Changing between the two involves switching one setting (Raster Charts On/Off). The two screenshots below show example KAP and CM93 views, both of Direction Island in the Cocos-Keeling Islands. 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. A few minutes later I had a few KAP files installed too. Within minutes of downloading and installing the app I had installed our CM93 charts. There _is_ an app which can display CM93 and KAP charts on iPad. Today we discovered we were all wrong! Thanks Carolyn for pointing us in the right direction. During our cruise through SE Asia we found no-one who knew of such software. Ever since then we have been under the impression there was no software to present this information on our iPads. 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. From SEAiq version 4.0 (released December 2015) CM93 charts are no longer supported.
