SEAiq professional navigation on iPad

Posted on16 October 201311 th 202410 comments

A few days before going on a long trip from Toulon to Noumea, my friend Christophe Mahé introduced me to this application which had gone completely unnoticed by me. I sincerely thank him ! As it is never too late to do well, a few discussions with the developer allowed me to install this application on my iPad with all its options. SEAiq went live on the AppStore in April 2012. Its developer, Mark Hayden, is a Californian computer engineer living a good part of his time with his family or alone around the world aboard his Super Maramu, the happy man.

Charting compared, a mixed result

Posted on8 th 201311 th 202412 comments

Three weeks and 600 nautical miles of sailing between the mainland and the Balearic Islands have allowed me to test in live some of iPad maritime applications we have.

Warning : There is no question of making a point-by-point comparison between applications, but rather to highlight certain essential aspects of their use. On the other hand, applications used were up-to-date at the beginning of July. Developments are rapid, and updates may have occurred in August or early September that I did not have. Finally, the messaging app iNavX associated with Navionics charting available ~~from the X-Traverse server~~ for me is the "master-standard" marine applications. iNavX is the most complete application in terms of features to date, and Navionics charting (from the X-Traverse server, I specify) closest to the geographical reality observed by many users.
