Routing and usage precautions

With the advent of powerful weather-routing applications on our tablets and smartphones, as Weather4D and SailGrib WR, at truly affordable prices, routing is becoming more popular for pleasure boating.

Apps de navigation : the (rares) new products in Spring 2014

The least I can say, it’s that the new things don’t jostle. After the frenzy of announcements of 2013, the developers seem to be marking time. It is likely that the proliferation of navigation apps should not promote their profitability, and that the financial return on investment in development and maintenance time should not be obtained by everyone. Navionics charts remains the undisputed leader. By creating its new “Boating” formula to complement and/or replace “Marine” (¹) it revives sales which were probably starting to run out of steam. iNavX remains the best-selling independent application in the USA, and the rest of the world through combination with Navionics cartography, and particularly in France thanks… to the strong promotion to which I contribute.

With the basic 1.3.3 and PRO versions 1.3.9 delivered last November, Weather4D had replaced the GRIB files fine grid from Great Circle by its own files based on the U.S. model WRF (¹), computed under his own steam. These files cover Europe, Greece, Canaria, Azores, Greater and Lesser Antilles, offer a resolution of 0.1° (6 NM) up to 96 hours by 1 hour steps. The data provided is the same as the GFS model (¹). At the same time, The annual subscription price has been reduced by 60 to 30 €.

Thanks to the implementation of new means, the next updates that have just been submitted to Apple Store will provide even more details. Olivier Bouyssou explains :

« FYI, App4Nav uses 6 different servers, 2 for the calculation of WRF model and 4 for distributing GRIBs : 2 for the US+Asia region and 2 for Europe. At this time 8000 GRIBs are distributed per day and triple during the season… ”

This now enables to provide, for the French coasts, including Corsica, ultra-fine grid to 0.04 °, that to say 2,4 NM. It also adds to the GFS and WRF files new data evaluating wind gusts. Read more …
