Weather4D 2.0 revisits navigation on iPad [Update]
Weather4D 2.0 is available sur Apple AppStore (*). After the success of the first two versions, APP4NAV company just revisit chart navigation on iPad and iPhone by integrating the timing dimension. With simulations and weather routing, navigation becomes predictive, allowing a constant anticipation of future weather conditions and sea state. This “navigation into the future”, relied on the quality of meteorological and oceanographic predictions today available, was designed in order to bring a new dimension to the safety of boaters.

iPolar 2.0 and new Weather4D have arrived
iPolar 2.0 arrives with several improvements, including one expected from the beginning : the possibility of exporting fleeces by email. Done, and moreover the export of fleeces (single or multi-sail) is systematically done in 3 file formats : CSV, TXT and POL. Enough to reuse the fleeces with any application on Mac, PC or other mobile devices.
The dream !
Iridium GO! keeps its promises [Update]
Since its announcement last February, and GO! took a long time to arrive at retailers until the beginning of this month. The company E-SAT gave me one to conduct some tests. Although too late to carry out these tests at sea, the Quai des Antilles on the Ile de Nantes offers a wide sky clearance also than the deck of a boat, enough to connect satellites of all-round. Two types of tests were carried out : requests and receipts of GRIB weather files from an iPad featured with Weather4D PRO app, functions related to telephony from an iPhone.
Weather4D still makes greater finesse
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. Ces fichiers couvrant l’Europe, Greece, Canaria, les Açores, Greater and Lesser Antilles, offrent une résolution de 0,1° (6 NM) up to 96 hours by 1 hour steps. Les données fournies sont les mêmes que le modèle GFS (¹). At the same time, le prix d’abonnement annuel a été réduit de 60 down to 30 €.
Grâce à la mise en place de nouveaux moyens, les prochaines mises à jour qui viennent d’être soumises à Apple Store vont fournir encore plus de détails. Olivier Bouyssou explains :
« Pour info, App4Nav uses 6 different servers, 2 for the calculation of WRF model and 4 for distributing GRIBs : 2 pour la région US+Asie et 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 …
iOS7 and navigation applications
The latest version of the iOS operating system for iPad, iPhone and iPod Touch have caused their share of compatibility updates. This time, with iOS7, developers have had hard work to put their interfaces in accordance. As far as we are concerned, the latest versions optimized for iOS7 to date are :
- iNavX 3.7.0
- iSailor 1.5.5
- AyeTides 3.0 (iPhone) and AyeTides XL 2.0 (iPad )
- Weather4D 1.3.2 and Weather4D PRO 1.3.7
ENCs, Routing and sailing shaves stone
The relationship of a recent experience of an iNavX user and Weather4D PRO routing function invites me to bring a warning to the attention of novices boaters in computer use.
A regatta course, départ de St Hélier (Jersey) to arrival Granville, optimized with Weather4D PRO using fine grid GCWF model and MyOcean currents prediction, donnait la route suivante dans iNavX :
The optimized route transferred to iNavX
Weather4D PRO 1.3.3 further improves routing
Improvements…
No respite for this application : two and a half months after integrating the currents into the routing calculation, this latest version provides significant advances on this function. The improvements bring greater precision to the calculation of the optimized route and new parameters allow for fine-tuning.
… and two pieces of good news :
They concern currents, follow the leader… Read more …
Weather4D PRO 1.3.2 adds the currents in the routing
With the version 1.3.2, Weather4D PRO allows to get and display currents as GRIB data. To begin with, currents available are provided with subscription by Tidetech, I mentioned there in the past (¹). Once entered in Weather4D PRO settings a username and password, provided at the time of subscription, you can access Tidetech global catalog.
Only one PRO subscription to Tidetech allows you to obtain files in GRIB format. The company is considering a specific offer for applications on iPad / iPhone. Read more …
iPolar generates speed polars for Weather4D PRO
You dreamed of it since Weather4D Pro has featured its powerful routing module. He did it !
Our Toulousian crazy developer, Olivier Bouyssou, just sent Apple a new app : iPolar.
Developed in collaboration with — and on behalf of — KND SailingPerformance, iPolar calculates the performance polars of a sailboat based on specific parameters, Easy to identify : Read more …
