Weather4D 2.0 is available 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 in 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.

Label : routing
iPolar 2.0 and new Weather4D arrived
iPolar 2.0 comes with several improvements, which one expected from the origin : the ability to export the polar by mail. Done, and more export of polar (simple or multi-voiles) is done systematically in 3 file formats : CSV, TXT and POL. What reuse polar with any application on Mac, PC or other mobile devices.
The dream !
Routing and safety precautions
With the advent of powerful weather-routing applications on our tablets and smartphones, as Weather4D up to SailGrib WR, at really affordable prices, Routing democratizes for boating. The quality of these applications already seduced the amateur sailors, and even some high-seas professional riders, but also a growing number of leisure boaters. Riders use the routing in the essential interests of performance, achieve the fastest route from one point to another, so leisure boaters are more focused on getting safer and more comfortable routes. For them, the concept of speed is used primarily to avoid periods of bad weather, and the optimized route to escape from areas where sea and wind conditions can be dangerous. The routing is also used in this : even in powerboating, you may try to avoid too much wind speeds or wave heights to ensure ypur crew comfortable and serene trip. But what credit grant routing ?

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, from St Helier (Jersey) to arrival Granville, optimized with Weather4D PRO using fine grid GCWF model and MyOcean currents prediction, gave the following route in iNavX :
The optimized route transferred to iNavX
Weather4D PRO 1.3.3 improves routing
Improvements…
No respite for this application : two and half months after joining the currents in the routing calculation, this latest version provides significant advances on this function. Improvements provide greater accuracy in the calculation of optimized route and new settings allow to fine-tune.
… and two good news :
They relate to current, follow the guide… Read more …
Weather4D PRO 1.3.2 adds the currents in the routing
With version 1.3.2, Weather4D PRO allows to get and display currents as GRIB data. At first, 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 during the subscription, you can access Tidetech global catalog.
Only a PRO subscription to Tidetech provides GRIB format files. 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 !
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 polar performance of a yacht according to specific parameters, easy to identify : Read more …
Routing comes up in Weather4D PRO 1.3
After several months of intensive development and testing, under the conditions mentioned in a previous post, Olivier Bouyssou propose to the date of Grand Pavois his latest release of Weather4D PRO 1.3.0. No additional cost, the routing module simply be added with the update !
Career as a software developer serving the technical engineering combined with a solid mathematical background (¹) allowed him to develop routing algorithms which have nothing to envy to the market leaders (²). Added to an interface that is unanimously, this new advanced feature that will appeal to both racers and cruisers, want to optimize their trips in the best conditions of safety and comfort. The new features will :
Routing :
- Routing isochronous mixed (sail and motor).
- Setting a percentage efficiency of polar.
- Management of polar combined with multiple sails sets.
- Refreshment of a route from actual location.
- Importation of polar (CSV files) by the "Open in… ".
- Export route calculated by mail and "Open in… ".
- Conversion of the calculated route in route "normal" (export to iNavX).
GRIB files :
- Request for fine grids files WRF by email (email, XGate, Iridium Mail) as for files GFS.
