Weather4D Routing & Navigation integrates weather forecasting, routing calculations, navigation with digitized raster charts, instruments and data sharing to maximize your boating experience.

See SOG, COG, VMC, HDG, TWS, AWS, ETAs, ETWs, AIS data and more in real time along with weather and routing information with a wifi connection to a transponder.

Store your charts on your device for offshore/offline navigations.

Set the screen to night mode after sunset to better see what’s happening outside during your watch.

Set alarms to alert about excessive XTE, course deviations, surrounding boats, excessive wind speed and low depth.

Take advantage of the iPad/iPhone built in compass, pressure and acceleration sensors.

Connect bluetooth devices like wireless anemometers and wind vanes.

Share AIS and boat sensors data like wind, current, pressure, air and sea temperature within the Weather4D users community.

Activate Man Overboard safety feature to estimate drift and thus rescue location based on current and wind.

View combined weather data displayed in 3D HD layers animated automatically or manually by sliding a finger on the screen.

Use GFS model to get started. In addition, over 35 weather and oceanographic models are available with a yearly subscription (in-app purchase).

Create your own geographical zones, select the models you need and download only the characteristics that matter to you: data type, resolution, periodicity, file size, etc. GRIB files can be downloaded anywhere through a regular or satellite internet connection.

Split the screen (iPad only) to combine and/or compare: navigation and weather, weather and waves or currents, two weather models…

Routing calculation optimizes for safety, comfort and performance when sailing, motoring, or mixing the two.

Create a route and calculate its associated routings in function of departure dates/times, forecasts (weather, wave and current), minimum sailing speed, motoring speed, boat polar, maximum wind and minimum distance to the coast.

Visualize sail configurations based on your routings and your own set of sails.

Save waypoints, locations, simulate routes, combine them with GRIB forecast models.

Restart a routing calculation at anytime from the actual boat position.

A fantastic progam

I used this program for a 1800 miles boat transfer (with the SHOM subscription and the weather model subscription). I found it one of the best programs in absolute I have ever seen. It is extremely solid, extremely well thought, a real pleasure to use in all weather conditions. Well worth the money and +.


Great customer service

I just purchased the Routing and Navigation App on the recommendation of a friend. Although it looks like there is a steep learning curve, there is a free book on iTunes and I’ve gotten great help with quick and detailed responses via email from their support team. I’m looking forward to using the app for racing.

Nice app

It takes a little time to get used to the interface and all the capabilities of this app, but once you grab the feel of things it is very complete and visually beautiful. Customer support is fast and effective.
