Routing & Navigation
The Boating Community holistic solution
Weather4D Routing & Navigation is an iPhone / iPad marine application which integrates weather forecasting, routing calculations and navigation. It allows accessing to nautical charts derived from original material provided by the International Hydrographic services of 17 countries. Your boating experience is transformed from navigation preparation all the way to reviewing recorded tracks after reaching your destination.
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.
Set the screen to night mode after sunset to better see what’s happening outside during your watch.
Set alarms to alert about low precision GPS signal, 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… The splitted screens can display charts at different scales.
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 and thus get a holistic view of all the parameters affecting routing calculations.
Restart a routing calculation at anytime from the actual boat position.
