54.99€ iOS only (+ 37.99€ optional subscription for 38 weather and oceanic models)
Weather4D Routing and Navigation is the most complete version of the Weather4D application suite. In addition to previous versions dedicated solely to weather and routing, this version also includes access to marine cartography and the datalink with on-board instrumentation. In doing so, it becomes an ultra-complete application, either for the preparation of your navigation, on the way or even until the review of the recorded tracks once your destination is reached.
List of major features :
- Weather and routing: functions identical to the Weather4D Routing app with the possibility to compare several weather models (and thus several routings) on a split screen
- Cartography: access to various raster-type map catalogues exclusively, issued by the major international hydrographic services (this access is obtained by subscription to Geogarage service). Possibility to display several types of charts in split screen, with different zoom levels (for example: wide view of the weather situation, close view of the nautical chart)
- link with instruments: display of NMEA data from a Wifi transmitter, with the possibility of controlling the autopilot from the navigation data. Fully customizable instrument panel. AIS support
- Native support for Iridium GO!™ for direct download of all GRIB weather models, and automatic queries via SailDocs of the GFS model with all other satellite phones.
The application is full of ergonomic tricks: moving the map under a cursor for ultra-precise waypoint positioning, ease of correcting a route (inserting, deleting waypoints), view of the boat on the map with its forward vector and apparent wind, repetition on the Apple Watch, etc... And several improvements are already announced: automatic filling of a logbook in particular!
iOS 5.49 € (+ in-app purchase : AIS Live, Weather, Maps)
Android Free (+in-app purchase iNAVX PRO 2.5$/month - 29.99$ all navigation options, maps)
One of the most complete marine navigation application
iNavX ™ supports the use of waypoints and routes, recording of traces, the measurement of distances and bearings. It displays navigation data in a dynamic instruments banner on top of the map. It enables the animated display of GRIB weather files directly on maps, as well as viewing AIS targets if you have an AIS receiver.
iNavX ™ interprets all NMEA data from a WiFi transmitter and displays it in the instruments banner on the map view, or in a dedicated view. The application is able to control an autopilot from its navigation data.
It exports and imports tracks, waypoints and routes, either for backup, or to exchange with another application. This is an essential function if you want to optimize a route, e.g with Weather 4D Pro routing function.
iNavX allows the use of many formats of maps from different publishers, including popular Navionics vector charts, to be bought exclusively through X-Traverse (see our tutorial).
The cost is very reasonable: for example Navionics 46XG for iPad covers Western Europe, the English Channel and half of the Mediterranean for just $70, or barely more than €50. Same iNavX licence can be used on iPhone and iPad. However the maps are differentiated: the Navionics map for iPhone cannot be used on iPad and vice versa.
Beware: the Navionics maps used by iNavX are not re-usable in the Navionics Boating app, and vice versa.
iNavX now has a multimedia iBook tutorial in english by Francis Fustier
SailGrib WR (Weather Routing) is a weather routing and navigation application that includes all the functions of SailGrib (see Sailgrib in marine weather applications).
Marine charts are to be purchased in-app (Navionics charts or SHOM/UKHO charts). Note that Navionics charts are free if you have already purchased them in Navionics Boating )
For routing, the user can specify many parameters including :
wind force multiplier coefficient.
theoretical route, date and time of departure
speed polar: 140 polar for the most common sailboats. You can also add the one of your sailboat.
polar efficiency upwind and downwind for different wind forces
wind limit values upwind and downwind
minimum upwind angle for comfort during cruising
loss of efficiency during the night (safety reef, no spinnaker,...)
mixed motor and sail routing
currents: only the paid version allows you to download (free of charge) the tidal current forecasts for the Atlantic coast.
The free version is limited to 48 hours of forecasting and routing of 50 Nautical.
The most popular and certainly the most user-friendly application for marine navigation. It can be downloaded
for free, and charts need to be bought in-app.
Application includes interesting features: possibility to superimpose a satellite map view, tides, many information about points of interest (harbor office phone number, local services, shops, etc.) and also allows the sharing of information between users (community sharing).
Coming with very basic navigation functions at the start, the app must be supplemented by various modules if you want to navigate :
-the NavModule (€4.49 - iOS only) is absolutely essential: it enables the creation and following of routes with GoTo function.
-the Autorouting module (€4.49 - iOS only) is more of a gadget, and allows to automatically draw a route between two points while avoiding obstacles.
-Personal chart (€4.49) allows you to customize the display of the items on the map (depth lines, colors, fishing areas, etc.)
- Navionics+ module provides access to the SonarCharts function which complete bathymetric data from user surveys. In addition, it allows permanent updates of the charts for a year. It comes at high price : an annual subscription of €49.99
However this application is limited because it cannot exchange data with the outside: no possibility to import weather data files, no AIS display, no import/export of routes.
iSailor is a very ergonomic application with good quality vector maps. Transas TX-97 maps cover all the globe, including the water bodies and waterways of Europe and the USA, cut in many cells at an average price of €22.
App includes most features useful for navigation: import/export of waypoints, routes and tracks, NMEA interface for display of AIS targets, optional NMEA link for GPS and external compass, distance and bearing calculation tools, etc. A nice side “drawer” on the display provides access to settings, navigation data, waypoints and routes management.
The application is free, and you can buy charts directly from the application, as well as options which are at very reasonable prices: € 9 for AIS data and €5 for NMEA GPS data.
The application presents a great value despite the new options that increase the price. There are still some imperfections in the display of information on the map according to the zoom levels, but its ergonomics is excellent and it is easy use.
Edited by the American company Jeppesen, Plan2Nav is based on C-Map 4D Max vector charts , bought in 2007 by Jeppesen. A direct competitor to Navionics, this mapping with global coverage is particularly aesthetic. It enables a perspective view in the axis of the vessel, in the same manner as MaxSeaTimeZero. You can also switch to a satellite or Google Maps view if you want.
Several functions are featured in this application:
-real-time display of currents
-display of current and forecasted weather data
-base of information provided
However, ergonomics is quite average, manipulation to create waypoints and routes are confusing and no help is provided in the app. No external connection is possible other than with a specific (non documented) chartplotter, nor any import/export of route or GRIB files : this limits the interest of this application.
Charts can be purchased in-app. Relatively large areas are at an average price of € 40,00.
free iOS (+ in-app purchase : AIS module, Radar module, maps)
Developed by France's prominent PC navigation software vendor, TZ iBoat has excellent aesthetics and ergonomics. It allows you to merge aerial views and nautical charts, with the possibility of displaying them with 3D relief superimposition.
However, it remains limited compared to major applications such as Weather4D Routing & Navigation, iNavX or iSailor: NMEA support limited to AIS (optional 9.99 €), data import/export only by iTunes, very limited weather forecasts. The radar module for Furuno DRS4W Radar is available as an option (€49.99).
TZ iBoat uses raster maps from MaxSea's MapMedia MM3D catalogue and C-MAP vector maps. Some data are only accessible with an Internet connection, which limits their interest (terrestrial imagery, weather). The maps can be purchased directly from the application (50.99 € the first year then 25.49 €/year for raster, from 66.99 € for C-Map first year, 50% the following years). Warning: raster cards are very large, check that you have enough storage memory in your device.
NavLink UK is the first application to offer ENC S-57 charts of the UKHO, the hydrographic service of the British Admiralty, on iPhone and iPad. A NavLink US version is also published on the American AppStore with vector maps from NOAA. Unlike many of its competitors, it is not free, but for €26 you have all maps covering the United Kingdom, the Ireland and the Channel Islands. Recently the geographical coverage has been extended to other regions.
In addition to the classic functions of management of waypoints, routes and tracks, NavLink allows the display of AIS targets and receipt of an external GPS by connecting in Wifi to a NMEA router.
NavLink stands out especially by an augmented reality map display function when using the camera integrated into the Apple device. The ship route appears in real perspective, surrounded by the coast, marks, and AIS targets. It is innovative and quite stunning. It remains to see if it is useful in situation. Negative point: the display of information on the maps is not clear and the color choice is not appealing.
free - iOS
Marine mapping application for iPad and iPhone by the English Publisher Imray. It uses the famous "Blueback" scanned maps. Unfortunately their use is quite difficult: the passage from one card to the other of various scales is inconvenient, and maps are insufficiently detailed in some areas.
In addition to the usual basic duties (waypoints, routes), this application includes some interesting features:
-tides (of the day - for predictions, you need to buy Tides Planner)
-NMEA interface for display of AIS targets.
The application is free but incorporates only a general map of the English channel. Other charts can be purchased on the integrated "ChartStore". The cost of maps is around €45. SHOM cards are now available for the French coast. This application suffers from particularly bad ergonomics and learning takes time.
1.99€ - iOS
Real Swiss Army knife of GPS, this application covers all uses of GPS for land, sea* or air navigation, with a particularly neat interface.
*Warning : only U.S. charts are currently available for navigation.
