Project's goals

QtVlm is a routing software for virtual and real sailing boats. QtVlm is used in two modes:

  • Virtual Racing designed to manage and pilot virtual boats from Virtual loup de mer VLM virtual races.
  • Real Boats connected (or not) to a GPS device.

QtVlm uses boat polar diagrams and grib weather files, and includes

  • Routing module (isochrons method),
  • Route module respectively allowing route optimization and waypoints management.

Main Functions

  • qtVlm is a Grib Viewer (qtVlm is derived from zyGrib) and a routing software
  • Download and load grib files from VLM (5 days), zyGrib (1 to 8 days) or SailDocs (1 to 16 days). QtVlm accepts many other grib sources.
  • Display meteo faxes
  • Two Modes: Virtual Race Mode: Configure VLM player account and boats, or Real Boat Management Mode: Define a real boat connected or not to a GPS
  • Send GPS trace to a port, for other applications (Google Earth, routing software, ...)
  • Define routes (succession of waypoints) with many options (route from boat or from a fix point, starting time, navigation mode, coast collision, etc)
  • Calculate where you will be after a given time in several mode (fix TWA, fix heading, etc)
  • Move POIs and WPs (shift-click)
  • Create a routing and then convert it to a Route.
  • Display or not a Compass and the boat's polar on the map, with various options
  • Display/Hide various object on the map
  • Save 4 map positions/zooms via ctrl+F9/F12 et restore them via F9/12
  • and a lot more....


In case you use qtVlm to manage VLM virtual races, you can:

  • Visualize all your boats on the map
  • Send orders to the selected boat
  • Manage auto pilot VLM Autopilot management
  • Define your VLM current WP with a simple click My WP
  • QtVlm will import and display automatically gates and race's WPs from VLM
  • Etc...


  • In order to preserve VLM servers, the refresh of the boat's position is not automatic, you need to press <VLM sync> or <F5> to update your VLM's position.

Quick start up

  • First install the program
  • If you want to use qtVlm with VLM (Virtual Loop du Mer) Virtual Racing, you need to:
  • In the toolbar select the boat you want to send order to (14) on qtVlm toolbar
  • You then need to load a Grib file from the Grib menu. To start with something select VLM grib. After download the grib is displayed. In the toolbar you can click on the arrows (7) and (9) on qtVlm toolbar to change the date/time displayed.
  • Create a route with menu Routes>Create a route (more help)
  • Create 2 waypoints (POIs) by right-clicking somewhere on the map, call them POI_1 and POI_2 for instance. In the dialog assign them to the route you just created. (more help)
  • By default intermediary POIs are not displayed. You can change this behavior in the route's options.
  • The route takes WPs in alphabetical order, so it will first go from you boat to POI_1 and then from POI_1 to POI_2. If the option "Detect Coast Collision" is activated, the route will change color if crossing coasts.
  • You can then for instance move the last POI with <shift-click> and see the date of arrival (ETA) being recalculated.
  • To start, setup the boat in VBVMG mode (VBVMG button on the boat's panel more help) to the first WP (POI_1) (Right click on it and select "mark->WP VLM")
  • This intermediary POI can be moved with <shift-click/drag> (more help).
  • You can also automatically optimize the POI position on the route (right-click, menu "Optimize").
  • QtVlm also has a routing module, available in the menu 'Routing->Create a routing' (more help)
