The Desktop Configuration Wizard that will guide you while configuring the program for a new regatta leg. Use menu option File > Config Wizard. The wizard will help you choose a chart file, a polars database, specify the first mark (i.e. first destination), the leg name, boat name etc. In the end you will save that configuration to a new desktop file. Desktops are text files with extension .nav.
Every time you start the program, load that desktop file to retrieve the configuration you created for the regatta leg. To load an existing desktop use menu option File > Open Desktop.
If you are new to the program, try the sample desktop vrtool.nav. This will open a chart with a couple routes, tracks and marks. You can add our own marks, design routes and tracks, add great circle routes or use weather routing to generate tracks and isochrones. All these objects will be saved to the desktop file.
