The simulation mode is the easiest way to learn how to use The Fast Track before using it at the sea.
Enable simulation mode through Preferences -> Simulation Mode
You can select the coordinates where you want to start the simulated sailing, in decimal degrees.
Simulation mode provides buttons for Speed and Heading Simulation.
When this mode is started, boat is moved from your gps location to your simulation preferred coordinates and inversely when disabling simulation mode. Therefore after every mode change you will be asked to delete the sailing track since it is mixing real with simulation information.
All the functionality available in normal mode is also available in simulation mode.
Remember, simulation mode is the best way to test and train the app usage.
