Sailserver gets information about your boat’s position, course and speed from its built-in GPS. Your sailing trip is logged continuously on your Sailserver and when there is Internet coverage, the logbook is automatically uploaded to sailserver.com where you can access it. If you connect Sailserver to the other instruments on your boat during the installation process, then it will also retrieve logbook data from these sources as well. This might include details on fuel consumption, for example. The server retrieves place names and weather data itself and records this information in the logbook automatically.
