MarkOne is a web application that provides boat data on mobile devices. It is a research and development project at the University of Applied Sciences Konstanz, known as HTWG. The project is being developed by students of the Applied Computer Science track and is led by Prof. Dr. Marko Boger. Our goal is to develop an App using advanced web technologies with one software stack for all relevant devices. It builds upon the Signal-K protocol and server, which translates the NMEA data on a boat's data bus to a format usable in web browsers. For optimal usage, your boat should be equipped with a Raspberry Pi, connected to the boat's NMEA cable.   But it is also usable in stand-alone mode, using the GPS data of your device, or in demo or simulation mode if you just want to explore its capabilities.  The project is provided as open-source and free of charge - but also without warranties - it is an ongoing research project, not a commercial product.

MarkOne - Key Features

The MarkOne Sailing App focuses on these features:


MarkOne gives you access to all data relevant to your sailing trip. Information that is traditionally provided on a multitude of displays or meters is now available in one place.
