OpenCPN (Open Chart Plotter Navigator) is a free software maritime chart plotter and navigation software for use underway or as a planning tool. Developed by a team of active sailors and tested in real world conditions, it has multiple supported chart formats and a variety of data inputs.[3][4]

By using satellite navigation and other NMEA 0183 data feeds, OpenCPN determines a ship's own position and status from sensors such as AIS receivers to automatically plot and track the positions of ships in the neighborhood.[5]

In 2017 Norwegian ENC charts were available for OpenCPN.[6]
