Nautograf is a viewer for marine vector charts. It is inspired by OpenCPN which is the only nautical chart software that is open source and runs with offline chart data. Nautograf currently only supports chart data from https://www.o-charts.org. Please visit the GitHub repository for more information about acquiring chart data.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
