About OpenCPN: Chartplotter & GPS Navigation Software.

OpenCPN is a free software (GPLv2) project to create a concise chart plotter and navigation software, for use underway or as a planning tool. OpenCPN is developed by a team of active sailors using real world conditions for program testing and refinement.

The most recent stable version can be downloaded from opencpn.org/ocpn/download

You will be able to find digital charts for all areas of the world, including navigational charts, pilot charts, tide tables and have access to many other resorces once you get started with your OpenCPN app.

To get the most from this software, take a look thru the OpenCPN Users Manual. If you get stuck, there is lots of very useful advice and tips on the Cruisers forum website.
