OpenCPN 4.4.0

Welcome! This is the Documentation for the OpenCPN 4.4.0 stable release. It is very easy and intuitive to get started with OpenCPN. The different menus, including the clever context-sensitive right-click menu, make it likely that you will find what you need. The program contains a lot of options to fit users with special demands and hardware.

HELP, FAQ & OpenCPN User Manual

The most frequently asked questions by new users, seen in the OpenCPN Forum, are, in most cases, already answered in the OpenCPN USER MANUAL. If you are going to use this program for actual navigation, you need to read through this document to fully understand the scope of the program, as well as all the details.

If you have difficulties finding a particular subject, please use your browser's built-in search ability, often called just “Find”. This works best using the stable release which is all on one web page.

In the Program “OpenCPN” Press and then the Help Tab to access the built-in version of this document. The installed documentation will open in your default browser. This is the first place to go for help, read the documentation please. To download a current snapshot of this wiki as one huge web page, Click here for fullindex (only works if you are online). Note that the details of downloading a single file html formatted properly have not been worked out yet.

To help you get started:

  • Links in italic are internal to this document. Placing your cursor over a link will cause the link to be underlined.
  • External links may be Bold, Underlined, or in the “http:/\…” format and need an Internet connection.
  • Marks and Waypoints may have somewhat different definitions; however, in this document they generally mean the same thing.
