OpenCPN is free software distributed under the GPLv2 license. A program has been created for the organization of maritime navigation of ships of various types and sizes. The program was created by a group of seafarers who immediately tested it in real conditions, improving and eliminating the shortcomings found. In addition to navigation, it is possible to pre-plan routes.

The program makes it possible to track the current position of the vessel, its speed and direction of movement, taking into account the data of navigation charts and forecasts of tides and currents. An interesting feature is the reception of information from other vessels about their location and course on the radio line. The GPS global positioning system is used for the navigation itself, and in case of its absence the program is used as a planning tool. Cards for OpenCPN are free and available for download on the official website.

OpenCPN offers real-time tracking of a vessel's position, speed, and direction, enhancing maritime navigation and route planning abilities.

While the vessel is in motion, you can select a new map and display it with the required resolution and detail. To use an external autopilot, you must enter the route and waypoints. The documentation included in the program includes a lot of useful information.

I recently started using OpenCPN software for navigation and chart plotting. I must say that I'm very pleased with how user-friendly the software is. The charts are highly detailed and easy to read. I also like that the software automatically updates my charts, which makes staying up to date with the latest changes much easier. I also appreciate the customer service that is available with the software. I've found the customer service reps to be very helpful and knowledgeable. One of the great features of OpenCPN is the ability to customize the software to your own preferences. I like that I can add my own custom waypoints and routes, and that the software allows me to mark my favorite spots. Overall, I'm very impressed with the features and functionality that OpenCPN has to offer.

OpenCPN is a great software for navigation and chart plotting. I've been using it for a few months now and I'm very impressed with the features and stability. The user interface is very user friendly, with all the controls nicely laid out and easy to understand. The chart plotting and route planning facilities are excellent and very detailed. The auto-follow feature is particularly useful, and the AIS integration is very helpful. I've found the software to be very stable, with no crashes or unexpected behaviour. The support is also very responsive and helpful. Overall, I'm very happy with OpenCPN.
