CM93 v2 charts are vector charts that cover most of the world's oceans and coasts, but they are not officially distributed by C-Map anymore.

In this article, we will show you how to download CM93 v2 2012 charts for OpenCPN using a torrent client. We will also explain what CM93 v2 charts are, how they work with OpenCPN, and what are the advantages and disadvantages of using them.
What are CM93 v2 Charts
CM93 v2 charts are a version of C-Map's CM93 chart database that was released in 1993 and updated until 2012. They are based on the S-57 format, which is an international standard for electronic navigational charts (ENCs). CM93 v2 charts contain vector data, which means that they store information about the shape, position, and attributes of features on the map, such as coastlines, depths, buoys, lights, etc.
Vector charts have some advantages over raster charts, which are images of paper charts. Vector charts can be zoomed in and out without losing resolution, they can be customized with different colors and symbols, they can be overlaid with other data layers, such as weather or AIS, and they can support route planning and collision avoidance features.
However, vector charts also have some drawbacks. They may not be as accurate or up-to-date as official ENCs from hydrographic offices, they may not show all the details or nuances of paper charts, they may have errors or inconsistencies in their data, and they may not be compatible with all chart plotters or software.
