What are CM93 v2 Charts?
CM93 v2 charts are a collection of vector-based nautical charts that cover most of the world's oceans and coastal areas. They are derived from the C-Map 93 format, which is a proprietary format developed by Jeppesen Marine, a subsidiary of C-Map. C-Map 93 charts are widely used by commercial and recreational mariners for navigation and planning purposes. They contain various layers of information, such as depth contours, buoys, lights, landmarks, ports, tides, currents, and more.

They are distributed through peer-to-peer networks, torrent sites, forums, and other online platforms.
