Let's address the central issue: There is no legitimate, free, public download for CM93 v2 charts.
C-Map is a commercial company. CM93 v2 is a proprietary, copyrighted product, originally sold on CD-ROM or CF cards for hundreds (or thousands) of dollars. Any website, torrent, or forum offering a "CM93 v2 charts download link" is distributing pirated software. This is illegal and carries risks:
Use the SAS.Planet plugin for OpenCPN or simply use Google Earth (offline cache). Combine satellite imagery with official free charts for a powerful visual reference.
The days of seeking a CM93 v2 charts download are numbered. While nostalgia and the desire for a single, offline file are understandable, the risks of malware, legal consequences, and—most critically—outdated navigation data make it a fool’s errand.
Embrace modern, legal alternatives. Free ENC charts from hydrographic offices, coupled with software like OpenCPN, provide the same (or better) functionality without breaking the law or endangering your vessel.
Sail smart, chart legally, and keep your data current.

The CM93 v2 charts (C-MAP 93 edition 2) are a widely used set of global vector charts in the maritime community, particularly among users of open-source navigation software like OpenCPN. Technical Overview
CM93 v2 charts are based on the S-57 standard but use a proprietary format developed by C-MAP. Unlike newer versions (like v3), the v2 format is "unencrypted," meaning it does not require a hardware dongle or digital license key to view once you have the files. This accessibility has made them a staple for cruisers and hobbyists using OpenCPN. How to Use CM93 v2 Charts
To utilize these charts for navigation, follow these standard steps:
Software Installation: Install a compatible chart plotter. OpenCPN is the most popular choice for Windows, Mac, and Linux.
Chart Organization: Place the CM93 folder (usually containing numerous subfolders labeled 030, 060, etc.) in a dedicated directory on your computer. Loading the Charts: Open your navigation software. Navigate to Options/Settings > Charts > Chart Files. Click Add Directory and select the main CM93 v2 folder.
Select Update Control Database or "Scan Charts" to index the data. Important Considerations
Data Currency: CM93 v2 charts are outdated. C-MAP ceased official updates for the v2 format years ago in favor of newer, encrypted versions. They should be used for situational awareness and planning, but not as your primary means of navigation in restricted waters where recent hydrographic changes (like shifted sandbars or new buoys) are critical.
Legal Status: While the software to read them is free, the chart data itself was originally a commercial product. Most copies found online are distributed via community forums or peer-to-peer sites rather than official storefronts.
Modern Alternatives: For up-to-date official data, many sailors now use o-charts, which provides affordable, licensed S-57/S-63 charts specifically for OpenCPN users.
Overview
The CM93 V2 charts are a set of electronic navigational charts (ENCs) that cover various regions, providing detailed information on water depths, navigation marks, and other essential data for safe sailing. The charts are designed to be used with compatible navigation software or devices.
