MarineENC provides Electronic Navigational Charts (ENC, S-63) for OpenCPN, covering ports and coastal waters worldwide. We make it simple to find, purchase, and activate the charts you need for safe navigation — backed by Siitech's chart licensing and delivery infrastructure.

Each chart subscription is valid for one year and can be activated on up to two devices. Charts for U.S. waters are available free of charge through the same activation process.

MarineENC is operated in partnership with Siitech Inc., who handle chart data sourcing, S-63 encryption, and license validation via the Siitech OpenCPN plugin.
