As Petter said, these charts - same as
Navionics or
Garmin - come in a proprietary encrypted format and would require a specific plug-in for OCPN. Such as for NV-charts or BSB3 raster charts.
No problem for OCPN, just ask as a user of Jeppesen if they want to provide one or set up a joint effort to implement it. We are listening.
