Hi John

On your ECDIS your charts have to be issued by or on the authority of a Government, authorized Hydrographic Office or other relevant government institutions are official and may be used to fulfill carriage requirements, provided they are kept up to date.

All other charts are by definition not official and are often referred to as private charts. These charts are not accepted as the basis for navigation under the SOLAS convention.
