Chart Manual Correction

[Askoldasha]

Dear Sirs, please explain, how can I do manual correction on CM93 charts?
Add new objects, delete them, add depths, edit, etc.
I can't find this option on Manual.
Thank you

You can't edit the CM93 charts.

What you can do, it's feasibility depends on the amount and nature of changes you need to do, is to use the OpenCPN's draw plugin or a GPX layer for your corrections.

Or produce your custom raster charts in KAP format (Simple free tools are available for that, besides the obviously needed bitmap editor of your choice).

Or produce your custom S57 vector charts, if you have some tools to edit them.
