Thanks for your tips and ideas.
I know I can add polygons and line features (paths) in RM, but I cannot see how this could easily be used for making and adding this kind of objects to my charts. Each object is more or less complex, with several non-connecting parts. At least I cannot see how I can make them in RM, and save them. Maybe I can make the objects in ArcGIS or similar, and save them as a shape. But would RM be able to handle multipart shapes?
GPSMapedit is a wonderful program, and I have used it a lot when I was preparing Garmin maps via the cGPSMapper. But since I use Lowrance HDS now, I only intend to use RM and export directly to Navico Map Creator. So using external tools does not seem to be a good idea. Or would it be possible to export the data from RM, process it in GPSMapedit, and then import it back to RM without losing anything?
Still, best would be a dedicated function within RM for adding predefined (or user defined) icons for rocks or other objects.
