j'am french and j don't know very well the english language , but just enough to said , that is important we can move the chart , because we can't see the ships coming from the starboard side .
To hide/show the chart ,it's not a goog idea , if you are a mariner , you must know the priority for electronique helps to naviguate . chart , radar etc......
Please ask to change the position , it is more realistic
sorry again for my english writing
