Novice stupidity...

I did try to play Dangerous waters, ... but a bit hard.
Now trying to play 688(i). I asked a question about how to plot a course, but no one answered. Therefore I will ask it here because on this place are many more readers!

This was my question:

I want to play 688(I) / single missions / Rebel Yell. My order is now to sail to the sea of Okhotsk.

On the map I see my boat, but not exactly where I am. I don't see names anywhere and I can't find how to sail to the sea of Okhotsk because I can't zoom out either.
How to plot my course?

A little help for a novice?

By the way:
If I start Dangerous Waters, then I also see no possibility to plot a course.....

I understand that I don't understand something well...
