Ok,
I took time to read your post, and the explanation to use the wheel is very detailed and clear for noobs (like me).
but there is still one thing that eludes me.
Call me stupid, but how do you know or calculate the target's course ?
It's very easy to determine the target's bearing, but to be able to tell the exact course, is only possible if you shadow the convoy or merchant and follow its course yourself.
Is there another way ? that would be superb. As of now I can't think of another way of getting the target course correctly.
Thanks for taking your time to put it all out so clearly.
sincerely
