Learning to use a maneuvering board can be pretty hairy at first. Just try to do exactly as it says in example 25. When I was learning to do that myself I did not understand a thing about what I was doing at first. Now I'm very slowly starting to understand something about why and how it works.

Try to forget about the position of your U-boat or the position of the target. Print a maneuvering board and draw the picture on paper to make sure you are not confused by the sight of your U-boat on SH3's Navigation Map. Think about movement instead of positions. It's like two cars driving towards each other. Positions are old history, to avoid a collision you want know the speeds and directions of your car and the other car. It's the same with U-boats and target ships, just the other way around: you want to find a collision course in order to get close enough for the torpedoing.
