Questions about the Four bearings method, etc.

How do you find the "red line" in the Four bearings method and what are the procedures?

It seems that in every video that illustrates the Four Bearings method there's always a point in the video where it says "read Kuikeug's notes for this "red line" and I can't find anything on it, there is one pdf called Four bearings method v2 which tries to explain it but I just can't understand it.

Also are there any good videos out there shows how to intercept a ship or convoy that has appeared through radio or however those little boxed things on the map appear?

For the second question, it can be done with the attack disc called Angriffsscheibe. A fully professional manual is available in English somewhere on this forum.
About the first question, I will try to describe it later

Please take your time.

And I've found a nice tutorial about intercepting contacted ships in the Newbie Guide.

To create a red line, having first three lines, you first plot completely random course line. It intersects all three lines and extends forward, where you expect your target in the future. This course line will be our base to determine the first point which the red line will be going through. Take a compass and along this hypothetical course measure the distance between first and second line. Let course intersection with the second line be p1. Move this length now from p1 towards the third line. Mark m1. Now at that mark draw the parallel to first line intersecting the third line at m2. Now take the compass and measure the distance from p1 to m2. Move the circle so so it begins at m2 now. Mark m3 at the arrow end. It is the first point of a red line. For the other random course line do the same to have the second point for red line.

Maybe this is a help.

A new hunting tutorial.
