Hello,
hope i don't bore you :hmm:
This is really simple, but you have to get used to it.
For developing a torpedo solution the absolut bearing (from North or whatever) is not important. This is because all the torpedo (or better the settings) need to know is where the enemy ship is relatively to you own U-boat. So your boat is the
center of everything.

Absoute heading (on the chart): This never changes, altogether there are 360 degrees around a circle, North is 000 or 360 degrees (same here), East is 090 or 90 degrees, South is 180 degrees and West is 270 degrees. Always.
(Hrrm, there may be magnetic deviations, but not in SH3, and even then you have a gyrocompass that does not depend on magnetism.)

If you are heading Northnortheast the absolute course on the map you travel at what course ? Northeast would be the middle from 0 to 90, so 45 degrees. Northnortheast is two parts north and one part East, so you travel at 030 or 30 degrees.

OK, we just said this does not matter setting up a torpedo solution

Standing on your U-boat's conning tower this boat becomes your center of the universe. Your bow always points to zero, or 0, or 000, or 360 degrees. Imagine standing on a ship's deck and you see something to your right. You could yell "something on the right", but unless it is not at 090 degrees this is not very exact.

Were you in a plane you would yell something like "enemy at 3 o'clock high" which would be an enemy plane at 090 degrees and higher relative to your own plane (which's nose again would be 12 o'clock). However we are at sea, and us mariners use the 360 degrees circle, not the 12 o'clock circle, and certainly do not bother
with high or low

So if a watch wants you to tell something like a sighted ship he takes the U-boat as the reference system, and tells you the position of the other ship relatively to your own boat's course - beginning to count at the bow with 0 until the sighted ship appears. This is the course of sight relatively to you ship, or better relatively to your ship's course.
What is confusing here is that they talk about "course". You have to understand that every angle or direction is called a "course" on a ship. If a ship appears to your left your watch will shout "ship at 270 degrees!", and he could as well shout
"ship course 270 degrees!". The enemy ship's own real course does not have anyting to do with it.

Hmm, does that help ?

Greetings,
Catfish
