Thanks alot! I've made a simple tool from CaptainKrunch's 1943 AoB calculator above, also. It took me a while to figure it out but I used your examples. Awesome.

For those of you who are using this really cool tool this is what I gather from it:

I set my bearing from due north by rotating the 0'mark on disc B to the appropriate heading on disc A. Then I do the same for the target's bearing from due north by rotating the 0'mark on disc C to the appropriate heading on disc A, also. Then I rotate the 'periscope disc' across disc B, which should match my sub's periscope heading 'in-game': this is the target's bearing RELATIVE to my submarine's heading. AoB = 180 degrees, or directly opposite, from the periscope caret.

Example:

My sub is heading due East, 90 degrees.
Target is heading due East also, 90 degrees.
Relative bearing ('periscope bearing') is 0 degrees.
AoB = 180 degrees.
Which makes sense because my boat's trailing directing behind his ship.

Example:

My sub is heading due East, 90 degrees.
Target is heading due South, 180 degrees.
Relative bearing ('periscope bearing') is Southeast, 45 degrees.
AoB = 135 degrees Starboardside.

I started with some simple example like these because they're easy to visualize and check mentally, so I could be sure of my AoB results from more complex examples.

Thanksforallyourhelp mates!
