Example: A target is 45º to the right of your bow, and has an AOB of 60º port. You are heading 200º right now. Here's how to set up the wheel:

1.- Move the B ring (True course) until its 200º mark is at the bow of your own ship silhouette in ring A (Matching the 180º mark in the A ring)

2.- Move the Periscope transparent layer to the 45º mark of the A ring. (Here's the reason why it is reversed! To move your scope "right" means in fact moving in the opposite direction the lower part of that wheel, so that the upper shows the target with the correct AOB side)

3.- Last, set the estimated AOB of your target (60º port) in the B ring.

Result: Your target's true course is 105º

, as you can now read in the B ring (True course ring)

Own ship is on course 200 degrees.
Target is on 45 degrees relative bearing.
Target has Port 60 degrees Angle on the bow (AOB)
Set this up on the SACF and see that target course is 105 degrees.

For anyone interested (and yes, I've just necro'd this thread again), I've been working on a solitaire board game version of WWII sub warfare and decided to make a wheel to assist with plotting.

I've redrawn it based on Hitman's version and I'm posting a link to my Dropbox folder where you can grab it. If you find any problems with it (spelling etc.) let me know. It should print to 7.75in dia if you don't scale it. The last page has all the transparencies on one sheet so don't print them separately if you don't want to.
