I was never really happy with my old wheel, so decided to dig back into it..
Made a paper protoype (pic below).

This can be used in any sub simulator (SH3,4,5... whatever else)

I must just make it pretty.

Gone is the time consuming methods of computing AOB, position plots..etc
You can calculate the ship speed in about 10-30 seconds realtime. Your scope only has to be up for a quick glimpse - a mere few seconds.
As usual with anything, practice makes perfect

All you need
- Ship ID and Length (Ship manual)
- Ship Field of View in scope
- Time to cross a 1 degree arc (this can be brought down to 0.25 degrees)
- AOB is not critical but AOB and Bearing helps in final speed adjustment of your sub (I'll add a trig graph in the centre)

So with 3 dial rotations, you'll have the ship speed.

Lots of pre-calculated log functions reduced to 2 dials.
