This is the emtguf scope attack using the ship from Makmans mission.
Map measured range is 1000m
Mast is 47.82
Length is 239.418m
Pic1 - range/mast height
Pic2 - AOB/Ship Length
As you can see from both pics
Range/mastheight is correct.
AOB/Ship Length is out by 10m
So horizontals need a tweek - this will now be easier with this known ship.
