Not to criticise your wanting to use the technique; there's nothing wrong with trying a new method. But, many mods have either added or altered ships, and this makes keeping, an up to date, listing of aspect ratios difficult. There is also some uncertainty as to how faithfully the images of the ships are rendered in the game.

You might be better off using a combination of plotting (and trig), and 'seaman's eye' to determine AoB or ship's course. This was how actual USN captains did it.
