once you are sure about ship's length ...proceed to determine its mast.create a single mission(totally calm water) with the ship stationary(very close to our boat ,at 0 degrees bearing, showing all of its hull...yes,aob=90)) and take a photo of it through scope ...open the photo with a graphic programm and count the pixels of its length and the pixels of its mast from waterline .(this is necessery to be done so becuase the .sims files for each ship determines how much deep the ship will 'sit' in water)
then true mast = (true length x mast's pixels)/length's pixels

after all these you will have a ship with correct length and mast values and you will be ready to test your rings .just have in mind that there are some tiny inaccuracies at the rings itselfs .

Thought anyone?
