Already might well-known story, I want to know for the ship-production thing. If I will need one BB, I will product BB using some dockyards. Then I will get some vessel for year, ex. like 0.75. Then 16 months later I will get one vessel and could use one, right? Or until 2 years later I will get 1 vessel plus 0.5 vessel(?) and could use just one vessel?
If I understand you correctly, you won't have to wait until the line completes twice - you'll get the battleship as soon as that unit is completed. If you put more dockyards on it, you'll get the unit faster, but you won't have to wait until the cycle completes multiple times to get the ship you ordered.
