What's the advantage of a shipyard 4 as opposed to a shipyard 1? Obviously the cargo capacity and docking ports and such, but is there any special differences like building multiple ships simultaneously?
A SY4 can build bigger ships than a SY1. From what I have heard, the length of the SY is the maximum length of the biggest ship it can build. But a SY4 can build up to the biggest ships no matter what the size is. If I am wrong, please post here so I will know myself.
