- Overall: 0.58
Hull space for machinery, storage, compartmentation is extremely poor
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily

I just ran my Ger/CS/1905 Design in SpringSharp
I had to make some compromises, but overall I was happy enough with the result. It seemed like I needed to reduce the beam and increase the length to make SpringSharp "happy".
