GB/CB/1914: my first Springsharp 3.0 3rd Beta design

I finally downloaded the third Springsharp 3.0 3rd Beta version. I decided to try the large, fast battlecruiser with 12in armour: the GB/CB/1914. This is a design that is more archaic looking than the Hood, but a stronger and more heavily armed ship:
