An anachronistic King Edward VII design

I have a pencil drawing of an anchronistic King Edward VII class battleship that I probably drew in the latter 1980's:

It is a rather bad photograph, but you can get the general idea of what I was doing. The Springsharp design worked out amazingly well. I suppose it was because of the later engine date that made the weight lighter. This is the Springsharp 3.0b1 Beta report:
