My latest attempt at a Super Fast Battlecruiser using Springsharp

I took another shot a seeing if I could make the Super Fast Battlecruiser work in Springsharp. I wrote about this last October, and had my 1970's era drawing. I expended considerable effort to make the design have adequate seakeeping ability. The ship had to get wider, longer, and deeper. Even then, the best I could do was 39 knots. It at least captures the intent, although at a greater cost.
