Good day!
I was hoping that someone with experience in the software can help me convert a design from a fan-made source into a SpringSharp simulation of Alternate Universe Cruisers and Destroyers. For those who are kind enough to participate, you may simulate one of these desired designs. You may adjust the specifications except the dimensions length, beam, and draft. Thank you!
Note: I just wanted to see what they are like in SpringSharp specifications.

What year for laying-down?
Yeah, year can drastically change the tonnage to provide thst shp.
Some assumptions are made here...
1) turreted the main battery given how heavy a quad-130mm probably is. Switching to mount and hoist saves 0.04 HS
2) Went with a transom stern given the speed
3) Also given the speed, I went with a fairly late lay-down date.
4) Can't meet all requested criteria, so zeroed in on hitting the standard displacement.

If I go with a more realistic block coefficient and a slightly lower speed, the design works on paper. The displacement's a little higher than desired but not badly.
However, I don't for a moment thing a quad 130mm can fit on that fine, narrow hull.

Forgot to specify the date, but the said design can take in the years 1935-40.
