The GB/CS/1915 works extremely well in Springsharp 3.0b1 Beta

I am really pleased with how well that the GB/CS/1915 works in Springsharp 3.0b1 Beta. My friend Cliff's original concept from 1971 is vindicated by what I am seeing. This is a photo of one of the ships at sea:

This photo gives a very good idea of the original sketch design, as I tried very hard to give an accurate presentation. One of the ships has a length of 405ft, a speed of 32 knots, and an armament of 4-6in/50 QF guns with 4-21in TT. This is the Springsharp report:
