My power estimates for the Ger/CB/1911 were quite good

The methods that I had used in the early 1970's to estimate the power required for the Ger/CB/1911 were quite good. For a displacement of about 35,000 tons, I had estimated 140,000 SHP to achieve a speed of 30 knots. The ship, as designed, however, had a great deal of excess capacity, so to speak, so to use what was there, I greatly increased the range and cruising speed, while reducing the displacement. The result is that the standard displacement is only 27,492 tons, which is not unreasonable. The ship, as designed, had very light weight machinery, which is part of the explanation for why the tonnage was underutilized. This is the Springsharp report:
