[4S/yim224] A Statistical Re-analysis of Resistance and Propulsion Data

According to full-scale test data result was described in previous publication (An Approximate power prediction method, ISP Vol. 29, 1982), a power prediction method was presented.
This obtained formulae was found insuifficient accuracy for some classes of ship, especially for high-speed craft (Froude Number above 0.5).
The regression analysis was based on the result of test on 334 model, in order to create more accurate power prediction/calculation.
In fact, the formulae is still in used until present day.
