Abstract: Regression analysis is used to express the wake fraction, thrust deduction, hull efficiency and relative rotative efficiency in terms of the varied hull parameters. The standard errors of the regression equations are small, and the agreement with test results is better than any of the previously suggested expressions. The effect of variation in the propeller diameter is accounted for by correction factors in the form of analytical equations.
