What is Power Prediction for Ship Design about?

This document outlines a method for performing a preliminary prediction of power requirements for ship design. It involves estimating ship resistance for a range of speeds using resistance data and calculating the effective power. The trial speed is determined where engine power is 85% of maximum. Iterations are done to determine the optimum propeller rpm and diameter that satisfy the trial conditions. Finally, an engine is selected based on the power per cylinder required.
