"Program Descrlptlon, Equations, Variables
This program predicts effective horsepower (EHP) requirements for planing craft over a selected range of speeds and longitudinal center of gravity (LCG) locations. It essentially automates the "Savitsky short form" procedure (Ref.1) where all forces of propulsion, lift, drag and weight are assumed to act through the center of gravity. This provides an excellent tool for preliminary design, when variables such as propeller shaft angle and position are not yet decided … "
