The report consists of three parts. Part I investigates the mathematical theory of variational calculus for the general problem of optimum hydromechanical shapes in a wide class of free surface flows. In Part II the general theory is applied to determine the optimum shape of a two-dimensional planing surface that produces the maximum lift. In Part III the optimum shape of a symmetric two-dimensional strut is determined so that the drag of this strut in infinite cavity flow is a minimum. (Author)
