This paper describes the analytical foundation for the design of two-dimensional hydrofoils from prescribed pressure or velocity distributions at zero cavitation number. Velocity distributions are given parametrically so that algebraic expressions can be used to define a two-parameter family of velocities on the wetted surface. The method of Levi Civita is adapted to the solution of this inverse problem in nonlinear cavity flow theory. A novel feature of the analysis is the use an eigensolution or ``point-drag`` singularity which may enable one to control the cavity thickness to the extent required by hydrofoil strength requirements.
