Mathematically rigorous tools for the definition of thickness and camber distributions have been developed which simplify the generation of lifting surface geometry and ensure smooth variation of profile curvature. The developed tools can produce almost identical geometries to many standard profiles including the classical NACA series. To assist in development, section profiles are formulated from parametric equations that encapsulate the key flow parameters such as the leading-edge radius, and the locations of maximum thickness and camber. This enables context dependent optimisation starting from a well-established base profile. Use of these tools is demonstrated by development of a complex hydrofoil geometry to study cavitation in tip leakage flow. The ratio of lift coefficient to minimum pressure coefficient is used to determine cavitation performance. The hydrofoil geometry is based on a NACA 66-012 (mod) profile, which has been improved to achieve good cavitation performance over a wider range of incidence.
