Abstract
The surface geometry of a model yacht hull is generated using the partial differential equation (PDE) method, which enables the shape of the hull to be completely specified using only a small number of parameters while not overlimiting the range of shapes obtainable. This permits a computationally efficient search of the design parameter space for the hull form which optimizes some performance indicator. Here, hulls of low wave resistance are sought subject to certain imposed design constraints. The wave resistance is calculated using a panel method similar to that developed by Dawson. The effects on the hull shape of requiring reductions in approximations to the skin friction and form drags are also considered.
