The optimisation of aerodynamic lift distribution for a heeled yacht in a wind gradient

Abstract

A mathematical model has been developed to predict the distribution of lift over the rig of a yacht which gives the maximum forward speed. The model includes the effects of heel, wind gradient, and the presence of a gap between the foot of the sail and the deck. The aerodynamic performance of the rig is predicted using a simple numerical implementation of lifting line theory whilst the hydrodynamics of the hull are predicted from experiment data.
