Sail optimisation for high speed craft

Research output: Contribution to journalArticlepeer-review


A mathematical model has been developed to predict the straight line speed of a 'speed' sailboard. The sail and fin are modelled using a simple lifting line formulation, whilst the hull is modelled using experimental data originally obtained for the aeronautical industry. The lift distribution over the sail is optimised to produce the maximum ultimate speed of the board subject to the constraint of maximum overturning moment. The optimisation is carried out using a stochastic approach known as simulated annealing which required no explicit relation ships between the various parameters.
