This paper presents the results of experimental tests conducted to study the aerodynamic performance of sailing dhows. The investigation emerged from the interest shown by designers and sail-makers to understand how these sails perform, since they have never been studied before. The 43ft/13.lm and 60ft/18m classes have been tested in a wind tunnel where the effects of varying several parameters were investigated.These parameters were: heel angle, apparent wind angle, bending and stiffness of the yard, optimisation of the trimming and the influence of the mizzen on the mainsail. This is the first investigation where the aerodynamic performance of the lateen sails on sailing dhows has been investigated in a wind tunnel study.
