A method of calculating the aerodynamic pressure field around a solitary sail or a system of main sail and jib is shown. It is based on integral methods derived from a model of a three dimensional incompressible perfect stationary flow by using singularities as sources and doublets. Numerical results are shown as an illustration of the interaction between two lifting surfaces.
