The simulator presented here solves the 6 degrees of freedom dynamic for two sailboats with interaction. Many parameters are taken into account, even if some of them are roughly estimated yet. The hydrodynamic efforts modelling came from model basin experiments using the planning experiences technique. The complex influence of the three attitude angles, the boat speed and the displacement is taken into account. The aerodynamic interaction between the sail boats is represented by a simple model validated by 3D calculations.
