Description: The present work reports the first systematic results obtained in wind tunnel and at full scale with theexperimental apparatus developed within the joint project among Politecnico di Milano, North Sails andCSEM. The steady state upwind aerodynamics of sailing yachts are investigated through the contemporarymeasurement of global forces, distributed pressures and sail flying shapes, and with numerical simulationsbased on Potential Theory and Navier-Stokes equations.The wind tunnel of Politecnico di Milano and the Sailing Yacht Lab (SYL), used for full scale investigations,are described together with the measurement systems adopted for recording forces, pressures and sailshapes. The aerodynamic loads are obtained through dedicated arrangements of load cells; the pressuredistributions on sail sections are evaluated with integrated systems of customized local measurementsolutions and MEMS sensors; the sail flying shapes are detected thanks to two laser scanners based of theTime of Flight technology. The experimental procedures adopted during tests are presented and discussedin relation with the aim of the work.
