Design and validation of a wing sail

The sails in the shape of an aircraft wing or wing-sails provideg better performance than conventional sails, with more lift and less drag. They have proven their superiority in the America’s Cup. The goal is to apply to workind ships, which imposes additional constraints.
AVT has decided to build an automated wing-sail and to validate it on the Grand Largue, replacing middle jib.
A Youkou Lili served as a prototype for the feasibility study.
