The inviscid lifting-line flow model is used by including a quadrature method to efficiently compute sail pressure loads. The structural calculation is performed with a quasi-static resolution by using a dynamic backward Euler scheme, in order to improve the computation convergence. A specific thickness sail approach is also proposed to make the FSI solving easier. The assembly of these flow and structural methods leads to a fast and robust strategy to compute nonlinear FSI on yacht sails, and the proposed approach is applied on a complex semi-rigid composite mainsail. %G English %L hal-02493825 %U https://hal.science/hal-02493825 %~ UNIV-BREST %~ ENSTA-BRETAGNE %~ CNRS %~ UNIV-UBS %~ UBS %~ ENIB %~ IRDL %~ ENSTA-BRETAGNE-MECA %~ TEST-HALCNRS %~ ENSTA-BRETAGNE-PTR3-IRDL
