Paper Title: A Fully Integrated Sail-Rig Analysis Method



S Malpede and F Nasato, SMAR Azure, UK


This paper presents a method to analyse the rigs of sailing yachts in a timely, cost-effective and versatile manner. Mast and rig design cover an important role in maximising sailing yacht performance. The design of optimal rigs should consider realistic sail loads; conversely the design of an optimal sail-plan should take into account particular rig configuration and structural behaviour. A method is presented for simulating the structural behaviour of rigs under aeroelastic sails loads in upwind sailing conditions. The method consists of two main components: DESIGN, where rig and sails geometry and materials are defined; ANALYSIS, where the rig is analysed under the calculated sails loads in specified trim and sailing conditions. Design, meshing and analysis phases are fully integrated in a single software platform, which allows the comparison of alternative solutions. The sail-rig analysis is non-linear and can be applied to fibre-membrane sails.
