America’s Cup- Competitive environment focused on performance- Large highly stressed structures in advanced composite materials- Closely monitored aerodynamic and hydrodynamic loads- Disciplined lifecycle monitoring of components

Aeroelastic Design- Sailboat rig as a multi-element wing- Airflow imparts stresses- Stresses cause strains (deformation/elongation)- Strained shape changes flow characteristics- Actual performance depends on aero characteristics of deformed shape

Hull / Fuselage- Localised loads applied by rig, control lines, and appendages- Global loads applied by water (hydrostatic)- Accelerations applied by waves- Hull shape design takes deformed shape into account to maximise performance
