America’s Cup – AC72 Wingsail

Wing Wings were new in AC34 so we spent a lot of time understanding the wing; how it needed to work, when to chase max-lift and when to focus on drag, how it interacted with the sails and how the crew would interact with it, what loads it produced and how the structure responded and deformed under those loads. We designed a wing that would give the yacht strong performance and flexibility over a range of conditions but the real challenge was getting it into optimal trim over a range of conditions and keeping it working through manoeuvres. A real team effort!
