Advanced Wing Systems is the developer of the SRW (Semi Rigid Wing) sail. This wing sail system is unique in that it uses a pair of fully battened sails which operate in unison to create a rigid aerofoil structure.
This system reduces the weight and cost of the wing and allows simple stowing and reefing. The system also provided significant control over the geometry of the wing allowing optimisation of the wing set-up. Asymmetry, camber, twist and span wise section thickness are all easily controlled. The system has been tried and proven in yachting and has been in use for several years. The implementations in yachting have demonstrated the simplicity, robustness and low weight of the system. The SRW has a very low part count compared to other wing systems and the parts are simple and robust. The design is flexible and can be deployed in stayed or free-standing configurations. The simplicity of the control systems makes it an ideal candidate for automation.
