An Inflatable Wingsail

Rigid wings are the future… The America's Cup has proved that. Yet away from the world of racing, cruisers also need to be able to dump and to reef the sails easily. This rig aims to do this. It's called the IWS (Inflated Wing Sails). It stays stable in all types of wind conditions, needs no complex fittings (no winches, halyards or shrouds) and the telescopic mast in particular helps to make it easy to dump or reduce the sails…
