The invention relates to a rig for sailing and windsurfing, consisting of a textile wing membrane and a guide and mounting structure. The rig uses the so-called vortex coil effect (also known as eddy reel effect). The basic principle of the leaflet geometry is the so-called "crab claws rig" modeled.

Chapter Summaries
- The document begins with a detailed description of the innovative rig for sailing surfboards, highlighting its key features: a textile wing membrane and a guide and mounting structure. The rig is designed to leverage the vortex coil effect, a phenomenon that occurs when multiple vortices interact to create a powerful, concentrated flow.
- The next section provides a comprehensive review of the historical development and current understanding of the "crab claws-rig," a traditional sailing technique inspired by the design of outrigger canoes. It acknowledges the advancements made in theoretical understanding and experimental testing of this rig, particularly its potential for improved performance.
- A subsequent section dives into the scientific underpinnings of the vortex coil effect. It discusses the phenomenon of induced edge vortexes and their role in lift generation. The document then explores the evolution of knowledge regarding vortex coil formation, referencing research and patents from the last century.
- The document further explores the connection between biology and technology, highlighting the natural application of the vortex coil effect in the design of slow-sailing birds. The text explains how these birds utilize the vortex coil effect to generate efficient lift and reduce drag, providing a strong basis for the application of this principle in engineering.
- The document concludes by outlining the key challenges associated with adapting the crab claws-rig for use on surfboards. It then presents a detailed proposal for a solution that addresses these challenges and effectively implements the vortex coil effect for optimized wind-powered propulsion.
