Research and development within the windsurfing field is comprised purely of previous experience, prototype building and testing on the water. The use of Computer Aided Design (CAD) systems and simulation packages can significantly help in the design and testing phases by optimizing the design before a prototype is built. In the paper, supported by these software tools, the authors show a new patented system, named iDO, developed with the aim to stabilize the windsurf, to allow reducing the initial difficulties that a beginner meets in the learning phase. The design process, from the idea to the manufacturing aspects, with all the technical and technological problems, is described. The validation product was carried out by means of user evaluation questionnaires from sixty-four windsurfing beginners in several countries over world. The results show that the users are significantly satisfied with the product. 展开更多
