The surf is still a sport that is governed by the sensations. The vast majority of innovations in design and manufacture of tables and analysis are surfing technique based on procedures of "trial and error" and the experience of coaches and surfers. Proponents of this joint project, and TECNALIA PUKAS, trying to "put numbers to feelings" and to provide data so far unquantified be applied directly to improve the performance of surfboards, the technical performance of the surfers and measuring competition parameters. The research will usher in a revolution in the manufacturing of surfboards, since it will have a map of the critical points and their properties, enabling it to incorporate different materials in quantities and with properties determined at points in the size surfboards. To carry out the project, it has been necessary on the one hand to install the electronics for data acquisition-sensors and hardware-in surfboard itself, which transfers data to a computer. On the other hand, have characterized the mechanical properties of surfboards, in order to quantify the mechanical behavior of the same and can be adapted to the needs of each surfer. Have also been identified in laboratory tests that have allowed us to quantify the rigidity / flexibility and resistance to breakage of the tables. . . Surfers can improve their technique through the acquisition of quantitative and objective data directly from their surfboards. Donostia-San Sebastian, February 22, 2011. Pukas and Tecnalia (Gipuzkoa-based company) invited the elite surfer Aritz Aranburu to present their research on the mechanical performance of surfboards. The results and conclusions drawn from them open up a whole range of options for the application of technology, training and product development. This research project will revolutionize the manufacturing of surface surfboards as it will provide a map of the critical points and their properties, which will enable the incorporation of a quantity of various materials with known properties in specific locations in the size surfboards. To carry out the project, had to install the electronic data collection - sensors and hardware - in own board to transfer the data to a computer. In addition, we have characterized the mechanical properties of the surfboard in order to quantify the mechanical behavior of these and adapted to the requirements of individual sufered. We have also defined the laboratory tests that allow us to quantify the stiffness and flexibility of joints and their resistance to breakage. In the following video, elite surfers Aritz Aranburu, Hodei Collazo, Mario Azurza Kepa Acero and have been responsible for carrying out the first experiments designed to characterize the stresses affecting surface surfboards as closely as possible. Other pro surfers like Tiago Pires, Joan Duru, Eneko Acero and Tim Boal, is expected to join the project at a later date. . . .
