Windsurfing : an extreme form of material and embodied interaction?

This paper makes reference to the development of water based board sports in the world of adventure or action games. With a specific focus on windsurfing, we use Parlebas (1999) and Warnier's (2001) theoretical interests in the praxaeology of physical learning as well as Mauss' (1935) work on techniques of the body. We also consider the implications of Csikzentimihalyi's notion of flow (1975). We argue that windsurfing equipment should not merely be seen as protection but rather as status objects through which extreme lifestyles are embodied and embodying

Hydrofoiling Europe-Dinghy

The aim of this master thesis was to develop and build a prototype of separate hydrofoils compatible with a Europe-dinghy (A common, single sail, one-person dinghy), to be used as a proof of concept. This was to be done without causing any permanent changes to the dinghy’s hull. The consulting firm Essiq AB supported the project. Extensive benchmarking of existing foiling dinghies, already on the market, was carried out. Based on this, concepts of different configurations of a hydrofoiling Europe-dinghy were generated. After choosing the most promising concept, it was further refined. Simulations in computational fluid dynamics (CFD), and theoretical calculations were completed to optimize the final design. A prototype of the final design was built and tested. The test proved positive, with successful foiling during shorter periods of time. Nevertheless, the prototype will need some further refinements in order to reach its full potential. The conclusion drawn was that this was a successful proof of concept, and that attaching separate hydrofoils to a Europe-dinghy is therefore a viable option

This discussion paper proposes a way for the South Coast Estuarine Fishery to address issues relating to the long-term sustainable management and sharing of the fish resource

Measurement and prediction of the resistance of a laser sailing dinghy

This study explores the insight that can be gained into the performance of a conventional sailing dinghy from a program of tanks testing in a range of displacement and trim conditions, and further investigates the extent to which performance can be predicted using a regression approach developed for sailing yachts, with the ultimate aim of developing performance prediction tools customised for sailing dinghies. The upright resistance of a Laser Dinghy is examined through tank-testing at three different displacements and with a range of trims. Results show that residuary resistance is substantially affected by displacement, and that trim can have a beneficial effect at the lower and upper extremes of the speed range. Comparison with tank test results show that the Delft regression approach does not predict the resistance of a Laser particularly accurately, substantially underestimates the weight sensitivity of a Laser, and cannot reliably predict the impact of trim
