Description: In the history of sailing, specifically the America’s Cup, the development of new technologies and methods for making a boat go faster have led to leaps in the field that have resonated throughout the industry and beyond. One such innovation was that of a wing sail in place of the traditional fabric sail. The recent America’s Cup matches have shown that at high wind speeds and in large applications, the wing sail is much more efficient and capable of producing higher boat speeds than that of a traditional sail. It is worth investigating whether or not these principles hold true for small sailboats at relatively low wind speeds. In this paper, it is shown through theoretical modeling using Computational Fluid Dynamics (CFD) as well as a practical experimentation using a small sailboat that the wing sail performs at least
similar and most of the time better than the traditional sail for the given parameters. The results of this paper prove that the application of wing sails can be used for smaller boats as well as larger boats as was previously known. These results also show that for any use of sailing methodologies, a wing sail can be used instead of a traditional sail for greater performance
