A New Experimental Trials for Obtaining The Added Wave Resistance of Sailing Yacht

抄録

The fact that the next America's Cup will Be held at New Zealand, with its rough sea condition will require a strong research in the added resistance in waves. An experimental procedure and equipment that allow the model to be experimented as close as possible to its acutual sailing condition will result in accurate data and a winner design. Firstly, the free running technique is developed in this article to obtain the results in still water and tried to figure out the ap plicability of this technique in waves for the upright and yawed conditions. The result for even keel are in good agreement with semi-empirical results found in the references. The results in running condition show a good trend but for obtaining quantitatively good results, further improvement will be needed.
