Over the last ten years there has been a resurgence of interest in the detailed experimental testing of sailing yacht designs. Part 1 of this thesis reports work carried out with the aim of improving test realism and data quality. Reduction of the cost of testing by increasing the rate of data generation is also reported. Constant-Force towing methods in oblique seas were developed. Both Constant-Force and Constant-Velocity data is presented along with a detailed comparison between the two modes. This comparison shows an apparent, frequency dependent, difference of up to +-2% between the two testing modes. During the work on yacht testing techniques a novel stiff DC loadcell was developed to meet the specific requirements of the tank testing apparatus. Part 2 of this thesis reports the work carried out on the development of this transducer. The final prototype achieved a full scale deflection of 10 microns with an overload factor of more than 20 times the rated load.
