Abstract

A mirror-image model of the Lucy Ashton was covered with two different ″mesh-type″ roughnesses and tested in a wind tunnel. Total drag and velocity profile measurements are presented. Total drag results are also given for a normal Lucy Ashton model with the same roughness mesh tested in a towing tank. The influence of roughness on the wave drag component was found to be small, implying that the ″interdependence″ of wavemaking and viscous resistance is small.
