Abstract

This paper examines the problem of the survival of Salter's duck wave-energy device in extreme waves, both experimentally in a narrow tank at Edinburgh University and theoretically, using programs originally designed to study nonlinear ship motions (Vinje & Brevig 1981). Both approaches are essentially two-dimensional, corresponding to waves normally incident upon the duck string, and comparison of the two sets of results for a duck on a fixed axis shows good agreement.
