Abstract : Experiments were conducted on a floating circular cylinder to determine the effect on roll damping of changes in transverse metacentric height GM. The relationship between log decrement (delta) and GM is defined, both graphically and by means of an empirical equation which shows that delta varies inversely as the square root of GM. In addition, the total energy lost per cycle and the energy losses due to wavemaking are discussed. (Author)
