Abstract:

Experiments were conducted with a model of a single-strut-per-hull SWATH ship and three variants Higher GM, Wide Spacing, Deep Draft at zero speed in beam regular and irregular waves. Each model configuration tended to roll at its natural frequency omega when excited by regular waves with a frequency 2 omega, or by irregular waves with a modal frequency of 2 omega. Author
