Research on Motion Reduction of a T-Foil on the Wave-Piercing Catamaran

When the wave-piercing catamaran (WPC) sails on the waves, if the wavelength is near to the length of WPC, the pitching amplitude will be large. After years of research, it is found that installing the appendage is a good method of reducing shaking. T-foil is a good choice. In order to study the anti-pitching effect of the T-foil, this paper establishes the motion model of the wave-piercing catamaran and solves the motion equations. The result shows that the amplitude of pitting and heaving can be reduced by 10%. (paper)
