Wavemaking Resistance Calculation of Trimaran

The wavemaking resistance of a new type of trimaran-Ovoid-type Hullform,which was proposed by some Japanese researchers,was calculated using a method based on Noblesse's New Slender-ship Theory.Between the numerical results and the experimental data the comparisons were made,which show satisfactory agreement,especially in high speed range.In addition,the effects of line integral and restricting the wave-steepness of the elementary waves were estimated numerically.Also,the optimization of outer hulls location of the trimaran for minimizing wavemaking resistance was considered.Some useful conclusions were obtained.
