【Abstract】 By approximating the lines of the demi-hull and the main body’s section with 7-order polynomial, the authors calculate the wave-making resistance of a SWATH based on the linear theory. Among which the frictional resistance is calculated on the hypothesis of equivalent plank, while the shape resistance is calculated by the method of 1 + k. Comparing with the numerical and experimental results shows that the estimation method of the resistance performance for SWATH proposed here is practical and effective.更多还原
