摘要：
It is meaningful to study the wave-resistance reduction of an asymmetric catamaran because of interference effects between the two sets of ship-generated waves. The influence of lateral separation and longitudinal stagger on the resistance and the wave interference are analyzed within this paper. Numerical calculations of resistance, sinkage and trim of the asymmetric catamaran are carried out for several Froude number ranging from 0.24 to 0.48, for six different lateral separations and four longitudinal staggers. Verification of numerical results is provided. The model tests are then carried out for three stagger distances to validate the numerical results. Results of this study indicate that the wave-resistance can be effectively reduced by certain hull layouts at different Froude numbers.
