This study develops an efficient numerical algorithm to predict wave-resistance performance of a catamaran hull. The developed numerical algorithm is applied to evaluate wave-resistance performance for two different twin hull forms with a asymmetric and a symmetric mono hull. Numerical calculations and model tests are compared to validate a developed numerical algorithm adopted in the current work. Comparisons are carried out through the sinkage at the bow and stern, the trim and the wave-making resistance coefficient. Model test is performed in order to verify the numerical results. The comparative analysis study regarding hydrodynamic characteristic of different twin hull forms is worthy of application in the catamaran hull form development stage.
