The clam water resistance as well the components of a trimaran test model with and without appendage is calculated by CFD method in different conditions, taking viscous effect free surface into account, order to investigate trimming sinkage on calculation. flow field around restrained 6 degrees freedom simulated at velocities, numerical results are compared data show good agreement. total main hull, outriggers details discussed. Then, captive analyse sinkage. analysis comparison suggests that some susceptible gesture. After that, T-foil resistance, gesture calculated. experimental also shows agreement, analyzed.
