To predict the power of the 31m boat at 17 knots cursing speed. The CFD Simulation was performed and the results were validated with experimental results and found aligned. The percentage error was under range as per the International Towing Tank (ITTC). The STAR CCM+ can allow Six Degrees of Freedom (DOF) but as per the client’s requirement hull was allowed to move in 2 DOF, Heave, and dynamic Pitch
