In the present study, multi-fidelity modeling of the Delft catamaran is performed including captive, self-propulsion, and prescribed trim and sinkage simulations. High-fidelity simulations are conducted first to verify the computational setup and validate the computational results. A low-fidelity force and moment propulsion model is implemented based on the high-fidelity simulation results and a hydrostatic correlation, which is applied to self-propulsion simulations. The low-fidelity propulsion model trained based on the high-fidelity computational data shows better simulation results (errors less than 5%D) than using the hydrostatic correlation. The computations are accelerated by a factor up to 8 using the low-fidelity model. Issues for the computational setup including center of gravity, displacement with waterjet system, pump curve, and waterjet flow analysis methods are also addressed. Future work will be focused on the waterjet propelled Generic Prismatic Planing Hull (GPPH) and extending the analysis to maneuvering conditions.
