This project's objective is to develop a model of the heave and pitch dynamics for a shallow draft surface vehicle. The model developed uses a novel approach of representing the ship dynamics in the frequency domain. The model is based on theoretical first-principles involving highly nonlinear equations that depend on the water wave frequency. Compared to time domain modeling and simulation approaches, the frequency domain model provides greater insight to the surface vehicle's behavior over a wider operating range. To validate the model, experimental data from towing tank experiments with a 3 meter, shallow draft boat is compared to theoretical model results. The experimental data compares well with the model.
