Abstract:

A three-degree-of-freedom mathematical model has been developed to describe the zigzag manoeuvring behaviour of a prototype hull form used in the Royal Australian Navy precursor mine sweeping drone boat. The model predicts the yaw rate of the vessel in response to the angle of thrust that a single outboard motor makes with respect to the centre line of the boat. The outboard motor is assumed to supply a constant thrust. This report describes the development of the model from first principles and its transformation into a form suitable for use in closed loop control modelling. The coefficients of the model were determined using full scale manoeuvring data for the prototype hull form. Hydrodynamics, Manoeuvring
