This thesis focuses on the problem of predicting the maneuvering characteristic of high-speed craft. A mathematical model is derived based on equations by Lewandowski and Denny-Hubble in order to find the fundamental maneuvering characteristics. The model is developed in the MATLAB Simulink in-time domain with the help of Nomoto’s first-order model, which encapsulates the fundamental dynamics of turning on the horizontal plane. After the development of the model, Predator and Prey interactions are analyzed in order to estimate helmsman reaction when the vessel is attacked by a missile. Three different attacking situations are analyzed in missile-vessel interactions for the safety of the vessel, and the optimum distance has been found to start the escape maneuver. According to these escape situations, the missile should maintain a certain g-force to make an adequate turn and hit the vessel. These critical g-forces are calculated for each situation.
