The dynamic stability of ships encountering large regular waves from astern is analyzed, with focus on delineating the specific conditions leadingto the uncontrolled tum identified as broaching. The problems formulationtakes into account motions of the actively steered or controls-fixed vessel in surge-sway-yaw-roll with consideration of Froude-Krylov and diffraction wave excitation.Dynamical analysis of surf-riding is carried out for the general case of quartering waves, exploring the route periodic motions-surf riding, loss of stationary stability, turn, capsize. Steady-state andtransient analysis is carried out in the systems multidimensional state-space in order to identify all existing limit sets and locate attracting domains. Broaching from periodic motions is also a part of the investigation.
