Broaching-To: A Proposed Definition and Analysis Method

Abstract

A non-linear mathematical model is developed to investigate the behavior of vessels operating in following seas. The effect of the position of the vessel in the wave on the maneuvering characteristics, the wave forces, the rudder effectiveness and the transverse stability is taken into account. A full investigation into the behavior of vessels operating in following seas is hampered by the well known problem that the response of such a non-linear system is highly dependent on the initial conditions.
