Over the past few decades a considerable number of studies have been made on course stability of tow and towed vessels. This paper is intended as an investigation of the mathematical model for the maneuvering motions of tow and towed vessels. The mathematical model has some features that distinguish it from ordinary models. The mathematical model consists of two separate procedure: the first part is usual towed motions which keep a tow line under high tension, while the second part is a stopping or hard turning motions which are loose from a tow line. The first part take on a course stability in towed motions. The second part is related to a safety operation between a tow vessel and a towed vessel. The hydrodynamic models are based on MMG (Mathematical Modeling Group in Japan) model. The author conducted the free running model experiments and numerical simulation studies to validate the mathematical model. The calculation results are in good agreement with experiments results.
