The high-speed-towed fish preserve is a new type vessel about 15.6m long with a fish preserve capacity of 200m^3. The vessel is supposed to be towed efficiently with a lighter draft (about 0.8m) at a maximum speed of about 10 knots (F_n= 0.42). A great deal of effort has been made on the course stability for the towed-vessel, what seems to be lacking, however, is a control method of the course stability. This paper is intended as an investigation of the control method for a course stability of the towed-vessel. We conducted the free running model experiments in a bay. Model experiments were conducted using a 1/12^<th> scale(1.3m) model. Also we performed the simulation studies to investigate the course stability for our control method. The results of experiments were used for validating our simulation studies. The results of our experiments and simulations sudies are described and discussed.
