A 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 (Fn=0.42). The course stability of the vessel depends on the hydrodynamic forces acting on the hull in maneuvering motions. This paper is intended as an investigation of the course stability for the vessel by the experimental study. We conducted the captive model experiments to measure the hydrodynamic forces in maneuvering motions. The model experiments were conducted the oblique motion tests and the rotating arm tests using a 1/12^<th> scale (1.3m) model. The results of our experiments and the course stability characteristics are described and discussed.
