The high-speed-towed fish preserve is a new type vessel about 15.6m long with a fish preserve capacity of 200m^3. The ship will be able to be towed efficiently with a lighter draft(about0.8m). Since the maximum speed of the ship is over 8 to 10 knots (Fn≧0.33). But it depend on a tug boat's power. The course stability of the ship will affected by the ship's speed, the trims and towline's positions. It is important to clear the relation between ship's speed and course stability. In this paper, we present the course stability characteristics in high-speed range. Also we discussed the effect of the trims and towline's positions. We conducted circular tank experiment tests using l/25thscale(0.624m) modeles and simulation studies of the course stability. The results of our experiments and simulation studies are described and discussed below.
