Tank tests were carried out using a ship model to capture the low speed maneuvering characteristics with respect to clabbing, pivoting turn and clamshell backing of a ship with VecTwin rudder system. Captive model test was conducted to capture the hydrodynamic force characteristics when the ship speed is zero. Based on the test results, we determined two rudder angle combinations to realize the low speed maneuvering. In free running model tests, we confirmed the clabbing and pivoting turn by combination of starboard rudder angle 105°, port rudder angle -65° and bow thruster operation. The clamshell backing was also confirmed by ±105° for both port and starboard rudder angles. Thus, we found that the ship with VecTwin rudder system has good maneuverability in low speed.
