2.4. Yaw checking test

Zigzag (or Kempf) manoeuvre The manoeuvre provides a qualitative measure of the effectiveness of the rudder to initiate and check changes of heading. The manoeuvre is performed in the following manner. With the ship steaming at a uniform speed and on a constant heading a nominal rudder angle, say 20 degrees, is applied as quickly and as smoothly as possible and held constant until the ships heading has changed by 20 degrees (check angle) from the base course. At this point 20 degrees of opposite rudder is applied and held until the ships heading has crossed the base course and is 20 degrees in the opposite direction, the rudder is then reversed as before. This procedure is repeated until the ships head has passed through the base course 5 times. During the manoeuvre the ships heading and rudder angle are recorded continuously.

Pull out manoeuvre The pull out manoeuvre was developed as a simple test to give a quick indication of a ships course stability. The ship is held on steady course and at a steady speed. A rudder angle of approximately 20 degrees is applied and the ship allowed to achieve a steady rate of turn; at this point the rudder is returned to midships. If the ship is stable the rate of turn will decay to zero for turns to both port and starboard. If the ship has a steering bias, then port and starboard turns will decay to the same small rate of turn on whichever hand the bias exists. If the ship is unstable then the rate of turn will reduce to some residual rate of turn.
