Abstract: In this investigation first K- and T-figures from the equation of motion, as presented by Nomoto, were determined by means of model experiments. This was done for a cargoliner and a tanker respectively, for different rudder area’s and speeds. After that the steering ability of the human operator was investigated as a logical consequence to the knowledge already available for fast response objects as aircrafts and automobiles. An analysis of the ship’s steering follows, taking into account both the ship’s response and the response of the helmsman. At the end the manoeuvrability on a straight course of these combined responses is discussed taking into account the influences of rudder area, hull form and ship’s size.
