N2 - To evaluate ship manoeuvrability based on numerical simulations, hydrodynamic derivatives which is necessary to express lateral force and yawing moment acting on a ship hull are one of parameters which have much influence on simulated results. It is important to use accurate hydrodynamic derivatives to simulate ship manoeuvring motion precisely. In this paper, sensitivity of simulated ship manoeuvring motion using the hydrodynamic derivatives to measurement error included in measured lateral force and yawing moment is investigated. Furthermore, difference of the sensitivity between hydrodynamic derivatives based on a cubic model and a quadratic model is discussed.
