• The effect of uncertainty in the estimation of the parameters of MMG maneuvering model is studied. The changes of one of the model parameters as well as multiple changes of the parameters are modeled. The analysis of the variance of the maneuvering indices points out a distinct influence of the model parameters on the resultant uncertainty of the maneuvering indices. A simple ranking procedure orders the tested parameters of the model according to their influence on the maneuverability and uncertainty. The relative sensitivity parameters are introduced for easier discription of the model parameters' influence. The uncertainty of the maneuvering index estimation is a function of MMG model parameters; it is large for dynamically unstable ships that have been tested. Therefore the estimation of the model parameters' errors and resulting confidence bounds of the maneuvering indices' estimates is advised.
