Since resolution A.751 (18) was adopted at Assembly in International Maritime Organization, it is important to evaluate at the design stage the compliance of a ship with the resolution A.751 (18). In this paper, a method is proposed in order to roughly but simply estimate the values of manoeuvarability index in the resolution. That is the simplified estimation method by means of the regression equations which derivates from Nomoto's manoeuvring equation. They mainly consist of parameters based on the manoeuvring derivatives expressed by Inoue's formula, the variable considering the effect of stern frame line and the term of rudder force including the effect of manoeuvring motion. The coefficients are determined by the sea trial data in the manoeuvring performance database. It means that every criterion's value of manoeuvrability index except for stopping ability in the resolution can be estimated from the principal dimensions and so on used in the design stage. And it is shown that the estimated values are in good agreement with the ones measured in manoeuvring tests of a ship.
