In this paper, the deficiency of initial stability, as a general measure of ship stability, is indicated. The variability of the main parameters affecting initial and dynamical stability is discussed. Particular emphasis being placed on the calculation of the risk of losing ship stability. Because of the lack of adequate statistical data to establish the mathematical model representing the random variation of the relevant parameters associated with initial and dynamical stability, a truncated normal probability density function is assumed. Therefore, initial and dynamical stability also follow a truncated normal distribution by virtue of statistical independence. However, for the sake of simplicity, the calculation of the risk of capsizing, or losing GM; is based on a normal probability density function. No attempt is made to establish or examine stability standards and criteria. Problems regarding damage stability, stability of ships among waves, the carriage of bulk cargo and the effects of forward motion are outside the scope of this paper.
