In this paper the results are presented of an investigation of the minimum satability requirements for ballasted, mono-hull sailing craft. This Standard for the stability of small craft of length less than 24 metres is of particular importance as it will be one of about 30 Standards presently being developed for use in conjunction with the European Directive on Recreational Craft. The paper first of all addresses recent sailing yacht casualties in an attempt to determine potentially dangerous stability characteristics in mono-hull sailing craft. To support the development of stability criteria based on this analysis, the stability data of so-called category I yachts, of which more than 5 vessels were built and/or with a long operational history without any stability-oriented problems, are considered. A proposal is then made for the minimum value of the vanishing angle of positive stability and the righting moment at 90 degrees of heel, for the four stability categories considered. The development of so-called Dynamic Stability Factor is also presented. This take into consideration various factors of importance in a dynamic sense, such as the roll moment of inertia, the loss in waterplane inertia due to the wave through amidships, ect. In the stability Standard under development it is stipulated that a sailingvessel must posses a minimum value for this factor, dependent on the stability category to be assigned.';&&&
