Paper Title: An Overview of Planing Monohulls Transverse Dynamic Stability and Possible Implications with Static Intact Stability Rules

The problem of transverse dynamic stability of high speed craft is a complex topic, presently not comprehensively addressed in literature, where material on vertical motions and relevant instabilities is more easily available. 
The present work, based on a PhD project [1], reports an overview of existing literature on the topic, focussing then on the Lewandowski methodology assessing the dynamic stability of hard chine monohulls; such methodology has been applied to selected hulls belonging to Series 62, in order to assess the sensitivity of the numerical tool and the influence of various geometrical parameters. Moreover, a comparison between dynamic stability results and existing stability regulations, allowed some possible guidelines to be developed for the preliminary design phase in order to avoid transverse stability problems. The study clearly indicates the need for further studies in order to enhance the applied methodology. To this aim, extensive experimental investigations are deemed essential.
