“Development of Proposed ISO 12217 Stability Index for Mono-Hull Sailing Craft”, by Peter van Oossanen, Published in the Proceedings of the 13th Chesapeake Sailing Yacht Symposium, Annapolis, USA, January 1997, pp. 97-119 (ID No. 4565).

This paper describes the work that was carried out in developing the minimum requirement for the angle of vanishing stability, the righting moment at 90 degrees of heel, and the area below the righting moment curve, for mono-hull sailing craft, for implementation in ISO 12217-2. In addition the paper describes and defines the individual factors that compose the Single Stability Index (STIX) in the first version of the standard
