The angle of heel on account of turning is one of the mandatory stability criteria for passenger ships. Formula used for calculations of this criterion contained in the International Code on Intact Stability [13] is criticized at present. Agendas of the Sub-committee on Ship Design and Construction (SDC) for the first (2014) and the second (2015) sessions contain the item on revision of this criterion and corresponding regulation. The paper presents some shortcomings of the criterion. Turning tests of a freely maneuvering model of a passenger ship have been executed aiming at gathering data for the future discussion and its facilitation. The paper presents results of the tests together with preliminary conclusions that confirm the need of the revision of the regulation and put forward concerns on application of such values as initial metacentric height (GMo) and righting lever curve (GZ(?)) calculated for a ship laying still for calculation of a ship’s heel caused by turn.
