Stability of weight and shape and excellent performance
The great stability which give the shapes allows not only to increase the power but also a greater tolerance of the sail so as to require less frequent reduction Note from the graph the big righting moment.
Nothing magical but 2 success factors:
large hull shape ;
ratio of keel weight /displacement of approximately 40% markedly superior to the standard cruise boats of equal size.
Result: a high speed in full comfort.
Upwind performance are good especially considering that it is cruising yacht.
STIX (Stability Index) = 47
