A yacht's stability, or a yacht's natural tendency to float up-right, is created by a multitude of factors.
Those factors include: hull shape, center of gravity, and waterline beam. It is complicated by variables
that are not easy to calculate such as shifting cargo, and fluids moving within and between tanks. Therefore
it is common to "incline" a yacht such as SAILS to find out how stable she really is in the real world.
This is the Stability Curve of Sails as measured by Jay Benford in July of 2004. You will notice that the
righting arm remains positive and high, as the angle of heel increases. Benford concludes;
"She has a full range of stability, with a powerful feeling motion" .
