This is a perfect example of form stability. In this case, the shape of the capsized boat itself is contributing more to the inverted stability than the overall vertical center of gravity. This aspect of radical boat design is fully understood and accepted by both the designers and the sailors involved. Beam is often misunderstood. If you look at rating rules over the years, beam is always on the slow side of the equation.
More beam means a slower boat, all else being equal.
But, when you combine ultralight displacement with exaggerated beam and water ballast, you get a boat that when heeled presents a long sliver shape to the water, like a big C-scow. With 4,600 pounds of water ballast applied on top of that beam, this design also has immense sail-carrying power at moderate heeling angles. The record speaks for itself. This is a very fast shape. We will go into the stability subject in greater depth at a later date.
