A catamaran's exceptional stability on the open ocean is governed by the specific geometry of its water plane area and the distance between its twin hulls. When waves tilt the vessel, the center of buoyancy rapidly shifts toward the submerged hull, creating an exceptionally long righting lever, known as GZ, relative to the ship's center of gravity.
This broad stance produces a substantial metacentric height and a powerful restoring moment that forces the craft back upright, preventing the uncomfortable rolling motion that often causes seasickness on monohulls. However, while they resist transverse rolling beautifully, their slender profiles possess less reserve buoyancy forward, making them slightly more prone to pitching in head seas.
