The M-hull is a non-conventional captured air design which transitions automatically and efficiently through hydrostatic, hydrodynamic and aerostatic lift modes with increasing speeds. It has demonstrated on several commercial and military craft the ability to transcend the limitations of conventional hull forms.
The hull geometry and the captured air plenums of the M-hull allow a ship to automatically and naturally seek the most efficient form of lift depending on speed, payload and sea condition. The drag curve for these vessels is almost linear without the typical drag hump across the entire lift range hydrostatic, hydrodynamic and aerostatic. This remarkable characteristic is already demonstrated on several small vessels, and the scalability of the design by combining two or more M-hulls side-by-side holds promise for a new breed of large military craft. The multi M-hull solution could allow large combat and transport ships to transcend the hull speed limit.
The unique geometry of the M-hull and its incredible performance potential may be scalable to large ship geometries by combining two or more of the hulls transversely to create a multi M-hull vessel. For the first time, large displacement vessels have the potential to overcome their hull speed limit and achieve unprecedented high speeds with the multi M-hull geometry.
