The patent describes an improvement for the semisubmerged ship which provides hull extensions for additional buoyancy or increased cargo and fuel storage which do not appreciably create more drag. In one configuration sacks disposed below the level of surface wave action are inflated to permit shallow water operation. Preferably, however, the hull extensions have a meniscoidal cross-sectional configuration and are mounted on the submerged hulls. Particularly in the case of the meniscodial-shaped extensions, the structural integrity of the semisubmerged ship is not compromised and the ship's capabiltiy for high-speed operation remains substantially unimparied since the hull extensions do not appreciably create excessive drag. Whatever configuration is chosen, the hull extensions are either permanently or releasably coupled to the hulls to allow flexibility in range and payload.
