A personal watercraft having a multi-hull is disclosed herein. In an embodiment the multi-hull is a catamaran hull, for example two pontoons connected by a cross structure which form an air passage between the hull and the surface of the water upon launching. In alternative embodiments, the multi-hull is a SWATH hull or a trimaran hull. Also, disclosed herein is a personal watercraft having two water outlets from the propulsion system. In an embodiment, the two or more water outlets are disposed between the pontoons. In another embodiment, each pontoon has a water outlet mounted thereto or integral therewith. In another embodiment, each water outlet is positioned within the cross-sectional area of the pontoon. Also, disclosed herein is a method for increasing the speed at which a personal watercraft is propelled comprising using a multi-hull design to decrease the hydrodynamic resistance on the watercraft.
