A craft including a body having a front end, a rear end, two sides miming between said ends, and an axis running generally from the rear end to the front end; and a water displacement system operable to displace water to propel the craft across water and to displace water to cause the craft to rotate about said axis. The craft includes a ballast tank capable of being at least partially filled with ballast to change a position of a center of gravity of the craft to assist in rotation of the craft when capsized. The craft also includes a rapid filling and emptying system for a ballast system of a craft in addition to a water displacement system, wherein the rapid filling and emptying system includes at least one ballasting intake through which water is passed from the water displacement system into said ballast system; and at least one ballasting outlet through which the water displacement system draws water from the ballast system.

1. A craft including: a body having a front end, a rear end, two sides running between said ends, and an axis running generally from the rear end to the front end;a water displacement system operable to displace water to propel the craft across water, and to displace water to cause the craft to rotate about said axis; anda ballast system, including: a ballast tank capable of being at least partially filled with ballast to change a position of a center of gravity of the craft to assist in rotation of the craft when capsized; anda rapid filling and emptying system, wherein said rapid filling and emptying system includes: at least one ballasting intake through which water is passed from the water displacement system into said ballast system; andat least one ballasting outlet through which said water displacement system draws water from the ballast system, wherein water drawn from said ballast system is used to propel the craft. 2. A craft according to claim 1, wherein the water displacement system includes a drive propulsion system for displacing water to propel the craft across water and a rotate propulsion system for displacing water to cause the craft to rotate about said axis. 3. A craft according to claim 2, wherein the rotate propulsion system includes a plurality of water propulsion systems arranged to generate rotation of the craft about the axis. 4. A craft according to claim 3, wherein the water propulsion systems of the rotate propulsion system are located intermediate the ends of the craft. 5. A craft according to claim 1, wherein the water displacement system includes two water propulsion systems through which water is displaced from the craft, each one of said propulsion systems being positioned closer than the other to one of said sides of the craft. 6. A craft according to claim 5, wherein the water propulsion systems are each moveable between a drive position for displacing water to propel the craft across water and a rotate position for displacing water to generate rotation of the craft about said axis. 7. A craft according to claim 6, wherein the water propulsion systems are water jet propulsion systems including jet inlets and jet outlets. 8. A craft according to claim 7, wherein the jet outlets include diverters, and the water propulsion systems are moveable between drive positions and rotate positions by maneuvering the diverters over the jet outlets to redirect flows therefrom. 9. A craft according to claim 7, wherein the water propulsion systems move between said drive positions and said rotate positions by pivoting said jet outlets. 10. A ballast system according to claim 1, wherein the ballast tank includes a bottom ballast tank capable, when in use, of being at least partially filled to draw the center of gravity of the craft towards a bottom of the craft to assist in rotation of the craft when capsized. 11. A ballast system according to claim 10, wherein, when in use, the bottom ballast tank occupies substantially all of the internal volume of the craft. 12. A ballast system according to claim 1, wherein the ballast tank includes a side ballast tank capable, when in use, of being at least partially filled to draw the center of gravity of the craft towards a respective side of the craft to assist in rotation of the craft when capsized. 13. A ballast system according to claim 12, wherein the side ballast tank is in fluid communication with a bottom ballast tank, to allow water from the bottom ballast tank to flow into the side ballast tank. 14. A ballast system according to claim 1, wherein the ballast system is adapted to reduce a torque required to right the craft by filling the ballast tank from one end of the craft only. 15. A ballast system according to claim 14, wherein the ballast tank includes a gate or valve positioned to be submerged under water when the craft is upside down so that, when open, water can fill the ballast tank from said end of the craft. 16. A ballast system according to claim 14, including a pump for pumping water into the ballast tank from said end of the craft. 17. A ballast system according to claim 14, wherein said end is a rear end of the craft. 18. A rapid filling and emptying system according to claim 1, further including a common orifice and a valve, wherein the ballasting outlet and ballasting inlet are configured to be coupled to the ballast system at the common orifice, and the valve is positionable to close one or both of the ballasting inlet and ballasting outlet. 19. A rapid filling and emptying system according to claim 1, being capable of filling the ballast system with sufficient ballast to substantially increase the mass of the craft and thereby lower the position of the craft in water, in order to substantially reduce the portion of the craft visible above water. 20. A craft according to claim 1, wherein the body includes a top and the water displacement system includes at least one auxiliary intake positioned on at least one of the sides and top, through which water can be drawn into the water displacement system. 21. A craft according to claim 20, wherein the at least one auxiliary intake includes a plurality of auxiliary intakes positioned around at least one of the sides and top. 22. A craft according to claim 21, wherein the plurality of auxiliary intakes are positioned around the craft to provide a continuous flow of water to the water displacement system while the craft rotates about the axis. 23. A craft, including: a body having a front end, a rear end, two sides running between said ends, and an axis running generally from the rear end to the front end; anda water displacement system operable to displace water to propel the craft across water, and to displace water to cause the craft to rotate about said axis, wherein the body includes a top and the water displacement system includes at least one auxiliary intake positioned on at least one of the sides and top, through which water can be drawn into the water displacement system and, wherein the or each auxiliary intake is moveable between an open condition and a closed condition, and includes an intake pipe to which is mounted a sensor for determining whether the flow through the or each auxiliary intake is sufficient to warrant the or each auxiliary intake to remain in the open condition. 24. A craft according to claim 23, wherein the or each sensor is a laser for determining the optical density of the water in the pipe of the or each auxiliary intake.
