A watercraft steered under power by water-jet propulsion utilizes a water intake ramp in its hull to create a nozzle-like effect to accelerate water loading to the jet pump through a ventral water inlet when under power. The hull has a pair of longitudinal stabilizers that form a tunnel in which the ramp is located. A canopy, which can be removable, encloses a passenger compartment with a steering wheel and one or more passenger seats. Two wings flank the passenger compartment and a pair of hull ramps run steeply downward from the leading edge of each of the wings and extends to the bottom of the hull while a pair of air scoops flanks each side of the passenger compartment and is located above the pair of wings. The forward-most beginnings of the pair of stabilizers relative to a nose section and the pair of wings ride above the surface of the water when the watercraft is under power and the watercraft rides on the back of the pair of stabilizers. The tops of wings are curved in a configuration to give the watercraft top lift and have a reverse curve on their bottom surface relative to the surface of the water to push the hull upward and provide a faster plane for the watercraft to run on the pair of stabilizers. The engine and the driver's passenger seat rest on the center of gravity of the watercraft at the water line when the watercraft is under power.

1. A watercraft, comprising:a jet pump; an engine connected to the jet pump by a shaft; a hull that extends longitudinally, further comprising: a forwardly tapering nose section with a keel that knifes downward from the tip of the nose section; a pair of stabilizers that run longitudinally and spaced apart from each other that form a tunnel that runs substantially the length of the back half of the hull relative to the nose section; a water intake ramp located in the tunnel substantially back from the forward-most beginnings of the pair of stabilizers relative to the nose section, the ramp tapering downwardly from its forward-most beginning relative to the nose section; a ventral water inlet located in the intake ramp for supplying water to the jet pump, the intake ramp providing loading to the jet pump; and a mid-section passenger compartment formed within the hull with at least one passenger seat and a steering control mechanism; an aft end-section that extends laterally, the engine being located in the aft end-section; at least one air intake flanking the mid-section passenger compartment; a pair of wings flanking the passenger compartment and extending laterally therefrom and extending rearward to join the aft end-section, there being a left wing and a right wing; wherein a pair of hull ramps runs steeply downward from the leading edge of each of the pair of wings, extending therefrom to the bottom of the hull, there being a left hull ramp and a right hull ramp; wherein a pair of air scoops flanks each side of the passenger compartment from which the pair of wings extend laterally therefrom, thereby forming a left air scoop and a right air scoop, and one of the pair of air scoops comprises the at least one air intake, the pair of air scoops being located above the pair of wings while the pair of hull ramps are located below the pair of wings; and wherein the hull, the pair of wings, the pair of hull ramps, and the pair of air scoops are bilaterally symmetric with a centerline running through the nose section and the passenger compartment. 2. The watercraft of claim 1, further comprising:a rudder connected to the jet pump. 3. The watercraft of claim 1, wherein the forward-most beginnings of the pair of stabilizers relative to the nose section ride above the surface of the water when the watercraft is under power and the watercraft rides on the pair of stabilizers.4. The watercraft of claim 1, wherein the pair of wings ride above the surface of the water when the watercraft is under power.5. The watercraft of claim 1, wherein the watercraft is steered under power by water-jet propulsion.6. The watercraft of claim 1, wherein the intake ramp is located in the back longitudinal half of the watercraft relative to the nose section.7. The watercraft of claim 1, wherein the pair of wings have a reverse curve on their bottom surface relative to the surface of the water to push the hull upward and provide a faster plane for the watercraft to run on the pair of stabilizers.8. The watercraft of claim 1, wherein the tops of the pair of wings a re curved in a configuration to give the watercraft top lift.9. The watercraft of claim 1, wherein the at least one air intake comprises a pair of air intakes, one being located on each side of the passenger compartment, a first air intake being for air intake to the engine, a second air intake being for ventilation.10. The watercraft of claim 1, wherein the engine rests on the center of gravity of the watercraft at the water line under power.11. The watercraft of claim 1, wherein a driver's passenger seat located within the passenger compartment rests on the center of gravity of the watercraft at the water line under power.12. The watercraft of claim 1, wherein the intake ramp is latitudinally wider than the ventral water inlet.13. The watercraft of claim 1, wherein the intake ramp creates a nozzle-like effect to accelerate water loading to the jet pump when the watercraft is under power.14. The watercraft of claim 1, further comprising:a pair of headlamps that project frontward out of the hull. 15. The watercraft of claim 1, further comprising:at least one accessory rack mounted to the aft end-section. 16. The watercraft of claim 1, further comprising a mid-section canopy.17. The watercraft of claim 16, wherein the mid-section canopy has a transparent window.18. The watercraft of claim 16, wherein the mid-section canopy is detachable from the watercraft.19. The watercraft of claim 16, wherein the mid-section canopy and the hull totally enclose the passenger compartment.20. The watercraft of claim 1, wherein the passenger compartment is configured with only one passenger seat.21. The watercraft of claim 1, wherein the passenger compartment is configured with a plurality of passenger seats.22. The watercraft of claim 21, wherein the passenger compartment has two passenger seats and the second passenger seat is aligned longitudinally behind the first passenger seat relative to the nose section.23. The watercraft of claim 1, wherein the watercraft is steered by a steering wheel located within the passenger compartment.24. The watercraft of claim 1, further comprising:a global positioning system with a display mounted within the passenger compartment. 25.
