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...


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 re...
