The invention relates to a hydro-jet powered water vehicle having a jet motor and a seat for a passenger, the seat being provided with means for the feet of the passenger. The vehicle is designed so that, when it does not carry any load, the floating center of the vehicle is located between the seat and one end of the vehicle and so that an open channel extends between the front end and the back end of the vehicle.

A hydro-jet powered water vehicle comprising two hulls provided with planing means so that, when a minimum forward speed is reached, the hulls substantially plane on the water surface, said vehicle being adapted for carrying at least one passenger with a load lower to a maximum authorized load, said vehicle when unloaded having an unloaded floating line and comprising: (a) two hulls having each a vertical face extending between a front end, a back end and a lower end line, said hulls being agenced so that the vertical faces are parallel together and so as to define between the vertical parallel faces an open channel having a front open end, a back open end and a vertical symmetrical plane, the lower end lines of the hulls defining there between a surface which is substantially horizontal when the minimum planing forward speed is reached and being inclined with respect to the horizontal when the vehicle is unloaded, the inclination of said lower end lines with respect to the horizontal being such that the part of said lower end lines adjacent to the front end is less immerged than the part of the said lower end lines adjacent to the back end, said hulls having each an underneath face comprising planar parts which substantially define all together a plane forming an angle of 70°-85°with the vertical symmetrical plane of the open channel, said planar parts acting as planing means; (b) a jet motor with a motor, a turbine driven by said motor and a water nozzle, said motor being attached to the hulls, in the vicinity of their back end and so as to be located between the two vertical parallel faces of the hulls, said turbine sucking water through an opening extending below the surface defined between the lower end lines of the hulls and expelling water in the nozzle, said nozzle being located between the said two vertical parallel faces of the hulls defining the open channel, the water nozzle being at least substantially under the water level for a forward speed of the vehicle lower to the minimum forward speed required for the planing of the vehicle, while, for a forward speed of the vehicle higher than the minimum forward speed required for than planing of the vehicle, the water nozzle is above the water level; (c) at least one seat for a passenger, said seat being attached to the hulls and so as to be located between the two vertical parallel faces of the hulls, said seat being provided with means on which rest the feet of the passenger; (d) means for controlling the motion of the vehicle, and (e) a shaped plate comprising two parts which are located between the opening of the turbine and the front open end of the channel, a first part being inclined with respect to the surface defined between the lower end lines of the hulls and having a lower end line perpendicular to the symmetrical plane of the channel and situated just below the surface defined between the lower end lines of the hulls, while the second part located between the opening of the turbine and the lower end line of the first part is parallel to the surface defined between the lower end lines of the hulls; said water vehicle, when unloaded having such a floating center that the seat is located between, on the one hand, the vertical plane perpendicular to the symmetrical plane and passing through the floating center and, on the other hand, the front open end of the channel, while the channel is－such that for the unloaded water vehicle, at most 50% of the vertical open surface of the channel extending in a vertical plane perpendicular to the symmetrical plane, and passing through the floating center is located under the unloaded floating line, and－such that, for the vehicle carrying the maximum authorized load, the channel has a passage above the floating line from the front open end of the channel up to the back open end of the channel, for each open vertical surface of the channel perpendicular to the symmetrical plane thereof, the minimum vertical surface of the said passage being at least 10% of the considered open vertical surface of the channel.
