Abstract

A hydroplaning vessel with several stability and handling design improvements. It has an enhanced reactive suspension and inner hull lift system positioned in the vessel between a set of separating inner and outer hulls. The outer hull does not float on its own as it has numerous fixed louvers formed there through and also has an open transom. Steering and braking are accomplished by a set of rear elevon flaps affixed to the outer hull. The drive unit resides in the inner hull and is connected by an annular drive transmission which is connected to the jet or prop drive which resides on the outer hull.

Claims

1. A hydroplaning vessel comprising:

a non floatable outer hull with an open transom;

a floatable inner hull; and

a suspension and inner hull lift system;

wherein said inner hull is partially cradled within, and movably affixed to said outer hull by said suspension and inner hull lift system.

2. The hydroplaning vessel of claim 1 wherein said outer hull has a bottom surface with at least one open, fixed louver formed there through.

3. The hydroplaning vessel of claim 2 wherein said at least one fixed louver is angled with respect to said bottom surface such that said fixed louver has a leading edge nearest a bow of said vessel that is vertically raised with respect to a trailing edge of said fixed louver that is nearest a stern of said vessel.

4. The hydroplaning vessel of claim 1 wherein said suspension and inner hull lift system is vertically extendable so as to be able to raise said inner hull a vertical distance above said outer hull.

5. The hydroplaning vessel of claim 4 wherein said suspension and inner hull lift system comprises:

two linear series of base plates that lie substantially parallel to each other and along a longitudinal axis of the vessel and are rigidly affixed to said outer hull;

two linear rail boxes that lie substantially parallel to each other and along a longitudinal axis of the vessel and are rigidly affixed to said inner hull; and

at least two struts having a lower end pivotally connected to said base plate and an upper end pivotally connected to said rail box;

wherein said suspension and inner hull lift system is adapted to raise and lower said linear rail boxes vertically with respect to said series of base plates.

6. The hydroplaning vessel of claim 5 wherein said struts pivotally reside between said base plate and said rail box at a first acute angle with respect to a longitudinal axis of said outer hull when said inner hull is fully lowered into said outer hull, and said struts reside between said base plate and said rail box at a second acute angle with respect to said longitudinal axis of said outer hull when said inner hull is fully raised from said outer hull.

7. The hydroplaning vessel of claim 6 wherein said second acute angle is larger than said first acute angle.

8. The hydroplaning vessel of claim 5 wherein said suspension and inner hull lift system further comprises:

at least two reversing rotational drive motors each housed within one of said rail boxes;

a series of parallel spacer plates rigidly affixed within each said rail box, that reside normal to a linear axis of said rail box and have an orifice formed therethrough and a pair of shock absorber guides extending normally from said spacer plates;

at least two linear, threaded drive rods each housed in one of said rail boxes and affixed at a first end to one of said drive motors and rotationally supported in said orifices formed in said spacer plates;

a series of floating nuts each nut threadingly engaged onto one of said drive rods and affixed to a shock absorber cylinder mount;

a series of said shock absorber cylinder mounts each mount affixed to a shock absorber cylinder and having an upper axle thereon with a pair of ends matingly engaged for sliding movement in one of said shock absorber guides;

a series of paired identical gusset plates each pair extending from an upper end of one said strut;

a series of shock absorber rod mounts, each rod mount affixed to a shock absorber rod and having a lower axle thereon that is affixed between said paired, parallel gusset plates;

a series of shock absorbers each having a first end with a rod and a second end with a cylinder that retractably and slidingly houses said rod, wherein each of said shock absorbers is connected between one of said shock absorber guides on said rail boxes and one of said gusset plates on said struts;

wherein said drive motors rotate to advance said floating nuts to push or pull on said shock absorbers to move said struts between said first acute angle and said second acute angle.

9. The hydroplaning vessel of claim 4 further comprising:

a propulsion system;

a power source for said jet drive; and

a pivotable transmission connected at an upper end to said power source and connected at a lower end to said propulsion system.

10. The hydroplaning vessel of claim 9 wherein said transmission can pivot at its connection to said power source and can pivot at its connection to said jet drive independently.

11. The hydroplaning vessel of claim 10 further comprising:

an upper gearbox containing a first set of four grouped, 45 degree cut, beveled ring gears that are held in an enmeshed, square configuration;

a substantially similar lower gearbox containing a second set of four grouped, 45 degree cut, beveled ring gears that are held in an enmeshed, square configuration; and

a splined, telescoping driveshaft connected at a first end to said upper gearbox and connected at a second end to said lower gearbox.

14. The hydroplaning vessel of claim 3 further comprising:

a steering and braking system utilizing a series of four adjustable elevons pivotally affixed to said outer hull; and

an elevon manipulation system to tilt the angle of said elevons in response to a mechanical signal from an operator.

15. The hydroplaning vessel of claim 14 wherein each of said said elevon'"'"'s tilt angle is manipulated to correspond to the tilt angle of either one other elevon or all three other elevons, but never only two of said other elevons.

12. The hydroplaning vessel of claim 12 further comprising:

said upper gearbox with

an upper gearbox housing;

a first right beveled ring gear;

a first left beveled ring gear;

a first front beveled ring gear;

a first rear beveled ring gear; and

a first common axle extending through the center of said first right beveled ring gear and said first left beveled ring gear that is supported in said upper gearbox housing so as to rotationally constrain said first right beveled ring gear and said first left beveled ring gear in said upper gearbox housing;

said lower gearbox with a lower gearbox housing;

a second right beveled ring gear;

a second left beveled ring gear;

a second front beveled ring gear;

a second rear beveled ring gear; and

a second common axle extending through the center of said second right beveled ring gear and said second left beveled ring gear that is supported in said lower gearbox housing so as to rotationally constrain said second right beveled ring gear and said second left beveled ring gear in said lower gearbox housing;

wherein said driveshaft extends normally from the second front beveled ring gear and from the first rear beveled ring gear so as to operationally connect the two gearboxes.

13. The hydroplaning vessel of claim 12 further comprising:
