Three stage watercraft

1. A watercraft for three-stage operation, in a first stage the watercraft riding in the water as a boat, in a second stage the watercraft riding on the surface of the water, and in a third stage the watercraft being in contact with the water while also traveling in ground effect above the water, the watercraft comprising:

a hydro-wing being formed by a combined hull and pair of wings, the combined hull and pair of wings having a bottom surface constructed and arranged to contact the water during the first stage, and a top surface opposite the bottom surface constructed and arranged to support a cockpit, and wherein a continuous ground effect surface is formed by the bottom surface of the combined hull and the pair of wings to maintain the watercraft in ground effect during the third stage wherein the hydro-wing is spaced a distance above the water;

at least a single hydrofoil supported by the hydro-wing and constructed and arranged to contact the water in stage two;

a pair of outboard hydro-floats supported on the bottom surface of the hydro-wing on a port and a starboard side thereof;

a pair of air rudders supported by the hydro-wing constructed and arranged to effectuate turning during the second stage of operation and the third stage of operation;

at least one water rudder supported by the hull constructed and arranged to effectuate turning when the rudder is in the water; and

an articulating trim arm operatively connected to an elevator control supported by the hydro-wing, the articulating trim arm remaining in contact with the water during the third stage of operation when the hydro-wing is traveling spaced above the water.

2. The watercraft of claim 1 , wherein the pair of air rudders comprises aft air rudders supported on the rear portion of the hull.

3. The watercraft of claim 2 , further comprising a pair of forward air rudders supported on the forward portion of the hull.

4. The watercraft of claim 1 , further comprising leading edge wing slats constructed and arranged to direct air upward over the top surface of the hydro-wing.

5. The watercraft of claim 1 , wherein the hydro-floats each include one or more concavities constructed and arranged to create a positive turbulence as water passes by the concavity and turns in a vortex to create additional lift of the hydro-wing.

6. The watercraft of claim 1 , wherein the at least a single hydrofoil comprises a forward hydrofoil supported on the forward portion of the hydro-wing, and an aft hydrofoil supported on the rear portion of the hydro-wing.

7. The watercraft of claim 6 , wherein the forward hydrofoil and the aft hydrofoil are movable between a first, in-use position where the forward and aft hydrofoils engage the water and a second, stored position where the forward and aft hydrofoils are positioned under and adjacent the bottom surface of the hydro-wing hull.

8. The watercraft of claim 1 , further comprising:

a steering device operatively connected to a rear, horizontal elevator

wherein the at least a pair of air rudders are operatively attached to at least one water rudder; and

wherein the steering device, horizontal elevator, air rudders and water rudders effectuating turning and steering of the watercraft.

9. The watercraft of claim 1 , wherein the at least a single hydrofoil is constructed and arranged to move between an extended position where the at least single hydrofoil contacts the water in stage two and a stored position where the at least single hydrofoil is positioned upward, in stage three.

10. The watercraft of claim 5 , wherein the hydro-floats each include a reverse deadrise having one or more concavities in the portion of the hydro-floats that are beneath the waterline in stage one, the hydro-floats being in contact with the surface of the water in stage two, and spaced above the surface of the water in stage three.

11. A watercraft for three-stage operation, in a first stage the watercraft riding in the water as a boat, in a second stage the watercraft riding on the surface of the water, and in a third stage the watercraft traveling in ground effect above the water, the watercraft comprising:

a hydro-wing being formed by a combined hull and pair of wings, the combined hull and pair of wings having a bottom surface constructed and arranged to contact the water during the first stage, and a top surface opposite the bottom surface constructed and arranged to support a cockpit, and wherein a continuous ground effect surface is formed by the bottom surface of the combined hull and the pair of wings to maintain the watercraft in ground effect during the third stage wherein the hydro-wing is spaced a distance above the water and traveling in ground effect;

at least a single hydrofoil supported by the hydro-wing and constructed and arranged to contact the water in stage two; and

a pair of outboard hydro-floats supported on the bottom surface of the hydro-wing on a port and a starboard side thereof.

12. The watercraft of claim 11 , further comprising an articulating trim arm operatively connected to an elevator control supported by the hydro-wing, the articulating trim arm being constructed and arranged to contact the water during the third stage of operation, as desired, when the hydro-wing is traveling spaced above the water.

13. The watercraft of claim 11 , wherein the hydro-floats each include a reverse deadrise having one or more concavities in the portion of the hydro-floats that are beneath the waterline in stage one, the one or more concavities being constructed and arranged to create a positive turbulence as water passes by the one or more concavities and turns in a vortex to create additional lift of the hydro-wing, the hydro-floats further being in contact with the surface of the water in stage two, and spaced above the surface of the water in stage three.

14. The watercraft of claim 11 , wherein the at least a single hydrofoil comprises a forward hydrofoil supported on the forward portion of the hydro-wing, and an aft hydrofoil supported on the rear portion of the hydro-wing.

15. The watercraft of claim 14 , wherein the forward hydrofoil and the aft hydrofoil are movable between a first, in-use position where the forward and aft hydrofoils engage the water and a second, stored position where the forward and aft hydrofoils are in a stored position.

16. The watercraft of claim 11 , further comprising at least one rotational air propeller supported by the hydro-wing and constructed and arranged to effectuate turning and steering.

17. The watercraft of claim 16 , wherein the at least one rotational air propeller is movable between a forward and rear facing position.
