CLAIMS

What is claimed:

1. An artificial wave system comprising:

a mat positioned on a liner, the liner comprising a top surface, a bottom surface, a front end, and a back end opposite the front end, the front end of the liner configured to be proximate to a body of water, and the back end of the liner configured to be distal to the body of water;

a spray nozzle positioned along a front end of the liner, the spray nozzle configured to spray water from the body of water onto the mat and toward the back end of the liner; and

a ballast positioned on the top surface of the liner and spaced from the mat, wherein the mat, the top surface of the liner, and the ballast define a trench that extends away from the back end of the liner and toward the front end of the liner, wherein the trench is configured to guide water received from the spray nozzle toward the front end of the liner and into the body of water.

2. The artificial wave system of claim 1 , wherein the spray nozzle is in fluid communication with a personal watercraft attachment, the personal watercraft attachment configured to detachably couple to a jet of watercraft configured to receive water from the body of water.

3. The artificial wave system of claim 1 , wherein the ballast is configured to be inflated with water provided via a personal watercraft attachment detachably coupled to a propulsion system for a personal watercraft.

4. The artificial wave system of claim 1 , wherein the ballast comprises a first ballast and the trench comprises a first trench, the portable artificial wave system further comprising:

a second ballast positioned on the top surface of the liner and spaced from the mat, wherein the first ballast positioned along a first side of the mat and the second ballast positioned along a second side of the mat, wherein the second side of the mat, the second ballast, and the top surface of the liner define a second trench configured to guide the water from the spray nozzle toward the front end of the liner.

5. The artificial wave system of claim 4, further comprising:

a third ballast positioned proximate to the back end of the liner and spaced from the mat, wherein the mat, the third ballast and the top surface of the liner define a third trench that extends between the first trench and the second trench.

6. The artificial wave system of claim 1 , wherein the ballast comprises a first ballast, the portable artificial wave system further comprising:

a second ballast positioned beneath the bottom surface of the liner, wherein the second ballast is configured to level at least a portion of the mat in response to being filled with water.

7. The artificial wave system of claim 1 , wherein an outer surface of the mat comprises a lower coefficient of drag than the top surface of the liner.

8. A system, comprising:

a liner comprising a top surface and a bottom surface, wherein the bottom surface is configured to contact a ground surface beneath the liner;

a mat positioned on the top surface of the liner, the mat configured to receive water sprayed along a first direction by a spray nozzle to simulate a wave; and

a ballast positioned on the top surface of the liner and spaced from the mat, wherein the mat, the top surface of the liner, and the ballast define a trench configured receive water from the mat and guide the water along a second direction opposite the first direction.

9. The system of claim 8, wherein the spray nozzle is configured to receive water from a jet of a watercraft.

10. The system of claim 8, wherein the ballast is configured to be inflated with water pumped from a watercraft.

1 1 . The system of claim 8, wherein the ballast extends further away from the top surface of the liner than the mat.

12. The system of claim 8, wherein a front end of the liner is configured to be placed in a body of water and a back end of the liner is configured to be position on the ground surface, wherein the trench extends away from the back end of the liner and toward the front end of the liner to release water into the body of water at the front end of the liner.

13. The system of claim 8, wherein the mat, the ballast, or any combination thereof is integral to the liner.

14. The system of claim 8, wherein the mat, the ballast, or any combination thereof, is detachably coupled to the liner.

15. A method comprising:

positioning a liner on a beach surface so that a front end of the liner is located in or proximate to a body of water and a back end of the liner is located distally from the body of water;

positioning a mat on the liner;

positioning a ballast on the liner, the ballast spaced from an edge of the mat to define a trench between the mat and the ballast that extends toward the body of water; and

filling the ballast with water to retain the liner on the beach surface.

16. The method of claim 15, wherein filling the ballast with water further comprises: filling the ballast with water flowing from a jet of a watercraft;

17. The method of claim 15, further comprising:

connecting a personal watercraft attachment to a watercraft jet; and

spraying water onto the mat from a nozzle in fluid communication with the personal watercraft attachment.

18. The method of claim 15, further comprising positioning a spray nozzle at a front of the liner.

19. The method of claim 15, further comprising:

positioning a leveling ballast underneath the liner; and

filling the leveling ballast with water to cause at least a portion of the liner to become level.

20. The method of claim 15, further comprising:

unfolding the ballast, the liner, the mat, or any combination thereof.
