Abstract

Wakeboarding performance is improved using a vessel having an operator station located generally amidships, a vertical support unit fitted across a beam of the vessel near the operator station, and adjustable ballast. An upper portion of the vertical support is at a height substantially above a level of the operator station, and a container is onboard and proximate the starboard and port sides, wherein water from a body of water within which the vessel is operating is directed into the container for weighing down a stern of the vessel to provide the ballast so as to modify a wake created for a wakeboarder or the like being towed by the vessel using a tow rope attached to the upper portion of the vertical support.

Claims

1. A water sports vessel comprising:

an operator station located generally amidships between opposing starboard and port sides;

a vertical support unit fitted across a beam of the vessel proximate the operator station, the vertical support unit having an upper portion at a height substantially above a level of the operator station, the vertical support adapted for securing a tow rope thereto;

a tow rope receiver carried by the upper portion of the vertical support unit for attaching a tow rope thereto and towing a performer therefrom;

at least one container onboard the vessel and proximate the starboard and port sides thereof; and

an extractor positioned for directing water into the at least one container from a body of water within which the vessel is operating for weighing down a stern of the vessel so at to modify a wake created thereby;

wherein the at least one container comprises an enclosed container having an opening therein for venting air thereto; and

further comprising a valve operable with the opening for controlling air venting to the at least one container.

2. The vessel according to claim 1, wherein the at least one container extends aft amidships toward the stern.

3. The vessel according to claim 2, wherein the at least one container extends from only aft amidships.

4. The vessel according to claim 1, wherein a lower most portion of the at least one container is fitted generally at a waterline of the vessel when the at least one container is substantially empty of water.

5. The vessel according to claim 1, wherein the extractor comprises a water scoop positioned for extracting the water from the body of water as the vessel moves therethrough.

6. The vessel according to claim 1, wherein the extractor comprises a pump operable for enhancing the water extracting.

7. The vessel according to claim 6, wherein the pump is a two way pump.

8. The vessel according to claim 1, wherein the at least one container comprises at least one storage tank.

9. The vessel according to claim 8, wherein the at least one storage tank comprises generally rigid walls.

10. The vessel according to claim 1, wherein the at least one container comprises starboard and port containers.

11. The vessel according to claim 10, wherein each of the starboard and port containers comprise an elongated leg portion fitted beneath starboard and port quarter gunwales, respectively, of the vessel.

12. The vessel according to claim 11, wherein each of the starboard and port containers are generally L-shaped and include a second leg portion fitted along an inboard side of a transom of the vessel.

13. The vessel according to claim 1, wherein the vertical support unit comprises:

a first, generally vertical support attached to the starboard side;

a second, generally vertical support attached to the port side; and

a third support attached to the first and second supports, with the third support extending generally aft, upwardly above, and proximate the operator station, and wherein the third support is coupled to the first and second supports to provide the vertical support unit with a structural strength sufficient to withstand forces from towing a human performer behind the vessel by a rope attached to the tow rope receiver.

14. The vessel according to claim 13, wherein the third support comprises a generally U-shaped structure.

15. The vessel according to claim 1, wherein the vertical support unit comprises a generally U-shaped support structure.

16. The vessel according to claim 15, wherein the generally U-shaped support structure comprises:

a first U-shaped support structure fitted across the beam of the vessel at a point forward the operator station;

a second U-shaped support structure fitted across the beam of the vessel at a point aft the operator station and substantially above the level of the operator station; and

at least one rigid bar attached between the forward and aft U-shaped structures.

17. The vessel according to claim 1, further comprising a tow rope attached to the tow rope receiver.

18. The vessel according to claim 1, wherein the vertical support unit comprises a skeletal frame including a plurality of rigid vertical support members fitted to the starboard and port sides of the vessel at a location proximate the operator station.

19. A water sports vessel comprising:

an operator station located generally amidships between opposing starboard and port sides;

a vertical support unit fitted across a beam of the vessel proximate the operator station, the vertical support unit having an upper portion at a height substantially above a level of the operator station, the vertical support adapted for securing a tow rope thereto;

a tow rope receiver carried by the upper portion of the vertical support unit for attaching a tow rope thereto and towing a performer therefrom;

at least one container onboard the vessel and proximate the starboard and port sides thereof; and

an extractor positioned for directing water into the at least one container from a body of water within which the vessel is operating for weighing down a stern of the vessel so at to modify a wake created thereby;

wherein the at least one container comprises starboard and port containers; and

wherein each of the starboard and port containers comprise an elongated leg portion fitted beneath starboard and port quarter gunwales, respectively, of the vessel.

20. The vessel according to claim 19, wherein each of the starboard and port containers are generally L-shaped and include a second leg portion fitted along an inboard side of a transom of the vessel.

21. A water sports vessel comprising:

an operator station located generally amidships between opposing starboard and port sides;

a vertical support unit fitted across a beam of the vessel proximate the operator station, the vertical support unit having an upper portion at a height substantially above a level of the operator station, the vertical support adapted for securing a tow rope thereto;

a tow rope receiver carried by the upper portion of the vertical support unit for attaching a tow rope thereto and towing a performer therefrom;

at least one container onboard the vessel and proximate the starboard and port sides thereof; and

an extractor positioned for directing water into the at least one container from a body of water within which the vessel is operating for weighing down a stern of the vessel so at to modify a wake created thereby;

wherein the vertical support unit comprises a generally U-shaped support structure; and

wherein the generally U-shaped support structure comprises;

a first U-shaped support structure fitted across the beam of the vessel at a point forward the operator station;

a second U-shaped support structure fitted across the beam of the vessel at a point aft the operator station and substantially above the level of the operator station; and

at least one rigid bar attached between the forward and aft U-shaped structures.
