DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

Referring now initially to FIGS. 1-3, a preferred embodiment of the present invention is herein described, by way of example, by a water sports system 10 for improving aerial characteristics of a performance by a performer 12 using a water sports implement such as a wakeboard 14. The system 10 comprises a vessel 16 behind which the performer 12 is to be towed. The vessel 16 includes a bow 18, a stern 20, and an operator station 22 between opposing starboard and port sides 24, 26. A towing structure referred herein as a vertical support unit 100 is fitted to the vessel 16. The vertical support unit 100, as will be further described later in this section, includes an upper portion 102 at a height above the level of the operator station 22 and is adapted for securing a tow rope 28 thereto. The tow rope 28 is attached to the upper portion 102 of the vertical support unit 100 for towing the performer 12, as illustrated again with reference to FIG. 1. The system 10 further includes a ballast assembly 200 which includes starboard and port ballast tanks 202, 204 fitted onboard and only aft, preferably within only the stern 20, extending from the transom toward amidships of the vessel 16, unlike typical ballast systems which fully extend bow to stern. Alternate embodiments include a single ballast tank. An extractor 206 is fitted to the hull of the vessel 16 and is in fluid communication with the body of water 30 within which the vessel operates for forcing water 208 into the ballast tanks 204, 202 and weighting down the aft portion of the vessel 16, thus lowering the vessel and controlling a wake 32 created by the vessel.

It is to be noted that various sized vessels will have varying length ballast tanks for extending the tank from the transom area to toward amidships to provide a desirable wake. Simply weighting down the vessel stern only proximate the transom leads to excess plowing of the vessel and an undesirable wake. Further, displacement boats having ballast from stern to bow, typically do not permit planing, desirable in a sports towing vessel. As a result, a certain amount of planing is to be maintained. By extending the ballast tank as herein described, an effective vessel performance and wake is achieved. Without deviating from the invention, alternate embodiments are now herein described.

With regard to the vertical support unit 100, reference being made again to FIG. 2, the vertical support unit comprises a first relatively rigid vertical support structure 104 fitted to the starboard side 24 of the vessel 16, a second relatively rigid vertical support structure 106 fitted to the port side 26, and a generally horizontal bridging portion 108 extending between upper extremities of the first and second vertically extending support structures at a desired height above the level of the operator station 22. In a preferred embodiment, the vertical support unit 100 forms a skeletal frame, as illustrated again with reference to FIG. 2, which has a forward relatively rigid U-shaped support structure 110 and an aft relatively rigid U-shaped support structure 112, both fitted across the beam of the vessel 16. Longitudinally extending rigid bars 114 are attached between the forward and aft U-shaped structures. In a preferred embodiment, the bars are generally horizontal and parallel to the floor 34 of the vessel 16, as illustrated with reference again to FIG. 2, by way of example. Such a frame transfers forces generated by towing the performer to the gunwales, by way of example, and provides a rigid anchoring of the tow rope to the vessel for improving over typical single tow bar devices referred to earlier in this specification. For convenience in shipping, the bridging portion 108 is separable from the vertical support structures 104, 106 at connections 116. In general, the preferred embodiment is made from generally rigid aluminum tubing with elements of the unit 100 welded to each other to form a generally rigid skeletal frame.

In yet another embodiment, and with reference to FIG. 4, the vertical support unit 100 comprises a pylon 118 extending from the floor 34 of the vessel 16 and having an upper portion adapted for securing the tow rope 28 thereto. As illustrated again with reference to FIG. 2, and illustrated further with reference to FIG. 5, a tow rope connecting element 120 is attached to the upper portion of the vertical support unit 100, preferably to the horizontal bridging port 108 of the aft U-shaped support structure 112 for attaching the tow rope 28 thereto. The tow rope connecting element is mounted at a height 36 between 6' 3" and 7 feet above the floor 34 of the vessel 16, but it is expected that other heights will be selected by those skilled in the water sports arts. At this height 36, passengers on the vessel can comfortably walk under the U-shaped support structure 112 and the tow line 28 extending rearwardly from the boat for pulling the performer 12 while, at the same time, maintaining stability for the vessel 16 as the performer maneuvers around the vessel during the performance.

The skeletal frame is an improvement over the pylon by providing a generally more rigid unit 100 secured to four mounting locations 122 at sides 24, 26 of the vessel 16. In a preferred embodiment of the invention, the vertical support unit 100, as illustrated with reference again to FIG. 2, and to FIGS. 6-8, the system 10 further comprises attaching the vertical support unit 100 to vessel deck portions and gunwales 38, so as to permit the unit to be rotated when the vessel needs to pass underneath a bridge or into a boat house, by way of example. In a preferred embodiment, anchoring plates 124 are located about the operator station 22. The anchoring plates 124 each include a shaft 126 which terminates in a free end 128 having a through hole for receipt of a pivot pin or bolt 130. Removably and rotatably mounted on the anchoring shafts 126 are lower extremities 132 of the skeletal frame, as illustrated with reference again to FIGS. 7 and 8. As illustrated with reference to FIG. 11, an alternate arrangement includes mounting the plates 124 to the floor 34 of the vessel 16.

Trailering of the vessel is made more convenient with this rotating feature. In the event the overall height of the unit 100 needs to be reduced for trailering, for example, the unit 100 is rotatable to a position 134 shown in dotted lines in FIG. 6 or is removable entirely from the vessel 16. As illustrated again with reference to FIGS. 7 and 8, the pin or bolt 130 is removed from the appropriate anchoring plates 124 for rotating the unit 100 onto the forward deck of the vessel or aft at the convenience of the operator.

In addition, it is convenient to use portions of the unit 100 to stow various pieces of equipment such as a life vest 40 or wakeboard 42 and other equipment as illustrated with reference again to FIG. 6 and FIG. 9. Further, the convenient mounting of stereo speakers is also accomplished. Such equipment is also conveniently stowed out of the way when unit 100 is in the erect position 136 as earlier described with reference to FIGS. 1 and 2.

As illustrated with reference to FIG. 10, a clear line of sight is provided for individuals sitting in the seats 44 so as not to interfere with the steering of the vessel 16 or the maneuvering of passengers onboard. As illustrated, by way of example with reference to FIGS. 11-13, various embodiments for the unit 100 of the present invention are possible without deviating from the intent and value of the present invention.

As illustrated with reference again to FIGS. 2-3, and to FIG. 14, a preferred embodiment of the system 10 and the ballast assembly 200, a lower most portion 210 of each of the ballast tanks 202, 204 is preferably fitted at the waterline 212 of the vessel 16 when the tanks are empty, typically the floor 34 for towing vessels as herein described.

In preferred embodiments of the ballast tanks 202, 204 and with reference again to FIGS. 3 and 14, the ballast tanks are enclosed and each have an opening arranged through vent lines 214, 216 for venting air into and out of each of the enclosed tanks 202, 204 respectively. Further, an air control valve 218 is within easy reach by the vessel operator for manually controlling air venting to each of the ballast tanks. It is anticipated that electrically, pneumatically or hydraulically operated control valves may be appropriate. The extractor 206, earlier described, includes a water scoop 220 positioned below the water line 212 and on the hull 46 of the vessel 16 for extracting the ballast water 208 from the body of water 30 as the vessel 16 moves through the body of water and delivering the ballast water 208 through a water intake line 221 connected between the scoop 220 and ballast tanks 202, 204. In an alternate embodiment, a two way pump 222 is placed within the line 221 and used for enhancing the extracting and dumping of the ballast water 208. Further, a shut off valve 223 is fitted within the line 221. As illustrated again with reference to FIGS. 2 and 3, the ballast tanks 204, 208 comprise starboard and port enclosed ballast tanks wherein each of the starboard and port enclosed ballast tanks comprises a generally L-shaped tanks having a first elongated leg 224 fitted beneath quarter gunwales 26 of the vessel 16 and a second leg 228 fitted along an inboard side of the transom 230.

As illustrated with reference again to FIG. 3, intermediate of the stern 20 and bow 18 is the operator's seat 45 within which the operator sits to control steering while viewing instruments. The air control valve 218 is within easy reach of the operator.

As illustrated again with reference to FIG. 14, the inlet line 221 leads to a water scoop 220 which collects the ballast water 208 as the vessel 16 is moved forward through the body of water 30. The water 208 collected in the scoop 220 is fed through the intake line 221 upon proper positioning of the valves 218, 223. If the shut off valve 223 is closed, no water 208 will be allowed to be fed into ballast tanks 202, 204. In addition, water 208, if already in ballast tanks 202, 204 will not be allowed to leave the tanks. However, if the water 208 is to be introduced into ballast tanks 202, 204, the shut off valve 223 must be opened and in addition, the respective air line control valve 218, independently controlling each of the air lines 214, 216 must be opened to allow air to escape from the ballast tanks as the water is being scooped up and fed into the tanks. Thus, if the air line control valve 218 is open, water 208 will be forced into ballast tanks 202, 204 as the boat is moving forward until the ballast tanks are full or the valves are closed. Excess water is forced through the air lines 214, 216 past the air line control valve 218 as one indication that the tanks are full. Alternatively, water level indicators 232 are used. Additionally, tank overflow tubes 234 fitted with one way check valves 236 deliver excess water overboard, as illustrated again with reference to FIG. 14. The overflow tubes 234 limit the maximum pressure in the tanks to a maximum static head. The check valves 236 stop air from flowing back in the tanks when the air control valve 218 is closed.

To remove the water 208 from the tanks 202, 204, the vessel comes to a stand still in a preferred method of dumping the ballast water. The shutoff valve 223 is then opened, with the opening of the air control valve 218 for allowing air into the air lines 214, 216. Through the forces of gravity, the water 208 flows out of the tanks 202, 204 through the intake line 221 and out through the opened shutoff valve 223 to the surrounding body of water 30.

Since the operator sitting in seat 45 has easy access to both valves 218, 223, the amount and shape of the wake 32, illustrated with reference again to FIG. 1, produced by the vessel 16 can be precisely controlled by the operator. By selectively shifting the ballast water 208 into and out of the tanks 202, 204, the wake 32 is produced to a controlled degree for optimum and desirable wakeboarding.

Accordingly, many modifications and other embodiments of the invention will come to the mind of one skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed, and that modifications and embodiments are intended to be included within the scope of the appended claims.
