BACKGROUND OF THE INVENTION
This invention relates to a hybrid running surface boat, and in particular to a boat having a combination of pontoons and a hull structure.
Boating has become an increasingly popular form of recreation, leisure and platform for water sports. One type of boat, namely, pontoon boats, which have two or more longitudinally extending flotation devices with buoyancy sufficient to float itself as well as a deck, seats, and other boat equipment attached thereto as well as passengers, have also seen a rise in popularity. Pontoon boats provide an economical way to provide a large deck area accommodating many passengers as well as a smooth ride. Pontoon boats are particularly suited for inland lakes and rivers that do not have large waves.
Pontoon boats have become increasingly more elaborate with many convenience features as well as increased power. Pontoon boats are now offered with sufficient engine capacity to pull one or more water skiers or wake board riders; however, the wake produced by a traditional pontoon boat lacks the distinct and high crest that is generated by single hull ski boats and desired by skiers and wake board riders, especially by those who are advanced in the sport.
Accordingly, it is an object of the present invention to provide a boat having a hybrid running surface, that is, one having a combination of pontoons and a hull profile to provide the smooth ride and large deck area of a pontoon boat, yet offering improved wake characteristics for skiing and wake boarding.

The exemplification set out herein illustrates embodiments of the invention, and such exemplifications are not to be construed as limiting the scope of the invention in any manner.
DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings, which are described below. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. The invention includes any alterations and further modifications in the illustrated devices and described methods and further applications of the principles of the invention, which would normally occur to one skilled in the art to which the invention relates.
Now referring to FIG. 1, a pontoon boat is shown, generally indicated as 10. Pontoon boat 10 includes a deck 12; a railing 13 extending around the outer periphery of deck 12; a seating arrangement, generally indicated as 14; an outboard motor 16; and an adjustable canopy 18, all of which may be of a variety known to one skilled in the art. Pontoon boat 10 also includes a hybrid running system in accordance with the subject invention, generally indicated as 20, to provide flotation of boat 10 in water while either stationary or in motion.
Now referring to FIGS. 2-4, hybrid running surface 20 includes two outer pontoons, 22 and 24, and a combination middle pontoon, 26 and hull section/portion 28. In the embodiment shown, hull portion 28 is attached to and mounted to the rear of pontoon 26, which is located intermediate between outer pontoons 22 and 24. Pontoons 22, 24 and the front portion of pontoon 26 are manufactured in accordance with known methods for constructing pontoons. Furthermore, the pontoons and hull portion 28 are constructed from known suitable materials for pontoon and boat construction including, but not limited to metals such as aluminum, steel, or stainless steel; composite materials such as fiberglass, or suitable plastic polymers. In the embodiment shown, each of the pontoons 24-26 has a tapered front portion 30 for facing and cutting into the water. In addition, pontoons 22 and 24 have curved or angled aft ends 32 that extend farther backward along the outer edges 33a than towards the inner portions 33b (as best shown in FIG. 3) to accommodate hull portion 28 and facilitate water flow.
It should further be appreciated that deck 12 is mounted to pontoons 22-26 and hull 28 using conventional methods.
Combination pontoon 26 and hull portion 28 are attached to one another at a junction 34. Hull portion 28 has a varied width and in the embodiment shown, is widest towards its aft end 36 and narrowest at a front end 38 where it is attached to pontoon 26. This configuration serves a joint purpose in that it transitions via attachment at forward end 38 to pontoon 26 while maintaining a wider aft end to produce the desired wake characteristics. Furthermore, in this embodiment, hull portion 28 does not extend as far below deck 12 as pontoons 22-26 do (see FIG. 4). It should be appreciated that at juncture 34, a sharp transition in height between hull portion 28 and pontoon 26 may be made or hull portion 26 may be gradually tapered downward to meet at the same depth or distance from deck 12 as the bottom of pontoon 26 extends. It should be appreciated that the attachment of hull 28 to pontoon 26 may be made by welding or other known means.
Also, in the embodiment shown in FIG. 4, hull portion 28 has a generally V-shaped or tapered cross-section being narrower at the bottom than towards the top. In addition, hull portion 28 includes two extension portions 40 for riding and wave characteristics. The remaining bottom of hull portion 28 is tapered down to a ridge 42 extending along a midline thereof.
Now referring to FIGS. 5 and 6, another embodiment of a pontoon boat is shown, generally indicated as 110. Pontoon boat 110 is similar in many respects to pontoon boat 10 and includes a deck 112; a railing 113 extending around the periphery of deck 112; a seating arrangement, generally indicated as 114; and a hybrid running surface, generally indicated as 120. Pontoon boat 110 includes pontoons similar to that of pontoon boat 10, but has a modified hull portion 128. Hull portion 128 does not have extension portions along the bottom ends, but does include a middle ridge 142 extending along a midline thereof. Furthermore, the aft end of hull portion 128 may extend farther downwardly from deck 112 than pontoon 122 or any of the other pontoons (not shown).
Referring now to FIGS. 7-15, another embodiment of a hybrid running surface is shown generally indicated as 20, with the pontoon boat removed for clarity, but a deck 212 shown in phantom lines.
Hybrid running surface 220 includes two outer pontoons 222 and 224, a middle pontoon 226, and a hull section/portion 228. Pontoon portions 222, 224, and 226 are manufactured in accordance with known methods for constructing pontoons. The materials used are similar to pontoons 22, 24, and 26 discussed above. Also, each pontoon 222, 224, and 226 includes a respective nose 222a, 224a, and 226a, which may curve or turn upward as best shown in FIGS. 7 and 11 to enhance travel through water. Additionally, in the embodiment shown, pontoons 222 and 224 each include a pair of extensions 225a and 225b that run longitudinally along the pontoons from noses 222a and 224a to the rear thereof. Extensions 225a, 225b have a generally triangular cross-section and are spaced apart towards the bottom of the pontoons (as best shown in FIGS. 7 and 9) to enhance stability and performance.
From FIG. 12, it can be seen that the rear end of pontoons 222 and 224 are flush with the back end of hull 228. Middle pontoon 226, though, has a rear extended portion 227.
Regarding hull portion 228, a bottom 244 of hull portion 228 is approximately flush with pontoons 222, 224, and 226 as shown in FIG. 9. Additionally, hull portion 228 includes two spaced apart sloping surfaces 246a and 246b on opposite sides of middle pontoon 226 and extending to respective outer pontoons 222 and 224. It should be appreciated that sloping surfaces 246a, 246b enhance pushing water down and beneath bottom surface 244 of hull portion 228 to enhance the wake characteristics behind the boat. At the rear of hull portion 228, a back panel 248 of the hull portion inclines extending outwardly on each side from pontoon 226 as best shown in FIG. 8 so that the middle of back panel 248 extends farther rearwardly, than the outer ends. Referring to FIG. 13, it can be seen that the top of hull portion 228 includes a panel 249 on each side of pontoon 226 to enclose hull structure 228. Referring now to FIGS. 14 and 15, hull portion 228 may include an internal support or stiffening structure, generally indicated as 250, which in the embodiment shown includes longitudinal members 252 and a plurality of cross members 254. Hull portion 228 may be welded to pontoons 222, 224, and 226, where they abut, or other known joining or fabrication methods may be employed. In this embodiment, hull portion 228 is located at approximately the rear % portion of the boat structure, with the upper forward portion of sloped portions 246a and 246b extending farther to the front of the craft.
Now referring to FIGS. 16-21, yet another alternate embodiment hybrid running surface for a boat is generally indicated as 320. Hybrid running surface 320 is mounted to a deck 312 and in the embodiment shown, includes outer pontoons 322 and 324 and a middle pontoon 326 running longitudinally beneath deck 312 and spaced apart from one another. Hybrid running surface 320 also includes a combination hull portion 328 that is attached to and at least partially surrounds a portion of middle pontoon 326 as best shown in FIGS. 16-17.
As shown in FIGS. 20 and 21, outer pontoons 322 and 324 do not extend to the rear deck 312, but rather are cut short thereof. In one embodiment, outer pontoons 322 and 324 include an angled rear end 332. Angled rear end surfaces 332 includes an outer rear edge 333a and an inner rear edge 333, as best shown in FIG. 20. In the embodiment shown in FIG. 20, outer rear edge 333a extends rearwardly further along deck 312 than does inner rear edge 333b. As with other hybrid running surfaces discussed above, pontoons 322, 324 and 326 may include extensions 325a and 325b as best shown in FIG. 21.
Regarding middle pontoon 326, it extends further rearwardly than either of the outer pontoons (322 or 324) or combination hull portion 328 as best shown in FIGS. 16-19. Hull portion 328 is joined with middle pontoon 326 at junction 334 (FIGS. 20 and 21). Hull portion 328 further includes angled side surfaces 345 extending rearwardly and outwardly from junction 334. As best shown in FIGS. 16-19, hull portion 328 further includes a planar surface 341 connecting the hull portion to middle to pontoon 326 and a sloped surface 343 extending upward from surface 341.
As should be appreciated by one skilled in the art, when hybrid running surface 320 is in motion in a body of water, hull portion 328, the pontoons, and the spaces between middle pontoon 326 and respective outer pontoons 322 and 324, allow hybrid running surface 320 to produce good wake characteristics in the body of water in which it is being propelled through.
While the invention has been taught with specific reference to these embodiments, one skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the invention. For example, it is possible to have the rear part of the hull portion extend out even wider than shown so that its width equals or exceeds the width between the outer pontoons. Additionally, other changes may be made in the shape of the hull to enhance the wake characteristics. The described embodiments are to be considered, therefore, in all respects only as illustrative and not restrictive. As such, the scope of the invention is indicated by the following claims rather than by the description.
