Rearward seating area 30 also includes an operator area 36 having at least one actuatable operator input for operating power source 28 and pontoon boat 10. Pontoon boat 10 also includes a collapsible canopy 38 pivotally coupled to railing 22. Canopy 38 is pivotable between a stored configuration (shown in FIG. 1) and a deployed configuration in which canopy 38 covers at least a portion of rearward seating area 30 and forward seating area 32. In embodiments, canopy 38 may comprise an upper frame fixedly coupled to railing 22. In other embodiments, canopy 38 may comprise a hard-shell cover or superstructure for deck 20.


Turning now to FIG. 2, deck 20 (see FIG. 1) is supported by a framework 40, which is connected to pontoons 12, 14, 16 using a plurality of brackets. In the embodiment shown, the plurality of brackets support framework 40 above a top surface of pontoons 12, 14, 16. Framework 40 includes a forward perimeter rail 42 positioned at bow end 24 of deck 20 and a plurality of transverse cross members 44, illustratively cross members 44a-o, arranged perpendicular to a longitudinal axis A of pontoon boat 10. Cross members 44 extend from a right or starboard side 46 of pontoon boat 10 to a left or port side 48 of pontoon boat 10. In the exemplary embodiment shown, cross members 44 are spaced apart from one another and are distributed along a longitudinal length of deck 20 of pontoon boat 10. It is contemplated, however, that cross members 44 may be grouped and arranged as the design of deck 20 requires. In embodiments, framework 40 may include more or fewer than cross members 44a-o.


Framework 40 also includes a split rearward perimeter rail 50, illustratively a starboard side rearward perimeter rail 50a and a port side rearward perimeter rail 50b, proximate stern end 26 of deck 20 of pontoon boat 10. In the exemplary embodiment shown, rearward perimeter rails 50a, 50b are positioned longitudinally rearward of an end of pontoons 12, 14. Accordingly, starboard side rearward perimeter rail 50a is supported by a plurality of support members 52, illustratively 52a-c, coupled to cross member 44o, and port side rearward perimeter rail 50b is supported by a plurality of support members 52, illustratively, 52d-f, coupled to cross member 44o. Positioned laterally intermediate rearward perimeter rails 50a, 50b is a power source support structure 54 coupled to middle pontoon 16 and configured to support power source 28.


Framework 40 also includes a starboard side perimeter rail 56 positioned on starboard side 46 of pontoon boat 10 and extending from the forward perimeter rail 42 to starboard side rearward perimeter rail 50a. Framework 40 also includes a port side perimeter rail 58 positioned on port side 48 of pontoon boat 10 and extending from forward perimeter rail 42 to starboard side rearward perimeter rail 50b. In the exemplary embodiment shown, deck 20 further includes a platform 60 (see FIG. 3) supported atop framework 40.


Turning now to FIGS. 3-5, pontoons 12, 14, 16 are shown in more detail. In the exemplary embodiment shown, middle pontoon 16 is arranged along longitudinal axis A (see FIG. 2) of pontoon boat 10 and outer pontoons 12, 14 and arranged laterally outward of middle pontoon 16. More specifically, outer pontoon 12 is positioned adjacent starboard side 46 of deck 20 of pontoon boat 10 and outer pontoon 14 is positioned adjacent port side 48 of deck 20 of pontoon boat 10. Outer pontoons 12, 14 are illustratively cylindrically shaped pontoons, and middle pontoon 16 is illustratively an elliptically shaped pontoon. More specifically, outer pontoons 12, 14 have a cylindrically shaped transverse cross-section, and middle pontoon 16 has an elliptically shaped transverse cross-section. As shown in FIGS. 1 and 4, pontoons 12, 14, 16 also include a longitudinally curved nose cone proximate bow end 14 of deck 20. In the exemplary embodiment shown, a vertically lowest point of each of the outer surfaces of pontoons 12, 14, 16 are co-planar, as indicated by plane P in FIG. 3. Plane P is tangential to the vertically lowest point of each of the outer surfaces of pontoons 12, 14, 16. In the illustrated embodiment, plane P is horizontal.


Pontoon boat 10 illustratively includes a plurality of chines configured to provide pontoon boat 10 with the handling characteristics of a hulled boat. More specifically, middle pontoon 16 includes a plurality of strakes or foils 62, illustratively a starboard foil 62a and a port foil 62b, coupled to an outer surface 15b (envelope 15b) of pontoon 16. Foils 62a, 62b are positioned on outer surface 15b of pontoon 16 adjacent the respective one of pontoons 12, 14. More specifically, foil 62a is positioned on the outer surface of pontoon 16 adjacent outer pontoon 12, and foil 62b is positioned on the outer surface of pontoon 16 adjacent outer pontoon 14. Foils 62 extend laterally outward from the outer surface of pontoon 16 to a distal end point. In the exemplary embodiment shown, foils 62 comprise an upswept chine. Accordingly, foils 62 have a generally triangular cross-section and extend further laterally outward than vertically downward from the outer surface of pontoon 16. It is contemplated, however, that foils 62 may comprise a differently shaped chine than shown. For example, foil 62 may comprise a reverse chine or a stepped chine. As illustrated in FIGS. 4-6, a forward end and a rear end of each of foils 62 are blunt and closed-off. It is contemplated, however, that either the forward end or the rear end of foils 62 may be open or comprise a hydrodynamic shape. In addition, the cross-section of each of foils 62 is generally constant as it extends from the forward end to a rear end. It is contemplated, however, that the cross-section of foils 62 may increase or decrease. For example, the cross-section of foils 62 may decrease such that foils 62 fade into the outer surface of pontoon 16 at either of the forward or rear end.


Each of outer pontoons 12, 14 also include a strake or foil 64, illustratively foils 64a, 64b, coupled to an outer surface 15a (envelope 15a) and an outer surface 15c (envelope 15c) of a respective one of pontoons 12, 14. More specifically, foil 64a is positioned on outer surface 15a of pontoon 12 adjacent middle pontoon 16. Similarly, foil 64b is positioned on outer surface 15c of pontoon 14 adjacent middle pontoon 16. Accordingly, foils 64 are positioned on the laterally inward sides of the respective one of pontoons 12, 14 and extend laterally inward to a distal end point. In the illustrated embodiment of FIG. 3, pontoon 12 comprises a center plane 74a, pontoon 14 comprises a center plane 74b, and pontoon 16 comprises a center plane 74c. Foil 64a is positioned on the outer surface of pontoon 12 such that an apex 65a of the foil 64a is on one side of the center plane 74a. Similarly, foil 64b is positioned on the outer surface of pontoon 14 such that an apex 65b of the foil 64b is on one side of the center plane 74b. Further in the illustrated embodiment of FIG. 3, foil 64a is positioned on outer surface 15a of pontoon 12 such that the entirety of the foil 64a is on one side of the center plane 74a. Similarly, foil 64b is positioned on outer surface 15c of pontoon 14 such that the entirety of the foil 64b is on one side of the center plane 74b. In the exemplary embodiment shown, foils 64 comprise a negative foil, or an extreme reverse chine oriented laterally inward. Accordingly, foils 64 have a generally triangular cross-section and extend further vertically downward than laterally outward from the outer surface of the respective one of outer pontoons 12, 14. It is contemplated, however, that foils 64 may comprise a differently shaped chine than shown. As illustrated in FIGS. 4-6, a forward end and a rear end of each of foils 64 are blunt and closed-off. It is contemplated, however, that either the forward end or the rear end of foils 64 may be open or comprise an hydrodynamic shape. In addition, the cross-section of each of foils 64 is generally constant as it extends from the forward end to a rear end. It is contemplated, however, that the cross-section of foils 64 may increase or decrease. For example, the cross-section of foils 64 may decrease such that foils 64 fade into the outer surface of the respective one of pontoons 12, 14 at either of the forward or rear end.


Referring specifically to FIG. 3, the lowest vertical extent or point of foils 64 of the respective one of outer pontoons 12, 14 are positioned vertically lower than an entirety of foils 62 of middle pontoon 16. More specifically, the distal end point of foil 64a, which is the vertically lowest point of foil 64a of outer pontoon 12, is positioned vertically lower than foil 62a of middle pontoon 16, as indicated by a gap 66a in FIG. 3. Similarly, the distal end point of foil 64b, which is the vertically lower point of foil 64b of outer pontoon 14, is positioned vertically lower than foil 62b of middle pontoon 16, as indicated by a gap 66b in FIG. 3. In the embodiment shown, gaps 66a, 66b are identical and comprise a distance of 2 inches to 3 inches. Illustratively, gaps 66a, 66b comprise a distance of approximately 2.48 inches. It is contemplated, however, that gaps 66a, 66b may be different from one another and that gaps 66a, 66b may comprise a distance greater or smaller than shown so long as the distance is nonzero. Illustratively, the distal end points of foils 64 of outer pontoons 12, 14 are co-planar with plane P, and foils 62 of middle pontoon 16 are spaced apart from and vertically above plane P.


Referring now to FIGS. 2, 6, and 7, foils 64 extend longitudinally along their respective one of outer pontoons 12, 14 for a length L1. Conversely, foils 62 extend longitudinally along middle pontoon 16 for a length L2. In the exemplary embodiment shown, length L2 is longitudinally longer than length L1. Accordingly, foils 62 of middle pontoon 16 extend longitudinally further than foils 64 of outer pontoons 12, 14. Illustratively, length L1 is approximately half of the length of length L2, and length L2 extends from proximate bow end 24 of deck 20 to stern end 26 of deck 20. In the exemplary embodiment shown, the start of foils 62, 62 are set back from bow end 24 of deck 20 as each of pontoons 12, 14, 16 includes a curved nose cone. It is contemplated, however, that lengths L1, L2 may be longer or shorter than shown.


Foils 62, 64 are configured and positioned on the outer surface of the respective one of pontoons 12, 14, 16 to improve the handling characteristics of pontoon boat 10. More specifically, foils 62, 64 are configured to provide handling characteristics (e.g., banking and planing characteristics) similar to a hulled boat. Foils 62, 64 also increase the stability of pontoon boat 10, especially when a heavy or powerful power source 28 is used and passengers seat themselves in forward seating area 32. In addition, foils 62, 64 cooperate to provide a three-point planning surface for pontoon boat 10 during operation thereof. More specifically, foils 64 provide lift for bow end 24 of pontoon boat 10, and foils 62 providing a stabilizing surface for stern end 26 of pontoon boat 10. Accordingly, foils 64 of pontoons 12, 14 in combination with foils 62 of pontoon 16 provide the “three” points of the planing surface for pontoon boat 10. In addition, foils 62, 64 assist with the high-speed performance of pontoon boat 10. For example, foils 64 provide a stabilizing surface which permit pontoon boat 10 to bank into a turn while the configuration of foils 62 slide sideways over the water.


Turning now to FIG. 8, another exemplary pontoon boat 10′ having a multi-chine configuration is shown. Because pontoon boat 10′ is similar to pontoon boat 10, reference characters in pontoon boat 10′ correspond to the same or similar reference characters in pontoon boat 10. Illustratively, pontoon boat 10′ includes outer pontoons 12′, 14′ and a middle pontoon 16′ positioned laterally intermediate outer pontoons 12′, 14′. In the exemplary embodiment shown, each of pontoons 12′, 14′, 16′ comprises an elliptically shaped pontoon.

As described above in connection with pontoon 10, foils 62 of middle pontoon 16″ extend longitudinally further than foils 64 of outer pontoons 12″, 14″.


Turning now to FIG. 10, another exemplary pontoon boat 10′″ having a multi-chine configuration is shown. Because pontoon boat 10′″ is similar to pontoon boat 10, reference characters in pontoon boat 10′″ correspond to the same or similar reference characters in pontoon boat 10. Illustratively, pontoon boat 10′″ includes outer pontoons 12′″, 14′″ and a middle pontoon 16′″ positioned laterally intermediate outer pontoons 12′″, 14′″. In the exemplary embodiment shown, middle pontoon 16″ comprises a cylindrically shaped pontoon and each of outer pontoons 12′″, 14′″ comprises a U-shaped hull.
