DETAILED DESCRIPTION

(13) The present disclosure relates to exemplary mounting arrangements and other features of a watercraft. Although the disclosure primarily refers to a pontoon or pontoon boat, other watercraft and vehicles can benefit from the teachings herein. In this disclosure, like reference numerals designate like elements where appropriate and reference numerals with the addition of one-hundred or multiples thereof designate modified elements that are understood to incorporate the same features and benefits of the corresponding original elements.

(14) FIG. 1-7 illustrates a watercraft 20 according to an example. In the illustrated example, the watercraft 20 is a pontoon boat. The watercraft 20 includes a frame 24 and one or more pontoons or flotation devices 26. The frame 24 includes a main body 28 that extends axially between a forward end (i.e., bow) 30 and an aft end (i.e., stern) 32, and extends between opposed left and right sides (i.e., port and starboard) 34, 36. The frame 24 can be made of metal or metal alloy, for example, to provide rigidity. The frame 24 establishes a support 38 for mounting a deck 40 (shown in dashed lines in FIG. 3).

(15) In the illustrated example of FIGS. 1-3 and 6-7, each flotation device 26 is an elongated tube including a hollow interior to provide buoyancy in water during operation of the watercraft 20. Referring to FIGS. 1-3, the flotation device 26 can be made of a metal, metal alloy or a synthetic material such as a polymer (e.g., “polytube”), for example. In the illustrated example of FIGS. 1-3, the watercraft 20 includes three flotation devices 26 mounted to the frame 24. However, the watercraft 20 can include fewer or more than three flotation devices 26 to provide buoyancy, such as only two flotation devices 26.

(16) A cross section of the flotation device 26 can have a generally elliptical geometry, as illustrated by FIG. 3. One or more features 27, 29 can be defined along a circumference of the flotation device 26 to establish an interaction with the surrounding fluid during operation, which can improve maneuverability and stability of the watercraft 20.

(17) The watercraft 20 includes a mounting assembly 42 that mechanically attaches or otherwise fixedly secures the flotation devices 26 to the frame 24. The mounting assembly 42 includes a motor mount 44 mechanically attached to and extending from the aft end 30 of the frame 24 to mount an engine 46 (shown in dashed lines in FIG. 2) for propulsion.

(18) Referring to FIGS. 3-6, with continuing reference to FIGS. 1-2, the mounting assembly 42 includes a plurality of elongated brackets or mounts 48 mechanically attached to and extending downwardly from the frame 24. Each of the mounts 48 can be elongated to span at least partially between the forward and aft ends 30, 32 of the frame 24. Each mount 48 can be made of a metal or metal alloy, for example, and can be shaped to a predetermined geometry. Each mount 48 can be mechanically attached to the frame 24 by welding or with one or more fasteners, for example.

(19) As illustrated in FIG. 4B, each bracket 48 can have a generally S-shaped geometry including first and second flanges 48A, 48B extending outwardly from a bracket body 48C. The bracket body 48C can be dimensioned such that first and second flanges 48A, 48B are vertically spaced apart and extend substantially parallel to each other along a length of the bracket 48 to situate each flotation device 26 at a substantially constant elevation relative to the frame 24.

(20) The first flange 48A is mechanically attached to the frame 24. The second flange 48B is mechanically attached or otherwise secured to the respective flotation device 26. In the illustrated example of FIGS. 6 and 7, the second flange 48B is secured in an elongated groove or slot 31 defined by a main body 26A (see also FIG. 3) of a respective one of the flotation devices 26. The slot 31 can extend between opposed ends 26B, 26C of the flotation device 26, as illustrated by FIG. 7. Each flotation device 26 defines a pair of elongated slots 31 extending between opposed ends of the main body 26A, each of the slots 31 dimensioned to receive a respective one of the second flanges 48B to secure the respective flotation device 26, as illustrated by FIG. 6 (see also FIG. 3). The second flange 48B can be slideably received in the slot 31 to secure the flotation device 26 to the frame 24. An end bracket 50 (FIG. 6) can be mechanically attached to forward and aft ends of a pair of adjacent brackets 48 to secure the flotation device 26 to the frame 24 subsequent to the flotation device 26 slideably receiving each pair of the second flanges 48B in the slots 31. The slots 31 can improve the ability of the flotation devices 26 to expand and contract due to variation in thermal loading, which can reduce stress on the flotation devices 26 and respective mounts or brackets 48.

(21) Each pair of brackets 48 can be spaced apart from each other and can be dimensioned to situate a respective one of the flotation devices 26 at a predetermined elevation. In the illustrated example of FIG. 4, the mounting assembly 42 includes first, second and third sets of brackets 48-1, 48-2 and 48-3. Each of the second set of brackets 48-2 is dimensioned to establish a distance T1, and each of the first and third sets of brackets 48-1, 48-3 is dimensioned to establish a distance T2. As illustrated by FIG. 3, respective first, second, and third flotation devices 26-1, 26-2 and 26-3 are situated relative to a bottom of the frame 24. The first and third flotation devices 26-1, 26-3 each establish an elevation E1, and the second flotation device 26-2 establishes an elevation E2. The elevations E1, E2 can be the same or can differ. In the illustrate example of FIG. 3, the sets of brackets 48-1, 48-2 and 48-3 are dimensioned such that elevation E2 is greater than elevation E1.

(22) As illustrated by FIG. 8, bracket body 48C′ can be dimensioned such that a distance between first and second flanges 48A′, 48B′ differs along a length of bracket 48′, as illustrated by heights H1, H2. The second flange 48B′ slopes between opposed ends 48D′, 48E′ of the bracket body 48C′. The second height H2 is greater than the first height H1, and can be defined adjacent to an aft end 32′ of frame 24′ (shown in dashed lines). The different heights H1, H2 cause the opposed ends of the respective flotation device 26′ (shown in dashed lines for illustrative purposes) to be situated at different elevations relative to the frame 24′ to skew the elevation of the watercraft 20′ in the water between the forward and aft ends 30′, 32′. The relatively greater height H2 can increase buoyancy at an aft end 30′ of the watercraft 20′.

(23) FIGS. 9 and 10 illustrate a watercraft 120 according to another example. FIG. 9 illustrates flotation device 126 adjacent frame 124. FIG. 10 illustrates mounting assembly 142 including a pair of opposed brackets 148. Second flanges 148C are received in respective slots 131 defined by the flotation device 126. The flotation device 126 can define an elongated trough 152 that establishes a cavity between surfaces of the frame 124 and the flotation device 126. The trough 152 can extend between opposed ends of the flotation device 126 to receive one or more cables or conduits, for example.

(24) It should be understood that relative positional terms such as “forward,” “aft,” “upper,” “lower,” “above,” “below,” and the like are with reference to the normal operational attitude of the vehicle and should not be considered otherwise limiting.

(25) Although the different examples have the specific components shown in the illustrations, embodiments of this disclosure are not limited to those particular combinations. It is possible to use some of the components or features from one of the examples in combination with features or components from another one of the examples.

(26) Although particular step sequences are shown, described, and claimed, it should be understood that steps may be performed in any order, separated or combined unless otherwise indicated and will still benefit from the present disclosure.

(27) The foregoing description is exemplary rather than defined by the limitations within. Various non-limiting embodiments are disclosed herein, however, one of ordinary skill in the art would recognize that various modifications and variations in light of the above teachings will fall within the scope of the appended claims. It is therefore to be understood that within the scope of the appended claims, the disclosure may be practiced other than as specifically described. For that reason the appended claims should be studied to determine true scope and content.
