Additional and/or alternative features, aspects, and advantages of embodiments of the present technology will become apparent from the following description, the accompanying drawings, and the appended claims.
For a better understanding of the present technology, as well as other aspects and further features thereof, reference is made to the following description which is to be used in conjunction with the accompanying drawings, where:
A watercraft 50 in accordance with one embodiment of the present technology is shown in
The boat 50 has a deck 60 and a hull 70. The deck 60 is disposed on the hull 70, and is supported thereby. The deck 60 has an upper surface 64 for supporting occupants, as well as accessories and accommodations of the boat 50 including seats 52 and a command console 54. It is contemplated that the deck 60 could include multiple levels and/or other seating or other accessories integrated therein. The deck 60 defines a longitudinal center plane 62 that defines a left side and a right side of the boat 50.
The hull 70 includes three pontoons connected to the deck 60: a left pontoon 72, a center pontoon 74 and a right pontoon 76. As will be described below, it is contemplated that in other embodiments, the hull 70 may have a different number of pontoons. The left pontoon 72 is disposed on the left side of the boat 50, the right pontoon 76 is disposed on the right side of the boat 50, and the center pontoon 74 is disposed centrally along a width of the boat 50 such that a center plane 75 (shown in
The boat 50 has a side structure 90 surrounding at least part of the deck 60 and extending upwardly therefrom. In the present embodiment, the side structure 90 is a barrier structure 90. It is contemplated that that in some embodiments, the side structure 90 could be gunnels of the boat 50 or another type of structure. The barrier structure 90 is located near a periphery of the boat 50 (as defined by the deck 60). The barrier structure 90 generally covers the front, left and right sides of the deck 60. It is contemplated that, in other embodiments, the barrier structure 90 could surround the deck 60 completely. The boat 50 further includes a bimini 92 connected to the barrier structure 90.
At a rear end thereof, the boat 50 has a platform 94. The platform 94 provides, beyond the barrier structure 90, additional space at the rear of the boat 50 which can facilitate access to the water.
As best seen in
The outboard engine 58 is operatively connected to a steering wheel 56 that is disposed on a command console 54, such that the boat 50 can be steered by causing the outboard engine 58 to pivot about a steering axis. It is contemplated that in other embodiments, the boat 50 could be steered by causing movement of one or more rudders. The outboard engine 58 is further operatively connected to a throttle 57 that is also disposed on the command console 54. The throttle 57 is configured to control the operation of the outboard engine 58 so as to control a speed of the boat 50.
The left and right pontoons 72, 76 are substantially the same. The center pontoon 74, while having some similarities with the left and right pontoons 72, 76, differs therefrom as it is configured to have the outboard engine 58 connected thereto. Notably, as will be described in greater detail below, the center pontoon 74 has a deflector 200.
With reference to
The center pontoon 74 is sized so as to extend, in the longitudinal direction, along an entirety of the length of the boat 50. The center pontoon 74 has a front portion 100, an intermediate portion 102 and a rear portion 104. Additionally, the center pontoon 74 has, extending upwardly from the front and intermediate portions 100, 102, a left connecting structure 108a and a right connecting structure 108b. The center pontoon 74 is connected to the deck 60 by the left and right connecting structures 108a, 108b. The center pontoon 74 also a left strake 109a and a right strake 109b (best seen in
The front portion 100 has a hydrodynamic shape that can assist in reducing drag induced by the center pontoon 74 during movement of the boat 50, particularly in the forward direction. The front portion 100 is hollow. It is contemplated that the front portion 100 could contain closed-cell foam.
The intermediate portion 102, which has a generally hollow cylindrical shape, has a storage compartment 110 and a fuel tank compartment 120.
The storage compartment 110 is longitudinally delimited by a front wall 111 and a wall 121 (
The fuel tank compartment 120 is longitudinally delimited by the wall 121 and a wall 131 (
The rear portion 104, which is also hollow, has a rear chamber 130 that is longitudinally delimited by the wall 131 and a rear wall 140. The rear chamber 130 communicates with the fuel tank compartment 120 by an aperture 133 defined in the wall 131. In some instances, the rear chamber 130 could additionally communicated with the storage compartment 110. A bilge pump 132 is disposed in the rear chamber 130, and is configured to pump fluid out of the rear chamber 130 and out of the central pontoon 74.
The rear portion 104 defines, at a top of the rear chamber 130, an aperture 134 closed by a cap 135. The user can access the rear chamber 130 (e.g., to access the bilge pump 132) via the aperture 134 by removing the cap 135.
Above the rear chamber 130, the rear portion 104 has left and right upper walls 139a, 139b. The left and right upper walls 139a, 139b extend from rear ends of the connecting structures 108a, 108b, respectively, to the rear wall 140. Parts of the left and right upper walls 139a, 139b also extend laterally outward.
The rear portion 104 also has a rear surface 142. More specifically, the rear wall 140 has the rear surface 142. As best seen in
The rear surface 142, which is generally flat, defines four apertures 144. It is contemplated that in some embodiments, the rear surface 142 could define more or less than four apertures 144. Each one of the four apertures 144 is configured to receive a fastener 146 therein (only two fasteners 146 shown in
In the illustrated embodiment, the mounting bracket 96 is connected to the rear surface 142 of the center pontoon 74 by the fasteners 146. It is contemplated that in other embodiments, the mounting bracket 96 could be connected to the rear surface 142 differently, and that the fasteners 146 could be omitted.
With reference to
The left and right panels 150a, 150b are mirror images of one another. Thus, only the left panel 150a will be described in detail herein.
The left panel 150a has a front section 152 that extends laterally and a rear section 154 that extends generally longitudinally. The front and rear sections 152, 154 generally form an L-shape. The front section 152 is sized to have its laterally outward end connect to a connecting structure 108b of the left pontoon 72, and to have its laterally inner end connect to the left upper wall 139a of the center pontoon 74. The rear section 154 is configured to connect to the upper left wall 139a, and as such, the orientation of the rear section 154 is generally aligned with the orientation of the upper left wall 139a. Thus, the rear section 154 extends longitudinally rearward and partially laterally outwardly from the front section 152. Furthermore, the rear section 154 is tapered in the longitudinal direction, such that a width of the rear section 154 increases as the rear section 154 extends longitudinally rearward.
The left and right panels 150a, 150b can assist in reinforcing the upper left and right walls 139a, 139, which can, during movement of the boat 50, be subjected to high stresses due to forces of water applied against the upper left and right walls 139a, 139.
With continued reference to
The deflector 200 is sized such that the deflector 200 extends longitudinally beyond the mounting bracket 96. In the illustrated embodiment, the deflector 200 also extends longitudinally beyond the front surface of the outboard engine 58. It is contemplated that in other embodiments, the deflector 200 could be longitudinally shorter. For example, the deflector 200 could be configured to extend so as to only extend beyond part of the mounting bracket 96. The deflector 200, which also extends in the vertical direction, is sized to extend beyond a top of the rear wall 140 and beyond a top of the mounting bracket 96. It is contemplated that the deflector 200 could be vertically shorter. For example, the deflector 200 could be configured to only extend until the top of the rear wall 140.
The deflector 200 defines a lower gap 202, such that the deflector 200 includes a left deflector portion 204a and a right deflector portion 204b. As will be described below, the lower gap 202 is configured to receive part of the outboard engine 58 therethrough. In some embodiments, the lower gap 202 could be omitted.
The left deflector portion 204a extends along the left lateral side 78a of the rear surface 142, whereas the right deflector portion 204b extends along the right lateral side 78b of the rear surface 142. The left and right deflector portions 204a, 204b are generally symmetrical about the center plane 75 of the center pontoon 74. As such, only the left deflector portion 204a will be described in detail herein. Corresponding features on the right deflector portion 204b have been labeled with the same reference numerals in the accompanying Figures.
The left deflector portion 204a has an upper left segment 210 and a lower left segment 212.
The upper left segment 210, at least part of which extends longitudinally rearward and laterally outward from the rear surface 142, includes an upper planar section 220, an angled section 222 disposed vertically below the upper planar section 220, and a lower planar section 224 disposed vertically below the angled section 222.
The upper planar section 220 is an extension of the left upper wall 139a, and as such, the upper planar section 220 and the left upper wall 139a are generally oriented in the same direction. Thus, the upper planar section 220 extends longitudinally rearward and laterally outward. The upper planar section 220 extends vertically such that a top thereof is disposed vertically higher than the top of the rear wall 140 and higher than the top of the mounting bracket 96. A bottom of the upper planar section 220 is disposed below the top of the rear wall 140. It is contemplated that the vertical span of the upper planar section 220 could vary from one embodiment to another. For example, in some instances, the top and/or the bottom of the upper planar section 220 could be generally aligned with the top of the rear wall 140.
The angled section 222 extends downwardly and laterally inwardly from the bottom of the upper planar section 220. More specifically, the angled section 222 is oriented such that a bottom thereof is disposed laterally inwardly from a top thereof. The angled section 222 has a triangular shape. It is contemplated that in other embodiments, the angled section 222 could have another shape. The configuration of the angled section 222 is such that when the boat 50 is moving in a forward direction, water flowing over the angled section 222 is deflected laterally outward and vertically downward.
The lower planar section 224 extends downwardly from the angled section 222. Due to the orientation and shape of the angled section 222, the lower planar section 224 has a trapezoidal shape. It is contemplated that in other embodiments, the lower planar section 224 could have another shape. The lower planar section 224 is configured to generally follow a profile of the left lateral side 78a. The profile of the left lateral side 78a along the lower planar section 224 is generally linear. Thus, the lower planar section 224 is also linear. The lower planar section 224 extends from the rear surface 142 generally orthogonally. It is contemplated that in some embodiments, the lower planar section 224 could extend from the rear surface 142 at an angle.
The lower left segment 212, which extends below the lower planar section 224, is configured to further follow the profile of the left lateral side 78a of the rear wall 140. As can be seen in
When the outboard engine 58 is connected to the center pontoon 74, since a lowermost point of the outboard engine 58 is disposed vertically below a lowermost point of the center pontoon 74, part of the outboard engine 58 extends through the lower gap 202. Additionally, as best seen in
When the boat 50 is moving in forward direction and/or accelerating, water flow into the longitudinal space 59 is limited by the presence of the deflector 200. Since the deflector 200 extends longitudinally between the rear surface 142 and the front of the outboard engine 58, water that would otherwise flow into the longitudinal space 59 is deflected away from the longitudinal space 59 by the deflector 200.
With reference to
In the boat 350, the central pontoon 74 has been replaced by a center pod 374. The center pod 374 is centered along the width of the boat 350, and only extends longitudinally along a relatively short portion of the length of the boat 350. The center pod 374, which is hydrodynamically shaped, has the outboard engine 58 mounted thereto via the mounting bracket 96. The center pod 374 has the deflector 200.
With reference to
The boat 450 has two outboard engines 58 and two mounting brackets 96. Additionally, the outboard engines 58 are connected to the left and right pontoons 72, 76 instead of the center pontoon 74. Furthermore, the left and right pontoons 72, 75 each have a deflector 200, whereas the center pontoon 74 does not have a deflector 200.
Modifications and improvements to the above-described embodiments of the present technology may become apparent to those skilled in the art. The foregoing description is intended to be exemplary rather than limiting. The scope of the present technology is therefore intended to be limited solely by the appended claims.
The present application claims priority to U.S. Patent Application No. 63/513,687, filed Jul. 14, 2023, which is incorporated by reference herein in its entirety.
