Abstract
A floatation device for a light-weight watercraft having a hull includes a frame member having a hull engaging member and float engaging member, and at least one float is held on the float engaging member. The floatation device is located below the hull of the boat. The hull engagement member is either a post for engagement with a scupper through the hull, or a strap for engagement with the gunwale of the watercraft. The float engagement member includes at least one member for engagement with the float. The float has a generally conical front end and a longitudinal hole therethrough for engagement with the member of the floatation engagement member.
Description
- The instant invention is directed to a floatation device for a light-weight watercraft, such as a kayak or a canoe.
- Light-weight watercraft include kayaks and canoes. Kayaks and canoes are most often self-propelled, for example by paddles. In use, they are typically laden with gear and/or may be equipped with a motor (for example see co-pending U.S. patent application Ser. No. 14/556,725 filed Dec. 1, 2014, incorporated herein by reference). When so loaded, portions of the watercraft may sink and make the craft off-balanced. The position and weight of any load may disrupt the craft's center of buoyancy resulting in issues with the propulsion and/or management/maneuvering of the watercraft.
- The instant invention solves the issues arising from the overburdening of a light-weight water craft.
- A floatation device for a light-weight watercraft having a hull includes a frame member having a hull engaging member and float engaging member, and at least one float is held on the float engaging member. The floatation device is located below the hull of the boat. The hull engagement member is either a post for engagement with a scupper through the hull, or a strap for engagement with the gunwale of the watercraft. The float engagement member includes at least one member for engagement with the float. The float has a generally conical front end and a longitudinal hole therethrough for engagement with the member of the floatation engagement member.
- For the purpose of illustrating the invention, there is shown in the drawings a form that is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.
-
FIG. 1 is an environmental (elevational) view of several embodiments of the instant invention mounted on a light weight watercraft. -
FIG. 2 is a top plan view of the embodiments shown inFIG. 1 . -
FIG. 3 is a side elevational view of an embodiment of the instant invention. -
FIG. 4 is a top plan view of the embodiment shown inFIG. 3 . -
FIG. 5 is an isometric view of the embodiment shown inFIG. 3 . -
FIG. 6 is another isometric view of the embodiment shown inFIG. 3 . - Referring to the drawings wherein like numerals indicate like elements, there is shown, in
FIG. 1 , a light-weight watercraft 10 illustrating several embodiments of the instant invention (discussed in greater detail below). Thewatercraft 10 is afloat, as indicated bywaterline 18. Additionally, the watercraft is burdened 20, for example, with a motor system (it being understood that the burden is not limited to the motor system, but may be any burden and the burden may be placed anywhere within the watercraft). - The
watercraft 10 may be any light-weight watercraft. For example, thewatercraft 10 may be a kayak (as shown) or a canoe. The watercraft generally includes ahull 12, astern 13, abow 14, agunwale 15, and a scupper 16 (seeFIG. 2 ). - The
watercraft 10 may include afloatation device 30. As shown inFIG. 1 , thefloatation device 30 is located toward thestern 13 and in proximity to theburden 20. The placement of thefloatation device 30, however, is not so limited. Instead, thefloatation device 20 may be placed anywhere along thehull 12 of thewatercraft 10. Thefloatation device 30 should be placed in proximity of the burden, so that the floatation device may offset the weight of the burden and righten the draft of the craft (i.e, level out the craft in the water). InFIG. 1 , for example the burden 20 (a motor and its battery) weighs down the stern, so that the stern sits lower in the water than the bow. Placement of thefloatation device 30 adjacent theburden 20 tends to righten the hull, so that the craft sits in a generally level relation to the waterline. In another example (not shown), theburden 20 may be place in (or near) the bow, then thefloatation device 30 should be place in proximity of that burden. - The
floatation device 30 may be located below thehull 12, or, in other words, may be below thewaterline 18. Thefloatation device 30 may be submerged below thewaterline 18. This placement adds little additional drag to thecraft 10. - The
floatation device 30 may have any configuration. The embodiments shown inFIGS. 1-6 are merely examples of certain ways to implement the invention. Thefloatation device 30, as illustrated, generally includes aframe member 32 having ahull engagement member 34 and afloat engagement member 36, and afloat 38 held on thefloat engagement member 36. - The
float 38 may be made of any buoyant material. The buoyancy of the float (s) 38 should be sufficient to offset the weight of theburden 20. Thefloat 38 may have any configuration. Thefloat 38, as shown, is generally cylindrical with a generally conical front end and a longitudinal channel therethrough. Thefloat 38, however, may have any configuration. As an example of an alternate configuration, thefloat 38 may be generally rectangular in shape with a tapered, e.g., triangular or beveled, (not shown), front (or leading) end, and a channel therethrough. There may be asingle float 38 or a plurality offloats 38. As shown, thefloats 38 number 4, but there may be any number of floats, for example 1, 2, 3, 4, or more. The channel through thefloat 38 is for receipt of theframe 32, as will be evident from the discussion below. - The
frame 32 may have ahull engagement member 34 and afloat engagement member 36. Theframe 32 may be made of any light-weight material. In the embodiment shown, theframe 32 is made from PVC tubing. - In the embodiment shown, the
floatation engagement member 34 generally comprises a generally rectangular system ofhorizontal members 40 with afloat 38, for example, slipped over each one of those members (i.e., via the channel through the float). The leading and trailing end ofmember 34 may be joined together, whereby the movement of thefloat 38 may be limited to their placement on themember 40. Thefloatation member 34 may be contoured to conform to the shape of thehull 12 or may be horizontal. - The
frame 32 may also have ahull engagement member 34. The hull engagement member is for securing thefloats 38 to thewatercraft 10 below thehull 12 or submerged below thewaterline 18. Thehull engagement member 34 may take any configuration, so long as the floats are held fast below the hull and/or submerged below the waterline. - In one embodiment, the
hull engagement member 34 may include avertical post 42 joined to thefloat engagement member 36. As shown, theframe 32 includes twovertical posts 42. Theseposts 42 extend upwardly and are adapted to slid throughscuppers 16. - In another embodiment, the
hull engagement member 34′ may include astrap 44. In this embodiment, thestrap 44 extends form onegunwale 15, over a surface of thefloat 38, to the opposinggunwale 15. The end ofstrap 44 may havebrackets 46. Thebracket 38 may have a hook shape for engaging the gunwales. Additionally, thestrap 44 may include a tightening mechanism (not shown), so that any slack instrap 44 may be removed. - The present invention may be embodied in other forms without departing from the spirit and the essential attributes thereof, and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention.
