## Background
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates generally to personal watercraft apparatus and, more particularly, to a multi-purpose, collapsible personal watercraft having plural propulsion means and which is suitable for fishing.
Description of the Prior Art
The use and design of conventional personal watercraft apparatus is well known. A problem which still exists, however, is that conventional personal watercraft apparatus are generally a fixed size and optimized for only one thing, speed. A boater who enjoys riding a personal watercraft and also enjoys fishing is often required to have separate boat just for fishing because the personal watercraft is not suited for fishing. Further, even though they are generally smaller than conventional boats, personal watercraft are often no easier to transport that larger fishing boats and/or speed boats. Thus, there remains a need for a multi-purpose personal watercraft that is collapsible when not in use to enable it to more easily stored and transported. It would be helpful if such a multipurpose personal watercraft included multiple configurations employing discrete propulsion mechanisms. It would be additionally desirable for such a multipurpose personal watercraft to include a dual steering system for enabling control of a plurality of propulsion/navigation devices.
The Applicant's invention described herein provides for a multipurpose personal watercraft adapted to provide a easily transported boat structure that can be customized with floats, a rudder and/or propulsion devices. The primary components in Applicant's multi-purpose personal watercraft are a base frame and opposing side floats. When in operation, the multi-purpose personal watercraft enables a user to deploy a single watercraft in various configurations for various purposes. As a result, many of the limitations imposed by prior art structures are removed.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings and in particular FIGS. 1, 2, 3, 3A, 4, 5, 6, 7, 8, and 9, a multi-purpose personal watercraft 100 is shown having a base frame 110 selectively integrated with two opposing side floats 120. The base frame 110 defines a watercraft base having a deck side 111, hull side 112, selectively foldable side extensions 113 and a removable aft floor board 114. Each of the opposing side floats 120 defines a mirror image curved float body having an attachment plate 121. The respective side floats 120 are each selectively attachable individually, either along the starboard edge of the hull side 112 of the base frame 110 or the port edge of the hull side 112 of the base frame 110, depending on the floats 120. It is contemplated that when the respective side floats 120 are in place on the base frame 110, their respective attachment plates 121 converge with one another and are secured together through the interlock of a plurality of teeth 121′ that extend from each respective attachment plate 121. Accordingly, when in use, the side floats 120 form the multi-purpose personal watercraft's 100 U shaped hull.
Advantageously, because the side floats 120 attach individually to the base frame, either may be replaced or repaired as needed, without having to replace both.
In the preferred embodiment, the side floats 120 are secured to the base frame 110 through a plurality of float wells 122 on the top surface of the side floats 120 that each correspond to a flange that extends from the hull side 112 of the base frame 110 and frame wells 110′ on the side surface of the base frame that each correspond to a flange 122′ that extends from the side floats 120. It is contemplated, however, that in alternate embodiments, the side floats 120 may be secured to the base frame 110 through any conventional attachment device that would allow the side floats 120 to be held in a position flush against the surface of the hull side 112 of the base frame 110.
In one embodiment, each side float 120 includes a float enhancement body 123 sized to run along the length of the side float 120. The float enhancement body 123 is selectively attachable to the bottom of the side float 120 and smoothes the transition between the base frame 110 and the attached side float 120 on the underside of the multi-purpose personal watercraft 100.
In one embodiment, the side floats 120 can be selectively folded in half for storage. In one folding embodiment, the side floats 120 can be folded from four feet in length to two feet in length.
The foldable side extensions 113 define hingedly attached members that are selectively positionable in a deck position in which they are parallel with the deck of the base frame 110, as shown in FIG. 3, and a storage position in which they are perpendicular with the deck of the base frame 110, as shown in FIG. 4. It is contemplated that in one embodiment, a lockable hinge is employed to attach the foldable side extensions 113 such that they can be locked in their respective positions. It is understood that the positioning of the side extensions 113 allows for the size of the base frame's 110 deck to be maximized while still enabling it to be broken down into a more easily portable and storable size.
The aft floor board 114 is selectively attachable to the base frame 110. In the preferred embodiment, the aft floor board 114 is attachable through a conventional lift BiscuitTM tabs. It is appreciated that when in place, the aft floor board 114 extends the deck of the base frame 110, thereby providing additional space on which to move thereon. On the other hand, by removing the aft floor board 114 (while the side floats 120 are in place and the multi-purpose personal watercraft 100 is in user), a user of the multi-purpose personal watercraft 100 can place their feet or body in the water without fully exiting the boat, whether for leisure or for propulsion. Advantageously, allowing the selective removal of the aft floor board 114, adapts the multi-purpose personal watercraft 100 for easing the entry and exit of the multi-purpose personal watercraft 100 for those with disabilities or who otherwise are uncomfortable entering and exiting over the side of the multi-purpose personal watercraft 100.
Provided the aft floor board 114 is in place, a rudder assembly 130 may additionally be attached to the multi-purpose personal watercraft 100 through a conventional clip fastener. In the preferred embodiment, the rudder assembly 130 attaches to the aft ends of both side floats 120. It is appreciated that by attaching the rudder assembly 130 to both side floats 120, it can be more securely held in place and be centered in the rear of the multi-purpose personal watercraft 100. In the preferred embodiment, the rudder assembly employs a pulley system for control, thereby enabling more efficient control thereof.
The aft floor board 114 additionally includes a drive well slot 114′ that is sized to enable the placement and retention of a pedal driven propeller assembly (not shown).
The base frame 110 additionally includes a bow portion 115 that includes a motor well 116 is sized and shaped to receive and hold a conventional trolling motor 140.
The multi-purpose personal watercraft 100 includes an integrated dual steering system 150 that may be used to control steering through an attached rudder assembly 130 and/or an attached trolling motor 140 (collectively, a “steering device”). In the preferred embodiment, the dual steering system 150 includes two discrete handles, each which may be connected to a single navigation and/or propulsion device.
The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
