Description

FIELD

The disclosure relates to watercraft rowed by a person in the standing position while facing the direction of travel.

BACKGROUND

Standup paddle boarding is a popular recreational sport involving a rider standing atop a floating craft and using an unmounted oar to paddle the craft. Traditional paddle boarding utilizes one oar, which is not affixed to the craft, and the rider's body, as the sole source of propulsion. Propulsion is provided by replicating a paddling stroke similar to that of a canoer. Generating propulsion with a paddle when the paddle is not mounted to the craft is inefficient as no mechanical leverage is utilized. Additionally, propulsion provided by a single paddle requires a rider to alternate strokes on either side of the craft to maintain a straight course. Traditional sculling boats utilize a fixed fulcrum and sliding seat to provide more efficient propulsion. In traditional sculling, however, one must face rearwards and utilize a sliding seat mechanism. The sliding seat mechanism of a sculling or rowing boat provides mechanical leverage, but is not practical for use in a standing position. Accordingly, there has been a long-felt need for improved efficiency and performance of watercraft, and in particular for a craft powered by forward-facing rowing in a standing position and including a fixed fulcrum and slide to provide mechanical leverage.

SUMMARY

One aspect of the disclosed watercraft features a hull having first and second opposed ends; a deck affixed to the hull, the deck including a surface for supporting a rider; and an outrigger attached to the deck, the outrigger including a pivot point that extends outwardly from the deck, the pivot point being capable of accepting an oar. In one such embodiment, the oar is capable of rotating in the pivot point so as to allow a rider to employ a “j-stroke” to provide forward course correction when powering the watercraft with one oar. As will be evident to one of ordinary skill in the art having the benefit of this summary, the outrigger can be adapted to include a second pivot point extending outwardly from the deck, the second pivot point being capable of accepting a second oar.

In one embodiment, the watercraft includes a footboard attached to the deck for receiving the foot of a rider. The footboard may be any surface that allows a rider to apply force thereto with the rider's foot. In some embodiments, the footboard may also include a foot strap to restrain a rider's foot to the footboard.

In another embodiment, the outrigger, including pivot points, is adapted to be removable from the deck of the watercraft. In such an embodiment, the outrigger is removably attached to the deck of the watercraft by any suitable means, including screws, clips, or a recess formed in the deck of the watercraft.

In various embodiments, the watercraft includes a slide assembly affixed to the deck of the watercraft. The slide assembly includes a first rail and a second rail mounted longitudinally to the deck of the watercraft and configured to allow longitudinal movement between the first rail and second rail. In such embodiments, the outrigger with pivot point, and footboard are attached to the second rail of the slide assembly. It will be evident to one of ordinary skill in the art having the benefit of this summary that the outrigger may include a second pivot point capable of accepting an oar. In one preferred embodiment, the slide assembly includes a set of first rails and a set of second rails.

In one embodiment, the watercraft includes a brake mechanism attached to the second rail of the slide assembly that interacts with the first rail of the slide assembly to prevent movement as between the first rail and the second rail. In some embodiments, the brake mechanism includes a contact surface connected to a boss, which may include a post or other support structure, which is inserted in a recess formed in the second rail of the slide assembly. In such an embodiment, a spring, which may surround the post, may interact with the post and the second rail to urge the brake mechanism in a disengaged position relative to the first rail. In another embodiment that also includes a spring, the spring interacts with the second rail and the contact surface to urge the brake mechanism in a disengaged position relative to the first rail. Upon application of pressure to the contact surface, the spring is compressed, and the post engages a brake receiving recess formed in the first rail of the slide assembly. The engagement of the post in the recess prevents relative movement between the first rail and the second rail of the slide assembly.

In alternative embodiments, the brake mechanism is capable of maintaining an engaged position relative to the brake receiving recess.

In other embodiments, the brake mechanism includes a contact surface, and may include a friction surface connected to the contact surface. That connection may include a boss inserted into a recess formed in the second rail. A spring attached to the friction surface urges the brake mechanism in a disengaged position relative to the first rail. Upon application of pressure to the contact surface, the spring is compressed, and the friction surface contacts the first rail of the slide assembly. The contact of the friction surface with the first rail of the slide assembly restricts movement between the first and second rails.

In another embodiment, the brake mechanism further includes a caliper retaining friction surfaces connected to the contact surface. Upon application of pressure to the contact surface, a caliper urges a friction surface into contact with the first rail.

In another embodiment, the invention includes a paddle board configured for a standing rower that includes a surface for supporting the rower, a slide assembly with a first rail and a second rail configured for longitudinal movement as between each other, an outrigger with at least one pivot point and a footboard with a restraining strap both attached to the second rail of the slide assembly. The first rail and second rail are configured to allow longitudinal movements as between the first rail and second rail. In a preferred embodiment, the slide assembly includes a set of first rails and a set of second rails.

In some embodiments, a first rail of the slide assembly includes a plurality of bearings retained in the first rail, and a second rail adapted to receive the first rail so as to allow longitudinal movement as between the first rail and the second rail. In still other embodiments, the bearings are retained in carriages attached to a second rail, and the carriages are adapted to receive a first rail of the slide assembly.

In yet another embodiment, the slide assembly, including the outrigger, pivot points, and footboard, are adapted to be removable from the deck and hull. In such an embodiment, the slide assembly, including the outrigger, pivot points, and footboard, are removably attached to the deck of the watercraft by any suitable means, including screws, clips, or a recess formed in the deck of the watercraft.

In some embodiments, the hull and deck may comprise a unitary assembly. Such unitary assemblies may include surfboards, sculling boats, paddleboards, skiffs, dories, and other composite watercraft.

The following detailed description of exemplary embodiments of the novel watercraft is for purposes of illustration and enablement only, but is not intended to limit the scope of the appended claims. Various changes may be made in the function and arrangement of the elements described in these embodiments without departing from the scope of the appended claims. The description herein may be adapted and employed with alternatively configured devices having different shapes, components, mechanisms, structures, materials and the like

FIG. 1 depicts a top view of one embodiment of watercraft 100 including hull 102 and deck 104 affixed to hull 102. Hull 102 and deck 104 each have bow 106 and stern 108 ends. The embodiment depicted in FIG. 1 includes slide assembly 110 affixed to deck 104. Slide assembly 110 includes a set of first rails 112 affixed to hull 102 and configured to receive a set of second rails 114. First rail 112 and second rail 114 are joined so as to allow lateral movement as between first rail 112 and second rail 114. Restraining strap 119 is attached to footboard 118 to restrain a rider's foot. Outrigger 116 is attached to the bow-end of slide assembly 110 and footboard 118 is attached to the stern-end of slide assembly 110. Outrigger 116 includes two pivot points 120 that are adapted to accept one oar 122 each. In some embodiments, outrigger 116 includes only one pivot point 120 and oar 122. Pivot points 120 may be open or closed oarlocks, or another structure sufficient to support oars 122 when in use.

FIG. 2 shows an isometric view of FIG. 1.

In an alternate embodiment of watercraft 100, outrigger 116 is attached directly to deck 104 with or without need for slide assembly 110. Without the slide assembly, outrigger 116 does not move relative to deck 104. Outrigger 116 may be attached to deck 104 with conventional fastening systems including, but not limited to, threaded and non-threaded fasteners, or adhesives. It is further contemplated that outrigger 116 may be attached to deck 104 with attachable or integral clips, or recess formed in deck 104 of watercraft 100.

In one embodiment, slide assembly 110 is substantially permanently attached to deck 104. Slide assembly 110 may be attached to deck 104 with conventional fastening systems including, but not limited to, threaded or non-threaded fasteners, or adhesives. In alternative embodiments, slide assembly 110 is removably attached to deck 104 to allow watercraft 100 to be used as a traditional paddle board. In such an embodiment, outrigger 116 is removably attached to deck 104 of watercraft 100 by, for example, screws, clips, a recess formed in deck 104 of watercraft 100, or by other suitable means.

With reference to FIG. 3a, a rider using watercraft 100 places a foot on footboard 118. With one foot secured to footboard 118 by restraining strap 119, and the other foot on deck 104, a rider uses a foot to move footboard 118 forward, which moves set of second rails 114, outrigger 116, and pivot points 120 to a forward position. Simultaneous with the application of forward force to footboard 118, the rider applies rearward force to handles 123 of oars 122 causing the blade end 125 of oars 122 to move to a forward position. From the forward position depicted in FIG. 3a, a rider simultaneously moves handles 123 of oars 122 forward while moving footboard 118 rearward. The rider's rearward force on footboard 118 causes set of second rails 114, outrigger 116, and pivot points 120 to move towards stern 108 of watercraft. Rearward movement of outrigger 116 and pivot points 120, combined with forward movement of handles 123 of oars 122, result in blade ends 125 of oars 122 moving rearward. FIG. 3b depicts the watercraft during the middle of a rider's stroke. With continued application of rearward force to footboard 118, and application of forward force to handles 123 of oars 122, footboard 118, set of second rails 114, outrigger 116, and pivot points 120 travel to a rearward position, as depicted in FIG. 3c. This represents the end of the rider's stroke and the sequence begins again by application of forward force to footboard 118 and moving footboard 118, set of second rails 114, outrigger 116, and pivot points 120 to a forward position, as depicted in FIG. 3a.
