| 35 | Paddleboard and process | US13410304 | 2012-03-02 | US08808047B2 | 2014-08-19 | Eric Knutson |
| A paddleboard (10) comprising a right board (12) slidingly connected to a left board (14). At least one interlocking sliding element is connected to the right board 12, and at least one interlocking sliding element is connected to the left board 14. Right board (12) and left board (14) are slidable longitudinally with respect to one another only within the plane of paddleboard (10), and parallel to the long axis of paddleboard (10). Utilizing a user's legs and feet to slide right board (12) and left board (14) longitudinally causes a propulsion system to propel paddleboard (10) over the water. A suitable propulsion system comprises pivoting paddles (16) or flaps (40) mounted under right board (12) and under left board (14). | ||||||
| 36 | Internally mounted watercraft rowing fin system | US12856309 | 2010-08-13 | US08419487B2 | 2013-04-16 | Jack Parker |
| An internally mounted rowboat rowing fin system that includes two rotating fin assemblies mounted on the inside surface of the watercraft's opposite sidewalls. Each fin assembly includes a rotating vertical post held on the inside surface of the sidewall by a mounting tube selectively mounted or integrally formed on the sidewall. Longitudinally aligned and disposed inside each mounting tube is a hollow, elongated sleeve. Disposed inside each elongated sleeve is a rotating post that extends upward above the gunwale and into the water below the elongated sleeve. A pivoting fin arm with a flexible fin attached thereto is pivotally attached to the lower end of each rotating post. Attached to the upper end of each rotating post is a perpendicularly aligned handle bracket. A rowing handle is pivotally attached at one end to the handle hinge. During use, the two handles extend inward from the sidewall and are grasped by the rower. Both handles are able to swing in a vertical 180 arc over their respective handle hinges thereby allowing the fins to rotate 180 and sweep in opposite directions. | ||||||

| Provided is a paddle retaining device which may be easily mounted to a stand-up paddle board, wherein the paddle retaining device is specifically configured and adapted to allow a user to quickly and easily securing the paddle to the board. The paddle retaining device may be attached to the board without significantly interfering with the structure and integrity of the paddle surfboard. Along these lines, the paddle retaining device may be secured to the board without drilling holes or making other material modifications to the structure of the paddle surfboard. | ||||||
| 38 | Push pole for a boat | US12005886 | 2007-12-28 | US07942106B2 | 2011-05-17 | Brad Cromartie |
| A push pole for manually propelling boats, including a shaft and a foot. In a preferred embodiment, the foot is flared at the bottom end in an inverted V-shape, and a pivoting pin is located along one side of the foot, and pivots outwardly from the foot so that it may be used to retrieve lures or as a docking hook. When the pin is not in use, it may pivot back into a receiving cavity within the side of the foot, forming a streamlined edge thereof. In one embodiment, the pivoting mechanism of the pin may include a spring to bias the pin in an outward direction, as well as means for locking the pin into the inward streamlined position when not in use. The pivoting pin may be locked into either the extended or retracted position. Further, the foot may be detachable from the shaft in any desired manner, and replaced by a net, paddle, gig, scrub brush, gaff, docking hook or spike that attaches in the same manner as the foot. Additionally, in a preferred embodiment, the push pole is buoyant in water, and includes a telescoping shaft that may be extended or retracted. A detachable hook is also disclosed. | ||||||
| 39 | Self-propelled hydrofoil device with flexible steering assembly | US12313541 | 2008-11-20 | US07819074B2 | 2010-10-26 | Shane Chen |
| A self-propelled hydrofoil device that includes a front foil, a rear foil, a user platform, a steering shaft and a frame that couples these components. The steering shaft preferably has a top section and a lower section, the top section being substantially rigid and the lower section being flexible relative to the top section. The top and lower sections may be formed of different materials or may be formed of the same material, integrally or non-integrally. The top and lower sections are preferably offset by an angle, α, to achieve more ready bending of the lower section. | ||||||
| 40 | Self propelled hydrofoil device with leverage-based control of drive foil | US11593141 | 2006-11-03 | US07802534B2 | 2010-09-28 | Shane Chen |
| A self-propelled hydrofoil device having front and rear foils, a support structure and a steering mechanism. The hydrofoil device is preferably configured such that a user can change the angle of attack of the drive foil and/or the height of the hydrofoil device in the water by placing the handle bar to a corresponding position. The steering mechanism is movably coupled to the user platform in a manner that provides a user with sufficient leverage to move the handle bar. A flexible steering-shaft joining member and dihedral foil configurations, among other features, are disclosed. | ||||||
