20130340661 | SAIL PADDLE FOR STAND UP PADDLE BOARDS - A paddle for stand-up paddle boards includes a paddle blade at a lower end of the paddle shaft and a sail assembly slidingly stowed within the shaft, with the sail deployed by sliding the sail assembly distally out of the shaft upper end. The sail assembly may include a sail and support frame. A method and system for transporting a user across water or other surfaces has a board for the user to stand upon and a paddle with sail slidingly deployed from inside a paddle shaft via an opening in the upper end. To propel via paddling, the user leaves the sail stowed within the shaft. The propel via wind, the user deploys the sail out of the shaft, places the blade onto the board upper surface, and angles the paddle and sail to catch the wind and propel the user across the water. | 12-26-2013 |
20150033997 | Multipurpose Stabilized Water Board for Recreational Use - This invention provides for a new design of recreational water boards that are significantly more stable than traditional boards in the class of standup paddle boards, windsurfing boards, and surf boards. Higher stability is achieved by shifting the primary buoyancy of the board to the “rail hulls” located on each side of the board deck creating a tunnel-hull effect. This provides a unique ability to make the board more stable for the average or beginner rider. This new design is intended to be a multipurpose platform allowing the rider to use as a standup paddle board, windsurf board, and surf board. In addition because the design is very stable it can be configured with a removable seat to allow the rider to paddle while seated. The increased stability provided by the tunnel hull effect also eliminates the need for a fixed rudder or fin to generate directional stability. | 02-05-2015 |

20100162933 | Twin Sailing Board - The present invention relates to a twin sailing board characterized in including a pair of surfboards ( | 07-01-2010 |
20110023762 | Structure for Sport Board - An improved structure for a sport board comprises: a first layer, which is a low density foam layer and has a first surface and a second surface; a second layer, which is a hardened layer, a first surface of the second layer being joined the second surface of the first layer; a third layer, which is a low density foam layer, a first surface of the third layer being joined a second surface of the second layer; and a cover layer, which is a waterproof layer, a first surface of the cover layer being completely joined the first surface of the first layer and a second surface of the third layer. | 02-03-2011 |
20110197798 | SAILBOARD STEP DESIGN WITH LESS VENTILATION AND INCREASED SPEED - A step shape in a planing hull for water craft and more particularly for sailboards, surfboard or PWC for increasing the lift in front of the step and decreasing it in back at high planing speed, which has dynamic lift directly behind the step when the hull is traveling at a transition speed between displacement mode and planing mode, but at high planing speed it does not have lift directly behind the step. The hull has increased speed because the lift behind the step at transition speed allows the position of the step to be moved forward and in one embodiment has cambered surface ( | 08-18-2011 |
20130206047 | SYMMETRICAL WINDSURFING BOARD - A windsurfing board may include an elongated hull having an upper deck side, a bottom side, a geometrical midpoint on the bottom side, a geometrical axis x extending through the midpoint and along the length of the elongated hull, a geometrical transverse axis y extending through the midpoint and in a direction that is perpendicular to the axis x, and a geometrical vertical axis z extending through the midpoint and in a direction that is perpendicular to both the axis x and the axis y. The hull may include one single hull body. The windsurfing board may also include a universal joint and at least one lateral resistance inducing projection projecting from the bottom. The bottom side of the windsurfing board may be symmetrical around the axis y, so that the parts of the bottom side that are divided by the axis y are mirror images of each other. | 08-15-2013 |

20100050916 | Wind-Powered Personal Hydrofoil Watercraft - A personal wind-powered hydrofoil watercraft having a sail supported by a mast coupled to a buoyant body, where the mast is tiltable forward and backward but not side to side, in order to prevent excessive rolling of the buoyant body when it is lifted clear of the water on the hydrofoils. Additionally, the buoyant body may be in the shape of a pontoon, the watercraft may be steerable by a steering mechanism actuated by a human operator's foot or feet, and the front hydrofoil may be associated with a surface tracking means in order to stabilize the altitude of the watercraft. | 03-04-2010 |
20110030600 | SAILBOARD WITH SLOTTED WINGLETS - A winglet in a planing hull for sailboards with longitudinal length at least three times its transverse width, or a top slot that covers at least half the winglet area, and a forward slot and or a top slot, which allows dynamic lift from both the top and bottom surface of the winglet when the board is traveling at a transition speed between displacement mode and planing mode, but at high planing speed it does not normally have lift from the top surface of the winglet. This winglet may have a camber/slope step on the planing surface. In addition the transverse section of the nose of the hull can have the shape of an upside down wing. | 02-10-2011 |
20110155033 | Improved Ventilated Hydrofoils for Watercraft - A hydrofoil section comprises first and second faces that create, in operation at speeds above a ventilation speed, a ventilated cavity defined by a first cavity face which departs from the first hydrofoil face and a second cavity face which departs from the second hydrofoil face. Each cavity face represents a free surface and each face separating from the said free surface at a discontinuity on that surface, the separated faces forming a continuation of the faces of arbitrary shape and enclosed by the free surfaces without contacting the said free surfaces. Below the speed at which full ventilation occurs the arbitrarily shaped portion of each face is configured to provide a modified flow configuration resulting in changed lift and or drag and or pitching moment under partial, or unventilated operation. | 06-30-2011 |
20130298813 | SAILBOARD WITH SLOTTED WINGLETS - A sailboard hull has at least one pair of winglets or foils beneath the top of the board. Each winglet or foil has above it a slot and allows dynamic lift from both the top and bottom surface of the winglet and reduction of drag when the board is traveling at a transition speed between displacement mode and planing mode. At high planing speed it does not normally have lift from the top surface of the winglet. There may be multiple pairs of winglets or foils. Back slots may be provided at the rear of the sailboard hull providing a higher ratio of winglet width to maximum hull width. A top slot may cover at least half the winglet area, and a winglet may have a camber/slope step on the planing surface. | 11-14-2013 |
20150298776 | Leash Retaining Fin - A fin shaped and sized to connect to a leash so that the leash is securely stored during transport or storage.
