Abstract: In water or on land, an innovative Dual Retractable Handlebar System with adjustable damping, allows the rider of Motorized Surf Boots to transition from a kneeling, to squatting, to standing, or vice versa, in one smooth articulated motion while keeping a continued grip on the handles and throttles. Each handlebar of the pair is firmly connected to each boot (or board) safely behind the rider, with each handlebar extending around the outside of the rider to a comfortable and ergonomic position to grasp with each hand, providing the rider with the ability to impart body English on the left and right sides independently, in order to effectively steer his or her Motorized Surf Boots on water or on land. Additionally, the pair of Handlebars of the present invention can be quickly locked in the retracted (or down) position, or quickly released for deployment in a range of up positions.

Abstract: The invention relates to a water board (2) made of a material that can float on water, having a support area (8), on which a user rests at least partially. To reduce the current forces acting on the user while holding on to and being towed behind a motorized watercraft (24), it is proposed that the water board (2) has, at a front-end area, an attachment segment (22) for the articulation of the water board (2) to the watercraft (24).

Abstract: A hydrofoil craft includes a deck, a hydrofoil disposed below the deck, a thruster that generates a thrust, and a thrust operator. The deck includes a chest placing portion on which a chest of a vessel operator is placed and a lower-limb placing portion that is disposed at a more rearward position than the chest placing portion and on which a lower limb of the vessel operator is placed, and the deck is arranged such that the vessel operator is able to ride on the deck in a prone position. The thrust operator is operated by the vessel operator to adjust the thrust of the thruster.

Abstract: A watercraft has a hull having a bow, a deck disposed on the hull, an engine connected to the hull, a propulsion system operatively connected to the engine, a first bow sponson disposed on a starboard side of the bow, and a second bow sponson disposed on a port side of the bow. A sponson suitable for use on a bow of a watercraft is also disclosed.

Abstract: A watercraft with several stability and handling design improvements. It has an enhanced reactive suspension system positioned in the vessel between a set of separating hull and body components. The watercraft also has improved braking, steering and stabilizing systems designed around multiple pivoting mechanisms on the vessel hull that work individually or in unison to achieve the desired braking or steering effect. The stabilizing system is operated by a computerized, gyroscopic hydraulic control to maintain stability and comfort of ride, minimizing the roll, pitch and yaw commonly experienced in the passenger compartment.

Abstract: Watercraft structure, in particular an aquabike, comprising a first elongated floating body (5) and a second elongated floating body (6) connected to the first floating body and arranged parallel to it spaced at a determined distance. Between two floating bodies (5, 6), furthermore, a seat (16) is provided, which can be associated to a footrest and is connected by a rod (26) to the floating bodies (5, 6), on which one or more users can sit. For increasing the lifting forces pushing against the floating bodies (5, 6), a hydrodynamic lifting transversal element (30) is provided arranged at the barycentre of the watercraft (101). The hydrodynamic lifting transversal element (30) in use has an upper surface (31) that faces the floating bodies (5, 6) and a lower surface (32) opposite to the upper surface (31).

Abstract: A small planing watercraft can have a hull, an engine, and a steering assembly. The steering assembly can be configured to be translatable in the fore and aft direction, as well as pivotable about a generally horizontal axis so as to provide more flexibility in accommodating different. Optionally, a watercraft can include moveable members on a bottom surface of the hull so as to change a turning characteristic of the watercraft.

Abstract: A small boat has left and right sponsons extending in a longitudinal direction and respectively attached to left and right side walls forming a boat body. The sponsons are provided with an attachment section contacting a left side wall, a gliding section extending substantially horizontally from a lower edge of the attachment section, an inclined section connecting to a side edge of the gliding section, an upper edge of the attachment section, and projecting sections extending from an upper edge to a lower edge of the inclined section. Water flowing along the inclined section is guided by the projection sections and removed or separated from the inclined section. Accordingly, a small boat that turns through a small arc turning locus is provided, e.g., a small boat that is capable of relatively tight turning.

Abstract: Tunable sponsons for personal watercraft and personal watercraft having the tunable sponsons. The present invention provides personal watercraft having sponsons with an adjustable height relative to the water surface and the hull. One adjustable sponson has a horizontally, outwardly extending portion from the personal watercraft hull followed by a downwardly extending portion including a fin for penetrating below the water surface. The effective height of the sponson outwardly extending portion above the water can be reduced or lowered by adding a thickness of slab of material along the length under the sponson outwardly extending portion. One tunable sponson includes apertures mounted along the sponson underside for securing additional material. The effective height of the sponson horizontally extending portion above the water can be increased by removing a removable sponson extension previously secured to the sponson.

Abstract: A stabilizing fin assembly for use with a watercraft includes a mounting structure, a stabilizing fin structure, and a releasable securement structure. The mounting structure is fixedly attached to a side portion of a hull of a watercraft. The stabilizing fin structure is removably mounted to the mounting structure. When the mounting structure is fixedly attached to the hull, the stabilizing fin structure is disposed externally of the hull and adjacent the side portion of the hull in an operative position wherein at least a portion of the stabilizing fin structure extends into a body of water while the watercraft is in a normal operative position. The releasable securement structure is disposed in a releasably secured position on the hull. The stabilizing fin structure facilitates removal and replacement of the stabilizing fin structure without requiring access to the interior of the watercraft.

Abstract: An adjustable sponson for a personal watercraft allows the vertical position and the angular orientation of the sponson to be adjusted to suit the particular size and riding style of each rider. Each adjustable sponson includes a sponson body. At least one locking mechanism releasably attaches the sponson body to the hull side. A guide mechanism allows the sponson body to move vertically relative to an outer chine of the watercraft hull when the locking mechanism is loose. The guide mechanism also permits the ends of the sponson body to move independent of each other so that the angular orientation of the sponson body relative to the chine can be altered. When locked, the locking mechanism prevents movement of the sponson body over the hull side surface.

Abstract: A hull-less personal water craft is provided which reduces air, water, noise, and wake pollution over personal water craft presently on the market. The craft includes a strut assembly having forward and rearward ends, with an operator platform attached at the rearward end, and having at least one hydrofoil positioned below the operator platform. A propulsion system is provided, as is a control column which provides the operator interface when the craft operator is kneeling, standing or sitting on the operator platform. The hydrofoil provides substantially all of the lift for the craft when in operation, and the elimination of a hull greatly reduces the power requirements and wake generated by the craft in operation.
