A watercraft having a body with an opening for a user, a seat, at least one drive mechanism placed at least partially within the opening; an intake configured to allow a flow of water from a body of water surrounding the watercraft; a pump configured receive the flow of water and accelerate the flow of water, and a user controlled discharge configured to receive the flow of accelerated water from the pump and discharge the accelerated water to the water surrounding the watercraft such that the watercraft moves in a direction chosen by the user.

A watercraft and associated pedal drive system are provided. Method of operating the pedal drive are also provided. The pedal drive system allows for unassisted manual pedaling to provide thrust to the watercraft. The pedal drive system also provides on demand pedal assistance of varying levels via an assist drive train having an electric motor to supplement the manual pedal force input provided by a user at the pedals of pedal drive system.

The invention comprises a paddle board apparatus and method of use thereof, comprising: a manual crank connected to a drive shaft, a rotatable housing, and a set of paddle wheels connected to an outer surface of the rotatable housing, where a child manually turning the crank simultaneously propels the paddle board forward in water through use of the paddle wheels and drives an air pump in the rotatable housing to blow bubbles about the paddle board for enjoyment of the child riding the paddle board.

The human powered hydrofoil bicycle includes multiple subsystems integrated together including a structural frame subsystem with associated steering and tiller module, a hydrofoil subsystem to provide vehicle lift, and a powertrain subsystem. The structural frame subsystem may be fitted with buoyancy modules to provide the overall vehicle with a near neutrally buoyant character. The structural frame subsystem also supports a seat for an operator and provides structural support for the steering and tiller module for the hydrofoil subsystem and the drivetrain subsystem. The hydrofoil subsystem includes multiple hydrofoil elements at lowermost portions of the vehicle. These hydrofoil elements generally include in a preferred embodiment a larger rear foil and a smaller front foil. The powertrain subsystem generally includes pedals rotatably supported on the vehicle at a convenient location for engagement and driving by feet of an operator. Power transmission elements extend from the pedals down to a prime mover such as a propeller.

A propulsion apparatus adapted to be installed in a watercraft may include a propeller extending below the water surface adapted to provide three hundred sixty degrees (360) of directed vector thrust. The propulsion apparatus may include foot pedals operable by an operator in a cycling motion operatively connected to the propeller by a drive shaft interconnecting a crank gear assembly to a propeller gear assembly. The drive shaft may extend through vertically aligned concentric upper and lower conduits. The upper conduit may be fixedly secured to the watercraft and the lower conduit rotatably connected to a lower distal end of the upper conduit. The lower conduit may be rotated to direct propeller thrust to a desired direction.

A watercraft and associated pedal drive system are provided. The pedal drive system allows for unassisted manual pedaling to provide thrust to the watercraft. The pedal drive system also provides on demand pedal assistance of varying levels via an assist drive train having an electric motor to supplement the manual pedal force input provided by a user at the pedals of pedal drive system.

An apparatus and methods according to the present invention provides a human powered catamaran-styled watercraft and methods of configuring and operating the watercraft. The watercraft generally comprises at least one hull in communication with a folding collapsible frame, wherein in the frame comprises a center rack pivotally joining hulls of hull sets to provide for common pivoting of the hulls during articulation of the watercraft, thereby the hulls and frame are in further communication through a at least one pivot pad which provides for slidable pivoting of the hulls during articulation of the watercraft. A method of folding and reversibly extending the watercraft to provide for optimized storage is provided. A method of operation of the watercraft to provide for articulation of the watercraft is provided.

A watercraft suitable for fishing has a rotomolded deck and hull. The deck includes a cockpit with substantially vertical sidewalls, a rear wall, a pedaling installation, and a flat floor between the sidewalls extending from the rear wall to the pedaling installation in the cockpit. The hull includes a depression between lateral protrusions amidships and a stern with a rounded cross section so that the combination of the lateral protrusions and rounded stern cross section allow the watercraft to track straight on water and for the stern to move laterally when the watercraft is turned on a body of water. The watercraft may also include a seat movably mounted onto spaced apart grooves installed on the flat floor of the cockpit that extend from a rear position near the rear wall to a forward position near the pedaling installation.

The drive module buoyancy body is either made as a solid material, inflatable or as a hollow body with inflatable air chambers inside, which includes a seat and a shaft mounted in a front portion and extending in a direction transverse to the longitudinal direction of the buoyancy body. Paddle wheels are mounted at the ends of the shaft. A profile is articulated to the shaft in its center so as to be able to pivot about its lower end region, which profile extends upwards from the shaft and in which a crankshaft with a drive wheel is mounted at the upper end region of the profile. The cranks of the crankshaft can be optionally equipped with pedals for a foot drive or crank handles for a hand drive. By driving the cranks, the paddle wheels are driven by a roller chain or a toothed belt, the profile (7) being able to be engaged in a pivoted position for foot drive and being able to be engaged in a position different therefrom for manual drive.
