An apparatus for mounting a pedal propulsion system to a watercraft, having a mount portion configured to be attached to the watercraft, a link support, and upper and lower links pivotally connected to the link support and to the mount portion. The link support and upper and lower links are configured to form part of a four-bar linkage arrangement and to simultaneously move together between an extended, operable position for operating the propulsion system, and a retracted, stowed position elevated above the extended position, for loading, transporting, unloading and/or launching the watercraft in the water. A column clamp is configured for selectively fixing a drive column of the pedal propulsion system to the link support, wherein the drive column, the link support and the upper and lower links are configured to simultaneously move together between the extended and retracted positions.

A modular hybrid propulsion unit is disclosed that is mountable to a watercraft. According to an example, the modular hybrid propulsion unit includes a housing configured to fit within a complementary housing receiver on a topside of the watercraft, and a rotational output coupling configured to rotationally engage with a rotational input coupling for a propeller of the watercraft. The propulsion unit further includes an electric motor within the housing, the electric motor having a motor shaft connected to the rotational output coupling for providing an electrically powered rotational input to the rotational output coupling. The propulsion unit further includes a crank having one or more crank arms. The crank is connected to the rotational output coupling for providing a human powered rotational input to the rotational output coupling independent of the electrically powered rotational input by the electric motor.

The present invention relates to a cooler floatation device comprised of a generally rectangular body comprised of a plurality of elbows and sidewalls. Each elbow and sidewall may further be comprised of a mounting eyelet that allows for a plurality of attachments to be attached to the device. In addition, the eyelets further receive securing straps, wherein the straps can be placed over the top/bottom surface of the cooler, to secure the cooler inside the device and prevent the cooler lid from opening. The interior side surfaces of the sidewalls/elbows may also be comprised of a rubber liner that protects and insulates the side surfaces of the cooler from being scratched by the sidewalls/elbows. The plurality of attachments of the device may include a handle, an anchor, a tow strap, a waterproof storage box and a foldable tray table.

A unique watercraft that includes a plurality of flotation elements which are aligned longitudinally and fit together end to end, comprising the watercraft hull. Unlike other watercraft, it does not rely upon a low center of gravity for stability. A front flotation element pivots about an axis and this pivotal motion is used for both steering and for maintaining balance. The effective profile of the hull changes dynamically as the front flotation element is turned. These hull changes allow the operator to balance and make agile maneuvers. Equilibrium can be easily maintained in this manner when the watercraft is moving forward and when it is otherwise stationary in water. In a preferred embodiment, the watercraft is ridden like a bicycle. Balance is actively maintained by a rider who steers right and left to adjust transverse weight distribution. The riding experience feels similar to operating a conventional bicycle on land.

An inflatable ride-on water toy comprising a stylized body that is connected to a separately inflated safety ring using a variety of configurations.

An underwater propulsive device of a watercraft including a flotation unit on which a user rides. The propulsion device includes: a hollow body coupled to the flotation unit through a strut and extending in a propulsive direction of the watercraft, the inside of the hollow body being divided into a first compartment and a second compartment; a motor in the first compartment; a propeller in the second compartment; and a power transfer shaft extending in the propulsive direction and connecting the motor and the propeller to each other. The first compartment has a waterproof structure. The second compartment has a water inlet disposed closer to the bow than the propeller is and extending along a circumference of the power transfer shaft and a water jet outlet disposed at a stern-side end of the second compartment. The propeller is smaller than the first compartment in diameter.

A therapeutic flotation device and a therapeutic method of use thereof is disclosed. The device includes a plurality of buoyant float elements and a member (an elongated web strap) that couples each of the buoyant float elements such that the buoyant float elements are serially aligned along the member. A first end of the member is secured to a second end of the member. A mating mechanism, such as a buckle, secures the first end of the member to the second end of the member, or the two ends of the member may be permanently secured to each other using an adhesive or by being sewn together. Each of the buoyant float elements has a center aperture aligned along the center of a cross-section thereof. The member is preferably coupled to each of the buoyant float elements by being sequentially passed through the center apertures of each buoyant float element.
