An adaptable landing gear assembly for small watercraft such as kayaks and canoes is described supporting transport of such watercraft from a point on land to a body of water. The assembly includes a cross member to secure the assembly to the watercraft, a pair of positioning brackets, and a pair of wheeled leg assemblies that can rotate between a vertical position to transport watercraft on land and a horizontal position to enable unfettered use of watercraft while floating on water. A position holding pin engages with retaining slots in said position brackets to enable fixed positions of the wheeled leg assemblies with respect to the cross member. A convenient release lever enables operator to release the position holding pin and rotate leg assembly from a first position to a second position.

A hard shell boat cover is disclosed herein. The hard shell boat cover includes a plurality of boat cover sections, the plurality of boat cover sections configured to interlock with one another so as to form the hard shell boat cover, and one or more of the plurality of boat cover sections configured to engage with a top peripheral edge of a boat; and at least one securement element attached to one of the plurality of boat cover sections, the securement element configured to be coupled to a securement strap for securing the hard shell boat cover to the top peripheral edge of the boat.

A mobile extraction assembly includes a sled with a tow line secured to a front end of the sled. The mobile extraction assembly also includes a cart including a frame, a winch, and a pulley. The frame defines a track for receiving and supporting the sled. The winch is mounted to the frame underneath the track. The pulley is vertically disposed in line with or above the track, where the tow line is secured to the winch and routed around the pulley between the winch and the sled. This allows retraction of the tow line by the winch to draw the sled to the cart and onto the track of the cart in a direction towards the pulley.

There is disclosed herein systems and apparatuses for use with personal watercraft having a top side, a bottom side, a long axis, fore and aft sections and at least one passenger opening defined in the top side between the fore and aft sections, the systems and apparatuses including at least two legs each having a first end and second end, and each attachable at its first end to the watercraft and each having disposed at its second end a wheel; an inflatable bladder attachable to the watercraft; a compressor in fluid communication with the bladder; and a control unit for activating the compressor to inflate the bladder from a stowed configuration to a deployed configuration.

A novel trailer securing and releasing mechanism for a boat is disclosed to facilitate the process when unloading and releasing a boat into the water as well as loading the boat back on the trailer via securing the boat's eye bolt, or ring. The invention device encompasses a spring- or hydraulically-activated mechanism normally attached to the trailer tongue. The boat loading mechanism operates by movement of a horizontal rod being forced in the direction toward the trailer resulting from contact by the boat ring. This contact and movement of the rod forward results in positioning the boat ring within an open claw-like device and, simultaneously, causes the open claw to slam shut wherein each claw arm lies with the boat ring and thereby affixing the boat to the trailer. As the rod arm is moved back within its housing by the forward motion of the boat the energy of said movement is captured and retained, either by a compression of a spring or of a fluid (gas or liquid) within a hydraulic mechanism. Subsequent disengagement of the boat ring from the claw-like device on the boat trailer results from release of the stored energy within the compressed spring (or fluid) to reverse the direction of movement of the horizontal rod that will result in the simultaneous opening of the claw mechanism and pushing of the rod head against the boat ring to release the boat from the trailer.

The present invention discloses a wheel structure and a kayak using the same, relating to the field of ships. The wheel structure mainly comprises wheel bodies, a shaft and a support rod, wherein the connecting piece is arranged at one end of the support rod opposite to the wheel body, a bidirectional ratchet wheel mechanism is arranged between the shaft and the support rod, the bidirectional ratchet wheel mechanism can selectively control the shaft through adjustment, to make same rotate only in one direction, and then achieve the purpose of controlling the rotation direction of the wheels; the wheel structure is mounted on the kayak, when being loaded, the kayak is effortlessly pushed under the action of wheels, and the rotation direction of the wheels is limited by the bidirectional ratchet mechanism so that the wheels can only roll towards the vehicle, therefore, the pushing person does not need to powerfully offset the retreating force of the wheels, that is, it is easier and effortless to push the kayak to be loaded.
