A utility sled is formed from a lightweight material and includes a handle flexibly attached to the front end thereof. The handle includes a hook that is seated within a small opening of the utility sled when not in use. A pair of retractable wheels is attached to an exterior of each sidewall of the utility sled. The sidewalls are biased outward when no load is present. When loaded, the sidewalls advantageously tend to straighten vertically. The formed bottom of the sled includes a plurality of ribs which both add strength to the sled as well as function as sled runners when the wheels are retracted. The ribs operate to reduce friction between the sled bottom and the underlying surface.

The present invention relates to a traction device using a drone and, more specifically, to a traction device using a drone, the device being capable of towing, along the progressing direction of a drone and by the thrust of the drone, an operator operating a drone and a carrier on which the operator rides. The traction device using a drone, of the present invention, can be applied to a moving means and leisure activities by allowing a user operating a drone to move in a flying direction of the drone, thereby enabling utilization of the drone to increase. In addition, the traction device using a drone of the present invention has an ascending and descending operation unit and a forward and backward operation unit, which are respectively formed as a rotational type, such as that of a knob dial, so as to facilitate maintenance of a constant altitude and a constant speed of the drone.

A boat includes a planing hull, a propeller, a main rudder, and a pair of flanking rudders. The planing hull has port and starboard sides, a transom, a hull bottom, and a centerline running down the middle of the boat, halfway between the port and starboard sides. The propeller is positioned forward of the transom and beneath the hull bottom. The main rudder is positioned aft of the propeller. The main rudder has a rotation axis about which the main rudder rotates. The flanking rudders are positioned forward of the propeller. One of the flanking rudders is positioned on the port side of the centerline, and the other flanking rudder is positioned on the starboard side of the centerline.

A device comprises a spring and a sleeve. The spring is configured to form a closed loop. The spring is moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded. The spring defines a circumference while in the uncoiled configuration. The spring is disposed within the sleeve.

A tent is designed for use in the air, connected at its vertices to trees or the like. The tent is further designed with enough support from an independent support structure to create a shelter there-in while in the air or on the ground. Further, the tent is built atop a floating mat or base. In order to provide enough strength to the base that it can be used to float the entire tent or hold the tent airborne, straps extend from each vertex of the mat through a central portal and connect back to themselves. From these straps, loops are further created to attach the tent, by way of the loops, to trees while the entirety of the mat is buoyant enough to hold the tent and people there-in afloat.

The present invention relates to a submerged-floating type water house. The house comprises: a first lower side part and a second lower side part formed symmetrically with respect to each other; a first upper side part and a second upper side part formed symmetrically and extending from the first lower side part and the second lower side part; and a front part and a rear part formed in front of and in back of the first lower side part and second lower side part and the first upper side part and second upper side part, thereby forming a rhombic-shaped body and floating in water.

A small boat includes an engine, a display that displays a speed setting image of a boat body and an acceleration setting image of the boat body side by side, an operator including a speed setting operator through which an operation of setting a speed set value is received and an acceleration setting operator through which an operation of setting an acceleration set value is received, and an engine controller that controls the engine based on the operations received by the operator.

An aftermarket adaptor apparatus for a float-board is disclosed. My invention permits a user to adapt a conventional buoyant water float-board (typically a stand-up paddleboard, surf board, or other floatable device), to effectively convert it into a foot-propelled exercise board. The adapted float-board allows a user to travel across, over, and through water by the action and means of the user's feet treading and ambulating upon a treadmill integral to said adaptor apparatus (after its attachment onto said float-board). In practice, the treadmill is affixed onto and over the upper surface of the float-board at the time of the adapter being attached. Accordingly, the affixed adaptor upgrades a simple float-board for treadmill propulsion through the water. The adapted float-board permits a user to self-propel over, across, and through a body of water. This is accomplished by (1) the user attaching said adapter securely onto said float-board, (2) the user positioning the adaptor in place by strapping down the adaptor, (3) the user placing the adapted float-board into the water, and then while afloat and getting underway, (4) the user balancing and standing on top of and treading upon the adaptor's integral foot-actuated treadmill which is suspended over the buoyant coupled assembly comprising the original float-board with its attached propulsion adaptor.

A pod system for use with a houseboat assembly is disclosed herein, with the pod system comprising a first pod and a second pod. The first pod and the second pod are configured to be selectively disposed in a pod slot defined by the houseboat assembly. The first pod is generally free of any locomotive capabilities, while the second pod includes a movement element. When the second pod is disposed in the pod slot, the movement element may be actuated from a helm of the houseboat assembly to impart locomotive capabilities to the houseboat assembly. When locomotive capabilities are not desired, the second pod may be replaced by the first pod in the pod slot. Connectors are provided on the houseboat assembly, first pod, and second pod to removably secure the first pod and the second pod in the pod slot as desired.

The invention relates to a propulsion device comprising a platform that is arranged so as to accommodate a passenger and cooperates with a thrust unit comprising a main nozzle, advantageously oriented from the bow to the stern of the device, and two secondary nozzles that are lateral and are positioned essentially at the bow of the propulsion device. The secondary nozzles are mounted so as to be mobile about a transverse axis so as to be moved by actuators controlled by a processing unit that implements a method for controlling the secondary nozzles, thus providing automatic control assistance to the passenger.
