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 tracked, amphibious vehicle, comprising at least two, spaced, elongated pontoons disposed generally parallel to one another. A platform structure can be supported by and structurally connects the pontoons, the platform structure including a transom, a lowermost generally horizontally extending panel above a free clearance area under a bottom panel and between the pontoons through which terrain and debris can pass. A hydraulic drive system can propel the vehicle, said drive system including left and right hydraulic motors mounted on the pontoons. At least one series of longitudinally spaced bogie wheels for supporting said vehicle can be mounted along the bottom of the pontoons. A continuous, endless belt can encircle each pontoon and engages the bogie wheels. Ground-engaging cleats assembled on the outer surface of each belt and covering the pontoon bottom provide traction to the vehicle. Gearing interfaces the motor with the endless belts. A supplemental, marine drive assembly includes: a hydraulic motor having a rotary device, shaft, with an axis, a propeller shaft having an axis wherein the motor axis and propeller axis are aligned, a universal joint connecting the hydraulic motor to the transom, and a housing including a sleeve that contains the propeller shaft, a first vertical plate connected to the sleeve and a second vertical plate connected to the sleeve below the first plate.

A motorized kayak cart is provided. The cart has a frame for supporting the hull of a kayak, a motor that drives two opposing wheels mounted on the frame, and stabilizing bars that contact a ground surface on which the cart rests and slides along the ground surface in order to maintain the cart in an upright position when the cart is in motion so that the cart does not tip over when in use.

A watertight foldable system comprises a watertight panel in which folds have been made such that the panel may be folded from a flat state into an open-top watercraft such as for example a canoe. The panel comprises a set of folds such that the watercraft, after it has been folded into watercraft, has a bottom having a flat profile in longitudinal direction or having a convex profile relative to the watercraft.

A system is provided that includes a boat; a pair of wheels; for each wheel, an arm to which said each wheel is rotatably mounted, the arm being movable between towing and water configurations. In the towing configuration, the boat is supported for rolling movement on the wheels when dragged from the bow of the boat. In the water configuration the wheels are alongside the boat; and means for coupling the boat to a vehicle, such as a hitch are provided.

Chemical compounds and the therapeutic use thereof, in particular for improving muscular quality in mammals. More particularly, a method of improving muscular quality in sarcopenic mammals and treating and/or preventing sarcopenia using the chemical compounds and, in particular, sarcopenic obesity and the associated complications and/or pathologies thereof, such as loss of strength, muscle mass, performance and of physical and movement capacity. Also, a method of improving muscle quality in obese mammals and treating and/or preventing of obesity and associated complications and/or pathologies, advantageously type 2 diabetes and metabolic syndrome, using the chemical compounds.

A method includes: loading a vehicle onto a connector boat; loading the loaded connector boat onto the semi-submersible ship; transporting the semi-submersible ship having the loaded connector boat stored thereon to a location; taking water ballast onto the semi-submersible ship at the location; floating the loaded connector boat off of the semi-submersible ship; transporting the loaded connector boat to a second location; unloading the vehicle into water; and transporting the vehicle to a third location.

Various examples of transferring a watercraft between land and water are disclosed. When a vehicle receives a transfer signal, the vehicle locates a launch ramp, and the vehicle moves to the launch ramp. A trailer attached to the vehicle moved into the water using the launch ramp, such that a watercraft can be transferred between land and water via the trailer.
