A watercraft includes at least one floating member, a central frame supported thereon, first and second foot platforms, and first and second handlebars. The first and second handlebars define elongated configurations and include grasping end portions, intermediate portions pivotably coupled to the central frame, and base end portions pivotably coupled to first end portions of the respective first and second foot platforms. A propulsion system includes an axle assembly, first and second rotating arms, and first and second oars. The rotating arms are fixed relative to one another, pivotably coupled about the axle assembly at first ends, and pivotably coupled to second end portions of the foot platforms at second ends. The oars are engaged with and extend from the foot platforms. The propulsion system cycles the oars approximately 180 degrees out of phase to propel the watercraft while maintaining substantially perpendicular orientation of the oars.

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 buoyant pool lounge chair frame and buoyant pool lounge chair using the same are disclosed. In one embodiment of the buoyant pool lounge chair for supporting a person while the buoyant pool lounge chair is floating in water, frame members collectively form at least one of a seat frame, a leg frame, a back frame, a left arm frame, and a right arm frame. The frame members include multiple frame segments which are steel coated with a first vinyl polymer coating to provide steel-to-vinyl contact. Buoyant cushions are attached to the frame members. The buoyant cushions are coated with a second vinyl polymer coating. An adhesive coating is interposed between the first vinyl polymer coating and the buoyant cushions.

A method for adhering a label, lettering, ink, a tattoo, sketch, design or color (“indicia”) to a substrate comprising the steps of: providing an indicia-bearing backing paper; moistening the indicia-bearing backing paper to form a moistened indicia-bearing layer; providing an adhesive layer between the moistened indicia-bearing layer and the substrate; placing the moistened indicia-bearing layer on the adhesive layer; allowing the indicia to become separated from the backing paper, leaving the indicia upon the substrate; and drying on the substrate.

A universal cover for a water mat is provided. The universal cover has a top cover portion and a bottom cover portion that can be secured together with zippers. The bottom cover portion has a plurality of parallel buoyant bars and the top cover portion has metal structures to securely hold magnetic accessories.
