Manually propelled water skis support a person skiing on water. The water ski includes a base having a binding on an upper surface and stationary propulsion structures with uniform height on the bottom surface. The propulsion structures include a rearward facing and vertical propulsion surface and a forward facing and sloped surface such that drag is greater when the water ski is moved rearwardly. The propulsion surface may be arcuate, V-shape, U-shaped, or other shaped in a horizontal plane and may also be circularly concave in a vertical plane. Buoyancy structures may be secured to the upper surface of the base forward and rearward of the binding. Water ski poles including elliptically- or cylindrically-shaped floats at the bottom ends may be used to provide a synergistic increase in waterskiing speed. Straps on the base near the binding may be used to secure the water ski poles to the base in order to form an outrigger.

A stabilized flotation platform that is used for supporting supplies for those enjoying time in the water. The uniqueness is the stability provided by its construction such that materials contained on or in the device do not spill into the water.

A portable expandable device with a contracting mechanism which allows for many forms of recreational products and structures to be expanded, reinforced in the expanded shape, and then contracted easily to regain its portable form. The expansion means is exercised by the use of at least one of the following, resiliently extending, unfolding, inflating, as to become an expanding form which can then be easily retracted to the redeployed form. The retraction mechanism reverses the expansion process utilizing a mechanism which sequentially exerts the forces needed in the proper locations in order to ensure proper contraction. Disclosed embodiments utilized supplemental structural reinforcement of the expanded form through the use of joints, releasable interlocks, latching mechanisms, air bladders, to ensure the form is stable and usable. The objective being a stable structure with a rapid and easy deployment and a supplemental retraction means as to be easily transportable.
