ABSTRACT:
The disclosed portable docking/support system has a frame structure including end stands and elongated members connected at opposite ends thereof to and between the end stands. The elongated members include a pair of upper members and a lower member spaced below and laterally between the upper members for strengthening the frame structure. The upper elongated members are laterally spaced apart a distance less than the hull width of a personal water craft to be docked relative to the system and are extended lengthwise at least a portion of the hull length. The end stands have optional structures (casters, wheels or end plugs) suited to be rolled on or rested on a generally horizontal support surface (under water on a lake or river bed or on a nearby beach or land). The upper elongated members are spaced apart horizontally and are vertically higher than the end stands at all locations laterally between the upper elongated members. In use, with the end stand structures rested on a river or lake bed support surface, the upper elongated members will be proximate but generally below the water surface, operable to allow a water craft to be substantially floated lengthwise between and onto the upper elongated members and into a supported or docked association therewith. The frame structure is formed of lightweight plastic piping for allowing it to be manually moved about as needed and for durability in and out of water.
