Abstract: A series of simple detachable frames, fitted between a floating body and its' mooring support structure, will provide static stability to the floating body, by restraining all movements--except those occurring vertically under tides and buoyancy lift, and to which movements it will provide vertical guidance. Called "Stabilizer for Floating and Submersible Structures," many uses are anticipated for the device. Among these are: pontoon lift docks, where it will eliminate the need for winches and their lift cables or chains, as well as their support piers; ocean-bed exploratory structures, where it will create a new type of stabilized oil-drilling platform and transfer shuttle; and for water craft at mooring, a safer securing system to replace conventional mooring lines.
