Abstract : The patent relates to a tethering arrangement for a water-borne object which is effective to absorb forces tending to cause positional displacements thereof and subsequently use the energy so absorbed to return the object to its original location. In a preferred embodiment, one or more elongate members each has a predetermined elasticity factor connecting the floating object to a fixed sub-surface point or structure. The overall length of each such member varies in accordance with the stresses imposed thereon by virtue of weather conditions and/or other environmental factors to which the floating object may be subjected. In addition, the constant flexing of the elastic members greatly inhibits the growth of marine organisms on the surface thereof, as well as eliminating the cyclic stress which leads to the failure of steel components due to work-hardening.
