ABSTRACT:
Shock absorber apparatus for mooring lines of boats and yachts includes an automotive type, double acting, telescopic shock absorber arranged in a two part, telescoping cage with attachment rings on each end for the mooring lines. Tensile forces in the lines caused by wave action or the like elongates and cage and compresses the shock absorber and minimizes force transfer to the yacht. Relaxation of the tensile force in the lines permits the unit to return to a neutral condition.
