Benefits: Reduce vibrations and eliminate the bumps and tugs on anchored boats caused by inelastic straps. Elastic straps keep boats secure while docked.Quick Connect: A loop and a hook on each end of the line allow for easy and quick connection. More convenient docking than traditional dock lines. These ropes are perfect for quickly and securely mooring kayaks, jet skis, pontoons, Sea Doos, canoes, speedboats, surf boats, and more.Unique Design: The tension rope is hidden in the rope, acting as a built-in shock absorber. Two EVA foam floats protect the boat from friction, and both ends are slidably adjustable for easy connection and quick hooking. And it will never sink in case of accidental landing. Double reinforcement at the internal seams.
