Eliminates jerking and tugging on a docked boat caused by nonbungee dock lines, reducing strain on the boat, cleats, and docking area while improving overall docking stability. Builtin shock absorber design: a hidden rubber band rope inside a woven PE outer layer acts as a builtin shock absorber to absorb the maximum impact from tide or waves. The boat may bump, but the attachment stays secure, providing docking protection and enhancing safety. Easy attachment and quick docking: features a loop and clip at each end for simple, secure attachment. 316 stainless steel snap allows quick docking in about 7 seconds, even for firsttime users. Two foam floats protect the boat from scratching, and if accidentally dropped into water, it will not sink. Hidden bungee cord inside the rope: the bungee cord is concealed inside the rope and functions as a builtin snubber for additional load management and smoother docking. Use scenarios Marina docking in variable wake: use this line to minimize impact from waves and tidal action, keeping the boat steady as you approach and secure the dock. Quick, safe docking in windy or busy conditions: suitable for docks with frequent activity or lighttomoderate wind, allowing fast, confident docking with reduced hull and cleat stress. Recreational boating on lakes or rivers: the builtin shock absorption and floating protection help prevent hull scratches during routine docking, including accidental drops into the water without sinking.
