The dock line is made of 100% high-strength nylon. The double braid construction is ideal for docking, o ering reduced stretch while providing increased shock absorption. Our dock line features a large 12-inch spliced end loop, making it easy to attach to a dock or your boat's cleat. When docking your boat, it’s essential to limit the movement of your watercraft while absorbing the shocks created by waves. Our dock lines provide low stretch and high shock absorption, ensuring that your pontoon stays securely tied at a marina or gas dock without the need for a lift.
