Poly rope is more buoyant than other ropes made from materials such as nylon and natural fibers. A suitable alternative for many uses, poly rope is often used in activities that take place on or near water. Poly rope, in addition to being buoyant, resists moisture and rot. Various knots are tied with poly rope and one in particular is used to temporarily tie up watercraft.
