The Yellow Weighted Boat Lift Sling features a dying process developed specifically for the marine industry. The dyed coloring process guarantees that it will not transfer to your watercraft’s finish. The marine slings have lead weights sewn into the double kneel pad. The weights help keep the shape of the sling and help keep it from floating. However, the weights are not enough to keep adequate tension on the boat lift cable. We recommend using additional cable weights to keep more tension on the cable. 8" x 20'.
