A pinned boat can ruin our day on the river, which is why we picked up the NRS Z-Drag Kit. This kit includes all the carabiners, pulleys, tubular webbing, and cords necessary to set up a 3:1 mechanical advance to un-pin a large, heavy boat-- along with a crib sheet that illustrates the 3:1 Z-Drag. This package includes 150 feet of rope, 3x Nuq Screw Lock Carabiners, 2x SMC 2in Swiftwater Pulleys, 2x 15ft pieces of Red 1in Tubular Webbing, 1x 10ft piece of Yellow 1in Tubular Webbing, 2x 6in pieces of 6 mm Prusik Cord (8 mm for Static Kit), 1x Z-Drag Rescue Crib Sheet, and 1x NRS 40L Purest Mesh Duffel Bag. We can choose between a 3/8in Sterling NFPA Grabline Rope (3282 pound strength) or 1/2in Sterling HTP Static Rope (9081 pound strength).
