Boat pinned in fast moving water? Learn the Z-Drag System. With a length of rope, a few carabiners, and a couple of slings you can quickly set up a simple system to free a pinned canoe, kayak or raft.
Tie a loop in the end of your throw bag and attach this to a central point on the boat with a carabiner if possible. There will be significant force so make sure the attachment point is sturdy and that the carabiner is load rated. Throw the bag of rope to shore. Loop a sling around a tree, pole, rock or some other secure object (this will be your fixed anchor) and secure the sling to itself with another carabiner. Pass the rope from your throw bag through this carabiner. Using another sling make a Prusik knot on the rope as close to the pinned boat as possible and attach a carabiner here and pass the rope through this carabiner. To ensure that you don’t lose ground once you begin pulling, add another Prusik knot to the rope between the fixed anchor and the boat, attaching this to the anchor sling with a carabiner. This will act as a brake should you lose your grip.
