Steep Creek Rescue unpinned a boat in right Crack on section 4 of the Chattooga during a Halloween paddle. I was running this section for the first time, but was with a good crew. While we were scouting Jawbone, we noticed that the crew behind us were having some trouble at the Crack rapid. A boater had dislocated his shoulder and had to swim to the bank. He was safe, but his boat pinned in right Crack. I had all the gear on me so a buddy and I proceeded to set up a haul system. A 3:1 zdrag was able to unpin the boat fairly easy.
