Our knot curriculum includes a section on rescue knots, which could also be labeled as moving heavy things with a rope. We teach two methods for doing so that could help you recover a stuck canoe or other heavy item: one using mechanical advantage and another using a lever. The application using mechanical advantage is called a Z drag. The application using a lever is the Flip Flop Winch. Both work well, but they work very differently. Students have to learn to set these up by themselves. Near the end of the course they are tested on it, and they can either do it correctly or they can’t. Like everything we do here, it takes time and focus to do it correctly.
