Tying a rope is one of the most practical skills to have in your arsenal, and 99 percent of the time, a bowline is the best knot for the job. Not only does it offer a rock solid hold, it can be tied and untied in seconds, even after bearing tension. 1. Create a loop. 2. Create a second loop behind the first and partially feed it through that first loop. 3. Pass the end of the line (fed through whatever you're hitching) through the tip of the second loop. 4. Tighten.
