How to Tie a Taut-Line Hitch Knot
There are some knots every boater should know how to tie, and the Taut-Line Hitch is one of them. It allows you to shorten or lengthen a rope or line that's under tension, without having to untie the knot. The hitch slides freely, yet jams under load. It's great for anchoring a boat to shore when the water level will be rising or falling and for securing tent and rain fly guy lines.
