A useful knot for all sailors
Sailors, and even others, will quickly recognize the bowline knot from answer C. It is widely used on boats, because it holds on to all ropes, remains secure, and most importantly, is easily untied even if it has been subjected to strong pulls.
To make it, the nursery rhyme about the snake that wanders around and around a tree is often used: "The snake comes out of the well, goes around the tree, and goes back into the well. The chair knot is still fairly easy to do, as long as you start it off right.
Step by step chair knot
1 - Make a half-key. Be careful, the frame, the longest part of the rope, must be below the current.
2 - The current passes through the loop created by starting from below and exits the loop.
3 - While still guiding the current, we pass under the sleeping bag. It is there that in the rhyme, the snake makes the famous "turn of the tree".
4 - Finally, the current returns to the starting loop from above.
5 - Once tightened, you have in your hand a splendid chair knot!
