The name of the knot comes from the word "sheet" - a special tackle that allows you to control the sail by stretching it at the bottom corners. In the sailing fleet, the clew began to be used when the latest progressive sail systems appeared. The knot is needed in order to firmly fix the sheet in the krengel of the sailcloth.
This type of knot is practical due to the simplicity of its implementation, moreover, with strong tension, the knot does not damage the cable. However, one must remember its main feature: it is effective only in cases where there is tension on the rope that is attached to the sheet. In another situation, the clew knot will simply untie.
This knot is similar in appearance to the straight knot, but they differ in the way they are woven. This type of knot is great for securing a ship's cable to a strong already tied loop. It cannot be used on ropes made of synthetic materials, as the running end will simply slide off in this case.
Besides this, the clew knot is very often used on sailing ships. Its peculiarity lies in its narrow specialization, so the node is usedonly for its intended purpose. Otherwise, most often such a mount is replaced with a bayonet or direct knot.
How to tie a clew knot
This knot must be knitted to a ready-made loop of rope or cable, as well as a chain, carabiner or metal ring.
- First of all, you need to take a rope with one free end.
- The working end of the rope is threaded into the initial loop from back to front.
- Next, the working end of the rope is wrapped around the base once.
- Finally, the end of the rope is passed between the inside of the finished loop and the main loop.
The diagram of the clew presented below will help you understand and perform such fastening without any problems.
The clew knot is one of the oldest used by man. Archaeologists have found a part of a fishing net made using clew knots, it has been dated to 7 thousand years BC. e.
And although this knot is most often used in fishing for attaching two ropes of different thicknesses, it also holds perfectly on the same ropes. It could also be a great alternative to the straight knot, were it not for the fact that it's not a connecting knot. After all, the knot must be tied with free ends, and there should be no weighting on the ropes.
The only alternative to the clew knot was the double clew knot, which is stronger and also easy to tie and untie.
It is used whensafety becomes the main condition, for example, when tying a thick and thin rope, towing, and also in cases where the cable is very large and hard, and only a straight loop can be made from it. Knit it in the following sequence:
- fold an open loop of thick cable;
- next, perform the same maneuvers as when knitting a clew knot;
- after that, a thinner rope is circled a second time behind a thick loop and again passed under itself next to the original passage;
- in the end, you need to align the knot, for this you just need to pull the thin rope and pull it off, holding the loop of the thicker cable; the little rope must compress itself; both turns are leveled by pulling the running end of the rope.
How to tie a net with a clew knot
The most famous way of weaving is the pearl net. It is simple to perform, since only light knots are used in business. In this case, the size of the cells will depend on the width of the applied shelf.
- First you need to make the main loop and fix it on the work surface with a pin. The circumference should be large and exceed the thickness of all knots at least twice.
- Next, you need to thread the hook and fasten the working thread to the bottom of the loop using the clew knot.
- A shelf is placed under the knot and a working thread is placed on it.
- Next, the working thread is pulled down behind the shelf and passed through the loop-base from the wrong side to the front. After that, the shuttle must be pulled down and the shelf should be pressed close to the clew. At the same time, the working thread is held with the thumb and forefinger in the place where it intersects with the warp.
- After that, it is necessary to perform the second clew knot and tighten it on the upper edge of the main loop.
- The work continues in the same way. In this case, it is necessary to count not the nodes, but the resulting loops.
- Starting the second row, the shelf is removed, and the whole work is turned over to the other side so that the last loop made is on the left. The shelf is placed under the loops of the first row and wrapped around it with a working thread, while directing it down.
- Then weave the second row, tying each of the loops of the previous row with a clew knot. All subsequent rows are performed in the same way, turning their work at the end of each row (you always need to move from left to right).
The clew knot is simple to perform and easy to untie, but it justifies its name - it holds the sheet tightly, while tightening strongly, does not damage the cable.
