Flat knot. Travel Tips

Tourist tips

Name "flat knot" got into our maritime language from French. It was introduced for the first time in his "Dictionary of Marine Terms" by the famous French shipbuilder Daniel Lascalier in 1783. But the knot was, of course, known to sailors of all countries long before that. What it was called before, we do not know. It has long been considered one of the most reliable knots for tying cables of different thicknesses. They even tied anchor hemp ropes and mooring lines.

Having eight weaves, the flat knot never tightens too much, does not creep and does not spoil the cable, since it does not have sharp bends, and the load on the cables is evenly distributed over the knot. After removing the load on the cable, this knot is easy to untie.

The principle of a flat knot lies in its shape: it is really flat, and this makes it possible to choose the cables connected by it on the drums of capstans and windlasses, on the welps of which its shape does not interfere with the even overlap of subsequent hoses.

In marine practice, there are two options for knitting this knot: a loose knot with tacking of its free running ends to the root or half-bayonets at their ends (Fig. 29, a) and without such a tack, when the knot is tightened (Fig. 29, b). A flat knot tied in the first way (in this form it is called the "Josephine knot") on two cables of different thicknesses almost does not change its shape even with very high traction and is easily untied when the load is removed. The second knitting method is used for tying thinner than anchor ropes and mooring lines, cables, with the same or almost the same thickness. At the same time, it is recommended to first tighten the tied flat knot with your hands so that it does not twist with a sharp pull. After that, when a load is given to the connected cable, the knot crawls and twists for some time, but, having stopped, it holds firmly. It is untied without much effort by shifting the loops covering the root ends.

Rice. 29. Flat knot: a - the first knitting method; b - the second way of knitting

As already mentioned, a flat knot has eight weaves of cables and it would seem that it can be tied in different ways - there are 256 different options for tying it. But practice shows that not every knot from this number, tied according to the principle of a flat knot (alternating intersection of opposite ends "under and over"), will hold securely. Ninety percent of them are unreliable, and some are even dangerous for tying cables designed for strong traction. Its principle depends on changing the sequence of intersection of the connected cables in a flat knot, and it is enough to slightly change this sequence, as the knot gets other - negative qualities.

In many textbooks and reference books on maritime practice published in our country and abroad, the flat knot is depicted in different ways and in most cases incorrectly. This happens both due to the negligence of the authors, and due to the fault of the graphs, which, redrawing the knot scheme from the author's sketches in one color, cannot always make out whether the end passes over or under the other end. Here is one of the best forms of a flat knot, tested and tested by practice. Other valid variants of this node are deliberately not given by the author so as not to scatter the reader's attention and not give him the opportunity to confuse the scheme of this node with any other. Before putting this knot into practice for any important business, you must first remember exactly its scheme and tie the cables exactly along it without any, even the most insignificant deviations. Only in this case, the flat knot will serve you faithfully and will not let you down.

This marine knot is indispensable for tying two cables (even steel ones, on which a significant effort will be applied, for example, when pulling a heavy truck stuck in mud on half a wheel with a tractor).

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Bottle furniture 06.08.2003

Richard Liddle of the University of Newcastle, England, has developed a way to turn discarded plastic bottles into durable material for modern furniture. Recycled plastic is opaque, can be dyed any color, and can be molded, stamped, or extruded into any shape.

Liddle founded his own company and intends to start making office furniture out of bottles - tables and chairs. If the novelties go well, production will expand.
