On rowing and sailing ships of the Middle Ages, four-legged cat anchors and two-horned anchors with a wooden rod, similar to the Admiralty ones, which appeared by the second half of the XNUMXth century, were used. On Portuguese and Spanish caravels and galleons, Dutch flutes, Venetian trabacollas and other ships, the anchors in the stowed position were suspended and fastened by a guy through a block under the bowsprit or lashed horizontally to the gunwale of the bulwark, the strength of which in the cheekbone area was increased due to additional knees.

Blocks, chain hoists, arrows, manual windlasses and wooden bollards were used to lift anchors on these ships. The mistake is made by those ship modellers who, on the model of a sailing ship dating back to the Middle Ages, make krambols and spires. The history of shipbuilding shows that these anchor devices appeared only in the second half of the XNUMXth century.

In the last century, the system of cleaning the Admiralty anchor on the ship has improved. Bulky wooden crumballs and penter beams were replaced with swivel iron cut and fish beams. Later, they were replaced by cranes, which were placed in the tank of the vessel and could freely turn in both directions. In the atom of the case, they began to make a bracket on the anchor spindle, into which the hook of the crane lifting hoists was laid. The anchor, laid on the cheekbone or on the deck of the vessel, was fastened with two chains - pertuline and rustic (for the bracket and for the lower part of the spindle).

These chains with their end links were laid in a special device on the forecastle of the vessel, called the "anchor machine", or "boatswain's rolls". It greatly accelerated and facilitated the return of the anchor. Spare Admiralty anchors were usually stored on the Pack laid flat on the deck. At the atom, the iron rod of the anchor was laid along its spindle.

On sailing ships of the XNUMXth-XNUMXth centuries, Admiralty-type anchors with wooden and iron rods, Roger's anchor and Trotman's anchor were used.

With the establishment of the Admiralty standard in 1852 (its drawings were published in "M-K" No. 4, 1980), which I embodied for myself the most advantageous proportions and forms of the best designs, a certain unification of the drawing is noted in the world production of anchors. The anchors began to resemble each other like twin brothers. Later, the anchor masters of various countries began to change the proportions and shape of the Admiralty anchor, the shape of its paws, at their own discretion.

Created in ancient times, tested by centuries of experience and brought almost to perfection, the Admiralty-type anchor is by no means completely inferior to rival designs. It can be found on modern sailing training barges and ships, on small sea vessels, lighters, fishing vessels, sports yachts and many others.

Since the middle of the last century, the Trotman anchor has also been used on many military and merchant ships.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Economic travel by electric car 14.04.2019

The driver spent just $300 to charge the electric car to travel 33 countries and almost 100 km. A typical ICE Golf car would require about 000 liters of fuel, which would cost about $6800.

The world's longest electric car journey has come to an end in Australia. Dutchman Wiebe Wakker left his home country in a modified Volkswagen Golf on March 15, 2016.

As a result, having traveled 33 countries and almost 95 km, he completed his journey in Sydney. For the entire trip, the enthusiast spent only $ 000 on charging his car, and most of it was already in the Australian outback. It has been estimated that a typical ICE Golf would require about 300 liters of fuel, which would cost about $6800.

True, it is worth noting that the trip was not only financed by donations from sponsors and ordinary people - on the way, Wacker was sometimes helped with organizing exercises and other issues. In any case, this does not detract from the achievement.

In addition, the traveler's car could travel only about 200 km without recharging, which, of course, complicated the journey, because literally every couple of hours it was necessary to charge the car.
