A kayak on the high seas... Isn't there a risk? Well, it depends on what kind of kayak. "Kachurka" - the lightest sailboat, the description of which is offered to your attention - is not afraid of either the expanses open to all winds or the sea wave. The survivability of the ship is ensured by the features of its design. Add to that directional accuracy and safety for crew and cargo in extreme weather conditions. Despite the elongated hull, the boat easily, as yachtsmen say, "recoups" from the waves, has good "germination" even on steep water shafts. All control systems work quickly and reliably, and the steering action is effective in any maneuver.

Yacht from a kayak

The yacht "Kachurka" has a length of 5,2 m and a midship width of 0,9 m. It is made from the usual kayak "Luch", the predecessor of the "Salute", obviously, any other kayak can be equipped according to the same principle. The impetus for this creation was the fact that a canvas folding boat under sail is too light for strong winds (it just blows away) and the hull had to be made heavier, and at the same time strengthened, increased strength. Modernization works do not require special skills and are practically accessible to anyone.

To begin with, you need a plywood veneer about 150 mm wide. The kayak should be assembled, the veneer should be placed under the soft skin to stiffen the contours.

After that, the boat must be turned over and a protective layer should be applied to its soft hull, for example, from vaseline, grease, paraffin, and then pasted over with fiberglass on epoxy resin. Four or five layers are enough for the bottom, three for the sides, and two for the deck. The stem and stern area must be reinforced with 10 layers. A steel plate 180x30x3 mm is laid in the nasal layers. An eye is cut into it - a ring Ø 40 and a cross section of 8 mm. Another metal plate with loops goes deep into the thickening at the stern - it is designed for mounting the rudder.

At the end of the gluing of the body, the veneer is removed, while the kayak acquires greater strength due to the protective shell. In addition, the air between the soft skin and the rigid hull provides the vessel with an additional margin of buoyancy. For the same purpose, 0,3 m3 of foam plastic is laid in the bow and stern parts, covered with a blank plywood bulkhead. The assembled boat should weigh about 130 kg.

The mast is installed in a regular place. Its height from the spur is 3,2 m. It is preferable to make sails from dacron or other synthetic fabric. The sail area is 3 m2, the area of underwater resistance is 6% of this value.

Behind the mast, between the two frames, a centerboard well is formed: a narrow box made of duralumin or hardboard. A hole is cut in the bottom of the boat, corresponding to the inner diameter of the box. Outside, two 50X50 mm duralumin corners are inserted into it. The box is fixed from the inside with two wooden bars 40x50 mm and tightened with bolts. Corners and overhead bars are covered with sealant. Holes for the centerboard axis and bolts are drilled in advance, before the well is assembled. The gap between the centerboard and the corners should be 2 mm.

A dowel 8 mm thick and 500 mm high is sawn out of hardboard. A stopper pin is hammered into the back of the box, on which the protrusion of the daggerboard extended to the stop rests. Cleaning - with a steel cable drawn through the block on the mast to the helmsman and locking on the duck. On the back of the well in front of the helmsman is a K-17 liquid compass.

In the bow of the hull, two duralumin loops are attached to the underdeck beam of the set (see. Fig.). The first is for the stay, on which the staysail is sewn tightly. The second is for installing the rear part of the support platform under the twist mechanism and a double block (brace wiring). The twist knot works under heavy loads, especially in the radial direction, so it must be securely fixed.

In front of the mast, close to it, on the bulwark there is a transverse duralumin pipe Ø 40 and 1250 mm long. On it are fastened shrouds on lanyards and blocks for wiring braces for spinning the staysail. The bow end spaced on both sides is also displayed on it - a nylon cable 8 mm thick. It is passed through a powerful lobe, sheathed in leather and mounted on the eye. About a meter from it to the bow end, a tight rubber cord 1 m long is tied up. Having stretched the cord as much as possible along the bow, mark this place and knit its second end here. Thanks to the rubber shock absorber, the bow slack will be gently, without jerks, selected at anchorage and during towing.

Scheme of a sailboat from a kayak (click to enlarge): 1 - fiberglass hull, 2 - foam compartment, 3 - eye-ring, 4 - twist mechanism, 5 - brace wiring block, b - twist brace, 7 - transverse pipe, 8 - mast, 9 - boom, 10 - centerboard, 11 - centerboard well, 12 - apron, 13 - steering wheel, 14 - side blocks of the brace, 15 - stoppers, 16 - bow end with rubber shock absorber and anchors, 17 - bracket for the spin mechanism, 18 - frame, 19 - stringer, 20 - soft body of the kayak, 21 - bottom stringer, 22 - overhead beam, 23 - centerboard axis, 21 - corners, 25 - bulwark, 26 - cross tube bracket, 27 - likpaza segars, 28 - lnknaz , 29 - boom guy, 30 - centerboard cable, 31 - apron skid, 32 - rubber cord, 33 - apron rib

The length of the bow is 50 m, which meets the rules for a vessel of this size. At its wet end, a fire is made with a thimble, for which a Danforth anchor weighing 3 kg or a floating anchor is attached through the lobe.

The mast is made up of two duralumin tubes Ø 30 mm, with a total length of 3200 mm. A duralumin tube Ø 15 mm, cut along the length, is attached to it on duralumin clamps-segars, which serves as a movable lipase. Outside, everything is covered with a casing of two layers of fiberglass impregnated with epoxy resin. This design ensures the correct aerodynamics of the front of the mainsail. At 700 mm from the tack, a shkertik is sewn to the mainsail, which is carried through a block under the boom to the helmsman. With it, it is easy to extinguish the mainsail in strong winds. Armor must be sewn horizontally.

The boat is protected from flooding by a movable apron made of rubberized fabric - "silver". Mounted on duralumin ribs, it easily walks along the skids along the bulwark. A rubber cord is sewn to the ribs in a stretched form, which allows, if necessary, to instantly “shoot off” the protective cover. From the front, the apron is attached to the wave baffle with screws.

The steering wheel is semi-balanced, duralumin, with a relative depth of 1: 2; pen thickness - 3 mm.

With such modernization, the kayak loses its main distinguishing quality - portability. But it turns out almost a new vessel, which has a whole range of advantages. For group trips with a large load, catamarans or trimarans can be assembled from several boats.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

The main scientific breakthrough of 2018 31.12.2018

Employees of the scientific publication Physics World announced experiments with graphene, conducted at the Massachusetts Institute of Technology, as the most important scientific breakthrough of the outgoing year.

In 2018, scientists from this institute discovered a new property of graphene. Pablo Jarrio-Herrero was listed as the head of research. It was found that graphene is capable of being both an insulator and a conductor. Moreover, the "role" depends on the angle of inclination of the location of its layers in relation to one another.

PhD student Cao Yuan, a participant in the graphene insulator and conductive graphene experiment, was also named one of the great personalities in science 2018 by Nature magazine.

Graphene is a revolutionary material that opens up huge prospects for the development of technology. It was discovered in 2004 by scientists from the University of Manchester. This material is currently known to be the most electrically conductive, lightest, and strongest carbon compound available.

According to experts, graphene is an excellent substitute for silicon. It is now known that the material melts at temperatures above 3 degrees. It is a hundred times stronger than steel and is also impervious to many gases and liquids.
