Plywood boats, made up of parts that are nested into one another during transportation, like matryoshka dolls, are light and easy to transport. Such a boat can be transported by bus or train.

We offer you two designs of "matryoshka boats".

The first one, shown in the upper left corner of our drawing, is very easy to make and weighs only 13-17 kg.

For its manufacture, you will need two sheets of 4 mm plywood measuring 1525x1525 mm, a wide pine board 1,5-2,5 cm thick, thin slats, drying oil, oil paint, tin strips 2-2,5 cm wide (can be cut from cans ) and 50mm nails.

First, cut out two blanks of sheathing 1 and blanks from boards 2, 3 and 4 from plywood, having previously upholstered them on both sides with plywood scraps. Coat the cut blanks and plywood sheets at the joints with thick oil paint, Phoenix, Unicum glue or epoxy glue.

Now nail plywood sheathing 1 to parts 2, 3 and 4. To prevent chips from forming on the edges of the plywood, pre-drill holes along the edges of the sheathing with a 2 mm drill.

The assembled bow and stern parts of the boat are connected so that the bow is 3-4 cm to the stern. Cover all joints with strips of tin, and coat the surface with thick oil paint before upholstery. After that, nail the keel rail on the bottom of the boat and the rails on the sides.

Treat the finished boat with hot drying oil inside and out, and after drying, cover the vessel with two layers of oil paint on both sides, carefully sealing all the cracks and grooves.

The bow of the boat can be made of dense construction foam, the sheets of which are glued together with epoxy glue or oil paint on natural drying oil. After that, cover the bow of the boat with two or three layers of gauze, soaking them with epoxy glue or oil paint on natural drying oil. Attach the finished nose to the nose board with two stud bolts. The aft part is also made of foam.

The oars of the boat are double, like those of a kayak. The total length of the oar is 220-240 cm. You can use ready-made collapsible metal or wooden kayak oars that are commercially available. Such a vessel has a carrying capacity of 100-110 kg.

The second design consists of four sections. Making it is more difficult and only for those who already have experience with plywood and wood. For work, you will need four sheets of 4 mm plywood.

Having cut the plywood into blanks, you must first process it on both sides with hot drying oil.

The frames use 6 mm plywood, folded in three layers. When cutting plywood, keep in mind that all body parts must be cut along the fibers of the outer layers of plywood. Don't forget to leave a small allowance for finishing the ends.

The cut parts are glued together with carpentry, casein or epoxy glue, oil paint and dried under load. For greater strength, the frames along the edges can be flashed with small nails, the ends of which are bent on the other side.

On straight sections, duralumin corners are attached to the frames. This increases the rigidity and strength of the structure. To avoid confusion during assembly, mark the blanks: the first digit is the section number, the second is the part number.

The hull parts are fastened to the frames with thin 30 mm nails, and the corners are fastened with 4 mm screws with washers.

Section I at the place of its docking with section II has a large width, so the connection is stepped. This is done so that the sections can fit one into the other during transportation. Sections are stacked in a package in the following order: I - II - III - IV; moreover, sections II and IV are turned over. For better sealing of the section connections, a rubber tube is used, which is laid next to the bolts on both sides.

The keel rail is made of parts with bevels in the direction of the vessel's movement. Reiki before fastening is pre-treated with hot drying oil and aged for 5 days.

When all sections are ready, paint them with two thin coats of oil paint. Apply the second layer after the first has completely dried. Seal the seams carefully.

Sections during assembly are connected with fixing bolts. Drill holes for them by fastening the sections together with clamps or fixing them with two or three nails.

If you have enough epoxy glue, the bottom of the boat can be pasted over with a layer of fiberglass, adding 10-15 percent acetone to the glue as a thinner. The edges of the fiberglass are bent inside the vessel and fixed there. In this variant, covering with fiberglass should be done after treatment with drying oil, and coloring - after covering.

The rear seat rests on frame 6, and the front seat rests on frame 4. The seat backs can be made movable by fixing them with clamps on aluminum tubes with a diameter of 30 mm. The tubes, in turn, are fixed with clamps on the upper bolts of the frames during the assembly of the sections.

When preparing for a water trip, be sure to provide life-saving equipment in the boat: volleyball tubes tied together, life jackets, jackets with foam inserts.

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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, ... >>

Landslide under control 25.09.2006

British scientists came up with a sensor to control the landslide.

“Every year, hundreds of people die due to sudden landslides. And many of them could be saved if they knew that a disaster would happen in the near future. Even ten minutes is enough to evacuate the inhabitants of a house in danger. and feeds the device we have developed," says Dr. Neil Dixon from Lowborough University (UK).

The device consists of a pipe stuck into the slope with a sensor that is able to collect information about high-frequency sound vibrations. Usually they are created by deep particles of soil, which suddenly set in motion. The sensor sends information to the computer, which calculates the slope stability parameters. If it turns out to be small and a landslide is imminent, the system notifies of an impending disaster.

"The places of possible landslides are usually known. Sensors installed on such suspicious slopes will help to avoid disaster: block a dangerous road in time or take residents to a safe place," says Neil Dixon.
