Any watercraft, whether it’s a flat boat, a boat or a yacht, gives some sense of freedom, which is now accessible to many. It would seem that more recently, home-made boats made of plywood have just reached their peak of popularity, but since then there have already appeared a lot of ways to perform such structures and methods for processing plywood products.
Since the proposed design will be small, building a boat out of plywood will not cause any difficulties. It is enough to stock up on materials and tools, as well as make the appropriate calculations.
Description of the necessary materials and tools
The advantages of such material as plywood are not worth listing, since many have probably already encountered the advantages of plywood products.
Note! Projects of boats made of plywood are made of material of the FSF brand. The thickness of the sheets used varies between 0.5-1.5 cm, depending on the purpose of the structural part that will be made of them.
FSF brand plywood products are characterized by a high level of resistance to moisture. However, in the process, your cabin plywood boat will be further processed, and more than once. Pay particular attention to the quality of the material when purchasing it. The surface of plywood sheets should be completely free from any defects, damage in the form of cracks and chips, as well as delaminations and all kinds of knots that are often found on wood. This moment is extremely important, because the final result of your work, as well as the reliability of the structure itself, depends on the quality level of the material.
Specialists who have already had to deal with a task such as making a boat from plywood will say that working with a large sheet is much more convenient and convenient, and therefore faster. Therefore, give preference to large-format plywood products.
Supporting materials:
- Edged trimmed wood, which is needed to equip seats, internal struts and sides. To make a functional boat out of plywood, give preference to light wood.
- A plastic clamp or thin wire, which will be used as a suture material for joining together various parts belonging to the boat skin. You can use a fishing line from kapron, but in this case it should have a decent thickness.
- Adhesive for sealing joints formed at the joints of parts. It is best to use a mixture of polymer resins.
Of course, people who know how to build a boat out of plywood can add other materials to this list. But in this case, an example of a minimal set of additional materials is given. Most often, various varnishes are used as supplements, as well as specialized impregnations that prevent decay and swelling of a structure that has been in contact with water for a long time.
In addition, for gluing seams between parts, you may need a material such as fiberglass, which can be replaced by its analog - fiberglass.
And of course, do not forget about the external aesthetics of your product. For this, paint is also suitable, which will allow you to hide all the seams and achieve the desired color.
The tool kit is standard in almost every case:
- electric or manual jigsaw;
- a set of canvases of various sizes attached to a jigsaw;
- saw designed to work with wood;
- sander;
- pliers;
- brushes for various purposes: for applying varnish, staining, impregnation;
- hammer;
- chisel.
As for the dimensions that a plywood boat can have, the design drawings can be very diverse, so you can hardly advise anything concrete.
However, you can focus on standard sizes:
- total long construction - 3.5 m;
- boat width - 1.35 m;
- side height - 0.5 m.
Having picked up a suitable design drawing, it is necessary to transfer all the details to plywood, after which the sheet is cut according to this marking. To perform this task, you need an electric jigsaw, as other tools can damage the material, and the cut line will be uneven, with chips.
Since in our case the boat is running, its transom must be glued with an additional layer of fiberglass and, if possible, strengthen its structure. For this, you can use boards made of hardwood. In addition, self-tapping screws will help you to strengthen the fasteners.
Note!If you have not yet fully figured out how to make a boat out of plywood, follow the advice of professionals: the stage of designing and calculating the carrying capacity is very important, because having made a mistake with the basic parameters of the vessel, the result of your work can hardly be called functional.
With regard to practical recommendations, then before assembly, all structural elements should be finalized with a planer. Most preferably, an electric tool will be used. After that, you need to make the corresponding holes, which will be used later, when you will stitch together the hull of the boat.
To facilitate the installation of the transom, you can use special goats that are easy to build yourself. Then the bottom is fixed, then the side parts of the boat.
Note! These details necessarily come down to the bow. Remember to check the arrangement and symmetry.
Sheathing details and sheathing material itself can be fixed in two different ways. In the first case, this can be suture material, in the second case, a special adhesive can be used. In the process, you will have to manually set the butt edges of the plywood, while achieving a certain angle.
It is necessary to constantly monitor the conformity of sizes, otherwise, as a result, you may have a large gap between the parts, to eliminate which you will have to not only cut the frames, but also disassemble the entire structure.
Frames - rib-shaped parts, due to which the required level of rigidity of the frame of your boat is achieved. These parts are cut out of plywood sheets 6 mm thick and installed in 0.8 m increments. In the end, you should get 4 pcs.
Do not underestimate the importance of such a detail as a girder located along the side of the board. It may have an external or internal placement. If you stock up on clamps, then these devices can provide you invaluable assistance and greatly simplify the work. If you do not have a sufficient number of clamps, it is advisable to fix at least control points with them when pressing the fender bar. It will not be superfluous to use binders that can be placed between clamps.
After completing the above work, you can proceed with the installation of the frame. If you are not afraid to take risks and have at your disposal fragments of plywood residues, this part can be made not whole. The main thing to remember is to form a hole in the middle of the frame.
If you cover this area with a deck, you can end up with a small enclosed area that can be used as storage for things. On the manufacture of the deck, you can also put the remains of plywood.
If you want to learn more about how a plywood boat is made, the video review below will help you understand all the intricacies of this process.
Carrying out internal and adhesive work
For glue work, you will need to prepare a mixture consisting of epoxy resin and aerosil mixed in equal proportions. The corner zones of the bottom, transom and sides should be strengthened with a wooden fillet or corners.
Fiberglass tapes are glued to the zones of the internal seams using the previously prepared mixture. They are also used for fixing frames.
At the end of the gluing work, the flooring, seats, oarlocks and other details that may be provided for in your project of the vessel are mounted.
After that, the structure is left to dry, and then all external work is performed to clean and paste the seams with fiberglass.
To qualitatively perform the coloring should:
- perform a surface degreasing procedure;
- coat the material with a special composition;
- putty to eliminate all errors, if any;
- apply a primer coat.
The coloring composition can be absolutely anything, but it is most preferable to use a pigment dye designed for working with wood. Using brushes instead of a spray gun will improve the staining result.

Boat description
The main purpose of this vessel is it is a comfortable stay in the open spaces of St. Petersburg and the Gulf of Finland. For its size, the boat has an exceptional internal volume, including 3 comfortable cabins for long trips, a spacious lounge with a breakfast bar, comfortable sofa and table, kitchen, toilet, cabin for 12 people with panoramic windows. In addition, the boat has a large open deck and aft platform, where our guests can sit with maximum convenience, in the open air. The boat has unrivaled maneuverability and low draft, allowing you to approach close to the sandy beach. The seaworthiness of this boat allows you to go to the Gulf of Finland and Lake Ladoga.
For a comfortable stay, the boat has a barbecue for preparing dishes on charcoal, a functional kitchen with an induction hob, fridge, sink. Spacious bathroom with shower and washbasin. On board there is a voltage of 220 V, an audio system, a TV. The boat has a spacious aft platform with a ladder from which it is convenient to dive into the water. If you or your children want to relax or just lie in silence, admiring the water through the portholes, there are 3 separate cabins.
Once we had to take a tugboat “monophonic” with a displacement of 6 tons in a tugboat “Killer whale” equipped with a 30-horsepower “Whirlwind”. To everyone’s surprise, despite the fact that a high-speed propeller and a “Whirlwind” were clearly installed on the motor He didn’t give his full power, the towing speed was about 6 knots, that is, he did not differ much from the normal speed that the sailboat develops with an average wind. It was then that the idea came to replenish a number of projects recommended by the editorial board for self-construction, with drawings of a fairly comfortable and relatively large tourist vessel, designed to sail in a transitional to planing mode with an outboard engine with a capacity of 25-30 liters. from. The results of the study and are presented to the court of amateur shipbuilders as another project of a boat for self-construction.

When developing the project, it was based on the main requirement: to ensure the convenience of a crew of four on board during long voyages on inland waterways. On the boat "Walrus" the crew is located in two cabins, separated from one another by a bulkhead.
General location boat "Walrus"
1 - removable cover of the engine compartment; 2 - the folding part of the niche bulkhead; 3 - side pockets; 4 - awning; 5 - masthead fire; 6 - glass; 7 - sliding sunroof; 8 - manhole cover, fiberglass; 9 - ventilation hatch; 10 - a shelf for small items; 11 - double cross bollard; 12 - nasal railing; 13 - zygomatic splash guard; 14 - locker or fresh water tank; 15 - sofa, under it is a locker; 16 - removable table; 17 - a folding seat for the driver; 18 - mooring duck; 19 - removable can; 20 - mooring cross bollard; 21 - steering wheel with a diameter of 300 mm; 22 - galley table; 23 - gas stove; 24 - sink; 25 - wardrobe; 26 - a berth, below a locker; 27 - door to the cabinet in forepeak; 28 - locker.
The bow cabin is sleeping and can be used to relax constantly, including on the move during the daytime. Here, in the lockers under the V-shaped bed, you can place part of the traveling supplies of provisions and equipment. Personal items are stored in a cabinet behind the forepeak bulkhead and on shelves mounted on the sides under the deck. In the bow cabin it will even be possible to stand upright, bending the head slightly; a small area of \u200b\u200bthe priest is enough, for example, to change clothes. The hatch in the roof of the cabin provides good ventilation of this small-sized room, and can also serve as an emergency exit.
The second cabin serves both the wardroom and the galley. At night, the stop is removed; with the help of additional support rails and soft sofa backs that fit on them, the longitudinal sofas turn into one double bed.
It is easy to make a folding seat, which will increase the length of the bow sofa for lunch; if you put a couple of folding canvas chairs in the aisle, you can place at least six people at the table.
The starboard cabin equipment can be made to your liking. The drawing shows, in our opinion, the best option with a large cutting table, double burner gas stove and sink for washing dishes. The volume of the galley foot is large enough to store dry provisions and the main part of the galley utensils in it. Under the sink, you can put a garbage bucket; drain from the sink should be done directly overboard.
If desired, instead of a wardrobe, you can equip a toilet, but the purchase or manufacture of a toilet with forced pumping remains a difficult problem today.
The space under the seats is used to store bedding and parts of clothing.
The height in this cabin from the floor to the edge of the beams is 1.75 m; it can be ventilated through the sliding windows in the cabin coaming.
The advantages of the "Walrus" include the "full-sized" cockpit with an area of \u200b\u200b2.7 m². In good weather, experience shows that it will be the main place the crew stay on the go. In addition to the driver's seat, there is a stern removable can, the same canvas high chairs can also be used. The rigid arc above the cockpit is not only a detail of the exterior of the vessel, but also serves as a permanent basis for fastening the awning. Awning is best done in two parts: the bow, which closes the driver's post and the entrance to the cabin, and the stern, which will be needed only at the time when someone is in the cockpit. By the way, the dimensions of the cockpit are such that, if necessary, you can equip a couple of berths here by laying air mattresses.
The space on the sides of the niche can be used to accommodate skipper equipment, spare gas cylinders, rescue bibs. Niches are provided on the sides of the cockpit, where fishing accessories, cables, a lantern, etc. can be put. To reduce noise from a running engine, the niche is closed by a removable lid. Bulkhead on sp. 7 it is necessary to provide a reliably closing hinged upper part, which makes it convenient to service and repair the engine afloat and at the same time allows you to maintain the full height of the side in the stern.
The design of the boat focuses on providing comfort and seaworthiness that can be really guaranteed with one 30-horsepower outboard engine. It is assumed that the owner of such a vessel will not, for example, enter a large reservoir at a wave height of more than 0.6 m and a wind speed of more than 7 m / s. It's not that the boat is not stable enough or has poor germination to the wave. There are two reasons for this limitation on seaworthiness. The first is the likelihood of the engine being flooded with a wave: after all, the carburetor is located only 550 mm above the surface of calm water, and our industry does not yet produce motors with a “long leg” and an airtight pan that are installed on such boats abroad. The second - this is only a small margin of emphasis developed by a high-speed propeller of small diameter. Therefore, in bad weather, a vessel with a high freeboard and a well-developed superstructure will be difficult to rake against a strong wind and a high wave or to stay on course in a crosswind.
The hull contours are designed for the normal speed of the boat under one engine 18-20 km / h. This corresponds to a Froude number of 0.7. Such relative speeds are characterized by the appearance of significant hydrodynamic forces of support in the feed, although complete separation of the flow from the transom has not yet occurred. Therefore, to reduce the turbulence behind the transom, a smooth rise of the bottom in the stern to the waterline is provided, so that the boat transom is only partially submerged in water. The transom has a horizontal bottom section, which will help to reduce the running trim when driving at maximum speeds that can be developed at the smallest load (on an empty boat) or when installing a second motor.

In accordance with the accepted concept of limiting seaworthiness and ensuring maximum comfort, the line of the cheekbones in the bow has a relatively small, moderate rise. This allows you to get a larger volume of the bow cabin and simplifies the construction of the hull of the boat.
An important role is played by the fin on the aft half of the bottom: it increases lateral drift resistance, contributes to the stability of the boat on course in the fresh wind.
The total displacement of the boat when going out with four people, full camping equipment on board and with a fuel reserve of 150 km (about 90 liters) will be about 1,400 kg. With such a load, a propeller with a pitch of 230-240 mm and a diameter of 240 mm (for Vortex-M and -30) is optimal for full engine power output. The regular screw in this case is absolutely unsuitable, since swimming with it will take place at a reduced speed and excessive fuel consumption.
When installing a second engine (total power of 50-60 hp), you can expect an increase in speed to 30 km / h with a fuel consumption of about 0.9 l / km. In this case, both regular screws and screws with a pitch of 280 mm can already be used. But, we repeat: the contours are chosen optimal for lower speed, therefore, with a twin-engine installation, it will be necessary to take a number of measures to reduce the running trim of the boat. To compensate for the effect of the shift of the center of gravity in the stern, you will have to move some heavy loads into the bow, for example, place a fresh water tank with a capacity of 60-70 l under the bow deck. It will be necessary to install transom plates (see the manual “Boats, Boats and Motors in Questions and Answers.” L., “Shipbuilding”, 1977) or to make wedges on the bottom of the transom.
Those who from the very beginning expect to use the boat mainly with a pair of 25-30-horsepower motors should change the contours of the stern of the hull in advance: increase the draft of the transom and, accordingly, reduce the rise of the bottom in the stern, maybe slightly increase the pitching of the bottom.
Although when navigating in transition mode, the weight of the vessel has a smaller effect on speed than with clean planing, it is still necessary to make the hull quite light: the available capacity is 30 liters. from. - not so great! If the bottom will not be glued with fiberglass, it should be sheathed with 8 mm plywood; good quality FSF plywood. When pasting the case (two layers on the bottom, one on the sides), 6 mm plywood on both the bottom and sides is enough.
It is proposed that the Morzh boat hull be built with a longitudinally-transverse recruitment system with a relatively small number of frames, which with the transverse system take up a lot of usable volume inside the vessel, significantly increase the weight of the hull and the complexity of the construction. In this case, the basis of the transverse set, which defines the shape of the hull, is a transom, three bulkheads and only four frames assembled from pine slats with a section of 22X60.

It is proposed to make bulkheads between cabins and cockpit with double plywood stitching: with this design, good sound insulation, and the necessary strength, and a good appearance of the bulkheads are achieved (especially if decorative plywood is used). The same plywood will need to be sewn up on the spaces in the cabins, using a girder and side stringers as a lath for fastening sheets.
The advantages of a design with a large number of longitudinal bonds include the fact that thin sheathing is divided into rectangular sections - panels of relatively small sizes (for example, bottom sheathing panels have a size of no more than 925X300 mm). Consequently, in the event that the bottom touches an obstacle, say, a firewood or stone, the force of the impact will almost always be accepted by a rigid stringer or frame, the case will end with a crack in the skin, and not a through hole, more likely with a significant width of the panels (it is clear that in field conditions, repairing a hole will be more difficult).
It is best to assemble the hull on a slipway upwards with a keel from preassembled knots of bulkheads, frames, transom and stem. The technology of work is described in detail in previously published articles (a book by Yu. Kazarov and N. Sokolova “Journey on“ Boats and Yachts ”, L.,“ Shipbuilding ”, 1978, which has a special index of publications on issues buildings of the hull), as well as in the book “15 projects of ships for amateur construction”, which is well-known to amateur shipbuilders.
Insufficiently experienced shipbuilders may have difficulty in manufacturing bent glued stem and plywood sheathing the bow of the boat bottom. When cutting the sheets of the bottom, we recommend starting with the preparation of the nasal sheet. When laying the sheet on the set, it is necessary to orient it in the direction of the fibers of the outer layers of plywood so that the sheet is easily bent and fits snugly over the entire width of the edges of all parts of the set. In extreme cases, you can slightly trim the edge of the flortibber or, conversely, stick an additional rail on it to get rid of the gap.
After turning over the hull, it will already have a base in the form of bulkheads on the sp. 3 and 5 to form the cabin. Having cut out the grooves for the carlengs and putting them in place, you can lay a deck of plywood 6 mm thick, and then put on the edges of the cut for the cabin and cockpit the bars of the outer carlengs, to which the coaming of the cabin along with the shelves - supporting rails for the beams of its roof are attached.
B - construction of a pattern for beam roof and beam beams (C - width of the roof or deck; f - arrow of death; K - upper edge of the coaming of the cabin; LB - side line).
All open edges of plywood must be carefully protected from moisture with the help of glazing beads or fiberglass strips on epoxy resin. In the nose, it is necessary to install a zygomatic splash guard, which will reduce the flushing of the sides by the nasal wave and splashing of the cockpit when swimming in windy weather. On the aft third of the length of the boat hull, it will be useful to protect the sideboard from damage during mooring by setting a fencing beam approximately in the middle of its height.
The wooden case itself has a margin of positive buoyancy, which is necessary in emergency cases, for example, when breaching a hole. However, to compensate for the weight of the motor and the cabin, which should remain above the water, as well as to create an additional margin of buoyancy, it is advisable to lay about 200 dm³ of light in such places as the space between the bottom and the engine recess, between the side and the inner stitching of the cockpit, in the forepeak under the cabinet polystyrene foam. Then the boat will stay afloat with all six passengers sitting in the cockpit. It is advisable to place the foam higher - closer to the fender and at the ends of the hull so that the boat does not roll over when filled with water.
A certain advantage of relatively low-speed tourist vessels is the possibility of their round-the-clock movement: on the one hand, breaking the crew into two shifts, you can ensure normal rest even while the boat is running, on the other hand, collisions with floating objects are less dangerous. Therefore, during the construction of the "Walrus" you need to take care of the appropriate equipment of the boat with signal-distinctive lights and their power sources. If the boat is supposed to be used for sailing on small rivers with a limited overall height of the passage under the bridges, you will have to abandon the U-shaped rack of the awning above the cockpit, and make the glass on the roof of the wheelhouse collapsible. This will reduce the overall height of the vessel from the waterline from 1.1 to 1.75 m.
(Ending. Beginning at No. 5, 1975)
In the previous issue we talked about the new boat, created in our public design bureau. Combining the best traditions of domestic small shipbuilding and new trends, this boat attracted our attention with the perfection of forms, comparative ease of manufacture and accessibility of the materials used. So, again, Ruslan.
The hull is assembled upwards by keel on a slipway of two wide boards 40–50 mm thick placed on a rib (Fig. 1). Such a slipway is sometimes called a frame, because it really is a rigid frame, which provides greater accuracy in the installation of frames, longitudinal elements of the set and the convenience of work when sheathing the frame with plywood. In the process of performing operations, the frame slipway can be rearranged, turned over many times without risking disrupting the position of the set, etc. The method of assembling the hull on the slip from one board placed on an edge mentioned in some manuals is outdated.
Have you long dreamed of visiting a pleasure boat, enjoying the picturesque landscapes of the northern capital that open during excursions along the waterways of St. Petersburg? Renting a motor ship is a great opportunity to have fun in a good company, such a vacation will give positive emotions and will cost relatively cheap.
Markings for grooves should be made on the slipway with great accuracy, in which, when installing the frames, the shergen strips (see Fig. 1A) are included, which are fixed in place (after alignment) with nails or small wedges. Experienced builders usually glue the shergen planks tight, which provides the kit with greater rigidity.
It is advisable to strengthen the frames after installation (see Fig. 1B) with temporary longitudinal struts and braces. This will ensure the perpendicularity of the frames with respect to the DP and will help to avoid distortions that occur when installing the elements of the longitudinal set.
The next operation is the insertion of longitudinal elements (see Fig. 1 B). It is conducted in the following order: 1 - keel with stem, 2 - girders, 3 - zygomatic stringers, 4 - side stringers, 5 - bottom stringers. The marking of the grooves for the insert is carried out in place with the help of a long flexible rail superimposed simultaneously on 2-3 frames. The rake helps to detect inaccuracies and correctly produce a little.
Malkovka consists in removing irregularities and protruding corners of individual elements of the frame so that the casing fits evenly and tightly to it, without distorting the shape of the housing specified by the drawing. Malkovka is carried out by small-sized planers, chisels and rasps. The strength and appearance of the product depend on the thoroughness of its implementation.
The casing of the Ruslan case with plywood has its own characteristics. The fact is that the side panels, hanging down, form the outer walls of the sponsons. Therefore, first, the central part of the hull should be sheathed, with a small allowance for processing, and only after that - the sides, with an overhang of the appropriate size. Then, foam is glued under the overhang, forming (starting from frame No. 2) a tunnel between the sponsons and the middle part of the hull (see Fig. 1 D). It is best to build plywood according to pre-made templates from kraft paper or thin cardboard.
The fastening of the skin to the frame begins from the transom towards the nose. The connection of the sheets is carried out "on the mustache" directly on the frame or in advance.
A - the main dimensions of the slipway; B - installation of frame frames using shergen-slats (frame No. 1 and transom board are attached with screws directly to the end walls of the slipway); B - inset of the longitudinal elements of the frame (keel, fenders, cheekbones and dairy stringers) G - casing of the frame with plywood; D - pasting the finished body.
The plywood is attached to the frame as follows: with “nibbling” nails to stringers and screws 20 mm long - to frames and keel (see Fig. 1E). Before applying plywood, the frame is carefully coated with epoxy glue. At the end sections of the parts, the glue is quickly absorbed, and the spread has to be repeated. The heads of the nails used to attach the plywood to the frame are pre-flattened so that they can be “drowned” in plywood - otherwise they will tear the fiberglass with which the body is glued. The screw heads should also be recessed 1-2 mm, depending on the thickness of the plywood.
Having sheathed the hull completely, they begin to paste the tunnels with foam. First, pieces that approximate in shape are pasted. Final processing is carried out after adhesive polymerization. Small irregularities are smoothed out with mastic from sawdust with epoxy resin.
The sequence of gluing the case with fiberglass fabric: first, they are edged with narrow strips, and after polymerization, the corners and ribs on the joining lines are carefully cleaned. Then paste over the entire surface with one layer of ASTT-B fiberglass. Longitudinal edans are installed in place and carefully pasted over with strips (or tapes) of fiberglass.
The case is painted on soil No. 138 or AG-10 with epoxy, glyphthalic or nitrogliphthalic enamels using conventional technology. Alkyd imported enamels that have recently appeared on sale have proven themselves well.
MANUFACTURING ADJUSTMENTS
The framework of the superstructure (cabins) is the framework (Fig. 2) and longitudinal rails (stringers) assembled on glue and plywood knits. The lower part of the frames (“legs”) is connected to the frame frames of the body, as shown in Figure 3, thus providing the necessary rigidity of the entire structure. After the gluing of the superstructure frame is completed, it must be grinded and prepared for sheathing with plywood (no more than 3-4 mm thick), otherwise the superstructure will turn out to be excessively heavy. Typically, the superstructure is sewn up with plywood deaf, and the cutouts for glazing are made already in place with a narrow circular hacksaw; we recommend this method.
1 - the central pillar of the windshield, 2 - the harness of the front of the roof, 3 - the boss, 4 - the solid frame of the superstructure on the frame No. 3, 5 - reinforced stringer along the contour of the roof opening, 6 - the corner stringer, 7 - the rack on the frame No. 5, 8 - stand on the frame No. 6, 9 - door frames, 10 - bulky bulwark, 11 - plywood knits connecting the superstructure frame with the timber frames. 12 - stringer along the contour of the glass, 13 - side stand of the windshield, 14 - harness of the windshield, 15 - midsection. A - glass insert on a rubber seal; B - glass insert using plywood frames; In - an easily removable steering wheel with devices.
Do not insert ordinary glass into the openings of the superstructure; it is better to use triplex or plexiglass. For windshields, this requirement is mandatory. Glasses are inserted on a rubber sealant, as shown in Figure 2B.
On windshields it is necessary to establish "wipers" - screen wipers with electric or manual drive. Practice has shown that it is better to put them on top, since waterproofing is complicated when installed from below.
Outside, the entire superstructure should be glued with a single layer of thin fiberglass on epoxy. This is best done before installing the glasses; if gluing is done after, the glass should be protected from resin by gluing wrapping paper on them with grease.
The sliding part of the cover consists of a light wooden or metal frame, sheathed with plywood 4 mm thick. The transverse bars must be curved so that the lid is slightly convex, as shown in the drawing. If desired, it can be made not movable, but removable or opening on hinges; it largely depends on swimming conditions.
The location of the controls and interior equipment of Ruslana is shown on the layout and drawings. The steering wheel is located on the DP line, this allows the installation of motors with any direction of rotation and is especially convenient when towing skiers when the driver needs freedom of movement. Steering wheel "Ruslan" traditional for OKB "MK" functional type, easily removable, with a combination of devices in the hub (Fig. 3). The electric tachometer is equipped with a switch that allows you to measure the speed of both motors in turn. The speed indicator is made on the basis of a small gauge at 1 At (GOST 53125). Two connectors are mounted on the steering wheel: one, eight-pin, type ШР, for electrical system wires, and the other for the speed indicator receiver (durite tube with an inner diameter of 3 mm). The large diameter steering drum provides a very low rudder consumption (deviation), making the boat responsive and enjoyable.
In addition to the aforementioned devices, toggle switches of the electrical system are located on the steering wheel hub: in the center - the indicator of the pulse signal, and on the common panel - switches for navigation lights, searchlight and engine ignition. A bundle of wires with three outlets is installed inside the add-in to turn on a portable lamp or small lamps mounted on a plug. A radio receiver of the “Geologist” type (the most moisture-resistant model among domestic transistor receivers) and a “Shilyalis” TV have special sockets and mounts on the front panel. The driver can use them on the go without leaving his seat, and at stops they can easily be carried ashore.
A tourist gas stove mounted on the right side of the cabin is also easily removable from its nest.
A special fuel tank on Ruslan is not provided. We believe that stationary tanks are not needed at all in our conditions, since there are no gas stations on the water and fuel must still be carried in cans. Therefore, the motors are powered directly from canisters connected by simple tees into two groups of two canisters in each. This system has been tested in long-term operation and has proven to be very convenient. Transparent-wall polyethylene canisters make it easy to control fuel consumption.
The motor control system consists of the simplest gas sectors with single-wire wiring and a return spring on the carburetor throttles. The reverse control is carried out according to a two-cable scheme of a well-known type and is easily dismantled. The motors are interconnected by a tubular rod, adjustable in length using threaded tips. The antenna device is a folding mast, on the lower part of which a SR connector is mounted, and on the top there is a navigation light and three telescopic antennas, two of which serve the TV, and one - the receiver. The television antenna is made easily removable so that it can be used ashore with a TV.
In the navigation of 1974, we took with us an additional set of two telephones (children's toy). It turned out to be useful for connecting the boat moored to the pier with the base camp located on the shore. It is also very convenient to have the VHF band in the radio, on which freight and passenger motor ships communicate with each other; This will avoid many surprises and troubles, especially when swimming at night and in bad weather conditions.

Despite the fact that the water area of \u200b\u200bthe yacht club was completely occupied, from the point of view of the pavilion exposition, it seemed that the number of participants this year decreased. However, as IFA Director General Sergey Levit commented on the situation: “This impression could have arisen due to the fact that many companies did not consider it appropriate to pull large boats into the pavilion this year. It is very expensive and will certainly affect the price. ”
However, some companies still decided to exhibit their boats in the pavilion. Among them: Faserind Boats, Airgroups, Siline Sales Russia, Alfa Yachts, Restmar, Bavaria Yachts, Admiral Market Marin, Yaroslavsky Kater LLC, Seagal Marine, Trade Marine, Royale Marine.
Special offers for buyers were provided by the company. According to the website, the company’s representative in Moscow Andrei Fadeev said: “Nimbus Boats shipyard finished accepting orders for the next year 15 days ago. However, she made an exception for the period of this exhibition. Here you can still book a yacht. ”
Special autumn discounts on Beneteau powerboats were provided by the company - the official Beneteau powerboat dealer in Russia. In addition to catalogs with well-known models, Boatmarket presented the catalogs with the updated model range of the Antares line: Antares 6 and Antares 7, comfortable motor boats combining the advantages of a cruise boat and a sports and pleasure boat at the third Moscow International Exhibition “Salon of Yachts and Boats” .
As for the exposition on the water, in the water area of \u200b\u200bthe SHORE HOUSE yacht club the vessels of the companies were located: Premium Boats Service, Grand Marine, Saratov Shipyard LLC, RSV - Yachts, Universal Marine, Bavaria Yachts, Ship Art Projects, Petroset, Ultrasail, Autopik-M , Sport-Aqua, Unisail-T, KSMZ, Timmerman Yachts, Poseidon-M, OAO DMZ Kamov, Trade Marine, Flagship, Aquaecopark, World Yachting Group, Aquadrive and Aoyama Motors.
The company also represented the Kral 700 Classic at the exhibition. According to the representative of World Yachting Group, Konstantin Yudin: “Fiart Mare 42 is just perfect for relaxing on the water. In addition, the sound of the engine is so soft that you can give in to philosophical reflection while you are cruising. ”
An interesting proposal was made by the company that introduced the trawler of the American company Mainship - 40 Trawler. According to Alexander Ilyin, the captain of the vessel: “40 Trawler is a full-fledged house on the water. It has everything you need for a comfortable stay, even a summer kitchen in the fresh air. This ship is ideal for long voyages by river, sea or ocean. ”
I would like to say separately about the proposals made by domestic enterprises. The tourist yacht “Tourist”, designed and built by specialists, attracted a lot of attention of buyers. This yacht is ideal for relaxing with a large company. Spacious roomy cabins, allowing guests to feel cozy and comfortable throughout the trip, equipped with all the necessary galley, equipped with a lifting mechanism, a crinoline, a solarium on the sun deck for lovers of sunbathing. The large main deck is divided by the control cabin into a large aft and small bow, which allows you to conveniently place a company of vacationing passengers, without distracting the captain from the control of the vessel. In the aft part of the main deck, for the convenience of guests, there is a full deck galley, a bathroom, a descent to the crinoline and to the engine room, as well as an ascent to the sun deck. For all its merits, the Tourist yacht stands several orders of magnitude lower than its foreign counterparts.
The RIVERLIFE motor ship built by OAO DMZ Kamov aroused undoubted interest. Houseboat RIVERLIFE combines a comfortable country house, beach and yacht. Without leaving the cozy walls of the ship, vacationers can take a river trip, have a picnic on the second deck, go fishing in any place you like. RIVERLIFE is also attractive in that its draft is only 50 cm, so vacationers have the opportunity to moor to any coast. Another undoubted plus - when welding the hulls, aviation technologies are used, which makes the assembly more accurate and accurate. As for the RIVERLIFE price, it is more than moderate.
The “Queen of the Exhibition” was the “New Star” megayacht presented by the company. According to the president of the International Association of Yacht and Boat Dealers Andrei Andriyanov: “This is a ship of the highest class. I hope that thanks to Timmerman Yachts and our other manufacturers, we will gradually occupy a fairly serious niche at exhibitions abroad. ”
As for the past, its main tasks, as stated by IFA Director General Sergey Levit, were “consolidating the yacht and boat market in Russia and stimulating trade”.
