How to make a plywood boat yourself. Homemade boats for fishing from different materials

Do-it-yourself plywood boat, drawings and stages of its construction.

Let's look at the picture of the presented model in the context:

Breshtuk - wooden beam 114x60 (mm)
frame - plywood 16 (mm) thick
sternpost - plywood 16 (mm) thick
kilson - wooden beam 30x80 (mm)
bottom - plywood 6 (mm) thick
board - plywood thickness 6 (mm)
handle - chrome-plated tube with a diameter of 16 ... 20 (mm)
floor - planed board 20x100 (mm)
deck - plywood 6 (mm) thick

A little about the material used:

Structural plywood
two types of sizes: 6x1500x3000 (mm); 16x1525x1525 (mm)
longitudinal arrangement of fibers
quality grade "E"
polished on one side "Sh1" (6x1500x3000)
unpolished "NSh" (16x1525x1525)
moisture classification “FB” or “BS”

Overall dimensions of a plywood boat

Let's start with the manufacture of: breshtuk; five frames; sternpost; kilson

Install on the staple and fix the breshtuk; five frames; sternpost

We insert the kilson into the grooves, having previously lubricated the contact planes with glue, and let the structure dry.

Take the cardboard and bend it along the plane of the sides and draw the outline of the side.

Take the cardboard and bend it along the plane of the bottom and draw the contour of the bottom.

After making sure that the measurements of the contours are accurate, we transfer them to plywood and carefully cut them out. We should get four parts - two left and two right, and the right parts are a mirror image of the left.

Fastening start from the bottom.

Using brass or galvanized screws and epoxy glue, we fix the parts cut out of plywood to the frame of the structure. After the glue has hardened, we will align the contour grinder.

Attach the sides in the same way.

We fasten the joints of plywood parts as follows:
1. Drill along the joints, at the same distance, through holes with a diameter of 3 (mm).
2. Insert a nylon cord into the holes.
3. We tighten the parts together.

After the glue has hardened, we level the contour and the joint surfaces with a grinder.

From above, by analogy, we fix the deck. Align the joint surfaces.

We will glue all the joints with two layers of fiberglass and let it dry.

It won't hurt if you fiberglass the entire hull.

We will finish the body and paint it in an interesting color.
For structural rigidity, from the bottom of the seat, we will strengthen the wooden bars on both sides.
Let's lay the boards on the floor. Install metal handles on top of the deck.
Do-it-yourself plywood boat is made:

Probably every fishing enthusiast at least once thought about how to make a homemade boat. This is not an easy task, but it is still possible to make such a craft.

And it is not necessary to be an engineer, all that is required of you is a few hours of free time. And you will learn about how home-made plywood boats are made from our today's article.

Manufacturing difficulties

Is it really difficult to make such a design with a minimum set of tools? As practice shows, even with such equipment, a home-made inflatable boat (or plywood) is easily made in 3-4 hours. Due to the fact that it takes a minimum of time to complete all these works, you can even make a boat in the open air. Well, in the event of a change in the weather, you can always cover it with a tarpaulin or a piece of plastic wrap.

What are good

Firstly, plywood is a lightweight, durable and fairly warm material. It is almost impossible to kill such a boat, and it does not weigh too much. Secondly, unlike rubber counterparts, the space in a plywood boat is enough for several people (at the same time, inside, between the seats, you can fit all the necessary fishing tackle). In store options, free space is sorely lacking.

Thirdly, being in a wooden boat, you do not feel discomfort at all.

Preparation of materials

The main material from which homemade boats are made is plywood. There are no difficulties in finding it on the market. Plywood is perhaps the most affordable and cheap material for such work. Yes, and it is very convenient to work with her.

Getting down to business

First of all, I would like to note that any work related to self-manufacturing any means (be it a tractor or something else, it doesn’t matter), must be carried out clearly according to a given scheme. In this case, you should have drawings of homemade boats in your hands. In some cases, drawings can be replaced with a sketch drawing.

So, how it is done To assemble the case, you will need to prepare dry boards 2.5 centimeters thick and a 6-mm plywood sheet. The width of the boards for the stern and sides should be 30.5 centimeters. This is the most optimal dimensions for a fishing boat. All other elements that are inside the structure (seats and struts) are made from boards 2.5 centimeters wide. At the same time, the length of these parts is 86.4 centimeters. It must be borne in mind that the dimensions of all these elements must be exactly maintained, since they are all attached to the boat hull only with self-tapping screws.

The manufacture of all parts and elements of this design does not cause any difficulties and difficulties. This is due to their simple geometric shape.

In the course of work, pay special attention to fitting the mating surfaces and frilling the boat. All joining edges must be carefully fitted and have minimal gaps along the entire length. As fasteners, either tin-plated or galvanized self-tapping screws are used. As for the dimensions of these fasteners, depending on the place of application, they can be as follows:

The bottom of the boat is made of plywood sheet 6 mm thick. But, since this part of the floating facility will be constantly exposed to water, for the watertightness of the boat, additionally treat the joints of the hull and the bottom with glue of the VIAM-B / 3 type and fix it with screws around the entire perimeter. If there is no such tool ("VIAM-B / 3"), oil paint is quite suitable as an alternative. Although it does not have good adhesive properties and characteristics, it gives a durable and waterproof coating. It should be noted that the distance between the screws should be about 4 centimeters. External seams should be carefully glued with a cloth or percale using AK-20. In order not to fail the bottom of the boat, a rack grate is installed between the struts (the cross section of the rails is 5x2 centimeters).

The resulting liquid should be diluted with clean drying oil. In this case, the calculation is made so that the boat can be painted another 2-3 times. In terms of its properties, liquid paint is better, it spreads more easily, and therefore gives a more durable and even coating. When applying this product to the boat, wide soft flute brushes are used.

Some enthusiasts use nitro paints based on their high quality finish. However, we do not recommend using them for such boats, as they do not provide the necessary durability to the wood (accordingly, the structure becomes less durable and unusable every year).

Important Points

If home-made motor boats are made, then a drawing of special mounts for an electric or gasoline engine is additionally made. However, a simpler and cheaper option would be to use conventional oars. They are often made from a 35mm birch plank. At the same time, a spike with a handle is installed at the end of the spindle, and brass linings are applied to the edge of the blade. Next, the paddle is primed and painted.

And finally, some statistics. As practice shows, average term service life of plywood boats is about 15-20 years. Neither plastic nor even their rubber competitors can boast of such survivability.

If you are an avid fisherman, or just have no idea warm time years without rest on the water, then a small river boat will be a very appropriate purchase for you. However, finished products of this type cost a lot, but a home-made plywood boat is quite simple - so it makes sense to spend some time mastering the technique, and then assemble a small skiff, kayak or punt with minimal cost and effort.

In our article, we will describe the manufacturing process of such a structure, starting with the selection of material and ending with the finishing technology.

What do we need

Set of tools

Getting started, we should take care of having all the necessary tools.

In principle, the set will require a simple:

• saw on a tree (disc or reciprocating);
• electric jigsaw with a set of blades;
• grinder with nozzles for processing plywood;
• drill and drills of different diameters;
• screwdriver;
• clamps for fixing the parts to be glued;

• hand tools - hammers, pliers, chisels, etc.
• measuring tool - tape measure and level.

Work is best done in a free garage or workshop. In principle, parts can also be assembled on the floor, but it will be much more convenient to work if we construct special goats from timber and thick boards, on which all the elements of our future boat will be placed.

Selection of materials

Plywood boat projects, abundantly presented on the Internet, involve the use of the most different materials. We will look at one of the most simple modifications, since it is better for beginners to work out techniques on simple samples.

To build a ship we will need:

Structural element	Material Features
Boards and bottom	We use plywood sheets as the main material for the manufacture of the bottom and sides. Plywood for a boat must meet a number of requirements: thickness - from 5 to 10 mm, depending on the design of the side. Sometimes elements of a thicker (up to 15 mm) material are installed inside to reinforce; maximum moisture resistance. Boards are best made from phenol-formaldehyde or bakelite plywood. Panels based on a carbamide binder are also suitable, but in this case additional moisture protection treatment will be required, for example, pasting with fiberglass; grinding is one-sided. For reasons of safety and reliability, the ground layer is placed on the outside.
Inner frame	Support structures - frames, keel, struts, as well as seats and transoms are made of more durable materials: plywood 20-25 mm thick; edged board of the same size.
Connecting elements	Very often, only glue is used to connect parts into a single structure. At the same time, some methods involve stitching plywood sheets using thin steel wire, nylon cord, thick fishing line, etc. As an additional reinforcement of the seams, strips of fiberglass impregnated with epoxy resins are used.
Exterior finish	No matter how high-quality plywood is, it will swell with prolonged contact with water. That is why both outside and inside everything wooden details treated with special formulations. These include: stains; impregnations with antiseptic and moisture protective components; varnishes and paints.

Drawings of the boat and transferring them to the material

Before proceeding with the purchase of materials, we will need drawings of plywood boats. Building a punt or tourist kayak scheme on your own is only worth it if you have sufficient experience and you clearly understand what size boat you need and what design it must have. It's better for a beginner to use finished project Luckily, it's easy to find it online.

So, before making a boat out of plywood, we proceed as follows:

1. Based on the drawings, we make templates of the desired shape and size from wrapping paper or old wallpaper.
2. A plywood boat pattern is applied to wood panel and circled around.
3. Similarly, templates are used to mark the boards and beams from which the inner frame will be made.

When transferring dimensions to workpieces, we are likely to encounter difficulties. This is related to the fact that standard size plywood sheet (maximum 3000 mm in length) is often less than the planned dimensions of the boat. In this case, we need to master the technique of gluing plywood:

We adjust the ends of the two parts to each other.

1. Gently weave the edges to a length exceeding the thickness of the sheet by about 7-8 times.
2. The resulting bevels are lubricated with carpentry or polymer glue and securely clamped with clamps.
3. After complete polymerization of the glue, we get a fairly long sheet with a strong “whisker” connection.

Method of work

Boat hull assembly

In this section, we will tell you how to make a plywood boat yourself using blanks, drawings and templates prepared as described above.

The instruction assumes the performance of work according to the following scheme:

1. First, using a jigsaw or reciprocating saw, we cut out all the details from plywood. When sawing out, we try to act very carefully, strictly observing the dimensions - even a discrepancy of 1 mm can lead to the fact that large gaps form when assembling the sides, and we will have to perform a laborious adjustment.

1. We cut the frames from a thicker board, or glue them from several layers of plywood. When gluing, the mass of the part will naturally increase, but this will not affect the buoyancy of the structure much.
2. Rowing boats made of plywood are made with a standard stern board (transom), but for a motorboat you need to install a more durable part. Quite often, the stern transom is made multi-layered: plywood 8-10 mm + fiberglass + oak board about 15 mm.

Advice!
Multilayer parts are sometimes additionally tightened with self-tapping screws.
In this case, the length of the fastener is selected in such a way that the caps are deepened by about 0.5 mm, and the sharp edges do not protrude.

1. We install the glued or solid transom on the goats or workbench and apply to it. After that, we fix the parts with clamps and bring the plywood sheets on the bow, forming the outline of the boat.

Many did not even know that you can swim in a homemade plywood boat. The article will provide a step-by-step description of all the processes for its manufacture, drawings and lists of everything needed from materials to tools. The instructions are also accompanied by illustrations of work and a video on the manufacture of the structure by the master.

Preparation of material and tools

• Plywood;
• polyurethane adhesive;
• Nails;
• Latex based paint;
• silicone sealant;
• Construction syringe (it will be needed to seal the seams of the structure);
• Sandpaper;
• Jigsaw;
• Screwdriver;
• Roulette;
• Brush;
• clamp;
• Drill;
• Paracord (staples).

One of the sheets of purchased plywood must be divided into 3 parts for the bottom of the structure: 46x61 cm, 61x168 cm and 31x61 cm. The sides of the boat will be two pieces measuring 31 by 244 cm. To create props, we take 3 pieces with parameters 25x50x2400 mm. A cut of 25x76x2400 mm is required for the stern and bow of the boat. The hull of a home-made boat made of plywood for fishing is made from pieces with parameters of 25x50x2400 mm.

Note! Subsequently, the pieces on the body will be connected with paracord.

Creating a project with drawings

There are many projects for homemade plywood boats, ranging from a simple punt that is used for fishing to a complex tourist kayak. There are both prefabricated and folding structures. To begin with, let's dwell on the simplest drawing of the vessel, which is presented below.

If a home-made boat made of plywood according to the drawings that was found does not suit you, then you can design your own version, but such an event will require more accurate calculations regarding the carrying capacity of the structure. Otherwise, with the wrong parameters, you can make a huge souvenir that is not able to keep you on the water.

So, choosing or creating your own project to build plywood boat, we transfer our parameters to paper, creating a design drawing. Using these paper templates, we draw the outlines of the main elements of the boat on plywood sheets, which will serve as an orientation for cutting sheets and frames for sheathing.

Note! In most cases, the size of the factory plywood does not allow you to cut out a single element of the side of the boat. Therefore, it will be necessary to carry out the procedure for splicing the sheets.

The splicing of the pieces begins with the cutting of the ends of the sheet at an acute angle. As a result, the hewn part should have a length equal to the thickness of the sheet, increased by 7-10 times. The connected parts with bevelled ends are perfectly shown in the diagram below.

Pieces that are ideally beveled under each other must be smeared with glue along the bevel and firmly clamped with clamps using the “whisker” method. While our pieces are sticking together, you can prepare the bars for the frame of the boat. It will be more convenient to work on goats specially created with your own hands from 5x5 cm bars.

You can also make a homemade folding plywood boat, the drawing of which is presented below.

Assembling the hull of a simple boat

First of all, we will make frames (although you can make them after assembling the plywood frame). Having drawn and sawn the necessary bars, we fasten them with self-tapping screws and epoxy glue.

Frames

Note! At the stage of sawing out the elements, deviations from the drawing parameters should not be more than 1 mm, otherwise the sides may not be sewn together.

The assembly of a homemade plywood boat is shown in detail in the video, which is added to the article.

First of all, we install a transom on our goats, to which we attach the bottom and sides, leading them a little to the middle, connecting them with brackets on the nose. With a small thickness of the plywood sheet, the sheathing can be connected with suture material or an adhesive mixture. When assembling, make sure that all elements match in size.

Gluing the frames and the side is necessary to provide greater thickness, and, accordingly, increase the strength of the structure. Also, in order to increase the reliability of the connections, it is recommended to additionally fasten the transoms and frames with tin-plated or galvanized self-tapping screws 18 or 25 mm long and 3 mm in diameter. Self-tapping screws for the stern and sides are taken a little more: 60 by 4-5 mm.

Adviсe! If a gap is obtained when connecting the elements, it is necessary to disassemble everything and cut it to right size frames. And for a home-made boat made of plywood for a motor, you need to remember to glue the transom with fiberglass, as well as fasten wooden planks made from solid wood.

Special overlays can also be cut on the transom to strengthen the structure as a whole. When all the elements are assembled and converged with each other, then you can start gluing the structure. To make the seams come out especially neat, you can use masking tape that is glued on both sides of each seam.

We produce sizing with a mixture of Aerosil and epoxy resin(1:1), we carefully work with fiberglass so that no bubbles result. The gluing seams should come out even, and the wood structure should still be visible through the fiberglass layers.

Then we turn the almost finished boat upside down and remove the staples if they fasten the elements, and also round the seam joints. Having obtained the desired streamlining, you can also glue the seams from the outside.

In addition to gluing, the structure can be reinforced with 3 layers of glass tape or completely sheathed with fiberglass. You can also add benches to the design, for which we make planks, as well as cut out the stem and install the bow eyebolt. The outer stringers and keel will need high quality materials to keep knots out. The polished elements will strengthen the structure, and also serve as protection for the skin during mooring.

The basics of making a folding structure

You can also make a homemade collapsible plywood boat according to the above drawing. Such a boat will consist of several independent sections, which in turn represent a part of the structure, the length of which is equal to the distance between the frames, which are located nearby. In other words, the boat is "cut" into pieces.

The sections are assembled by means of bolts, and for a snug fit of the parts to each other, a rubber seal is laid between the sections. When assembled, all the rest are placed in the largest middle section with a nesting doll. And then all the elements can be packed in a cloth case and easily transported by car or other means of transport.

For the manufacture of collapsible design will need the following materials:

• Plywood: 2.5 sheets for sheathing - construction 4x1500x1500 mm, part 1 sheet for the stem and frames - 10x900x1300;
• Boards for removable seats.

Plywood must be purchased in grade 1 so that there are no knots, but there is a hitch! Boards 6 m long - we take one coniferous tree 2 cm thick, and the other from any tree 4 cm thick. We also need meter-long beech boards to finish the side of our boat.

First of all, we also create a design drawing, after which we do paper templates for transom, frames and stem. In the frames cut with a hacksaw according to the templates, it is necessary to drill the corresponding holes for the bolts, after which we connect the sheets. Frames need to be filed and glued on the outside rubber seal 1 mm thick.

Also, in the frames, you need to make holes for rivets, which will be located in pairs for every 1-5 cm, screwing in 1 cm from the edge. They can be built independently from wire with a diameter of 1.5 to 3 mm from aluminum wire. With the help of a conductor, sections are assembled.

When all the elements are made and assembled, the entire structure must be impregnated with drying oil, it is recommended even in two layers. But always on top of dry plywood. When the drying oil dries up, the inside must be opened with varnish, and the outside with oil paint.

The development and appearance of such an unusual project is due to the widespread interest of sailing enthusiasts in maritime antiquity. A small and shallow-draft (draft 1.5 m), but quite seaworthy cruising yacht, designed for long-distance voyages of a crew of 8-9 people, some features are given that are characteristic of sailboats of the 18th - early 19th centuries - the heyday of the sailing fleet. However, the project provides for the use modern materials and hull design, as well as technological methods used today ...

The ship's spar was designed taking into account the main features of shipbuilding since the sailing fleet: the "classic" proportions and principles of armament have been preserved. In the old days, the masts of small vessels were most often made in one piece, or they were recruited from well-fitted parts - pieces fastened on the outside with vulpings (binding with a strong cable) through 800-1000 mm ...

For some time now, operations with the 48-kilogram Whirlwind have also become difficult for me - carrying it from a place of storage to a boat, hanging it on a transom, removing it from a boat, etc. A dream appeared of a leisurely displacement boat with an economical stationary engine, with a cabin , which would protect from rain and wind. And so the boat presented in the photo and sketch appeared, equipped with a four-stroke carburetor engine "UD-25" with air cooling ...
