How to make a boat from plywood with your own hands: dimensions and drawings. DIY plywood boat drawing: patterns of motor boats for DIY construction, manufacturing, video review Do-it-yourself folding plywood boat

Classic fishing on the river bank is, without a doubt, very convenient and in some ways even romantic. However, what to do if all the treasured fish are found far from the shore or in a place that cannot be reached except by water?

A boat is the best solution to this problem. But their cost in stores forces fishermen and tourists to sometimes show initiative and ingenuity, creating watercraft from literally nothing. What materials can you use to make a boat with your own hands?

Boat made of plastic bottles

An unusual but effective material for creating a boat can be commonplace plastic bottles. Since most The common volume of such containers is 2 liters, the most difficult stage in the design will be the collection of material.

In order to create a “bottle” boat, you will need the following materials:

Bottles;
Waterproof tape and glue;
Knife or scissors;
Wire;
Plywood and crossbars made of wood or metal.

First of all, you need to thoroughly clean the bottles of stickers and labels. However, the most important thing to do at this stage is give plastic containers density and rigidity. The laws of physics will help with this. The bottles are placed in the refrigerator, where the lids are tightly screwed on, and then moved into a warm place. Thus, the air inside the bottles heats up and gives them an elastic shape. For greater reliability, it is advisable to secure the covers with waterproof glue.

Installation of a boat from plastic bottles

Original logs are formed from pre-prepared bottles.

First step- connecting two bottles with their bottoms. To secure it, pull on a plastic ring cut from the middle of an empty bottle. This entire structure is coated with glue and tightly wrapped with tape in several layers.

The top parts of the next two bottles are cut off, after which the headless plastic is placed on the edges of the workpiece, again using glue and tape. This way, a reliable and sealed fragment of the future boat is obtained.

The further process consists of repeating the above steps and ends with the production of a log of the optimal size.

One float consists of eight logs, which are connected with strong wire, polyethylene and tape. Depending on preferences, the number of logs can vary up or down. The most important thing is to maintain balance and make the boat a reliable means of transportation.

The floats are mounted using crossbars made of wood or metal. The bottom of the boat can again be made of various materials. It can be plywood, plastic or metal sheet.

The final touch in making a boat can be covered with waterproof fabric or finishing with strong plywood followed by painting. This will improve the boat’s reliability and aesthetics.

Plywood boat

In addition to plywood as the main material, to create such a boat you will need:

Jigsaw;
Screwdriver;
Saw;
Hammer;
Grinding device;
Clamps and brushes;
Wood;

Glue, resins, varnishes, drying oils, etc.

Installation of a plywood boat

The most acceptable option is large-sized plywood without defects in the form of delamination and cracks.

With the help of drawings, extremely careful marking of the material is carried out. If you make the slightest mistakes and discrepancies, making a boat without cracks will become impossible. To outline the plywood, you can use special patterns.

Next, each fragment is cut out with a saw and jigsaw. Particular attention is paid to the joining angles at the ends. The tailgate and frames will require installation of plywood in several layers to increase strength. If the design of the boat assumes the presence of a motor, then the tailgate supplemented with hardwood and glued with fiberglass.

Frames and transoms are fixed with tinned or galvanized screws. The bottom and sides are attached to the transoms using special glue and other materials for seams. It is advisable to strengthen the bottom of the boat with slatted flooring.

The seams are sealed with a special sealant, which contains epoxy resin and Aerosil in a 1:1 ratio. The fillets are stiffening ribs and are laid in the corners. All internal joints are treated with sealant, after which fiberglass is applied to them.

After drying the entire structure, frames, flooring on the bottom, seats and other planned elements are installed.

Before painting, all surfaces are degreased and sanded, then carefully treated with wood impregnation. If after all these actions the surface remains uneven and has cracks, a special putty comes to the rescue, and after drying, a primer.

Usually used for painting marine enamel, hard brush or spray gun.

Folding boat made of duralumin

To create a folding boat you will need:

Duralumin sheets;
Rubberized fabric;
Rivets and overlays;
Wood;
Metal scissors;
Primer and paint.

Installation of a folding boat made of dualuminium

Duralumin is the most advantageous material for creating a folding boat. It is light and very durable, and to create a watercraft you need only six elements: two for the bottom and four for the sides.

There are only three transverse struts in such a boat: one of them is the seat, the other two are struts made of wood with aluminum tubes at the ends. They are inserted into holes on the inner sides of the sides, which ensures the rigidity and reliability of the structure.

Before you start assembling the boat according to the drawings, it is recommended to recreate its prototype from cardboard. This will make it easier to eliminate all mistakes, and besides, such cardboard parts will also serve as patterns for duralumin.

All six parts of the folding boat are cut out with tin snips, then trimmed and hemmed. Holes for rivets are drilled in the joints every 2 centimeters. After that, the fragments of the boat are fastened with rivets, which are sealed with paint. Installation of duralumin can also be carried out using rubberized elastic fabric.

The gunwale and seats are made from any available wood and mounted with galvanized nails. Finally, the finished boat is primed and painted.

The development and emergence of such an unusual project is due to the widespread interest of sailing enthusiasts in maritime antiquities. A small and shallow-draft (draft 1.5 m), but quite seaworthy cruising yacht, designed for long-distance voyages with a crew of 8-9 people, is given some features characteristic of sailing ships of the 18th - early 19th centuries - the heyday of the sailing fleet. At the same time, the project provides for the use of modern materials and body design, as well as technological techniques used today...

The vessel's mast was designed taking into account the main features of shipbuilding from the times of the sailing fleet: the “classical” proportions and principles of armament were preserved. In the old days, masts of small ships were most often made in one piece or assembled from well-fitted parts - pieces held together from the outside with vulings (tied with a strong cable) every 800-1000 mm...

For some time now, operations with the 48-kilogram “Whirlwind” have become difficult for me - carrying it from the storage place to the boat, attaching it to the transom, removing it from the boat, etc. A dream appeared about a leisurely displacement boat with an economical inboard engine, with a cabin , which would protect from rain and wind. This is how the boat shown in the photo and sketch appeared, equipped with a four-stroke air-cooled UD-25 carburetor engine...

Captain Vrungel believed that whatever you name the ship, it will sail. We will not argue with the old, proven sea wolf, but we will still put forward our opinion - the more carefully and carefully you prepare the drawings of a plywood boat with your own hands, so it will serve you for many years and in any weather. It is the drawings of the vessel that will determine all your future decisions.

They are the ones who will introduce you to this world of shipbuilding, where Anglo-Dutch terminology rules. And understanding the terminology of boat design elements, and therefore successfully reading the proposed drawing, is fundamentally important.

According to the old axiom, start from the stove

Drawings of a homemade plywood boat must include strict instructions on how to attach all elements - this is a key issue for the entire design

Indeed, terminology, when throwing yourself into such a bottomless field as boat building, is of great and crucial importance. We bring to your attention its fundamentals regarding the design of boats, which appear everywhere in the drawings.

Terminology

Therefore, understand these terms very carefully; they literally permeate any worthwhile drawing of a boat made of any material.

In the side view we note the following structural elements of the boat, and it is impossible to say which of them is most important, which is less important, all elements are required to be used:

A – frame. You can choose the option of an ordinary punt, without frames, but when it comes to such an aspiration thrown on the Internet as “do-it-yourself plywood boat drawings”, the reliability and strength of the structure comes to the fore, which means frames are required;
Spacing is the distance between two frames. The most important characteristic of the design of any boat;
B - sternpost;
C - stem;
D – beam
E – keelson. A very desirable design element, which, however, is often discarded for boats;
F – fender. You cannot do without this element if you are going to add a superstructure to the boat. For open models, the fender is not used.
I – breshtuk. We strongly advise you not to neglect this element; the strength of the entire structure greatly depends on it.
J – book. The bracket is also extremely important in ensuring the strength of the boat.
K – stringer. It is also an indispensable element if you approach construction with the utmost care.

The top view introduces a few more important terms:

A – beam;
B – half beam. Goes into a full beam if you do not build a superstructure on the boat;
C – karengs;
D – midsection.

The view from the forecastle introduces terms that will be fundamentally important at a more advanced stage of construction, when it becomes necessary to strengthen the hull of the boat and install a sail and keel, also improving sailing performance:

A – tongue and groove belts;
B – keel. By ensuring the keel weight is 50 percent of the weight of the entire boat, you significantly increase its stability. After all, you never know how the rolling will affect you or future passengers, and a solid supply of sucking sweets and even ginger can do little to prolong the pleasure of being on the water, except to quickly get to the shore;
C – steps. Mandatory if you are putting up a mast;
D – tongue and groove;
E – partners. This is the name of the hole in the superstructure for the passage of the mast. Of course, if you don’t have an add-on, then you can forget about partners for now;
F – velhout. A very important sheet pile belt at the level of the waterline, water;
H – shearstrek. The topmost tongue and groove belt.
G – water level;
I – waterweiss. This element is already an element of the add-in.

Plywood

The most common material for making boats today is, of course, carbon fiber. But this material is the domain of industry. When it comes to independent creativity, such “folk” material as plywood comes to the fore..

Plywood, or in other words, wood-laminated board, is a building material created by gluing together specially produced veneer. Usually the number of veneer layers is odd and, in any case, more than 3. To increase the strength of plywood, each subsequent layer of veneer with its wood fibers is perpendicular to the fibers of the previous layer. Frames are the basis of any floating craft. Drawings of plywood boats that claim to be something more than the title of punt must have a separate option - the location of the frames

Characteristics of plywood

When choosing plywood for boat construction, it is very important to choose the right type.

Based on the arrangement of wood fibers on the outer layers, plywood is distinguished:

Longitudinal, when the fibers are directed along the long side, and,
Transverse - along the short one.

To build a boat, it is better to choose a longitudinal one.
Of course, such an isometric drawing is also possible, but this is the simplest option for the “free plywood boat drawings” section - there are no frames, and the work is in many ways similar to assembling a children's construction set, except that the parts are tens of times larger

By purpose, plywood is divided into:

construction,
industrial,
packaging,
furniture, and
structural – this is exactly what we choose for our purposes.

There is a classification of plywood in relation to the effects of moisture, which is fundamentally important for a boat:

FBA is like this, but you shouldn’t choose it, it doesn’t meet the strict requirements for moisture resistance;
FC – this is the designation for plywood that is sufficiently resistant to moisture;
FSF - and so, with increased moisture resistance;
FB – impregnated with bakelite varnish, such plywood is considered the most resistant and can be used even in aggressive environments, which is important in our case, and under water;
BS - this one is simply impregnated with bakelite glue. Consider that if you have such plywood at your disposal, then the success of the whole business is 50% guaranteed. This type of plywood has been specifically used in aircraft and shipbuilding for quite a long time. It happily combines all the qualities necessary for a boat craftsman - excellent flexibility, highest strength, complete waterproofness, and also resistance to rotting and deterioration;
BV - but don’t be fooled by this one, it is in many ways similar to BS, but does not have moisture resistance.

Helpful advice!
When choosing plywood for boat construction, we recommend paying attention to laminated plywood.
At the very least, it will be just great if you use one as tongue and groove belts or on the outside of the case if it is single-layer.
This will greatly improve the driving performance of your creation, because water is a medium in which frictional force plays a significant role.
On the other hand, you should not use laminated plywood inside the boat.
Its slippery surface itself, and even wetted with water, can cause a lot of trouble.

Principal characteristics

When it comes to using plywood to build a boat, it is important to choose plywood based on its quality, determined by the number of knots per square meter of the outer layer.

There are 5 quality levels here:

E – so-called elite quality, when there are no knots at all. It is probably unnecessary to say that it is always necessary to strive to choose just such plywood;
Well, then, a simple classification of quality - I, II, III and IV. In the latter case, the number of knots is not controlled.
I – maximum length of knots and warping does not exceed 20 mm;
II - cracks no more than 200 mm, wood inserts are permissible, and glue leakage is permissible only on an area of 2% of the total sheet area;
III – no more than 10 pieces of knots with a diameter of no more than 6 mm. There is even a limit on the total number of deficiencies - no more than 9;
IV – this is the worst quality with even fallen knots and edge defects of up to 5 mm.

Operating conditions requirements

Most likely, for building a boat you will choose as the most common one. There is also birch plywood, but its use is limited by too high a price.

Another thing is very important here - the quality of processing of the outer surface of the plywood sheet.

Based on this indicator, plywood is distinguished:

NS – unpolished;
Ш1 – polished on one side;
Ш2 - polished on both sides.

Here it is fundamental and mandatory to use the sanded side of the plywood on the outside of the body. It is advisable, for safety reasons, not to use the polished side on the inside.

Dimensions

A natural characteristic of any sheet of plywood is its size.

The industry, according to standards, produces sheets of the following four sizes:

1525 x 1525 mm;
1220 x 2440 mm;
1500 x 3000 mm;
1525 x 3050 mm.

Your choice will largely depend on the size of the boat.

Helpful advice!
All the given characteristics of plywood must be indicated in the specification of the boat drawings.
Under no circumstances agree to purchase the proposed boat drawings if they are not accompanied by a detailed explanatory note describing all the nuances of manufacturing, and most importantly, the choice of type of plywood.
The drawings must indicate the degree of processing of the external sides of the housing.
In this regard, the grinding machine will be one of the most in demand in your work.

conclusions

Building a boat is a fascinating creative process for people who still like to live, who are not afraid to experiment and have a design streak. (see also) But, on the other hand, you shouldn’t reinvent the wheel; be sure to familiarize yourself with all the photo materials, study the terminology and various design solutions.

Prepare yourself for possible reworking of unsuccessful decisions. Know how to “talk to yourself” and communicate with experienced masters. Only in this case is the success of the entire enterprise called “building a plywood boat with your own hands” possible.

In the video presented in this article you will find additional information on this topic.

Good day to all!
Today the author of this work invites us to look at the process of making a homemade plywood boat; he was inspired to do this by an old dream. First of all, he went to one of the factories where similar boats are produced, it is located in the city of Cherepovets, where he emphasized several points for himself that would later be useful in production, and bought the necessary material there.

To make a boat we will need:

Tool:

Pencil;
- ruler;
- electric screwdriver;
- Sander;
- electric planer;
- clamps;
- pliers.
- square ruler.

Materials:

Plywood;
- copper wire
- fiberglass;
- epoxy adhesive;
- self-tapping screws.

Since the plywood sheets were smaller than the planned dimensions of the boat, the author had to glue them together, after going through all the possible options, this type of gluing was chosen “on the fly”

And so, we take the sheets and start marking.

We smooth the ends of the plywood at an angle, for this we use a plane, and then we go through it with a sanding machine

It should look like this.

Next, the sheets are applied to each other and glued together using wood glue, then we place them under the press, placing a pressure bar along the entire length of the seam.

After the sheets have finally glued together, you can remove them from under the press, remove the clamping strips, the joint should be smooth and very strong, so we got the blanks of the length we needed.

We mark a center line on a sheet of plywood; all the main dimensions will go from it in the future.

Draw the bottom of the boat, as shown in the photo

Next, using an electric jigsaw, we cut out the bottom according to the markings; we use a specialized blade designed for plywood; it is best to cut at high speeds.

Then we mark one side for the boat, cut it out, and use it as a template for making the second one.

Next, we make markings and cut out the transom.

We join the cut parts together and chamfer them at the joints using a grinding machine. Next, we make holes on the sides and bottom of the boat with a thin drill, and begin to sew together the elements of the boat using prepared pieces of copper wire, which we insert into the holes made, and then twist with pliers.

Sew from stern to bow.

In this process you will need an assistant, since it will be difficult to do it alone.

Example of seams.

The final result, when the last part is fixed, we get a body like this.

We do a fitting.

Next, we check the geometry of the resulting shape; if necessary, we additionally tighten the brackets, and then use a chisel to fit them, doing this from the inside of the sides. After the operations were completed, we cut out and installed temporary spacers; they were secured in place of the future frames.

In order to form a more even seam, it was decided to use masking tape.

Next, the author drew a template for the frames and began assembly.

These are the frames we got, everything is fastened with self-tapping screws and epoxy glue.

Let's start gluing the internal seams, for this we use strips of fiberglass and epoxy resin, glue it in three layers, try to saturate the fiberglass well, make sure that there are no bubbles.
