Children's crafts from natural material. Boat plastic for fishing. Is it possible to make a plastic boat with your own hands
The article provides a detailed description of the manufacturing process of a plastic boat, indicating the stages of work and the materials used.
In the manufacture of the boat hull, the reinforcing filler is impregnated polymer composition by contact molding. This approach is widely used for the manufacture of dimensional products of any relief, based on polymer composite materials. This method is especially popular due to its low cost and simplicity. technological process. Subject to the exact observance of the technological stages and the accuracy of the work performed, even a not very experienced craftsman can make a boat out of fiberglass.
Speaking about raw materials, it is worth noting that as a reinforcing filler for a boat frame, they use:
- roving glass fabrics of the TR-07, TR-03, TR-056 brands, which are needed as the basis of the hull and rapid thickening of the walls;
- structural glass fabrics of grades T-11 and T-13. They are used for local reinforcement of individual sections.
Polyester resin TM Ashland is indispensable for gluing reinforcing material. Gelcoat of the same trademark used to create a decorative and protective surface of the boat hull. Moisture resistant plywood is used to reinforce the frame.
If we omit the work on creating a drawing and a matrix, and dwell directly on the production process, then we can conditionally distinguish several fundamental stages in the manufacture of fiberglass boats.
- Matrix preparation. At this stage, the form is cleaned of contaminants and degreased. After that, an anti-adhesive composition is applied to its surface. This layer will not allow the resin to stick to the surface of the form, that is, it will conditionally serve as a separator.
- Open fiberglass. For cutting fiberglass, which is a reinforcing filler, you can use special templates, which will greatly simplify the work.
- Application of gelcoat. This decorative coating will allow not only to create a beautiful surface of the future vessel, but also provide long-term protection of the hull from scratches, abrasions and fading in the sun. Applying a gelcoat is a very responsible matter, due to flaws at this stage, it may suffer appearance products. You can apply the composition with a soft varnishing brush, or using a special spray gun. The main thing is that the gelcoat is applied evenly, without streaks and air bubbles. Then you need to let the gel dry completely. Fingers do not stick to a dry surface.
- Body molding. The cut parts of the reinforcing filler are laid on a layer of gelcoat. A bonding polymer resin is evenly applied to the fiberglass with a roller. From above, the surface is covered with another layer of fiberglass. And so the number of layers that is necessary is successively applied. In this case, carefully remove air bubbles from under the fiberglass and evenly distribute the binder using a roller. This is the main condition for creating a strong and reliable case. Indeed, in places where unimpregnated cavities remain, voids are formed that will weaken the entire structure.
- Creation of a power frame. To reinforce the ship's hull, three wooden bars are laid along the mold. Each of which is applied two layers of fiberglass. Then, every 30 cm, frames are mounted on them, also treated with fiberglass in two layers.
- Floor installation. Sheets of moisture-resistant plywood are attached to the laid frames with the help of self-tapping screws. The plywood floor is sequentially covered with two layers of reinforcing fabric, not forgetting to fasten them with polymer resin. This procedure creates an airtight double bottom of the vessel, making it virtually unsinkable even when capsized. After that, leave the product until the binder resin completely hardens.
- Boat assembly. On final stage the boat is removed from the mold. Then you need to trim the allowances and carefully sand the surface of the boat. After that, a roof and a beam are mounted on the hull to protect the sides.
Obviously, with the necessary knowledge and a simple tool, you can quite simply make a reliable and beautiful boat.
Building boats from plywood with a fiberglass exterior is quick and cheap. I made several of these boats, but later abandoned this technology. Despite the protective layer of plastic, plywood quickly gains moisture, the weight of the hull increases and the speed characteristics of the planing boat decrease. And of course - the strength of plywood is much lower than the strength of monolithic fiberglass. In case of poor ventilation and in conditions high humidity plywood is quickly destroyed by microorganisms and delaminates.
Fiberglass does not have these disadvantages, but the construction of boats from it is very laborious. You must first make a blockhead or matrix, mold on them plastic case, then paste the set into it. Making a blockhead or a matrix is justified when building at least 4-5 boats, but it is quite difficult to find so many fans to build the same hulls.
I applied a different technology. The design of the hull kit is practically the same as a boat with plywood sheathing. First, frames cut out of plywood 12-16 mm thick are installed on the slipway (all their joints are glued “on the mustache” epoxy glue); then the keel crashes into them, and then the stringer. I recommend making bottom stringers from oak, side stringers - glued from several pine or spruce slats. From the edges of the set adjacent to outer skin, removed .
The entire outer surface of the body is divided into sections within which it can be sheathed with one flat sheet fiberglass. A cardboard template is removed from each section or thick paper. Plastic in the form of sheets is glued on the table, and hot irons are used to accelerate polymerization. All work on the manufacture of plastic sheets must be carried out outdoors, since the heated resin abundantly releases volatile components that are toxic. A tracing paper is spread on the table, which serves as a separating layer, 3-5 layers of fiberglass are applied to it, then epoxy resin, prepared with a plasticizer and hardener introduced into it, is applied to the entire area of the fabric, as evenly as possible, and ironed. The viscosity of the heated resin decreases, thanks to which the binder well impregnates all layers in the fiberglass package. In those places where the binder was not enough, you can apply a new portion of the resin and iron again. It should be remembered that the optimal ratio (by weight) of binder and fiberglass is in the range from 40:60 to 50:50.
The more irons are used for ironing (it is more convenient for two to work), the faster the plastic turns out. Irons must be periodically cleaned of adhering resin with a sharply sharpened shoe knife or a piece of iron blade from a planer. The process of partial polymerization occurs after 20-30 minutes, while the material becomes rigid. You can not hold the iron in one place, as the heated area can strongly stick to the iron and the plastic blank will be unusable.
After the material becomes sufficiently rigid, but it can still be easily cut with a knife, leaving smooth cut edges, a template is applied to the fiberglass sheet and a sheet of future sheathing is cut along the edges along it. The edges of the boat hull set, to which the plastic will be glued, are pre-coated with epoxy glue. The ends of plywood frames have to be lubricated with glue several times. Then the plastic blank is placed on the set with tracing paper outward and fastened to it with small nails, ensuring a snug fit of the surfaces to be glued.
Tracing paper from the skin is subsequently removed with sandpaper. This can be done with a drill by sticking the skin on a fiber disc.
If, when laying the sheet on the set, it will sag between the frames, then it should not be glued. It is necessary to attach the workpiece vertically in the sun or near a steam heating battery to continue the polymerization of the binder. At the same time, it is necessary to periodically check that the workpiece does not become so rigid that it will be difficult to break through the plastic with small nails or it will be difficult to bend the sheet along the contours.
Thus, the entire surface of the hull, starting from the stern, is covered with pre-glued sheets. On stringers, the edges of individual sheets are glued end-to-end; on the frames due to their small thickness - overlap. The overlapping of the edges must not exceed the thickness of the frame plywood.
Joining the edges of fiberglass sheets on stringers (a)
and frames (b)
1 - sheets of fiberglass; 2- epoxy putty; 3 - stringer;
4 - nail; 5 - frame.
Then all the irregularities are puttied with epoxy putty and the body is allowed to stand for two to three days. After that, the body can be sanded, and then glued over with additional layers of fiberglass until desired thickness skins. When applying the last layer of fiberglass, a coloring pigment is added to the epoxy resin. Next, the skin is polished, if necessary, painted, turned over and work is started inside the case.
The boat built by me in this way has already been sailing for 8 navigations. Its length is 8.5 m, the height of the board is 1.2 m, the width is 2.6 m; engine - "ZMZ-53". During operation, there were several cases of collision with driftwood, and although the set received damage from strong impacts, there was no leak. The set does not lag behind the skin, and repairs after meeting with a driftwood do not require a lot of time. Now I am finishing the construction of a ten-meter yacht in the same way. There is no doubt that the construction will be light, strong, durable.
boat from pvc pipes do-it-yourself is a simple design. Its manufacture will cost quite inexpensively, but you can get a lot of pleasure in the summer swimming season. Such a structure can be made from plastic materials on their own. It's not a difficult job.
PVC pipe is the most convenient option for the design of products with their own hands. These products are perfectly fastened with glue or soldering.
Even when the boat is damaged during use, there is no need to be upset. Such a repair on your own will not be difficult. Using the same glue, they simply patch the damaged area.
To the above, it must be added that the construction of such a boat with your own hands is a very interesting job.
It’s a good idea to first make patterns of reduced sizes, and glue such a design from ordinary plastic bags. With such work, you can “feel” the material, which means that working with full-scale dimensions will be much easier.
After working out the patterns, they are proportionally increased. Masters advise to check the compatibility of the blanks by completing the design in natural dimensions from polyethylene.
This, of course, will take extra time, but it's worth it. If there are any errors in the calculations, it will be clear on initial stage, and do not have to spoil expensive materials.
Boat made of plastic pipes
A home-made boat made of PVC pipes confidently occupies a leading position among do-it-yourself crafts made from this material.
The most common plumbing preparation House master can turn it into an original watercraft on its own.
Work sequence:
- Frame. PVC blanks, with a volume of at least 2.7 cm, are cut into four parts. Two two meters and a half each (for the upper part), and two with dimensions of 2.7 m (for the lower part). These pipes will serve as the supporting part of the structure.
- Each end of these blanks should be cut at an angle of 45 degrees.
- Next, cuts are prepared slightly smaller with the following dimensions: 2 by 0.7 m, two by 0.6 m, two by 0.4 m and two by 0.35 m. These parts become supports for the boat frame.
- The support pipes are attached to the frame. The ends of the blanks must be fastened tightly, otherwise everything will fall apart and go to the bottom. Can be used for fastening adhesive tape or epoxy. For reliability, you can drill holes in the tubes with a drill and fix the structure with copper wire.
- being prepared wooden plank with holes, and is fixed on the bottom of the support frame. Plastic ties are used for fastening. The chair is attached to this board with the same fasteners.
- After that, the frame is covered with a tarpaulin. It must be waterproof. It is laid diagonally, and all protruding places are wrapped in the inside. The tarpaulin is attached to the frame with plastic clips. If there are rings on the tarpaulin, then you can attach it to the frame after holes are made in it for this. All folds must be stretched as much as possible. This will prevent unnecessary resistance while moving through the water.
Keel
The keel made of a PVC pipe for a boat is used to endow the watercraft with increased stability. Most often, the keel is on options using an outboard boat engine.
The keel is installed so that its working part is in the bow area of the floating aid. From amidships to the stern, the keel goes to "no".
Another advantage of installing a keel is that it partially raises the bow of the structure. And this, in turn, prevents splashes from entering the boat during a large wave.
Keel making
A homemade keel for a boat made of plastic pipe is simple. All the material that goes into work is durable, light weight and low cost. For a punt, such a keel is ideal.
After detailed development and verification of the drawing, you can begin practical work to create a framework. You can fix the frame with the methods already proposed above, or you can use a soldering iron for plastic products to work.
Working with such tools is not difficult. Even a person who has no experience in this field can cope with these works. .
Buying for a one-time job in order to weld the frame, this tool is not recommended, justifying this with economic unprofitability.
Better for fastening the frame from plastic pipes use a rental device. This service is offered by shops that sell soldering irons.
prefabricated frame, soldered with a soldering iron, will serve long time. In addition, each joint of the frame will be characterized by high strength. So with your own hands you can make a very durable structure.
Buying such an awning is not a pleasure cheap, so many fishermen equip their "submarines" with awnings, which are produced with your own hands And.
The most simple design- this is an awning that is attached to a frame fixed on racks. All this can be done from PVC pipes.
The work is done as follows: a tarpaulin is fixed to the frame at the end or pvc fabric. PVC pipes are lightweight material, which will not become the total weight.
At the same time, they are strong enough, and the frame will not break in case of accidental engagement with branches or shrubs hanging over the water.
The design of a do-it-yourself PVC tube tent can be very different, it all depends on the size and shape of the product, and on personal preferences.
A boat made of PVC pipes with your own hands will become unique if you decorate it additionally. Many pay special attention to this moment, for example, they paint acrylic paints, sheathed with painted plywood sheets and more.

After such events, a hand-made creation will definitely be unique and memorable. The whole design will not require a large amount of finance, because store counterparts are much more expensive.
A little patience and perseverance spent in the design process will bring great pleasure from relaxing on the river.
Fiberglass boats are an excellent alternative to inflatable boats due to their durability. Products from AkuaBoat are distinguished by worthy characteristics. They are made according to the parameters required by the customer, and in the shortest possible time. Fiberglass boats have long appeared on the market for such proposals, but over time the manufacturing process has been constantly improved. As a result, the vessels acquired stronger sides and new performance characteristics. Boats and boats built on the basis modern technologies in many ways superior to their predecessors of the last century.
The product consists of several materials with different characteristics:
Polymerizing resin for bonding;
Elastic fiberglass that takes any complex shape;
Moisture resistant plywood.
These materials complement each other perfectly, resulting in a heavy-duty fiberglass boat hull.
Design
Before the manufacture of the vessel, it is necessary to draw up drawings. This process is carefully coordinated with the customer, all details are discussed. After the approval of the project, the body is made. When designing, the rigidity of the material is taken into account, it is taken into account that the bottom must be perfectly flat to prevent deterioration of the performance of the fiberglass boat on the water.
Design requirements
The versatility of fiberglass makes it possible to produce durable and lightweight products from it. Fiberglass boats for high-quality operation should have the most rigid hull. It is also impossible to allow air to accumulate between the fiberglass, so it is applied evenly in 5-6 layers and carefully smoothed out, removing air between the layers.
The process of making a fiberglass boat
Reinforced material and polyester resin create a decorative and protective hull. This is preceded by several steps in the process:
Processing the matrix with a special tool that prevents resin from sticking to it.
Preparation of fiberglass and cutting it in accordance with required dimensions.
Applying layers of fiberglass and binder to the matrix in turn, and forming the body of the future product.
To strengthen the hull of a fiberglass boat, a power set of longitudinal rigid structures and frames is recruited.
The floor is installed using moisture-resistant plywood and several layers of fiberglass.
The fiberglass boat is removed from the matrix and polished. The ship's hull is being painted.
Advantages and disadvantages of fiberglass boats
You can make a ship of any configuration. Thus, it is possible to enhance the driving performance of a fiberglass boat, its speed, controllability and reduce fuel costs.
Such vessels are shockproof and are not afraid of temperature changes.
The bottom of the product is resistant to abrasion.
Easy maintainability.

People have been fond of fishing for a long time. It is always good to sit by the river with a fishing rod in your hands, relax in nature and breathe fresh air. But a lot of fish are found in deep waters, far from the shore, so the desire to have good boat naturally, especially since the options for her own production much is known today.
Boats are different: wooden, rubber, their PVC, fiberglass. What is good about new fiberglass, what are its advantages and disadvantages, how to build a boat out of it yourself, we will find out in more detail in this article.
fiberglass boat
Fiberglass is considered the cheapest and most reliable material for the production of boats. It is not affected by dampness, mold, fungal infection. Rodents do not feed on the material, so the boats are well stored in garages, any warehouses. The main thing is to glue the fiber correctly during production so that there are no gaps and moisture penetration into the case.
Advantages and disadvantages of fiberglass boats
The main advantages of the material include:
- respectable appearance;
- reliability;
- durability;
- water resistance;
- affordable.
Boats have many design advantages:
- The ability to change the oil in the engine in full. A little, filled below the maximum level, begins to foam, the motor overheats.
- It is possible to make a boat both with a keel and with a flat bottom, which is very convenient for use in shallow water.
- It is possible to make a more complex contour for the hull, which will significantly increase the ship's propulsion, it will be easier to control it. When switching to high power, the motor will not be needed, it will significantly decrease.
- Fiberglass is not afraid of sudden changes in temperature, is not erased when it comes into contact with the bottom of the river, and is not damaged by impacts.
- Holes are not difficult to repair on their own with the help of epoxy resin and fiberglass.
- These boats do not need to be pumped up, they are not afraid of punctures, cracks. In the presence of foam in the construction, as well as sealed cavities in the boat filled with air, it is simply impossible to sink the boat.
- The manufacture of the boat, as well as the contours of the hull, can be of almost any configuration.
The main disadvantage of the boat is its relatively large size; transportation is not possible without.
Design requirements
Fiberglass is unique material and is perfect for homemade boat production. Comfort, lightness and durability are the main qualities this material. The same applies to construction. Building fiberglass boats is easy, the main thing is to glue the fiber correctly to make the boat waterproof on the water.
The requirements for the design are:
- Maximum rigidity of the sides of the boat. The thickness of plywood is used at least 1.2 cm, superimposed in a double layer.
- The edges of the sides must be perfectly even, otherwise the boat will be unstable on the water. For this, the sides are puttied.
- Fiberglass laid in molds must be lubricated with wax.
- Air should not accumulate in the material, so fiberglass is applied to the matrix in layers, in 5-6 layers.
A fiberglass boat needs to be puttied and painted so that it is well stored in the future, does not succumb to mold and fungus infection.
Design
Manufacturing homemade boat starts with a drawing. You can view the drawings on the Internet, or develop it yourself using the AutoCAD program. Also, according to the drawing, a matrix is made. For its production, you need a blank or a mold. When designing, the rigidity of the material is taken into account, the alignment of the sides to perfect evenness so that there is no roll on the water.
Matrix manufacturing
The matrix is considered the most difficult stage in the manufacture. For its production, you need to acquire glass mat, rollers, brushes, sandpaper, polyester resin, grinder, vacuum cleaner, drill, scissors.
Process:
- attach frames to the frame;
- after installing the frames, plywood sides are attached. The nose of the matrix must be firmly attached to the board;
- the matrix must be rigid, so for the edges of the sides you need to pick up two-layer plywood, 12 mm thick;
- for evenness, the sides are leveled and sanded;
- polyester putty is applied to the matrix;
- the boat should have even sides, so it is wise to use a template spatula;
- it is important to make the markings on the boat correctly, its shape must be perfect;
- then we move on to the wooden keel, its presence will make the course of both the rowing and motor boat smooth, easy, it will not storm to the sides;
- the keel made of wood is covered with polyester resin on top;
- in order for the surface of the matrix sides to be ideal, the keel must be removed;
- bring the sides to perfection and the ideal shape of the matrix;
- the glass mat must be rolled to the sides, for this it is laid first on one side, then on the second;
- nipples are built in to extrude the boat from the matrix;
- in the presence of fiberglass harnesses, their matrix also needs to be adjusted to the place of their destination.
boat making
boat making is key point during its production. You need to stock up on gelcoat, polyester resin, glass mat, scissors, release wax, rollers, hardener, oars, sandpaper, oarlocks and oarlocks.
- according to the technology, the matrix is coated with a completely release wax in 4 layers, after which a gel coat is applied for the outer layer of the boat;
- fiberglass harnesses are installed parallel to the sides of the boat;
- for rigidity and strength of the structure, the glass mat is rolled in 5 layers;
- excess fringe is cut off, harnesses are glued with glue;
- oarlocks are screwed;
- the sides of the boat are thoroughly sanded with sandpaper;
- the finished boat is loaded onto the trunk;
- outside and inside the boat can be painted with a gel coat, but this is not at all necessary.
Using this sequence in the manufacture of the boat, the design will be light, strong, stable on the water, durable and very attractive. The back bank does not need to be made too narrow. The seats will remain buoyant even if the boat capsizes completely on the water.
The fiberglass hull of the boat is similar in structure to reinforced concrete structure. Fiberglass is an elastic material, it can be bent, given any geometric shape.
The material is durable, lightweight, unsinkable. That is why fiberglass has replaced wood and is widely used in the construction of boats of any modification and design.
By following clear instructions, it is not difficult to make a boat with your own hands, and a fairly light and easy-to-use vessel will help for many years. good rest and good fishing.
