Projects, schemes and drawings of boats, boats, yachts for self-construction. Drawings for building a yacht


What do you think - is it difficult to make a radio-controlled yacht with your own hands?

If you think that it is very difficult, expensive and requires special knowledge, then you are wrong!

Of course, building an RC yacht for competitions is a completely different matter, for such a yacht you need a lot of experience, but you can build a small yacht for cruising on a nearby lake without experience!

You can download the drawings and a small instruction for the manufacture of the Footy yacht at the end of the article.

Manufacturing

In the original, the yacht is proposed to be made of balsa and plywood. It is possible only from plywood, for example, from fruit boxes - they are thrown in heaps near fruit markets and shops.

But you can also make it from the ceiling! It will only be necessary to make a power frame - cut a false deck from plywood with relief, which will connect the keel box, servos, mast mount and rudder mount.

By the way, it is also desirable to make a keel box from plywood.

However, an almost finished yacht hull can be obtained from a bottle!

Here are examples of such yachts


They even walk on water!

servos

To control the rudder of the yacht, any 8 gram servo will do. But for sail control it is better to put a more powerful servo. The usual 8g of pull may not be enough to tighten the sail in more than moderate breeze.

Of course, it is best to put a special winch servo, but they are expensive, you can get by with an inexpensive 16 gram servo.

Here is an example of how the servos are located in the hull of the yacht

Sails and rigging

You can not bathe with the manufacture of sails and rigging, but put an ordinary triangular sail on the bow of the yacht.

Or like on a Chinese junk:

You can make such an oblique sail:

For the manufacture of the mast, it is best to use carbon tubes, if not, then aluminum. This is almost the only thing you need to look for and buy.

In the most extreme case, wooden ones will also go, but firstly they are heavy, and secondly it would be desirable to process them into a cone - so as not to drag extra cargo.

In general - the less weight above the waterline and especially at a distance from the water surface - the better the yacht sails, since there is no "pendulum from above" that shakes the yacht with voices. There are probably a lot of other factors, but everyone agrees on one thing - to make everything that sticks out of the water near the yacht as light as possible!

Bulba

Bulba is that heavy thing at the end of the keel, cast from lead. Lead can be taken anywhere, before there were a lot of old batteries lying around garage societies, lead could be taken from them and melted down on a small fire in a tin can :)

Now you may have to purchase it separately.

It's easiest to buy shots of any caliber (or number?) at a hunter's shop, or pickup weights at an angler's store.
There is also lead at every wheel balancing station. That's just the ratio of prices, I can not say anything.

The rest is in the file with the drawings - and cutouts for the manufacture of the hull and drawings of the sails and how to mount the rigging.

I hope you get something like this:

Can't imagine your life without the water element? If you want to have a pleasant and useful time, provide yourself with an exciting period in life by starting the construction of a yacht.

Foreword

If you prepare carefully and with great enthusiasm for the process of building a yacht, then the hour will come when you will triumphantly board your vessel to go on its first journey across the expanses of water.

First you need to choose a project, having previously studied as much literature as possible on the topic of interest.

Bright prospects

By actively looking for the optimal project, you will bring the time of construction of the yacht closer. It will change the usual course of your life, will allow you to discover new perspectives and horizons. You can go on a romantic trip or arrange unforgettable family holidays, invite friends or indulge in reflection alone, communicating only with the blue element.

After the construction of the yacht, you will ride "with the breeze", you will be able to dive from the ship in a quiet harbor, taking your scuba gear with you. You can go water skiing or just enjoy fishing.

New expanses and shores will open their secrets for you.

Where to begin

When selecting drawings of plywood structures, pay attention to the presence of information such as:

  • node drawings;
  • drawing details;
  • a description of the assembly technique, which will be available even for beginners.

Many men are familiar with the dreams of a yacht to conquer the expanses of water on it. Not everyone can afford to build a fiberglass yacht. This does not mean that wishes are not destined to come true. You need to make an effort, spend time, study yacht construction projects, but as a result, you will be able to create a masterpiece that will surpass expensive ships in quality and beauty.

You can not start with large-scale projects, but make a simple product. Then you can understand the principle of creating a yacht and realize it in natural size.

About the features of the building

There are two ways to implement a plan to build a motor yacht. It is much easier to carry out the main process if you first complete the maximum preparatory work to create blanks. It is more difficult to work from scratch.

In the modern shipbuilding market, there are many specialized companies offering varieties of such assembly kits, which include a list of necessary parts. Of these, the construction of a motor yacht will be directly carried out.

In order for everything to be done correctly, the blanks are accompanied by detailed instructions and drawings. In addition, it is important to know about the correct assembly and strict adherence to the manufacturing technology of the vessel.

Choice of purchase options

If you decide to purchase ready-made elements and assemble a yacht from them, you will be interested to know that pre-sale preparation is carried out for all parts.

As a rule, in production, the model is fully assembled to check the quality of the fastening of the joints and compliance with the dimensions, and then the vessel is disassembled, packaged and sent to the customer. The buyer will have to go through the assembly process again and be sure to glue the structure as indicated in the manufacturer's recommendations. To do this, you will need to carefully study the information provided on building a yacht with your own hands.

Choosing the Harder Path

If you decide to work with the independent construction of boat yachts from scratch, it will be much more difficult. But no less interesting. Just with this choice of actions, everything will depend on your attentiveness and skills. If you are well prepared and armed with a wealth of knowledge, building a yacht yourself can be more profitable for your budget.

Do not forget also that you will need special equipment to create a ship yourself.

Stages of building a ship from scratch

First of all, when building yachts, take care of the presence of a spacious room where the process of creating a masterpiece, called among professionals a boathouse, will take place directly. Acquire the necessary tools and equipment. It is better not to save on this, because you want to get a quality result. In addition, the amount of time that can be spent with decent equipment of the workplace is important.

Assemble the slipway according to the dimensions of the vessel. This is where it will be installed. In the process of creating a platform, coniferous wood beams are laid on a plot of a flat prepared surface. This is done in rows of two, followed by tying the structure and obtaining a surface that will be located exactly horizontally.

Continuation of work

Take care of the preparation of project documentation. Its independent development by an inexperienced specialist is practically impossible. In order not to risk materials and the end result, it is recommended to entrust the production of project documentation to specialized organizations.

Also around the clock at your service is the Internet, where you can study not only the drawings, but also the design of yachts, read useful information and reviews of experienced people on this issue.

We prepare materials

Perform lumber harvesting. This is a very important stage of construction work, since the better it is organized, the higher the strength and navigability of the future yacht will be.

To create a structure, pick up two types of lumber: from a knotless softwood board and a bar of a harder breed (oak, ash).

It is important that the moisture level of the wood is no more than 12-20%, which provides protection against deformation. On the slipway, mark the line of the stem and the places of the theoretical position of the frame frame. According to these signs, installation work with all structural elements of the vessel will be carried out.

Assembly

It is possible to assemble and glue the frame frames in accordance with the outline of the vessel. This is done on a special type of fixture, which is a template.

Creating a frame frame

Mark the working plaza on plywood 10 to 12 mm thick. If you want to simplify the task, create closed frames containing underdeck beams.

When assembling a frame frame with a transverse shergen-bar, use special screws. For assembly, provide yourself with special stops that will fix the position of the frame, depending on the initial markup.

Please note that when forming all bulkheads, it is necessary to combine them with the frame frame, and sometimes its replacement. To install the stem blank, it is important to maintain the dimensions of the angle of inclination with respect to the horizon.

To collect the keel beam, pick up the bars and fasten them to the surface of the stem with a button, and to the surface of the floors - with screws and glue.

For the manufacture of stringers, select glued pine slats and mount them on the surface of the stem and frames with self-tapping screws and glue.

The installation of stringers is completed by a mandatory shallowing procedure, which is performed to identify all inconsistencies with the ship's contours and eliminate defects.

When the hull skin is created, sheet bakelized plywood is taken and cut into a pattern. Then they are mounted with stringers on glue and self-tapping screws, slightly drowning them inside the plywood.

Checking the quality of work

The installation of the casing is completed, now it is necessary to carry out a number of control measurements of the contours and process the surface along the territory of a single radius.

To remove, use an abrasive tool. To give rigidity and tightness to the surface, the skin must be pasted over in several layers with T1-GVS-9 fiberglass. For this purpose, an epoxy composition is taken.

When the first layer hardens, the surface is covered with fiberglass with a polyester resin backing. So perform up to ten layers.

Recruiting the deck

Having turned the base of the yacht over, they proceed to the implementation of the longitudinal set of the deck, where the deck flooring is installed. In order for the layers to be strong and airtight, it is important to glue the body with fiberglass, alternating it with epoxy and polyester binders.

Sanding and priming

When all layers have hardened, it is necessary to grind and prime the resulting surface. To perform painting work, a special moisture-resistant paint is selected, which will provide maximum protection against sea water. Then the surface is forcibly dried.

Final stage

It remains to complete the interior decoration, install additional equipment and a set of sailing weapons. These procedures are carried out when the final stage of construction work has come. If you want the yacht to have a power plant, contact the experts. This stage is especially responsible, as it requires additional knowledge.

We assemble the yacht according to the blanks

If you decide to quickly achieve results and not take risks when doing all the construction work from scratch, purchase factory blanks for the yacht and assemble the ship yourself, following the recommendations for building a yacht using the assembly kit. This is similar to the assembly of the designer, only more responsible and requires clarity and reliability of all fasteners.

Preparing documentation

Before starting work, it is also important to carefully study all the documentation provided in order to prevent serious errors that may be fatal in the end. Explore DIY yacht designs.

Assemble the yacht, starting with the fact that you first connect the frames and the keel. A satisfactory result will be shown if it is possible to assemble this structure in the form of an integral connection.

ship plating

Install the springers on the frames. They will be attached to the ship's skin material, consisting of a special type of plywood, resistant to moisture.

Please note that this assembly requires a traditional position. It is required to install the vessel with the keel up. This will achieve the required level for dimensional accuracy. You can also create the shape of the ideal contour of the vessel.

Thanks to the sheathing made of a special type of plywood, which is resistant to moisture, high strength is ensured in the construction of the vessel.

Fiberglass can be used to provide sealing. It will be mounted on the surface of a special moisture-resistant epoxy composition. Gluing is carried out in several layers. After everything dries, a uniform waterproof surface will be obtained.

To ensure an attractive appearance and create additional protection, treat the surfaces with special varnishes and waterproof paints.

To paint the inside of the yacht, you will also need waterproof paint. After that, you can lay the deck.

Testing

The final stage of work is to complete the final finishing of the hull, complete the vessel with the necessary equipment and sailing equipment. Be sure to test in a working environment. This is a necessary condition in order to ensure the safety and reveal the seaworthiness of the vessel. It is important to timely eliminate some shortcomings and shortcomings.

Afterword

To build a ship completely, you need to tune in to a large amount of work with a high level of responsibility.

Provided that it is properly operated and properly cared for, it will delight its owners for a long period.

Discover the versatility of the wonderful world of nature, enjoy travel. But if you are not ready to build a real yacht, you can think about building a model yacht yourself. This will form the foundation of knowledge to understand how a yacht is built and ensure a thorough study of the technology, as you can look at designs for boats and yachts for self-build. Decide - and everything will work out for you.

For lovers of modeling, sheets of pressed and glued wood veneer have always been one of the most sought-after materials. They are easy to cut, perfectly processed, drawings of ships made of plywood are easy to find on the net, and therefore many craftsmen begin their acquaintance with the modeling of various ships with plywood patterns.


Making models with your own hands is a very difficult task, requiring a significant amount of knowledge and a certain skill. In the article we will talk only about the most basic techniques, and you will hone your further skills yourself.

Work materials

If you want to make a small ship model, you will need the following materials:

  • Wood - cedar, linden, walnut or other wood, preferably soft and not fibrous. Wood blanks should be smooth, without knots and damage. Wood can be used both as a material for the main elements of the model (hull, deck), and for fine detailing.
  • Plywood is perhaps the most sought after material.. For ship modeling, either balsa or birch is used, since it is these types of wood that provide the minimum number of chips when sawing. Model ship plywood, as a rule, has a thickness of 0.8 to 2 mm.

Note! Sheets of beech veneer of small thickness are sometimes used as an alternative to birch veneer: although they are inferior in strength, they bend much easier.

  • Veneer - thin plates of natural wood of expensive species. As a rule, it is used for veneering, i.e. pasting of a surface from inexpensive material.
  • Fasteners - thin chains, laces, threads, brass and copper studs.

In addition, we will definitely need wood glue, cardboard and tracing paper for transferring templates, etc. Fine detailing is made of metal casting. As an alternative to metal, colored polymer clay can be used.

Making a souvenir boat

Preparation for work

Any work begins with preparation, and modeling will by no means be an exception.

  • First we need to decide what we will build. If you have not previously dealt with ship modeling art, then we recommend downloading ship drawings from plywood on the net: as a rule, they contain all the necessary information and are understandable even to a beginner.

Note! Kits are available for sale that allow you to assemble a vessel from finished parts. For beginners, such kits will be interesting (although the price of most of them is very significant), but it’s better to master the technology from the basics.

  • After analyzing the drawing, we check whether everything you need is available. In principle, if something is missing, then it will be possible to buy it a little later, because building a ship (albeit a miniature one) is not a quick job!

  • After printing the drawing, we make templates for the main parts.
  • Transferring templates to .

Cutting and assembling parts

You can cut blanks both with the help of a manual and with the help of an electric model jigsaw.

The latter is more expensive, but with it you are less tormented when cutting out small details:

  • We make a starting hole in the plywood sheet, into which we insert a file or a jigsaw blade.
  • We cut out the part, trying to move exactly along the marked contour.
  • We process the sawn workpiece with a file, removing small chamfers along the edges and removing the inevitable chips and burrs.

Advice! Working on one element (deck, sides, keel, etc.), we immediately cut out all the parts necessary for assembly. So we will spend much less time, and the work will move faster.


When everything is ready, we start assembling our ship.


  • First, on the longitudinal beam - the keel - we put on the transverse frames. In the lower part of each frame, a groove is usually provided for fastening to a plywood keel.
  • For connection, you can use standard glue, or you can use special glue mixtures designed for ship modeling.
  • We attach the upper parts of the frames to the deck. For simple models, the deck is a single sheet of plywood, while for complex ones it can be multi-level.
  • After the glue on the frames dries, we begin to sheathe the sides with thin strips of plywood. The thickness of the material should be no more than 1.5 mm, because only in this case we will be able to bend the skin without the risk of damaging it.
  • For bending can be heated and humidified. After that, the material will bend without difficulty, and over time it will acquire a stable shape.

Note! The case for painting can be pasted over with a solid sheet. But to imitate plank sheathing, it is better to use strips up to 10 mm wide (depending on the scale).


  • We fix the glued plywood with clamps and clamps and leave to dry.

Finishing

By and large, this is where carpentry ends and art begins.

When the case is assembled and dried, we need:

  • Make from thin plywood and fix deck superstructures.

  • Increase the sides so that they protrude above the deck plane.
  • Paste the deck surface with wood veneer or draw it with an awl, imitating plank sheathing.
  • Make and install all the small parts like the steering wheel and steering blade.
  • Fix the masts with all additional devices (the so-called spars), set the sails and stretch this entire structure with the help of rigging threads.

In conclusion, all plywood parts must be stained and varnished. This will provide our souvenir with at least a couple of decades of safety.

Output


Almost everyone can make a simple boat out of plywood with their own hands - enough patience and minimal skills in working with a jigsaw (read also the article). But if you want to implement a complex drawing with many small details, then you will have to work hard. That's why we advise you to start with the simplest models, gradually increasing your skills!

Krokha 15. This is the name of a cruise yacht, a family mini yacht.

This version of the vessel is good for an independent type of construction. The vessel is small in size, but this does not affect its popularity in any way. The yacht is quite comfortable and practical for a family holiday.

The yacht is located so that it has four berths, that is, it is suitable for a small family. There is also a table for a family dinner. The simple but effective construction of the yacht makes it very comfortable for a pleasant pastime.

Sailing equipment on the yacht is very high quality. The work of a sailboat is made simple and not stressful, thanks to the furling on the staysail. The baby is a very stable vessel and, by right, can be called a seaworthy vessel. If the weather turns bad or a storm begins, the boat may well continue its journey under menacing waves. In addition, the trailer and transportation is also provided.

The structure of the yacht is wooden. The casing is made of plywood. The amount of work on the hull construction is not at all complicated, the period of time is spent a small. Manufacturability of the highest quality case. The materials are simple but very good quality. There is not much equipment, but the essentials are there. All the advantages taken together allow you to enjoy your stay on this wonderful vessel.

Scheme for building a yacht

Man is able to build such a vessel himself. You only need to have a strong desire, and skills are not difficult to acquire. If your monthly income is very modest, then you can still build such a yacht. It is possible to create such a version of the vessel that the steering wheel control will be designed for two rudders. You can also make a cockpit with a convenient passage to the stern. This option is especially good for families with small children. Also, this option is appropriate for those people who have oversized body sizes.

In some versions, the cockpit is open from the stern. Although there is only one steering wheel, it is located on the transom and it has a tiller. Thanks to this design, space and comfort are added to the cockpit.

Independent construction of a yacht according to the Krokha-15 project

The age of the ship is quite solid, given its size. But one should not see shortcomings in this phenomenon, on the part of the ship's seaworthiness. There are several important reasons for this. What are these reasons? First, it is a well-known fact that heavier boats tend to be more comfortable and stable on the water. Especially if the sea is rough, then ships with a heavy weight are less susceptible to the harmful effects of stormy weather on the ship itself and passengers. If there is a wave of a counter nature, then this may stop some ships. But the boat is powerful in strength and gravity, it is easier to stand, and not only stand, but will also move forward towards the intended goal.

Yacht drawings






















Also, the weight of the vessel also affects the area in which the boat can sail. The weight allows you to operate the boat, and with complete safety, both in open waters and in coastal marine areas. Light boats in bad weather rush to shelter places. But, the yacht we are talking about is not afraid of any weather.

The stability of the vessel is also given by the weight that the ballast has. And the design of the boat is solidary, although it does not consist of exotic and very expensive materials. The materials that are used for the construction of this vessel are very simple, but proven by experience and time at the same time. Materials and construction allow the vessel to be distinguished not only by its strength, but also by its durability.

In addition, it is very comfortable and pleasant to relax on a ship made of wood, rather than in an iron or metal can. Agree, it is not very comfortable in a ship made of cold and frosty materials. If you relax, then you want to do it with maximum pleasure and satisfaction. The buoyancy blocks of the vessel are finished with foam plastic, and the lining from the inside of the hull is covered with foam plastic.

What is achieved through this? If suddenly the yacht begins to flood with water, then you can not worry, since the above work done has ensured the ship's unsinkability in such situations. Therefore, if you decide to sail on your own, without the help of a specialist, such a vessel will be the most suitable and reliable for you.

There are different types of crumbs 15. For example, there is a pocket type of such a yacht. The purpose of this yacht is to sail on the territory of coastal open and inland seas. Also, such a boat is suitable for sailing in the area of ​​​​reservoirs and lakes, as well as in the territory of rivers with inland waterways. This yacht is also often used for family cruises.

When there are children in the family, the journey will be very entertaining and exciting for them. The degree of safety and high comfort on a ship of this type is extremely high. Therefore, you can safely go on a trip with the smallest children. The cockpit in the boat is safe and protected from bad influences.

The cockpit has a helm control post, which is good. For a good rest on the ship there are tables of a portable type. There is also a swimming area. This will give your holiday fun and laughter. On the deck there are very strong and reliable sides, holding on to which you can not be afraid to stumble and fall. There are special places for sunbathing. Fans of this type of recreation, probably already want to try such a pleasant pastime.

Consider this version of the yacht, in which there is only one steering wheel on the transom. This model is very simplified. But, despite this, this model of the vessel is distinguished by its practicality. And there are quite a lot of fans of just such a variant of the vessel.

In the construction of such a vessel is very simple. In terms of weight, the yacht is slightly lighter than the options already considered. But the difference between such a yacht is solely that it has one steering wheel. In all other respects, it remains reliable and practical, applicable and effective. If you raise the rudder blade, then it will be possible to approach the shore, stern closer. In this you can see the advantage of this vessel.

Now let's talk about a multi-purpose boat. This type of boat can interest every person. If you want to travel with your family, this option is for you. If you want to go fishing or watch the underwater world, this option will also suit you. There is a very wide platform in the stern of the vessel.

Therefore, fishing is very convenient, as well as descending into the water is very comfortable. You can easily dive into the water, and you will see the beauty of the underwater world. If you are fond of sailing races, then such a vessel will also suit you. Just one good tip. Equip the vessel with the highest mast so that the sail area is maximized. And you can order the keel so that it has maximum depth.

If you are a yachtsman, then you will be interested in a dinghy variant boat. It will suit the conditions of navigation on not very large lakes, as well as on small rivers. Mounted steering wheels for turns will be very useful for fans of this type of entertainment. If we talk about material costs, then the dinghy is a more expensive option.

Building such a ship is not cheap. A keel yacht will cost less. But, of course, the best and most practical option is still a dinghy. The only negative is that the dinghy cannot guarantee safety. And most people prefer calmness and confidence that the rest will benefit and not harm. Therefore, if you want to be sure of your safety if a storm starts, then you will not find a better option than a yacht.

Baby 15 is able to receive a certain number of people under its deck and shelter there. Moreover, this number is quite large. Therefore, during bad weather or just at night, there is a wonderful opportunity, without fear, to feel even more confident and calm.

If we talk about the comfort of rest on such a vessel, then a lot in the design brings unforgettable pleasure and pleasant memories. Lockers, beautiful design of all furniture, all this makes the trip beautiful. The fact that the tables are portable is also a big plus. If you wish, there is an opportunity to dine while watching the waves and the beauty of nature. Or maybe you want to sit in complete silence. The choice is yours. Conditions for a comfortable stay are provided in perfect order. And how exactly to relax, you choose.

Let's discuss the stability of the ship. What is its reliability? The stability is very high. This is possible due to the fact that the center of gravity, that is, the keel, is located quite low. And the mass of the boat, despite its size, is very large in severity. This factor also gives the boat stability. The stability index of this vessel is such that it can be classified as a marine vessel.

If it happens that by chance, due to a strong squall, you are suddenly put on the water with sails, and the hatch is open, then the entrance to the cabin will remain higher than the water level. Therefore, you absolutely should not be afraid that the ship will flood with water. You can see a kind of bulge on the diameter. This is an area of ​​stability, with increased stability. Therefore, if the cabin suddenly begins to sink into the water, then there will be a moment of additional recovery.

The weight of the vessel plays a rather large role in the stability of the vessel. This is especially true of schaertbrots. If the yacht is keeled, then safety will not depend to a large extent on the location of the crew. You don't have to worry about this situation.

As we have seen, a yacht can be of interest to different categories of people. Whether you are a family man, and you have a desire for the whole family to arrange a trip through the expanses of clean sea air, whether you are an avid fisherman who wants not only to go fishing, but also to experience real pleasure from it. Perhaps you are drawn to look at the underwater world, to see all the beauty of the excellent, beautiful world that exists below us.

What is inaccessible to the human eye often attracts and beckons. If you feel the emotions and feelings listed above, then you might consider building your own yacht. In addition, as mentioned earlier, this does not always require a lot of material costs. You can start with the simplest option that everyone can afford. And it will open up unprecedented opportunities for you and your family. The world is beautiful and you can make many discoveries for yourself. Don't dismiss this idea right away. Decorate your gray everyday life, add some bright and magical colors to them.

Have a nice and magical holiday.

The yacht "Dolphin" is designed for sailing on lakes and open sea bays with a depth of at least 0.7 m. The design of the yacht is designed for amateur construction. The sailing equipment of the yacht consists of a 10 m² mainsail. In calm weather, as well as when sailing in narrow straits and bays, the yacht can move with the help of an outboard motor mounted on the transom. Travel speed with outboard motor "Moskva" with a power of 10 hp. from. is 6-7 knots...

The experience of three navigations showed that, in general, the layout and structural elements justified themselves. In a small (less than 6 m) case, we managed to squeeze in something that, with a traditional layout, can only be accommodated in an 8.5-meter case. As my passengers usually say, "the inside is bigger than the outside"...

"Skat" has all the advantages and disadvantages inherent in three-keel planing hulls. With relatively small - "economical" dimensions, the boat is roomy and stable, it keeps well on a wave up to 0.7 m high. It is unsinkable (thanks to the foam); in an emergency state, Skat will keep all four of its passengers afloat ...
