Boat homemade: the main characteristics

Sudomodelirovanie was popular even in Soviet times, young craftsmen of those times competed with each other in who will find the details better. Of course, the friends of the practical engineers, radio amateurs and telemasters, who were available for a wide variety of accessories, were winning, of course, often bypassing the specialized stores. Now with the advent of online markets of all sorts of things at reasonable prices from the Middle Kingdom, the search for details and components has come to the fore, and the creation of models is more subordinate to the author's fantasy and skill.

A little bit about creating models

For the first attempt, it will be more reasonable to find detailed drawings and instructions for creating a boat for radio control and stick to them, but for experienced craftsmen the problem of choosing a prototype or original body design will be more important than maintaining buoyancy and model control. There are options for quickly creating a water toy from a piece of foam and a couple of containers for food. The appearance of such products is far from ideal, but the characteristics are quite worthy. It is necessary to determine in advance what the goals of the mini-boat are, whether it is entertainment for a child for a couple of days off, a full-fledged model of an existing vessel for exhibitions, a copy for special competitions or a home-made boat for feeding fish and other tasks. Based on the tasks assigned to the product, it is necessary to determine which parameters play an important role, and which can be disregarded for the sake of more important ones.

Learning to Swim

The main characteristic for any water transport is buoyancy, this quality is achieved in two ways: using materials that are lighter than water, or creating a container protected from seawater. A homemade plywood boat can combine both ways of maintaining a boat on water. When creating underwater vehicles, the calculation of buoyancy and the implementation of its control will become one of the most time-consuming processes for the master. For surface vehicles, detailed calculations and tests are not so important, you can check the buoyancy in the bathroom while the homemade boat is still at the manufacturing stage. The very possibility of the device to stay afloat can be estimated "by eye" when designing. Ready-made schemas in the catalogs are tested and tested in practice, so when assembling by template you can trust the description.

Without rolls

Together with the buoyancy boat homemade must be resistant to the waves and when driving. The most important role in retaining the position is played by the shape of the hull. In order to improve the stability of the hull, a flat-bottomed version or a very stable version of the use of a catamaran - a double hull - can be chosen. For narrow models, the displacement of the center of gravity below the waterline is suitable, for this purpose a massive keel is made or the heaviest parts, like the battery and the motor, are placed in the lower part of the bottom. During the movement, the streamlined symmetrical shape of the vessel also improves stability and allows you to keep the direction of travel in the presence of extraneous noise such as wind and current. It is possible to use additional weights for leveling the roll.

Size matters

Do not ignore such an important characteristic as size. If for smaller copies of real ships the dimensions will depend on the details, the homemade radio - controlled boat for water competitions should have minimum dimensions for the sake of streamlining and speed. For the first trial products of beginning ship modelers, the size is not at all important, these products will be modified many times or completely redone if the passion is to their liking. The situation is more complicated with fishing, where the dimensions of the ship are completely dependent on the tasks assigned. Given the open reservoirs, the danger of being attacked by fish and the task of transporting the goods along the water, fishermen should not neglect size and strength.

Protection against water

The use of electric drives in modern floating devices implies at least protection from splashes. When using materials that are lighter in water at the base of the enclosure and the arrangement of electrical devices and connections above the water line, such protection may be sufficient. Use self-made boat in rainy weather with a metal casing or the location of the motor and wires below the waterline can only be made sure of its full tightness. Violation of this rule can lead to the launch of the boat in the middle of the reservoir, which, in turn, can lead not only to breakage, but to the complete loss of the floating toy.

Propeller, underwater blades or water?

The choice of driving force is also very important. If for the exhibition and decorative models everything determines the real pattern, then for other products the choice is quite large. Aerodynamic models are suitable for entertainment, besides, there is no need for a good seal: all electrical and running parts of the structure can be located out of reach of water. For durable high-speed boats, hydrodynamic systems are more suitable. Water jet engines are usually somewhat more expensive and more difficult to install, so most ship modelers prefer classic engines with direct transmission of a rotational impulse on the blades of the underwater propeller. Such systems require additional waterproofing of the transfer shaft passing through the housing outward directly into the water.

Swimming is nonsense, the main thing is maneuvers

Paraphrasing the well-known expression, we approached one of the most important parameters of water transport - the realization of the possibility of changing the trajectory of motion. Rotations for different systems differ not so much, for example, a controlled blade at the stern of the boat can serve as a handlebar for most models. For models of sufficient width and catamaran-type bodies, it is possible to provide two engines with separate control, which will allow them to turn, including them separately. You can provide for the rotation of the main propeller, this option is easiest to install on a self-made boat with an aerodynamic system.

And instead of the heart - a fiery motor!

Parameters of the main engine are extremely important in the manufacture of any boats. Exhibition models, pleasing to the eye, which for all their beautiful and long life can be launched only a few times, should not be equipped with powerful engines with increased life. Enough will be economical units of medium and low power, after all, water movement is a secondary task for such exhibits of a personal collection. Another thing - racing boats and fishing assistants, where the choice of motors should be approached much more seriously. Racing self-made boats, photos of which are presented in the article, have impressive engines.

Elements of a food

Wind energy is good for sailboats, motor boats require something more reliable. Given the management of radio waves and other features, the use of electric batteries and batteries has become a general rule for floating vehicles of this size. The capacity of the batteries may depend on the price, the load capacity of the hull and the power of the engines and other equipment installed on the homemade boat on the radio control. Do not forget about the control panel, which also requires a separate power source. Installing solar panels on the deck can significantly increase the period of use of the boat before recharging, but such power sources will greatly affect the overall price of the product.

Radio range and other

This parameter can be a key for fishermen and lovers of open water spaces. For use on small rivers, small lakes, ponds and swimming pools, inexpensive models of radio receivers and transmitters are quite sufficient, some can be borrowed from broken toys. Professional fishermen order special microcircuits for their boats with a good range margin, since radio communication can be worsened by obstacles and bad weather. In addition to all of the above, fishermen may be interested in other equipment for such boats, for example, echo sounders or night lights. Moreover, you can abandon the control panel by providing the boat with a GSM module and managing it from a smartphone or tablet computer. The modern market of parts and spare parts is ready to provide everyone with the most demanding and original craftsman.
