How to make a boat?

To buy a boat, a boat or other floating means, not everyone can afford it. Not everyone is satisfied with the characteristics of the samples offered by the industry, and the craftsmen, who want to do everything with their own hands, have not yet transferred. In our article we will tell them how to make a fiberglass boat, as well as how to build a hovercraft.

How to make a boat from fiberglass

Start with a set of housing. This work is best done in accordance with professional drawings, especially if this is your first product - then you will not need to redo it. The hull of the future boat must be sheathed with thin plywood, after which it is tightly pasted over with fiberglass in several layers. It is important to use fasteners (bolts, etc.) exclusively from stainless materials - bronze or brass. Fiberglass before use is annealed with a blowtorch to a light brown color. Without this, the material is poorly impregnated with epoxy or polyester resin, which subsequently will result in the weakness of the case.

When choosing a resin, it should be borne in mind that although it is harder to work with epoxy, it is much stronger than polyester.When glueing out the first and several subsequent layers of skin, one cannot do without glass clap - coarse fiberglass. It is better to put satin fiberglass on the outer layers of the case, on the upper layers - a glass fiber grid - a thin rare fabric well impregnated with resin. The finished body is carefully sanded and polished. Start this procedure before the final hardening of the resin. It is better to perform work in a respirator, while actively using power tools, since the described processes are rather laborious.

How to make a hovercraft

Compared to an ordinary boat, the hovercraft does not experience significant loads, since almost all loads are absorbed by a flexible enclosure. Therefore, to build the hull of such a craft is quite simple. The only thing worth paying attention to is the weight of the structure; the vessel must be extremely light. It is also important to pay attention to the aerodynamics of the future boat, since it will depend on this already very impressive fuel consumption.

The hull of the boat can be made of spruce slats, sheathing them subsequently with 4 mm plywood.Plywood is usually fixed with epoxy glue, but you should not glue it with a cloth because of the weight gain of the product. More advanced designers create their boats using computer 3d-technology. The flooding of the boat is achieved in several ways. You can install watertight partitions in the side compartments, and it is even better to fill them with foam plastic. Some place inflatable balloons under a flexible fence.

Power point

This immediately raises a lot of questions that each designer tries to answer independently. How many engines should there be? What will be their weight? How many fans are needed and how many blades will they have? At what angle does the angle of attack and how much will it ultimately cost? There can be no universal answer here due to the imagination of the designer and, consequently, the individual characteristics of each product. This stage of the construction of the hovercraft is the most expensive.

Build flexible fencing

This is perhaps the most difficult stage of the construction of the boat. Due to constant contact with the surface, the flexible fence wears out quickly,therefore, the best material for its manufacture - canvas fabric. Practice shows that such a fabric will need at least 14 meters. They try to increase the durability of the fence by resorting to all sorts of tricks, in particular by soaking the tarpaulin with aluminum powder diluted in rubber glue. It is important that a broken or worn flexible fence can be easily repaired.

Assembly of the hull and installation of the fence is performed on the future boat tilted up. Having unraveled the hull, proceed to the installation of the power plant. After that, you can bring to the engine control system and send the product to the test. The approximate dimensions of a homemade hovercraft: 3700 by 1800 mm. Board height - 600, pillows - 300 mm. With a weight of 120 kg and fuel consumption of approximately 15 l / 100 km. Such a vessel is capable of accelerating to a speed of 60 km / h.
