The design for the alloy boats
Modern pnevmolodki different well-designed with a minimum of parts. Bottoms have elastic single-layer or double-layer. This gives sufficient rigidity, improves safety and reliability, increases the load capacity.
It is a maximum of half an hour. With the compressor is inflated for a couple of dozen minutes. Inside they are covered with a cloth, which has anti-skid. The seats are made of specially treated plywood, which does not get wet.
characterized by:
- an inflatable bead structure, consisting of several independent compartments
- Reinforced bottom and the bottom of
- flat or slightly keeled bottom design that is suitable for rivers in the mountains and in the shallows
- air valves in the inflatable element for inflating and venting air
- adjustable seats
- waterproof bag for clothes, food and so forth.
- manning the oars, oarlocks, bellows pump
This material is a high strength special polyvinylchloride tissue. Additionally is a thermoplastic coating. Bottom, which has serious burden may further be covered by a layer of PVC teflonirovannoy tissue.
Sutures connecting parts are glued strips of the same material on both sides, and that the product itself. Used for this polyurethane adhesive is extremely durable.
In addition, the production of varieties are rubber and neoprene, which are cheaper than PVC fabrics. However, rubber fabrics lack the strength and resistance to motor oils and fuels. It rot, abrasion and exposure to ultraviolet rays.
Alloy means used to move the water different contours or shape of the inflatable bead arrangement. They connect the bottom. This completes the construction, giving it integrity.
Distinguish ellipsoidal outline bead semiclosed, wherein the side cylinders cylindrical or rounded shape are placed in parallel, connecting the bow. Such models are called V-shaped. The corners of the compound differs from the specific types of boats.
When selecting funds for river alloy based on its capacity. Min - over 100 kg. In these boats travel uncomfortable. At intermediate bulk cargo weight not less than 200 kg, with a high - more than 300 kg. Increased capacity is not less than 600 kg. This is a suitable option to place group, preparing for weekly alloy.
Quite a few constructive solutions boat hulls involve the use of the volume of the beads under the personal items or equipment. With the vertical partitions suit isolated compartments. After loading the compartments sealed, and inflated with air.
Security cameras help special inflatable boards that provide additional buoyancy. They are formed by the creation of separate volumes of vertical partitions alongside or across it.
It is preferable to choose a boat propelled by oars. Sometimes, going on a trip on the river, a group of tourists takes a boat motor. It is often not justified. Preparing for rafting and choosing a boat, most importantly the right to determine the volume and weight of the goods required in the way, on the route of the river and the nature of the state banks.
Vydy boats for rafting
Before choosing the appropriate model to the alloy, it is important to have an idea about the types of the respective courts.
These types include:
- ordinary rubber
- inflatable kayak
- Court of PVC and other modern materials
- catamarans
- rafts
1. Inflatable model is considered a classic. It is extremely popular among hunters and fishermen, water tourists. It is relatively cheap, functional and unpretentious. This is an affordable option for the alloy. 2-4 local rubber boat is not difficult to acquire.
If the river flows through the plain, and the gentle shore, it becomes a reliable means of transportation on water. Not suitable for rafting on the rapids rivers. Easily damaged by sharp objects in the water or on the shore.
2. Boat of modern materials (PVC, polyester, etc.), Stronger than rubber. She is not afraid of rocky shore, driftwood and thresholds. The design of such plavstredstv a lot of improvements that are not available rubber. Of several of the same type of rubber and PVC ships constructed a raft of increased size.
By means of additional inflatable parts on straight sides, in the fore or aft dimensions vary. Covering such boats do not spoil the sun's rays, gasoline and oil. The pressure in the cylinders as compared with a rubber boat above.
3. inflatable catamaran - a viable option for the company, transportation equipment, food, and things travel. However, it is problematic to pass through the narrow stretch of the river.
For catamarans characterized unclosed bead when cylinders called floats parallel to each other at a distance. At the same time they are connected to a rigid platform or flexible bottom, padded rigid deck.
For boats catamaran type are those in which both are attached along the length of the float and connected by a flexible bottom. They bow and stern of the bottom folded up to form visors. The catamaran is sometimes converted inflatable canoes. To do this, they are held together across the rigid structures.
Fans comfortable and unhurried alloy on calm river connected catamarans, yielding alloy raft. Achieve the same effect, fixing between the catamaran floats more inflatable balloons.
Catamaran unsurpassed in stability and load capacity. At the same time it is not necessary to overload. It is easier to manage and add comfort.
4. Among the most versatile splavochnyh pertains inflatable kayak. It is suitable to fuse pair. They differ in design, performance and easy handling. However, they require trained paddlers due to the ability to easily roll over.
Justify themselves on the rivers with strong currents and the alloy in the mountains. The housing have an elongated cusp and on both sides. Suitable for short trips and sports on the water.
They use several cylinders on each side. This is done for stability and reliability. At the same time it won Useful area and increased cockpit freeboard.
Canoeing passes livelier than in other types of boats, which requires precise organization and discipline
5. Rafts - boats in the form of inflatable raftsSuitable for beginners alloy groups under the guidance of the instructor. Stability and reliability of the raft helps pass turbulent rivers and rapids. Its main purpose - rafting on mountain rivers.
He that has become a classic, oval body shape, bow and stern are raised. Together with the boards they prevent water flooding the crew. Inflatable cans, benches prishnurovyvayutsya to the board or pasted into them. For attaching luggage or fixing leg rowers arranged durable hinges.
Plastic protector protects the board when hitting the rocks. On the exterior sides of a rail arranged durable cable, which is transferred via raft. they also need to keep people overboard.
In the alloy needed awning over his head against the scorching sun and rain. If the completeness of the product does not provide a waterproof bag for the right things in the journey, she should get. Be sure to need a corresponding kit for repairing the damages and reserve foot pump.
It is important to thoroughly check the integrity of the cylinders with air. This procedure is to prevent possible trouble during the rafting.
The disadvantages carry worse than the boats with rigid body handling, comfort and low speed.
Exploitation
Model, floating through the air pumped into the cylinders, require attention during the operation. It is primarily concerned with approach and departure. Haste and carelessness when making these maneuvers resulting in damage to the inflatable shell stones, glass splinters, sharp fragments of branches and snags.
Therefore, approaching the shore, and waste must be moving against the tide, using the calm backwaters. If a strong wind and waves is done only in shallow water when the shore is covered with sand or pebbles. In such situations, they move slowly, looking intently into the water. In the same way it is better to swim in unfamiliar and littered with branches sticking out ponds.
We inflatable boats and small draft chassis having sail. At the same time a strong wind blowing from the shore, catches a wave. This creates problems in the management of which is better to put the bow or stern to the waves. By the rivers of wave height does not exceed half a meter, but there are cases where during the spring flood over one meter.
In such circumstances, smarter - to stay at the beach or ride out the bad weather on the beach. Avoid swimming in the dark or in fog near the fairway. If circumstances force to do so, use the signal flashlight and carefully listen to the sounds of water. This will avoid collisions with other vessels.
Attention should be paid to the behavior of the boat. We should not allow the bank. Change places only near the shore. It is necessary to move in slowly, being closer to the center. Moving from one boat to another, without any sudden movements.
It is unacceptable to jump out of the boat to the shore or dock, until it stops. Otherwise there is a risk of falling into the water as a result of repulsion of the ship during a jump.
To prevent trouble during the rafting preventive measures are taken. You can not hit the road without a set of materials and tools for repairing the damages of the inflatable body:
- pieces of the material from which made the boat
- adhesive suitable material unexpired expiration date and instructions on the use of
- knife and scissors
- a roll of tape firmly adhere
- a couple of dozen meters durable adhesive tape
- sandpaper to handle the bonding surfaces
In addition, it is necessary to stock a sufficient number of durable and lightweight tether.
You should carefully check the technical condition and completeness of the selected water transport, oars. It is mandatory to ensure that team members lifejackets of appropriate size.
