The motor boat "Progress 4" was launched back in the middle of the last century. During this time, she established herself as a fairly reliable and durable vehicle. This is evidenced by its technical characteristics. "Progress 4" is used in coastal waters with little excitement. This is a good tourist boat for families. Fishermen were also able to appreciate all the advantages of "Progress 4", which imply its technical characteristics. Knowing them, you can not only properly operate the boat, but also modify it as required. Then this vehicle will become the most convenient for its owner.
Application area
The motor boat Progress 4 was developed in the 1960s at the Kuibyshev aircraft plant. Specifications distinguish it from the entire series. This is a very successful model.
It can safely go to the coastal waters of rivers and seas up to 3 km, even with a wavelength of 0.75 m. This is completely possible to do the technical specifications. "Progress 4" in such conditions will slightly reduce the speed, because the waves will beat on the bottom.
The boat has a good carrying capacity and sufficient dimensions, which make it suitable for long tourist trips for a maximum of 3 people.
For short family walks, it can be used for a team of 4-5 people. You can travel by boat at any time of the day.
The presence of many thoughtful details makes sailing on a boat "Progress 4" comfortable. Specifications allow her to develop decent speed.
General form
The hull of the Progress 4 motor boat is made of duralumin alloys, which makes its technical characteristics suitable for good workload. The design is riveted and has outstanding planing contours.
In the bow of the open space there is a luggage compartment with a hatch. In the stern is located the engine compartment. It contains two 20-liter fuel tanks. Tools and spare parts are also stored here.
The technical characteristics of the Progress 4 transom allow you to drain water remotely through a valve.
Delivery involves the presence of soft volumetric pillows on the seats, a folding tent, windshields, wipers and steering gear. It is possible to control remotely defined Progress 4 boat systems. Its technical characteristics suggest such actions for gas, reverse of the Whirlwind outboard motor, and also running lights.
Options
The thickness of the bottom sheathing is about 2 mm, and the sides on the deck reach 1.5 mm. The longest length is 4.69 m, the width reaches 1.72 m. The height of the "Progress 4" sides is characterized by a size of 0.69 m; this suggests a load capacity of 475 kg.
The pitching angle of the bottom is 7 degrees. The mass of the case is 180 kg model "Progress 4". Technical characteristics of the weight of the boat are considered in the load mode. With a full set of equipment, it is about 283 kg. That is, on board, in addition to the main gear, it is possible to accommodate a weight of 192 kg, which is stipulated by the technical characteristics and dimensions of the "Progress 4".
Unsinkability is ensured by airtight compartments on the bow and stern. The technical characteristics of the Progress 4 boat include storage in the transom of the engine when it is on shore.
Equipment
There are two types of boat equipment. 1U assumes the presence of a soft awning, and 2U - a removable metal cabin of a collapsible type. This difference slightly affects the parameters of the motor "Progress 4", technical specifications. The plans, the size of which is determined by the parameters of the bottom of the boat, are included in any delivery package. Their dimensions are equal: 2.56 m - length, 1.44 m - width, plywood thickness - 6 mm. If the wheelhouse is rigid, its size occupies most of the cockpit.
According to the plan, the dimensions of the cutting itself are 1.8 x 1.3 m. Its weight is 30 kg. A hatch is provided for the driver in the hardwood cover.
Speed
As a standard, the Progress 4 motor boat, the technical characteristics of which can accommodate a maximum of 5 people on board, is equipped with a Whirlwind-M motor. At full load, it allows you to reach a speed of 22 km / h. The engine propeller has a standard diameter of 240 mm (D), and the pitch of the blades is 300 mm (N).
With an unloaded boat, the Whirlwind-M will reach a maximum speed of 37 km / h.
Sometimes, in order to increase speed, users replace the motor with a Whirlwind-30. At the same time, the speed of the boat will be from 32 to 40 km / h, depending on the availability of luggage.
For the cargo type “Whirlwind-M” of the motor boat “Progress 4”, the technical characteristics and dimensions of the propeller should be: D = 240 mm, N = 240 mm, then the speed will be 33-34 km / h.
The Vortex-30 engine should optimally have a screw D = 240 mm, N = 282 mm. Its speed at the time of full load then increases to 39.5 km / h.
If there are two 25 liter engines on a motor boat. from. power, it can reach a speed of 52 km / h.
Homemade cabin
The cabin on a motor boat performs protective and aesthetic functions. It will allow you to use the vehicle in the cold season.
Due to limited resources or the desire to complete the most suitable design, many resort to an independent arrangement of logging, which has a boat "Progress 4". Specifications require that this element does not increase windage and weight, does not limit the steering view, and does not affect stability. Chopping should not greatly reduce cockpit space. It is also important that this home-made element does not impair the aesthetic appearance of the boat.
To comply with these requirements, a number of recommendations should be considered. The height of the homemade cabin should have minimal performance, but at the same time allow the highest crew member to move under it.
The boat "Progress 4", the technical characteristics of which require maintaining the correct center of gravity, should have the highest felling point as far as possible from the bow.
Vertical walls and bent silhouettes should also be avoided. The cabin should occupy no more space than the cockpit itself.
Awning
If necessary, replace the awning, you can do it yourself. It will turn out, perhaps even better than the purchase option. To do this, it must be protected from the weather and the scorching sun, easily fold up and stand above the boat, and also be reliable. This requires technical specifications. "Progress 4" must have an awning resistant to weathering. To do this, it must be made of dense material and have a strong frame.
A boat awning should not prevent the team from moving around the deck, as well as placing things. Moreover, this applies to both its expanded and collapsed position.
If the windows and sidewalls are made of solid materials, they should be hinged so as not to increase the volume of the structure.
Transom
Another important part of a motor boat is its transom. It happens that it needs to be strengthened. This will increase the reliability of the motor design "Progress 4". The transom specifications are described in earlier models as a rather unreliable element. In later copies, this detail was reinforced with knights.
You can independently strengthen the transom with hairpins. They are screwed into the cockpit bulkhead and locked with nuts on all sides. They should not be screeds or struts. Studs should not interfere with turning, folding the motor.
If the transom is in a fairly good condition, it can be strengthened by making a bunch with the bottom or side. In this case, the board should be made new. A base is made of a 28 mm thick board and glued with plywood on both sides.
Hydrofoil
The hydrofoils lift the Progress 4 boat above the water. Technical characteristics allow them to increase the speed of the vehicle.
This element can be fully or partially immersed in water. It is controlled by flaps (angle of attack). A ship with partial hydrofoil partial immersion is considered more stable.
There are a number of difficulties that should be considered when applying this element. Hydrofoils reduce its stability. Motorbike "Progress 4", the technical characteristics of which take into account the presence of hydrofoils, should provide for the correct placement of luggage and crew.
The outboard motor must have a speed margin so that with an increase in speed it does not exceed their permissible number. A lower screw fit is also required.
Sail
It is allowed to install a direct sail on the boat. He will let him walk under the wind. For its manufacture, light but strong fabric is used. Better if it is synthetics.
Stock angles are reinforced by pads. Metal rings are sewn into them. To exclude an unauthorized turn, braces and sheets are bred separately for the front and rear racks.
Maximum sail should be rotated no more than 35-40 degrees on each side.
The sail should be durable, waterproof, windproof and light. The weight of the entire structure should be in the range of 5-15 kg. The boat is usually not equipped with a sail. With a great desire, you can do it yourself.
You can correctly apply the presented vehicle, having considered all its technical characteristics. "Progress 4" is the best model among similar products of the manufacturer. Following all the recommendations, it will be easy to finalize the design and make the use of the boat even more comfortable and reliable. Knowing its parameters will allow you to travel safely over fairly large distances at any time of the day or year. Adhering to the requirements for the operation of this vehicle, there is no doubt that traveling with your family or fishing will be pleasant and leave a lot of unforgettable positive impressions about yourself.
