Metal crafts of the Soviet and post-Soviet era still occupy a significant share of the market, and among them occupies a special place. Progress 4This model has become a kind of safety standard for fishermen and hunters, who care less about speed than about sustainability and safety on the water. size This boat is critically important not only when buying, but also when planning transportation, choosing a place for storage and selecting the appropriate storage. boat-engine.
Owners often face the need to know the width and height of the side to calculate the possibility of transporting on the roof of a passenger car or a standard trailer. Progress 4 It differs from its predecessors in increased passenger capacity and modified geometry of the hull, which makes it more comfortable, but also more demanding towing conditions. In this article, we will discuss in detail all the dimensions, weight specifications and nuances of operation that every potential or current owner should know.
Understanding the real data, not just the data-sheet figures, will help avoid unpleasant surprises when launching or loading equipment. cockpit And we're going to explore the convenience of fishing, and why transom height is a key parameter for engine power, and let's dive into the technical details that define the performance of this legendary boat.
General overall dimensions of the shell
The basis for any calculations is the total length of the body, which the model has. Progress 4 This value is standard for four-seater metal boats of the period and provides good germination on the wave, but significantly affects maneuverability in narrow ducts. The length of the waterline at full load is usually smaller and is about 3800 mm, which is important to consider when calculating the theoretical speed of the stroke.
The width of the body on the middle spangout is 1500 mm, which is key indicator of stability This width allows even three adult passengers to feel confident on the water, spreading the weight evenly, but it also dictates the width of the roadway when transported on a trailer. Narrow roads or bushed entrances to the water can be a serious obstacle to wide boarding.
The height of the midfield is 530 mm, which, in combination with the forehead, provides good protection against splashing and scooping of water when moving against the wave. However, it is worth remembering that the actual height of the board above the water depends on the load, and with a full crew. float-stock It decreases, requiring increased caution.
- 📏 Total length of the body: exactly 4000 mm
- 📐 Midwidth: 1500 mm
- 🌊 Height of board: 530 mm
- 🛶 Waterline length: 3800 mm
Dimensions Progress 4 They make it a versatile tool for medium-sized water bodies that require a combination of capacity and cross-country, but the owner should be aware that a width of 1.5 meters may not allow a boat to drag through some bottlenecks without the use of special wheelchairs.
Weight specifications and load capacity
The weight of the boat in running order without the engine and equipment is about 145-150 kg. This is a rather heavy boat, which is almost impossible to unload on shore by hand without the use of a winch or slip. Hull mass
Passenger capacity Progress 4 It's 400 kg, which is technically enough to accommodate four medium-sized people, but in practice, given the weight of the hull itself, the buoyancy margin may not be enough in a critical situation. safe-loading It is often limited to three passengers and a minimum set of equipment.
⚠️ Attention: The actual load capacity may be reduced due to metal corrosion and moisture accumulation in the halduks, so you should not load the boat to the limit values specified in the data sheet.
The distribution of weight inside the cockpit also plays an important role: shifting the load to one of the sides can lead to a dangerous roll, given the relatively flat contours of the bottom. Heavy objects such as batteries and anchors should be placed strictly on the diametric plane and as low as possible.
Transcent sizes and motor requirements
Train boat Progress 4 It has a standard suspension height of 355 mm (14 inches) for Soviet models, which corresponds to the standard in force at the time. boat-engine Often have a different geometry of the lower unit, so when installing a new engine may require the manufacture of a stretcher or modification of the transax board.
The transomper is about 360-380 mm wide, which allows the engine to be installed with a power of up to 15-20 hp without the risk of overloading the aft. Exceeding the recommended power can lead to splashing of the cockpit and even to tipping the boat in a sharp maneuver, since centre-up It's moving too far back.
- 🚤 Transnant height: 355 mm (standard 14)
- ⚙️ Maximum engine power: up to 20 hp
- 🔩 Recommended power: 8-12 hp
- 🛡️ Transboard material: duraluminium
When installing the engine, it is important to take into account not only its power, but also its weight, since heavy two-stroke engines of older models can significantly change the trim. Progress 4 It is best behaves with engines in the range of 8-12 hp, providing an optimal balance between speed and efficiency.
When installing a modern four-stroke engine, check the height of the anti-cavitation plate relative to the bottom - it should be parallel to the bottom plane or slightly raised for better germination on the wave.
Internal layout and size of the cockpit
The interior space of the boat is organized with the accommodation of four people, but free space for the legs and gear is limited. The length of the useful part of the cockpit is approximately 2500-2700 mm, which allows you to comfortably accommodate two fishermen with fishing rods or three passengers in a dense layout.
The height of the seats (cans) above the bottom varies, but is usually about 300 mm, which ensures an acceptable fit. jock-stuffThey are not only used for storage, but also provide additional buoyancy in the event of a rollover.
| Parameter | Meaning | Comments |
|---|---|---|
| Cockpit length | ~2600 mm | Useful space |
| Cockpit width | ~1300 mm | Inner width |
| Boat height inside | ~450 mm | From sleigh to timber |
| Volume of rundooks | ~40 l | Total volume |
The presence of slats (wooden or metal grilles on the bottom) is an indispensable element of comfort, since the metal bottom Progress 4 It cools down quickly and can be slippery. The proper organization of the interior space allows you to place anchors, life jackets and fishing boxes without cluttering the passageway.
Transport and storage
Transportation Progress 4 On the roof of a passenger car, it is possible only if there are powerful crossbars and traffic rules regarding dimensions. The width of the boat is 1500 mm plus crossbar overhangs can exceed the standard width of the car, which requires the installation of additional signal lights and signs. bulk-load.
The more common way is to transport on a trailer, where the boat is mounted with a keel on a paddle or roller, while it is important to consider the total height of the train (car + trailer + boat), which can reach 2.5-2.7 meters, which limits travel under some bridges or power lines.
☑️ Preparation for transport
Keeping the boat outdoors is not recommended due to the risk of accumulation of precipitation inside the hull, which can lead to corrosion and collapse of the structure. The ideal option is a canopy or garage where metal-frame It will be protected from direct sunlight and precipitation.
⚠️ Warning: When stored on a trailer in winter, be sure to remove the transom plug and leave the boat open or nose-up to prevent the water from freezing inside.
Comparison with analogues and modifications
In his class. Progress 4 It competes with models such as the Kazanka-M or Ob-3, with a number of advantages in terms of greater width and height, but it often loses weight to more modern aluminum counterparts, making it less attractive to owners of small cars without powerful trailers.
There are various modifications and tuning versions of this boat, including the installation of soft seats, tent covers and even small cabins. sailability and the center of gravity, which must be taken into account when operating in windy weather.
Many owners are making self-refurbishments, replacing regular cans with more comfortable seats with backrests and installing additional storage drawers, which make the boat more comfortable for long walks, but require careful weighting of the structures installed.
History of the model
The Progress 4 boat was produced in the late 1960s and became a development of the Progress 2 model. The main difference was the increased width and changed shape of the bow, which allowed to improve seaworthiness.
Progress 4 remains a viable choice for medium-sized fishing due to its combination of low cost, reliability and ease of maintenance, despite its age.
Frequently Asked Questions (FAQ)
What is the maximum weight of the engine to be put on Progress 4?
Optimal is considered to be a motor weighing up to 40-45 kg. Heavy motors can overload the transom and disrupt differentiation, although the transom can withstand high loads when installed correctly.
Do I need to register the Progress 4 boat in GIMS?
Yes, if the weight of the curbed boat with the installed engine exceeds 200 kg. Since the weight of the Progress 4 itself is about 150 kg, the addition of any motor weighing more than 50 kg will require mandatory registration.
Can I sew up the nose of a boat with plywood to increase the volume?
Theoretically, it can, but it will change the centering and buoyancy. The forepeak can create an unsinkable compartment, but it requires a competent engineering approach to not disturb the stability.
What is the speed of the 10 HP engine?
With a motor of 10 hp. and one passenger speed can reach 20-22 km / h When fully loaded, the speed will drop to 15-17 km / h, which is normal for boats of such displacement.
