The Yuzhanka series aluminum mottles are well-deservedly considered classics of domestic boating sports and amateur fishing. These vessels, developed in the Soviet period at the Nikolaev Shipyard, still ply the expanses of rivers and lakes, attracting attention with their reliability and time-tested design. However, when buying a used copy or ordering a new hull from private craftsmen copying the original, it is critical to know exactly what to do. geometrical products.
Understanding the real dimensions is necessary not only for assessing the capacity and seaworthiness, but also for the correct selection. boat-engineMiscalculations of length or width can lead to a problem with GIMS registration if the actual dimensions are very different from the stated ones. In this article, we will examine in detail all the nuances of the dimensions of the various modifications of this legendary boat.
It's worth noting that over the years, the design has undergone changes, and many private shipyards continue to produce copies with slight deviations from the factory drawings. nominal length of 4.5 metres It's often a little bit more or less, depending on the year of manufacture and the manufacturer, so let's look at what those numbers are made of and what each inch of the case is affected by.
General overall specifications of the shell
The classic South Side is a gleaming vessel with sharp-bumped contours, which ensures it has excellent wave germination and good handling. The main parameter determining the class of the boat is its length along the constructive waterline and full length. For the base model, these indicators are strictly regulated by technical conditions, although in practice there are slight variations.
The width of the mid-spangout body is the second key indicator that affects stability. The narrow body is easier to glid with low-power engines, but less stable in the parking lot. In the case of the South, engineers found a balance that provides comfort for 3-4 people. full-width This can differ from the width of the cheekbone, and when calculating space in the garage or on the trailer, this plays a crucial role.
The height of the cockpit is a parameter that is often overlooked by looking only at length and width. However, it is the height of the cockpit, combined with the shape of the forehead, that determines how often waves will overwhelm the cockpit. The Southern cockpit has enough height to navigate the reservoirs calmly, but on a large wavelength, caution is required. Below are the main dimensions in the comparative table.
| Parameter | Value (mm) | Note |
|---|---|---|
| Full length | 4500 | Maximum length for piku and transom |
| Full width | 1620 | Midel-spangout. |
| Height of board | 620 | Midle. |
| Hull mass | 145-155 | No equipment or motor. |
Detailed dimensions of modifications: M, M2, M3, M4
The evolution of the Southern model led to several modifications, each with its own design features that affect the dimensions. The base model of the Southern-M became the benchmark, but subsequent versions of the M2, M3 and M4 made adjustments to the geometry of the hull to improve driving performance and safety.
Modifications South M2. The design of the deck and bulkhead was changed, which had a slight effect on the internal volume of the cockpit, but the external dimensions remained almost identical to the original. South M3.The most modern version, the M4, often features a reinforced transom under more powerful motors, which adds a few kilograms of weight but does not change the length significantly.
- 🚤 South-M: Classic version, length 4.5 m, width 1.62 m, transom for an outboard motor up to 30 hp.
- 🚤 South-M2: Improved deck, body dimensions are similar to the base model, improved ergonomics.
- 🚤 South M3: The geometry of the stern has been changed, a slight difference in the length of the lower unit engine is possible.
When choosing between modifications, you should pay attention not only to data-sheet figures, but also to real measurements, especially if the boat was manufactured long ago. Metal has the ability to deform when hitting logs or stones, which can change the geometry of the transom and, as a result, the position of the motor relative to the bottom.
When buying a used boat, always bring a roulette with you. A difference of 5-10 cm can be critical for installation in a narrow garage or on a specific trailer.
Transnant dimensions and motor requirements
transom is the heart of any motobodock, which determines its speed potential. For the Southpanka, the transom dimensions are strictly standardized to match the lower units of common domestic engines, Whirlwind and Neptune, as well as imported ones. The height of the transom is a critical parameter: too low will lead to splashing and loss of power, too high – to cavitation and overheating of the engine.
The standard transom height for the Southerner is 380 mm (15 inches), which corresponds to a short lower unit. However, many owners, when repairing or tuning, increase the transom to install more powerful motors with a long leg (20 inches or 508 mm). stern height This increases, which is important to consider when calculating the alignment of the boat, and moving the engine backwards without changing the internal bulkheads can lead to differentiation at the stern.
⚠️ Attention: Installation of the motor with a capacity of more than 30 hp on the standard "Southern" without strengthening the transom and reworking the body is prohibited by safety rules and can lead to the destruction of aluminum seams.
The width of the transom is also important for the installation of twin-engine coupling or attachments like downrigers. Standard width allows you to confidently fasten the engines to 30-35 hp When installing heavier engines, you may need to expand the transom plate, which formally changes the classification of the vessel.
How to measure the height of the transom?
Measurement shall be made from the upper plane of the transom board to the conditional line of the continuation of the bottom (keel line), and not to the lowest point of the shell if the bottom is complex.
Internal dimensions of the cockpit and usable area
The outer dimensions of the boat are only half the information. For the fisherman or tourist, it is much more important how much space remains inside after the installation of cans (seats), runduks and fuel tanks. The Southerners cockpit is designed rationally, but its useful area depends on the size of the deck superstructure and the zygomatic splashers.
The length of the cockpit from the forepeak to the transom allows three adults to comfortably accommodate, although officially the boat is often registered as a 4-seater. The width at the level of the cans (seats) provides enough space for the legs, but the placement of large equipment, such as large fishing boxes or tents, requires careful planning. Useful area The floor is also reduced by the zygomatic stringers that run along the sides inside the boat.
- 🎣 Cockpit length: About 3.2 - 3.4 meters of usable space.
- 🎣 The width at the can level: Approximately 1.3 - 1.4 metres between the sides.
- 🎣 Height below deck: It allows you to place small things, but is not designed for large loads.
It's important to consider the height of the superstructure (if any) or the distance from the bank to the top of the board, which affects the ability to install an awning or a running bridge. fiberglasswhich may reduce the useful width of the passageway in the central part of the boat.
☑️ Internal volume audit
Boat weight and impact on load capacity
The weight of the hull is one of the most discussed parameters, as it directly affects the required power of the engine and the ability to transport a boat on the roof of a car or a light trailer. The factory "Southern" weighs about 145-150 kg, but this figure is strongly dependent on the thickness of the aluminum alloy used and the amount of equipment installed.
Homemade replicas or boats that have undergone major overhauls with the replacement of bottom sheets with thicker ones can weigh up to 180-200 kg. This is a significant difference that reduces the payload. If the rated carrying capacity is 400 kg, then if you increase the weight of the hull by 30 kg, you lose the ability to carry one passenger or a significant supply of fuel and equipment. Specific gravity Aluminum allows you to create lightweight structures, but saving on material in favor of weight loss is unacceptable.
⚠️ Warning: Exceeding the rated carrying capacity even by 10-15% sharply reduces the height of the board above the water, making the boat vulnerable to flooding with the slightest heel.
When calculating weight, remember to add a lot of permanent equipment: anchors, safety end, fixed tanks and batteries, all of which eat up a useful margin of buoyancy. To accurately determine the weight of a particular boat, it is better to use a scale, since visual assessment is often mistaken.
The optimal weight of the "Southern" for the engine 15-20 hp should not exceed 160 kg together with all stationary equipment.
Transportation and storage: dimensions in context
When planning to buy the South, you need to evaluate the storage and transportation possibilities in advance. The length of 4.5 meters allows you to transport a boat on a standard car trailer, but requires compliance with the rules of overhang. If you plan to transport on the roof of a passenger car, the weight of 150 kg will be a serious obstacle, requiring the use of a winch and the help of several people.
The width of the boat 1.62 meters perfectly fits into the dimensions of the roadway when transported by trailer, without requiring special permits for oversized cargo. However, the height of the boat, together with the trailer and the engine (if it is not removed), can exceed 2.5 meters, which limits travel under some bridges and low garage gates. Removable engine The dismantled elements (console, banks) greatly simplify logistics.
For storage in winter, it is important to consider not only the length and width, but also the need for access for maintenance. The boat must be put on keel blocks or suspended, which requires appropriate space in height in the garage or shed. Aluminum is not afraid of frost, but proper storage will prolong the life of seals and wooden elements.
- 🚛 Trailer length: It should be at least 5 meters, taking into account the breath.
- 🚛 Gate height: At least 2.2 meters for a trailer.
- 🚛 Car load capacity: Check the possibility of towing a trailer with a boat (about 250-300 kg in the collection).
What is the real length of the boat South, taking into account the bow and stern extremities?
The full length is exactly 4500 mm (4.5 meters). However, when measuring for a trailer, a margin is often added to the kilblocks and overhang of the engine, which increases the required length of the pad to 4.8-5.0 meters.
Can I increase the width of the South with self-building?
Theoretically, you can change the pattern of the frames, but it will violate the design stability and driving performance. The factory width of 1620 mm is optimal for this type of contours.
Does the installation of inflatable tubes affect the dimensions of the boat?
Yes, the installation of inflatable tubes (liquors) increases the total width of the boat by 20-30 cm from each side and the height of the board, which changes the sailing and dimensions during transportation.
How much weight does a standard Southern Tran bear?
The standard transom is designed for a motor weighing up to 50-60 kg (up to about 30 hp). Exceeding this weight requires mandatory strengthening of the transom board and zygomatic stringers.
