Tuning boat Kazanka 2M

Flaws

• The only drawback of this vessel is severe electrochemical corrosion of the hull
• The matter is aggravated by steel linings at the seam joints
• When encountering a passing wave, yaw characteristic of ships of similar structure appears. But there is no danger of going overkill

History and goals of creation

A boat called Kazanka 2M was released to replace the old version. Their design is almost completely identical, since development engineers have been working for several years to study the shortcomings of the predecessor and eliminate them in the new modification.

The motorboat remains in memory as the largest of all produced by the domestic industry. The creation process lasted from 1968 to 1971. A year later it was presented to the public and appeared on store shelves. Almost simultaneously with it, the plant began production of the next model, so production of the old one was not long enough to saturate the market and soon ceased. This is what makes this version so valuable.

Technical characteristics of the boat "Kazanka-6"

The Kazanka-6 and Kazanka-6M boats are fundamentally different from all the models described above. They are as simple and spacious as possible. They can fit up to three people, which is equivalent to three hundred kilograms. The boats are characterized by the lowest possible draft, but can only be used in relatively calm weather. As a rule, they are used for transportation on small lakes and rivers. The dry weight of such boats is very small - up to hundreds of kilograms. In most cases they are used for rowing. The boats are characterized by maximum ease of use and high anti-corrosion properties.

The main characteristics are similar to Kazanka 2 and reflect good seaworthiness and significant capacity of the motorboat.

Advantages of the boat

Having brought the boat from the store, the partners discovered on its nameplate the characteristic: “boat weight - 220 kg.”
Knowing that the reference book for the Kazanka-2M gave a weight value of 250 kg. (see above), the buyers were very happy about this circumstance. Later, on occasion, weighing the boat, they were convinced that the boat really weighed 220 kg with all the passport equipment. At first, “Kazanka-2M” was operated under “Vikhrem-M” and “Veterok-8”, which were “inherited” from inflatable boats and rafts. Thanks to the “twisted” contours and the large L/B aspect ratio, the total power of these two engines is 33 hp. it was enough for planing a boat with 4 people. crew and equipment for the weekend. Subsequently, a second Vikhr-M was purchased for this boat, after which the problems with going on plane with a full crew and maximum load disappeared.

Thanks to its sharp bow contours and high L/B ratio, the Kazanka-2M was distinguished by its smooth ride in rough seas. Of course, when traveling at a speed of more than 40 km/h, when the impacts fell on the aft, flatter part of the bottom, the force of the impacts increased significantly. But by reducing the speed to 30 km/h it was possible to calmly go against 1.5-meter waves. The “swirled” contours reflected the spray well downwards, and the cockpit practically did not flood. When sailing along a following and following side wave, the yaw characteristic of ships with such contours manifested itself, however, due to the large dimensions of the Kazanka-2M and the slightly higher deadrise of the bottom in the stern compared to the same Kazanka-5, the yaw was unpleasant, but not dangerous. In general, the Kazanka-2M was significantly more seaworthy than the then widespread Progress, Krymov and Obey.

The strength of the case was not satisfactory. Despite repeated pulling of the boat onto the rocky shores of the islands, the bottom did not receive significant damage. Shock loads from sailing in rough seas also did not cause damage to the hull structures.

Disadvantages of the boat

The main disadvantage of the Kazanka-2M is severe electrochemical corrosion of the body. The fact is that the linings covering the joints of the skin sheets of the bottom halves and the bottom and sides were made of steel. As a result, the duralumin of the skin at the joint was subjected to severe corrosion. The body resisted corrosion for 5~6 years, after which, due to inevitable damage to the paintwork, corrosion took on a threatening appearance. The owner of the boat was forced to devote considerable time to repair work, gradually replacing steel parts with aluminum ones. To this day, the described “Kazanka-2M” is in working order, but there were years when the owner could not go sailing due to the large amount of repair work.

Another disadvantage is the installation of motors on a remote bracket. Due to this installation method, the engines were filled with water during rough seas, which led to failures of the ignition system. In addition, due to the excessive height of the upper edge of the sub-motor board of the bracket, the screws “grabbed air” during the wave. After going through four seasons with the bracket, the owner of the Kazanka-2M remade the transom similarly to the Oka-4 transom; the bottom of the recess was made wide and flat and housed two Vikhrevsky tanks.

Characteristics of the motor boat "Kazanka-2M"

"Kazanka-2M" was the largest and most capacious of those produced by the domestic industry until 1977. motorboat (currently out of production). The boat's riveted duralumin hull has sharp-chine planing contours with a "twisted" bottom - with a strongly varying deadrise from stem to transom. Thanks to the increased length and low deadrise of the bottom in the aft part, the vessel has good performance even with one 22 kW motor. With a standard propeller on the Vikhr-30 engine, the Kazanka-2M boat reached a test speed of 26.7 km/h with six and 38.3 km/h with two passengers on board.

The transverse set of the Kazanka-2M hull consists of 10 frames; Low corrugations are stamped on the bottom, sides and deck to increase the rigidity of the thin skin. The tightness of rivet seams is ensured using sealants and putty. The sealed forepeak and storage box located in the cockpit under the two aft seats, with a total volume of about 380 liters, ensure the motor boat is unsinkable. There are two closed trunks - the bow for storing camping equipment and the stern for fuel tanks. When parked, the outboard motor may be locked in the stern trunk.

Appearance and design features

The technical characteristics of the 2M Kazanka remain the same. The riveted hull was manufactured from D 16. Unlike marine hulls of the monohedron type, the special shape of the bottom with a deadrise from the stem to the transom line, varying in the range from 7 to 17 degrees, easily goes into planing with 4 passengers and the necessary equipment. All surfaces and seams on the bottom, sides and deck are anodized, primed and covered with waterproof paint.

The designers left in the modification of the Yuzhanka many places for storing equipment in the cockpit. The motors located on a bracket behind the transom, placed forward, ensure the seaworthiness of the model. For this reason, the height of the side in the stern became greater, which eliminated the problem of flooding the rear part of the vessel with water and reducing speed.

Motor boat Kazanka-5, Kazanka-5M

Characteristics of motorboats "Kazanka-5" and "Kazanka-5M"

The Kazanka-5 motorboat was produced by the aircraft plant named after. S.P. Gorbunova for 6 years, starting in 1972. The vessel was designed with the expectation of increased seaworthiness and comfort with the limited power of outboard motors produced by the domestic industry. To provide planing capability with one 25~30 HP motor. The contours of the hull are adopted with a relatively low deadrise of the bottom at the transom and with a strong sharpening of the bow tip. The consequence of this is good driving performance and low trim when sailing with a full load. When sailing in rough water, however, the boat, crashing into the wave, skids dangerously. The small running trim causes an increased wetted length of the hull, so the maximum speed of the Kazanka-5 is somewhat lower than that of other boats of similar dimensions.

Operation of a motor boat is allowed at a distance from the shore of up to 3 km at a wave height of up to 0.75 m. On the Kazanka-5 model, the installation of one motor with a power of no more than 30 hp is allowed.
