Yaroslavets- the name of a series of service and auxiliary boats.

By 1948, at the SME design bureau, a design for a multi-purpose boat for the needs of the Navy and the national economy was developed and approved. The basis was taken on the “Ya” type boat produced in the 1930-1940s. The project received the number 376 and the code “North”. In 1953, the lead boat of the project was launched at shipyard No. 345. The boats of the project received their name - “Yaroslavets” after the name of the enterprise. The second enterprise where the production of boats began was Sosnovsky Shipyard No. 640 in the Kirov region. Small series of boats were built at the plant in Russa, Novgorod region and at the Krasnoyarsk ship repair and shipbuilding plant, at the Leninskaya Kuznitsa plant and shipyards in Varna in Bulgaria.

Boat modifications

The initial project envisaged the development of three modifications of the boat: a work boat, a customs boat and a diving boat, which could be transported by rail.

Based on the project, the following modifications were developed:

• Raid boat, radiation and chemical reconnaissance boat, ambulance boat - 376;
• Travel work boat - P376; R376U; RN376U
• Modernized raid work boat (tug boat) - RM376;
• Training boat - RMU376;
• Marine hydrographic surveying boat - G376;
• Large hydrographic boat of the "GPB-511" type - G376U;
• Raid diving boat - RV376, RV376U
• Raid diving boat with a decompression chamber - RVK376;
• Passenger boat and for the needs of the National Economy - RVN376U;
• Modernized diving boat - RVM376 (03766);
• Raid diving boat - RVM376U;
• Minesweeper boat for contact and non-contact mines (road minesweeper) - T376;
• Boat minesweeper model 1957 - T376U
• Torpedo boat - L376M;
• Torpedo boat model 1962 - L376;
• Torpedo boat model 1954 - TL376;

• Large patrol boat - RV376, RV376A;
• Medium customs vessel - RVK376
• Mortar boat - M376
• PSKA for the Sea of ​​Azov - P376 (03765)

Modernization

A further development of the project is the project 02220 multi-purpose boat “Yaroslavets-M”. The boat was designed as a multi-purpose boat - patrol, service and pleasure, for transporting various cargoes, towing small vessels, or a support boat. The comfort and habitability of the boat were improved, and an additional bathroom and shower for the crew were installed. The lead boat (serial number 061) of the modernized project was launched at Yaroslavl Shipyard OJSC on June 25, 2015. Main characteristics of the vessel

Project R376, R376U, RM-376, RVM-376 type "Yaroslavets"
Vessels of the "Yaroslavets" type of project R-376, R-376U, RM-376, RVM-376 were built in a large series over several decades (1953 - 80) at different enterprises, in the versions of towing, crew, diving and other vessels. Author of the project: KB SME.
R-376, R-376U- Single-screw tug with a saddle deck, wheelhouse and superstructure on deck, with a hood over the main vessel and an aft cargo hold. Purpose - towing small ships, transporting 10-15 tons of cargo in holds, transporting up to 12 passengers. The boat can be transported by rail with the superstructure removed from the deck. (Handbook of serial transport vessels, volume 3, pp. 179-181 OPEN) project R376 project R376U In 1948, at the SME design bureau, the project was approved tugboat for the needs of the Navy and the national economy. The project was assigned the number 376 and the code “North”. The project provided development of documentation for the construction of three modifications of the boat at once: working, customs and diving. One of the indispensable design conditions put forward by the customer was the possibility of transporting the boat by rail. In 1953, at Shipyard No. 345 (now Yaroslavl Shipyard)the lead boat of Project 376 was launched. It was from the name of the lead boat enterprise, the project and received a semi-official name - “Yaroslavets” - instead of a code that was forgotten over time. Construction was immediately launched in a large series. The second large enterprise where Project 376 boats began to be built was Sosnovsky Shipyard, Shipyard No. 640. In 1955-57, an improved model of the boat was developed, designated 376u. Changes were made to the design of the boat to improve its technical and operational characteristics. A lot of effort was spent on working out manufacturability of production. The result was very successful for of its time, a project that was launched into mass production not only for the Navy, but also for civilian ministries and departments, as well as for supplies abroad. The type of vessel is a single-screw motor ship with a saddle deck, a pilothouse and a superstructure on the deck, with a hood above the main compartment and an aft hold. The boat hull is made entirely of welded transverse construction. It has 6 watertight bulkheads, 3 bottom fuel tanks. The dimensions of the hull are made with the condition that the boat can be transported by rail with the superstructure removed.The drawings below show the markings of the welded seams of the side plating and deck flooring, made from photographs of the boats. The width of the welds ranges from 4 to 10 mm. It should be noted that on many boats during repairs non-standard plating sheets or patches appear. As an example, see the explanation for the drawing of the Olympus boat. The design of the boat is adapted for sailing in shallow broken ice. This is due, among other things, to the presenceice Kingston, in whichwarm water is supplied to the external cooling circuit of the main engine,stem design,presence of ice reinforcement in the bowhousing in the form of a powerful T-beam. The power structure of the body uses a very powerful strip-bulbs are used as the basis for frames and beams; strips, angles, and plates are also used for the manufacture of stiffening ribs and other structural elements, and in the later series of Project 376U, many welded elements are replaced by bent profiles. The rudder on the boat is balanced and streamlined. Project 376 boats had only one rudder blade (Fig. 3, Fig. 6). The 376U has two rudder blades (Fig. 4, Fig. 5a). Accordingly, there are one or two plugs on the upper deck that cover the holes for installing the tiller. (The so-called “glasses” are screw plugs for the holes into which the tiller is inserted in order to control the boat manually if the drive steering cables suddenly break). Fig.3 Fig.4 Steering wheels are made hollow, welded from sheet metal (Fig. 5). The feather does not have a lower support and its loss is a common occurrence. For self-repairs, install a simpler pen - flat, made of a sheet of metal, with ribs (Fig. 5a). The feather is fastened with six bolts to a rectangular (on boats pr.376U - fig.5 and fig.5a) or round flange (on boats pr.376 - fig.6). Fig.5 Fig.5a rice. 6 There are 6 portholes on the left side of the boat. The porthole closest to the stern sometimes gets welded shut because... it is too close to the surface of the water. This usually happens during conversions, when a lot of ballast is added and the boat’s draft increases. There are only four portholes on the starboard side. Above the waterline there are three scuppers (pipe outlets for draining water from the deck). Between the first and second scuppers there is a pipe for the auxiliary engine cooling system. The fender beam running along the hull of the boat was made of both wood and metal. Apparently, factories initially made them from wood, and in the army and shipping companies, during repairs at factories, they were replaced with steel ones. Moreover, different designs were installed - 100 mm pipes, bent - “U”, “V” or “P”-shaped, as well as semicircular with a longitudinal edge (in the “E” section). Fig.7-8 Fenders were attached to the bow and stern of the hull. Currently they are generally not used. As fenders used as in the rest of the world - car tires. Fig.7 . Standard wooden beam. Visible are the fender mounting plates and rings, beam mounting brackets, and a steel strip along the beam. Fig.7 A.Standard wooden beam. The attached bow fender is visible. The superstructure on the upper deck is represented by the pilothouse and the engine room hood. There is a coaming along their lower part. The pilothouse of the boat is removable. This allows the boat to be transported by rail. It is attached to the coaming and the front of the burl using bolts. Project 376 and 376u boats have wheelhouses of various designs. Project 376 boats have a deckhouse made of smooth sheets with welded ribs inside. And Project 376u boats are made from sheets with vertical stampings. The cutting corners are rounded with radii of 100mm. It should be noted that sometimes there are boats that have the pilothouses from the Project 376u boat installed on the Project 376 hull (see photo “Zuyka”). There are three doors on the left side of the cabin and a rectangular window in the front of the cabin. Of these, the front door was located slightly higher. A welded footrest led to it from below. The middle door is sealed. It leads to the radio room. The door located closer to the stern (leading to the latrine) is splash-proof. These doors are equipped with portholes. There are two doors on the starboard side, a rectangular window in the front part of the cabin and two round portholes. On some boats, the windows in the wheelhouse are made to open - they slide down. The doors differed in design from each other. On Project 376 boats they had loops of a different design than on Project 376u boats. In total there are four series of doors. The earliest models featured simple hinges and handles on each of the latches. On sealed doors their number reached seven. Subsequently, a lever drive for the locks and one handle per side of the door were used. More reliable hinges were also introduced. On the latest doors, the central lock is made in the form of a spring latch. Fig.9-10.

A hook is attached to the rear wall of the cabin. There, on Project 376u boats, there was a ladder ladder leading to the navigation bridge (Fig. 11). On Project 376 boats, instead of ladder brackets, a removable ladder was installed, secured with bolts(Fig.1 2) . The handrails of the ladders are also different: inclined (on project 376u) or vertical (on project 376).

Fig. 11. Back wallsuperstructures pr.376U. The mast is down.	Fig.12 . Cap and superstructure of the Project 376 boat.

The cap on boats of all projects is not removable. It also varied somewhat among boats of different designs. Project 376 boats leaf at the top of the burl, as well as removable sheet above the MO (intended for dismantling the main and auxiliary engines and mechanisms), made of a flat sheet with stiffeners made of corners and strips welded to it, and for 376u - from profiledsheet without welded reinforcements(Fig. 1 3) . Some Project 376 boats do not have portholes on the removable burl sheet.

Towing bars were installed on the hood and in the rear of the hull. They are designed to prevent damage that could be caused by the tow rope during manoeuvres. On boats that are not used as towing boats, the stern towing bar is not is installed. In this case, the arc located on the MO cap, as a rule, is preserved. Arcs are made of several types. Cast, having a profile in the form of a channel, or tubular. In the aft part of the hood, in the center plane, there is a hinged hatch to the interior.(Fig. 14).

Deck hatches leading to the interior of the boat, like doors,Several types are used. Fig. 15-16. During production, the designs of hatches and doors, as well as other elements of the boat, were constantly improved towards improving the design, improving manufacturability and operational characteristics.

Inland water basins classified as “O” according to the classification of the Russian River Register.

Distinctive features

This motor ship has increased navigation safety compared to the motor ship P376 due to improved stability characteristics, and has a River Register class “O”, which allows operation in all river basins, including water bodies of the River Register class “M” (by additional order). The motor ship has greater autonomy, can be equipped with installations for treating wastewater and sub-sludge water, a fuel preparation unit that reduces fuel consumption by 10-15%. The layout of the motor ship and design documentation can be changed at the request of the customer.

Refurbishment concept.

Solving the issue of safe operation of motor ships pr. R376 with a superstructure of increased volume, we came to the conclusion that the stability of these ships with developed superstructures is insufficient even when operating in pools of the “L” and “R” categories when installing up to 10 tons of ballast.
Increasing the width of the vessel due to the installation of boules made it possible to significantly increase the volume of the superstructure, make it two-tiered and expand the area of ​​operation of the converted vessels to pools of the "M-Pr" category. The result is a safe vessel with double sides that protect the main hull from damage, with good stability and unsinkability characteristics, with a duplicate aerosol fire extinguishing system in the engine room.

Additional options:

1. installation of a water mist fire extinguishing system in residential premises;
2. installation of armored glass in porthole windows, protecting against penetration through them in the absence of security in parking lots and winter storage;
3. replacement of the main engine with YaMZ-238, NanniDiesel and others;
4. installation of external and internal surveillance and security alarms;
5. installation of thickened or duplicate sheets in the bow of the bottom to preserve the hull plating when moored with the bow to the shore;
6. installation of bow and stern ladders for going ashore;
7. installation of exhaust gas recuperators, allowing to reduce fuel consumption by 20-30%, clean the exhaust from soot and carbon dioxide, and reduce the temperature of the exhaust gas to 40-50°C;
8. Installation of noise-absorbing structures
9. Installation of a wastewater treatment system
10. Installation of a drinking water treatment system
11. Exclusive architectural view of the vessel at the customer's choice
12. Exclusive paint scheme for the vessel
13. Reclassification of the vessel to the "M-Pr" class
