Yaroslavets- the name of the series of utility boats.

By 1948, in the design bureau of SMEs, a project of a multipurpose boat was developed and approved for the needs of the Navy and the national economy. The boat of the "I" type, which was produced in the 1930-1940s, was taken as a basis. The project received the number 376 and the code "North". In 1953, the lead boat of the project was launched at the shipyard No. 345. The boats of the project got their name - "Yaroslavets" by the name of the enterprise. The second enterprise where the production of boats began was Sosnovsky Shipbuilding Plant 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, Bulgaria.

Refit concept.

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

Additional options:

1. installation of a water mist fire extinguishing system in residential premises;

project R376, R376U, RM-376, RVM-376 type "Yaroslavets"
Ships 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 various enterprises, in versions of tug, crew, diving and other vessels. Project author: KB SME.
R-376, R-376U- A single-screw tug with a saddle deck, a wheelhouse and a superstructure on the deck, with a canopy above the MO and aft cargo hold. Purpose - towing small vessels, transportation of 10-15 tons of cargo in holds, transportation of up to 12 passengers. The boat can be transported on railroad with the superstructure removed from the deck. (Serial Transport Ship Handbook, Volume 3, pp. 179-181 OPEN) project P376 project P376Have In 1948, in the design bureau of the SME, the project was approved a tugboat for the needs of the Navy and the national economy. The project was assigned a number - 376 and code - "North". The project envisaged 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 ability to transport the boat by rail. In 1953, at Shipyard No. 345 (now Yaroslavl Shipyard)the lead boat of Project 376 was launched. enterprises, the project received a semi-official name - "Yaroslavets" - instead of a cipher that was forgotten over time. The construction was immediately launched in a large series. The second large enterprise, which began to build boats of Project 376, was the Sosnovsky Shipbuilding Plant, Shipyard No. 640. In 1955-57, an improved model of the boat was developed, which received the designation - 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 off manufacturability of production. As a result, it turned out to be 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 wheelhouse and a superstructure on the deck, with a canopy above the MO and aft hold. The hull of the boat is made all-welded according to the transverse pattern of the set... It has 6 watertight bulkheads, 3 bottom fuel tanks. The dimensions of the hull are made with the condition of transporting the boat by rail with the superstructure removed.The drawings below show the marking of the welded seams of the side skin and deck flooring, made from photographs of the boats. The width of the welded seams is 4 to 10 mm. It should be noted that on many boats during the repair, non-standard sheathing sheets or patches appear. As an example, see the explanation to the drawing of the boat "Olympus". The design of the boat is adapted for sailing in shallow broken ice. This is due, inter alia, to the presenceice kingston, whichwarm water is supplied to the external cooling circuit of the main engine,stem design,the presence of ice reinforcement in the bowhulls in the form of a powerful T-beam. A very powerful was used in the structural structure of the hull. strip-bulbs as the basis for frames and beams, strips, corners, plates for the manufacture of ribs and other structural elements are also used, and in the later series of Project 376U, many welded elements are replaced with bent profiles. The steering wheel on the boat is balanced with a streamlined shape. The boats of the project 376 had only one rudder blade (Fig. 3, Fig. 6). The 376U has two rudder feathers (Fig. 4, Fig. 5a). Accordingly on upper deck one or two plugs covering the tiller mounting holes. (The so-called "glasses" are screw plugs of the holes into which the tiller is inserted in order to control the boat manually if the drive steering cables are suddenly torn). Fig. 3 Fig. 4 The rudders are made hollow, welded from sheet metal (Fig. 5). The feather has no lower support and its loss is not uncommon. For self-repairs, a simpler pen is installed - flat, made of a sheet of metal, with ribs (Fig. 5a). The pen is fastened with six bolts for a rectangular (on Project 376U boats - Fig. 5 and Fig. 5a) or a round flange (on Project 376 boats - Fig. 6). fig. 5 fig. 5a rice. 6 There are 6 windows on the left side of the boat. The porthole closest to the stern is sometimes welded up, because it is too close to the surface of the water. This usually happens during conversions when a lot of ballast is put in and the boat's draft increases. There are only four portholes on the starboard side. Three scuppers are located above the waterline (outlets of water drain pipes from the deck). Between the first and second scuppers there is a branch pipe for the cooling system of the auxiliary engine. The fenders running along the hull of the boat were made of both wood and metal. Apparently, initially factories made them from wood, and in the troops 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 rib (in section "E"). Figure 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 . Regular wooden beams. Plates and rings for fastening fenders, brackets for fastening a bar and a steel strip along the bar are visible. Fig. 7 a.Regular wooden beams. The fixed nose fender is visible. The superstructure on the upper deck is represented by the wheelhouse and the cap engine room... Coaming runs along their bottom. The wheelhouse of the boat is removable. This allows the boat to be transported by rail. It is bolted to the coaming and the front of the mouthguard. The boats of projects 376 and 376u have wheelhouses of various designs. The cabin of the boats of the project 376 is made of smooth sheets. with welded ribs inside... And the boats of the project 376u are made of sheets with vertical stampings. The corners of the felling are rounded off with a radius of 100mm. It should be noted that sometimes there are boats in which wheelhouses were installed on the hull of the project 376 from the boat of the project 376u (see photo "Zuyka"). On the left side of the wheelhouse there are three doors and a rectangular window in the front of the wheelhouse. Of these, the front door was slightly higher. A welded footrest led to it from below. The middle door is sealed. She leads to the radio room. The door located closer to the stern (leads 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 of the wheelhouse and two round porthole... On some boats, the windows in the wheelhouse are made opening - they slide down. By design, the doors were different from each other. On the boats of the project 376, they had loops of a different design than on the boats of the project 376u. There are four series of doors in total. The earliest models featured simple hinges and handles on each of the locks. On sealed doors, their number reached seven. In the future, a lever drive of the locks and one handle on the side of the door were used. More reliable hinges were also introduced. On the latest doors, the central locking system is a spring latch. Figure 9-10.

A hook is attached to the rear wall of the wheelhouse. In the same place, on the boats of the project 376u, there was a brace-ladder leading to the navigating bridge (Fig. 11). On the boats of the project 376, instead of the ladder-ladder, a removable ladder was installed, fixed on bolts(fig. 1 2) ... The handrails of the ladders are also different: inclined (on the 376u project) or vertical (on the project 376).

Cap on boats of all projects is not removable. It also differed somewhat among boats of different projects. The boats of project 376 the leaf at the top of the burl, and a removable sheet above the MO (intended for dismantling the main and auxiliary engines and mechanisms), made of a flat sheet with stiffening ribs from corners and strips welded to it, and in the 376y - from the profiledsheet without welded reinforcements(fig. 1-3) ... Some Project 376 boats have no portholes on the removable burl sheet.

Towing arcs were installed on the cap and in the aft part of the hull. They are designed to prevent damage that can be caused by the towing line during maneuvers. On boats that are not used as towing boats, the stern towing bow is not is installed. In this case, the arc located on the MO mouthpiece, as a rule, arcs are executed of several types. Cast, with a profile in the form of a channel, or tubular. In the aft part of the burl, in the center plane, there is a swing hatch to the interior.(fig. 14).

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