The Project 1390 command crew boat, developed by order of the Navy, combines aesthetics and excellent performance. Despite the low speed of 13 knots, the boat shows good seaworthiness, withstanding waves of 4-5 points. The material for the structural elements was aluminum alloy AMg5. The hull is assembled according to a transverse pattern with a distance between frames of 0.45 m.

The boat in the photographs has seen a lot, but still, it is beautiful!

Watertight bulkheads installed in the area of ​​frames 4 and 8 divide the hull into sealed compartments, ensuring the vessel's unsinkability. Argon-arc welding is used to connect the parts of the structure to each other and the sheathing sheets. The boat has a deckhouse with three berths and an open area for passengers.

At the bow of the vessel there is a large hold for equipment. Remote control boat and work control power plant carried out from the control station.

And there are also perverts who farm these boats:

In the post-war period, raid boats were created by order of the Soviet Navy. They were intended as auxiliary boats to support the daily activities of other ships in their anchorage areas. Later, on their basis, they began to build civilian modifications that perform various purposes:

• Workers;
• Diving;
• Hydrographic;
• Towing;
• Underwater protection of objects;
• Medical;
• Rescue.

Raid boat RK-1078

Boat "Yaroslavets"

Engineers designed the Yaroslavets in the 50s. XX century. The Soviet Navy needed a tugboat that could be used for search and rescue operations involving divers, as well as at customs and border posts.

One of important characteristics boat is its ability to transport railway. In any modification, the length of the vessel is 21 meters and the width is 4 meters. Its displacement is almost 47 tons. The vessel accommodates 12 people.

The power plant consists of two diesel engines, models ZD6S and ZD6S1, which drive one fixed-pitch propeller. This allows the boat to accelerate to 10 knots.

Raid boat “Yaroslavets” RK – 516

The boat is designed in such a way that it is possible to quickly deliver cargo or divers to the site and ensure their uninterrupted work. It can perform maneuvers in shallow water and shallow ice surfaces.

The ship's hull is made of wood and metal. The towing modification is equipped with special arches that prevent damage to the cable during maneuvers. There is also a special hook on board for lifting cargo and towing ships. The vessel's wheelhouse is removable. This was done in order to reduce the size when transporting the boat by rail.

The boat is used as vehicle for transportation of goods and passengers. Its functions also include towing other ships and participating in search operations. It is used in border protection and to catch poachers.

Raid patrol boat "Sapsan"

The vessel was designed by Almaz Design Bureau. Its function is to transport official delegations, officers and commanders of the fleet from shore to shore or to ships that are at anchor. The boat is also intended for participation in parades.

“Sapsan” is a twenty-meter boat with a smooth deck, a single-tier deckhouse, a steel hull and an aluminum alloy superstructure. It displaces up to 103 tons of water. It has two MTU10V200M9 diesel engines that help it reach speeds of up to 20 knots. The ship has five cabins that can accommodate 10 people. In closed and open salons accommodates 20 people each. The ship also has an open bridge, cockpit and cabins for crew members.

The boat was recently accepted into the ranks and is now based in Sevastopol.

Raid boat "Vodolaz Pechkurov"

The vessel is involved in various diving, search and rescue operations and ship lifting operations. The length of the boat is almost 28 meters, the width is five and a half meters. The displacement of water is 92.7 meters.

The boat is equipped modern equipment for diving work:

• Diving suits with helmets;
• Wetsuits with an open breathing pattern;
• A special diving chamber for 4 people for lowering the crew to the bottom;
• Communication system, device for lowering and lifting divers;
• Tools for welding and soil erosion, tools for grinding, cutting, splitting iron and concrete under water.

This equipment allows divers to dive to a depth of up to sixty meters at any time of the day or night. The stability of the boat allows scuba divers to work in stormy water.

"Baklan" is a large single-deck boat. It was created to reconnaissance routes, survey the bottom topography, and assist in the navigation of submarines in coastal waters. It is capable of delivering cargo and research groups to unequipped coasts.

The length of the vessel is 36.4 meters, width -7.6 meters. The ship's displacement is 320 tons. A Dreggen crane is installed on the deck, which is capable of lifting cargo weighing up to 3.5 tons. The engine room contains two Deutz diesel engines with a total power of 464 kW. "Cormorant" accelerates to 11-12 knots. Its crew consists of 11 people.

The latest hydrographic, navigation and communication equipment is installed on board the boat. These include: multibeam and measuring echo sounders, a seaograph, a device for measuring pitching, a profiler, equipment for measuring the speed of sound in water. The boat is equipped with radio installations, NAVTEX receivers, a navigation locator and a GLONAS satellite station.

The raid boats are not equipped with any weapons, since they are auxiliary vessels for military and civilian vessels and are used in peacetime.
