Description

The technical field to which the utility model belongs.

The closest prototype in the hull is the passenger motor ship of project No. 544, class “P1,2” of the Russian River Register. The ship was built in a large series at the Moscow Shipbuilding and Shiprepairing Plant (MSSZ).

State of the art

The architectural and constructive type is a single-hull single-screw ship with a superstructure in the fore and aft from the engine room and open decks over the superstructures. A single-rotor circuit creates a control problem due to different circulation radii during maneuvering and substantially depends on the current and wind and is practically uncontrollable in reverse. Large passenger capacity - 175 people - makes any kind of comfort impossible, while half of the passengers are located on open decks. As a means of rescue, there are lifeguards at the rate of one lap per four people. Autonomy of navigation - one working shift or about 100 km. Operation is only possible with a working navigation environment and good visibility. The location of the engine in the middle of the body and the passage of the gross line through the passenger compartment create significant noise (over 70 dB) and vibration.

Designed for short trips (river tram). Handbook of serial river vessels, M., Transport, 1967.
