The purpose of the vessel of proj. HSC150B is high-speed passenger transportation on the main river and lake lines. Hull type - hysucat* - sharp-chine hull with catamaran-type contours with a hyrofoils.

Operating conditions - the vessel can be operated for its intended purpose all year round on ice-free water, in hyrofoil or displacement mode, depending on weather conditions. Navigation area - pools of category "M", including those on Lake Baikal. The project provides for the disembarkation of passengers on an unequipped shore.

The operation of the vessels is scheduled to begin in July 2023.

The ships were named Sarma and Selenga in honor of the Baikal winds and the rivers of the same name flowing into Baikal.

* Vessel of the Hysucat type is a catamaran with a system of hydrofoils located in the dimensions of the largest width of the hull or slightly exceeding it.

Compared to the traditional speedboat of the same speed, the hysucat uses 40% less fuel and carries 8% more payload.

Compared to the traditional hyrofoil with fixed hydrofoils, the hysucat can be operated at shallower depths, is less dependent on overload, has a relative simplicity of the hydrofoils design, and the situation of not lifting on hydrofoils is excluded.
