Project
HSC150B - a catamaran with dynamic unloading by
hydrofoils. Purpose - high-speed passenger transportation on
main river and lake lines, including Lake Baikal.
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 construction of high-speed vessels
of this type is a new experience for Russian shipbuilders.
The creation of a high-speed hydrofoil catamaran was
facilitated by a request for a high-speed vessel project
with strict requirements for speed, seaworthiness, draft and
fuel consumption.
The concept of the vessel was based on
the experience of our friend and partner, the renowned
hydrodynamicist Gunther Migeotte, and his teacher, Professor
Werner Hoppe, in building seagoing vessels.
Distinctive features of the HSC150B
project vessels from Hoppe vessels of the HYSUCAT* (Hydrofoil
Supported CATamaran) type: the arrangement of the wings
relative to the hulls, the configuration of the wings, the
degree of dynamic unloading, the combination of the wing
device with wave-piercing hulls of high aspect ratio.
According to the agreement signed by
the Vympel Shipyard, the East Siberian River Shipping
Company and Mashpromleasing JSC, two HSC150B project vessels
were built in 2024. The construction was carried out in
cooperation with the Irkutsk repair and maintenance
enterprise.
The operation of the catamarans began
with the 2024 navigation on Lake Baikal. The vessels 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.
