Ship project history: Torpedo motorboats (Schnellboote) were the development of successful prototype created by F. Lürssen in 1929. General characteristic lines for all series were round-bilge hull with small deadrise, triple-shaft diesel machinery, presence of two auxiliary rudders for creation of "Lürssen effect" (fitting of rudders under an angle to centreline for speed increase) and a bow arrangement of two TTs. Composite hull included light alloy framing, wooden planking and steel engine seating.
