During the Second World War, the La Spezia towing tank in Italy carried out model tests of a revolutionary high-speed craft claimed capable of reaching speeds of 60 knots. The concept has since lain dormant, but, as this article describes, a Trieste consultancy is attempting to revive interest in it. In its current form, the design is known as the Potocnik-Pecorini craft. It overturns all traditional methods of propulsion, using a main rotor and a series of eight small lateral "screws" slightly inset into the hull for pushing and rolling water toward the stern. The design is claimed to be appropriate to all classes of vessel, large and small, and the high speeds are said to be possible even in high sea states.
