Pump-jet powered ships are well known to be very maneuverable. Speeds of up to 40 knots can be achieved with this configuration, even with a conventional hull. On these larger craft, they can be powered by diesel engines or gas turbines. Pump-jets were once limited to high-speed pleasure ships (such as jet skis and jet boats) and other small craft, but since 2000–2010 the desire for high-speed vessels has increased and thus the pump-jet is gaining popularity on larger craft, military vessels and ferries in particular. The first person to achieve that was New Zealand inventor Sir William Hamilton in 1954. However, he never applied for a patent, and since the device suffered from material problems resulting in a short life-span, it never became a commercial product. The Italian inventor Secondo Campini showed the first functioning man-made pump-jet engine in Venice in 1931.
