A hydroplane (or hydro, or thunderboat) is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy. A key aspect of hydroplanes is that they use the water they are on for lift rather than buoyancy, as well as for propulsion and steering : when travelling at ...
Blue Bird K3 is a hydroplane powerboat commissioned in 1937 by Sir Malcolm Campbell, to rival the Americans' efforts in the fight for the world water speed record. She set three world water speed records , first on Lake Maggiore in September 1937, then later twice raising her own record.
Unlike conventional powerboats, which have a single keel, with an indent, or 'step', cut from the bottom to reduce drag, a hydroplane has a concave base with two sponsons fitted to the front and a third point at the rear of the hull. When the boat increases in speed, most of the hull lifts out of the water and runs on the three contact points.
The result was a 502 bhp speedboat, which he used to hit a 150.19 mph top speed in October 1953 on Lake Iseo. This world speed record for an 800 kg boat still stands today. [3] A similar hydroplane was constructed by Guido Monzino in 1954. Like Arno XI, it utilizes a Lampredi engine, in this case sourced from a wrecked Ferrari 375 MM. [4]
He also chaired the planning committee of the Quincy Boat Club, the organization responsible for sponsoring many of Quincy's races and related celebrations. [2] He won trophies [ 3 ] and in 1924 at Palm Beach, Florida , in competition with twenty-one other boats in the 151-class hydroplane races, he clocked a world record 41.96 miles per hour ...
H1 Unlimited is an American unlimited hydroplane racing league that is sanctioned by the American Power Boat Association (APBA). Until 2009, the series was known as ABRA Unlimited Hydroplane, in turn renamed from APBA Unlimited Hydroplane in 2004.

Pinaud's experience in boat-building enabled him to make useful design changes to HD-4. After the First World War , work began again on HD-4 . Bell's report to the U.S. Navy permitted him to obtain two 350 brake horsepower (260 kW) Liberty V-12 engines in July 1919.
