The world unlimited water speed record is the officially recognised fastest speed achieved by a water-borne vehicle, irrespective of propulsion method. The current unlimited record is 511.11 km/h (317.59 mph; 275.98 kn), achieved by Australian Ken Warby in the Spirit of Australia on 8 October 1978.
Super Boats - engines in the Super Boat class have no maximum size, but instead have a minimum size restriction. Normally aspirated engines must have a displacement of 6.5 litres (400 cubic inches), while forced induction (turbocharged or supercharged) engines must be at least 3.8 liters (235 cubic inches) in displacement.
A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern.
In 2002, the Swedish Navy ordered an additional 27 boats of a slightly different type, designated Stridsbåt 90 HS – where S refers to Skydd (protected) [2] as the Strb 90 HS is armoured and features CBRN protection (the whole boat can be over-pressurized) – intended for use in international peace-keeping operations. Apart from the addition ...
This increases lift and reduces drag, so that at speed only a few inches of the boat touch the water, leading to the high speed possible with these hulls. [11] F1 boats are powered by a Mercury Marine [citation needed] V6 two stroke that burns 100LL Avgas at a rate of 120 liters (32 gallons) per hour, generating over 400 horsepower at 10,500 ...
The FAST ecosystem has several layers. The best-known FASTs are the aggregators, which fall into three categories. FASTs owned by major media companies: Paramount's Pluto TV, Fox's Tubi, Charter Communications and Comcast's Xumo Play, Dish Network's Sling Freestream, ITV’s ITVX service, NEW ID's BINGE Korea, [3] Allen Media Group's Local Now, and Gray Television and National Association of ...
It had a design speed of 250 miles per hour (400 km/h) and remained the only successful jet-boat in the world until the late 1960s. From the brief of the mid 1950s, Blubird K7 was designed [5] to: To attain a speed of 250mph commensurate with an adequate margin of static and dynamic stability in yaw, pitch and roll.
There have been several versions of the Miss GEICO boat, including one of the fastest offshore powerboats in the world. The most powerful was a 50' Mystic powered by twin Lycoming T-53 turbine engines, reaching speeds exceeding 210 mph (340 km/h); which caught fire during testing on June 30, 2012, in Sarasota, Florida , and burned to the ...
