The Radeon R430 chip from ATI Technologies can be found in some models of the Radeon X800 GTO video card.
 The Radeon X800 "R430"-based 110 nanometer series was introduced at the end of 2004 along with ATI's new X850 cards.
 The X800 was designed to replace the position X700 XT failed to secure, with 12 pipelines and a 256-bit RAM bus.
 The card more than surpassed the 6600GT with performance similar to that of the GeForce 6800.
 A close relative, the new X800 XL, was positioned to dethrone Nvidia's GeForce 6800 GT with higher memory speeds and a full 16 pipelines to boost performance.
 R430 was unable to reach high clock speeds, being mainly designed to reduce the cost per graphics processing unit (GPU), and so a new top-of-the-line core was still needed.
Donald Joel Aronow (March 3, 1927 – February 3, 1987) was an American designer, builder and racer of the famous Magnum Marine, Cary, Cigarette, Donzi, and Formula speedboats.
 He built speedboats for the Shah of Iran, Charles Keating, Robert Vesco, Malcolm Forbes, and George H. W. Bush.
 Retired President Lyndon Johnson owned several 16 ft. Donzi speedboats on his Texas ranch with which he would race his Secret Service agents.
Variable-geometry turbochargers (VGTs), (also known as variable nozzle turbines/VNTs), are a family of turbochargers, usually designed to allow the effective aspect ratio (A:R) of the turbo to be altered as conditions change.
 This is done because optimum aspect ratio at low engine speeds is very different from that at high engine speeds.
 If the aspect ratio is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust manifold pressures, high pumping losses, and ultimately lower power output.
 By altering the geometry of the turbine housing as the engine accelerates, the turbo's aspect ratio can be maintained at its optimum.
 Because of this, VGTs have a minimal amount of lag, have a low boost threshold, and are very efficient at higher engine speeds.
 VGTs do not require a wastegate.
The 29er is a two-person high performance sailing skiff designed by Julian Bethwaite and first produced in 1998.
 Derived from the Olympic class 49er class, it is raced in the ISAF Youth Sailing World Championships.
 The 29er is able to reach high speeds fairly quickly by having a sleek and hydrodynamic hull and will often exceed the wind speed when planing both up and downwind.
The Arrow class is a series of fast patrol/assault speed boat constructed by the Sri Lanka Navy for use by its littoral warfare units, the elite Special Boat Squadron (SBS) and the Rapid Action Boat Squadron (RABS).
 The boat is capable of achieving high speeds and is highly maneuverable, meeting the requirements of these units in small boat operations.
 Armed with an autocannon or automatic grenade launcher as its primary weapon system and with multiple machine guns, the Arrow boats provides relatively high firepower despite its small size.
 It is also used by the navy for inshore monitoring operations.
Open Road Racing is a form of regularity rally carried out at high speeds on closed public highways, most commonly in sparsely populated parts of the Southwestern United States.
 Competitors attempt to set specified average speeds which can range from 80 to or higher along courses ranging between 50 and in length.
 At the lower speeds, unmodified production cars can be used, while straightforward safety modifications can permit powerful sports cars to reach speeds of 165 mph .
A go-fast boat is a small, fast boat designed with a long narrow platform and a planing hull to enable it to reach high speeds.
Hydroptère is an experimental sailing hydrofoil trimaran designed by French yachtsman Alain Thébault.
 Its multihull hydrofoil design allows the sail-powered vessel to reach high speeds on water.
 The design is based on experience from a range of hydrofoil sailcraft that Thébault built in cooperation with Éric Tabarly since the 1990s.
 On 5 October 2008 she reached a record speed of 52.86 kn , however this was over a shorter distance than the 500m necessary to qualify for an official world record.
 On 21 December 2008, the "Hydroptère" briefly reached 56.3 kn near Fos-sur-Mer, but capsized and turtled shortly thereafter.
In the early 1940s, Erich Bachem, Fieseler's Aircraft's technical manager, developed two designs for a rocket-launched fighter that could reach high altitudes quicker than conventional fighters.
G.fast is a digital subscriber line (DSL) protocol standard for local loops shorter than 500 m, with performance targets between 150 Mbit/s and 1 Gbit/s, depending on loop length.
 High speeds are only achieved over very short loops.
 Although G.fast was initially designed for loops shorter than 250 meters, Sckipio in early 2015 demonstrated G.fast delivering speeds over 100 Mbit/s nearly 500 meters and the EU announced a research project.

Question: What was the occupation of the man who built a small, fast boat designed with a long narrow platform that could reach high speeds?
Answer: American designer, builder and racer
