That day the No-Vac set the world water speed record for an outboard powered boat of 78 miles per hour (126 km/h). The basic hull design of most hydroplanes has remained relatively unchanged since the 1950s: two sponsons in front, one on each side of the bow; behind the wide bow , is a narrower, mostly rectangular section housing the driver ...
The basic design has a displacement of 1,100 tons while measuring 79.9 metres (262 ft) long at waterline and 22 metres (72 ft) broad. Power is provided by a CODOG arrangement comprising two MTU 595 diesel engines and two LM2500 gas turbines. Diesel power is used for cruising while the turbines provide high-power output for high-speed operation.
The Lürssen effect, used in the design of high-speed boats, is a reduction in wave-making resistance provided by two small rudders mounted on each side of the main rudder and turned outboard. These rudders force the water under the hull outward, lifting the stern, thus reducing drag, and lowering the wake height, which "requires less energy ...
Tarifa Jet, a high-speed wavepiercer catamaran by Incat. A high-speed craft (HSC) is a high-speed water vessel for civilian use, also called a fastcraft or fast ferry. The first high-speed craft were often hydrofoils or hovercraft, but in the 1990s catamaran and monohull designs become more popular. Most high-speed craft serve as passenger ...
Hull speed. Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in ...
Planing (boat) A Contender dinghy planing on a broad reach. Note the typical way the bow lifts up while the stern skims over the water. Planing (/ ˈpleɪnɪŋ / PLAY-ning) is the mode of operation for a waterborne craft in which its weight is predominantly supported by hydrodynamic lift, rather than hydrostatic lift (buoyancy).
Boat building. Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull, with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires. [1]
The twin hulls (blue) remain completely submerged. A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even ...
