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 ...
Daniel Dehaemers was the Belgian challenger for the absolute water speed record. [29] The SP600 is of full carbon composite construction. It is powered by a Rolls-Royce Adour 104 turbojet engine. The boat was planned to be tested in 2016. However, after finishing building the boat, he died of cancer in 2018 before he managed to trial the craft ...
HTML Form format HTML 4.01 Specification since PDF 1.5; HTML 2.0 since 1.2 Forms Data Format (FDF) based on PDF, uses the same syntax and has essentially the same file structure, but is much simpler than PDF since the body of an FDF document consists of only one required object. Forms Data Format is defined in the PDF specification (since PDF 1.2).
The design of watercraft requires a tradeoff among internal capacity (), speed and seaworthiness.Tonnage is important for transport of goods, speed is important for warships and racing vessels, and the degree of seaworthiness varies according to the bodies of water on which a watercraft is used.

Royal Navy World War II motor torpedo boat planing at speed on calm water showing its hard chine hull - note how most of the forepart of the boat is out of the water. At rest, a vessel's weight is borne entirely by the buoyant force. Every hull acts as a displacement hull at low speeds: the buoyant force is mainly responsible for supporting the ...
David Vinckboons: Landscape with skaters (cca. 1615), 17th century boer type iceboats Boer Ice sailing in the Netherlands in 1938.. An iceboat (occasionally spelled ice boat or traditionally called an ice yacht) is a recreational or competition sailing craft supported on metal runners for traveling over ice.
Apparent wind is the wind velocity (direction and speed), V A, measured aboard a moving sailing craft; it is the net effect of the boat wind, V B —the air flow over the craft induced by its speed over the earth (equal to in magnitude, but opposite in direction to the craft's speed)—and the true wind, V T.
