W. Albert Hickman
William Albert Hickman (22 December 1878 in New Brunswick – 10 September 1957) was a Canadian designer and manufacturer of innovative fast boats. He is best known as the inventor of the Hickman Sea Sled. Biography Born in Dorchester, New Brunswick, Hickman grew up in Pictou, Nova Scotia, as part of a wealthy shipbuilding family. He earned a degree in marine engineering from Harvard University in 1899. He was later a Commissioner of New Brunswick, a lecturer for the Government, a Fellow of the Royal Colonial Institute and a successful novelist. He was highly intelligent but, openly, did not suffer fools gladly and was forever irritating his contemporaries in the marine business. This probably contributed to the low coverage of his ideas in the boating press.Seidman, David"Damned by Faint Praise (article)." 100th issue of ''Wooden Boat'', May/June 1991. A 1940s promotional brochure which was in other respects conventional sales material included this banner heading which revealed ...

Sea Sled, Broadside View, San Diego, California
The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71% of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea. The sea moderates Earth's climate and has important roles in the water, carbon, and nitrogen cycles. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary li ...

PT Boat
A PT boat (short for patrol torpedo boat) was a motor torpedo boat used by the United States Navy in World War II. It was small, fast, and inexpensive to build, valued for its maneuverability and speed but hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively fragile construction that limited some of the variants to coastal waters. In the USN they were organized in Motor Torpedo Boat Squadrons (MTBRONs). The PT boat was very different from the first generation of torpedo boat, which had been developed at the end of the 19th century and featured a displacement hull form. These first generation torpedo boats rode low in the water, displaced up to 300 tons, and had a top speed of . During World War I Italy, the US, and UK developed the first high-performance gasoline-powered motor torpedo boats (often with top speeds over ) and corresponding torpedo tactics, but these projects were all quickly disbanded after the Armistice.

People From Westmorland County, New Brunswick
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Damn With Faint Praise
Damning with faint praise is an English idiom, expressing oxymoronically that half-hearted or insincere praise may act as oblique criticism or condemnation.Ammer, Christine. (2001) ''The American Heritage Dictionary of Idioms,'' p. 153./ref> In simpler terms, praise is given, but only given as high as mediocrity, which may be interpreted as passive-aggressive. History of the term The concept can be found in the work of the Hellenistic sophist and philosopher Favorinus (c. 110 AD) who observed that faint and half-hearted praise was more harmful than loud and persistent abuse. The explicit phrasing of the modern English idiomatic expression was first published by Alexander Pope in his 1734 poem, "Epistle to Dr Arbuthnot" in ''Prologue to the Satires.'' ::Damn with faint praise, assent with civil leer, ::And without sneering, teach the rest to sneer; ::Willing to wound, and yet afraid to strike, ::Just hint a fault, and hesitate dislike. ::::— "Epistle to Dr Arbuthnot" by Alexand ...

Supercavitation Propeller
{{no footnotes, date=November 2016 The supercavitating propeller is a variant of a propeller for propulsion in water, where supercavitation is actively employed to gain increased speed by reducing friction. They are being used for military purposes and for high performance racing boats as well as model racing boats. This article distinguishes a supercavitating propeller from a subcavitating propeller running under supercavitating conditions. In general, subcavitating propellers become less efficient when they are running under supercavitating conditions. The supercavitating propeller operates submerged with the entire diameter of the blade below the water line. Its blades are wedge-shaped to force cavitation at the leading edge and to avoid water skin friction along the whole forward face. As the cavity collapses well behind the blade, the supercavitating propeller avoids the spalling damage due to cavitation that is a problem with conventional propellers. An alternative to t ...

Catamaran
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing ve ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found ...

Hickman Sea Sled
The Hickman Sea Sled is an inverted vee planing hull invented by Albert Hickman. The Sea Sled is a direct forerunner of the modern high speed catamaran or tunnel hull. The reduced friction is due to a "trapped" gas film between the hull surface and water. A similar effect is seen in super-cavitating torpedoes where a gas generator creates a film separation to water friction.
