Skeg

Skeg (pronounced skeg)

(1) In shipbuilding, a fin-like projection supporting a rudder and protecting the propeller(s) at its lower end, located abaft a sternpost or rudderpost.

(2) In the design of smaller boats, an extension of the keel, designed to improve steering.

(3) In the slang of naval architects (in certain contexts), a stump or branch (the after-part of a ship's keel).

(4) In the slang of the General Motors (GM) stylists, a “lower fin”, matching the upper on the rear of 1961-1962 Cadillacs.

(5) The fin which acts as a stabilizer on a surfboard.  To suffer some injury after being hit by one of these fins is to be “skegged”.

(6) In Australian slang, a surfer; a person who leads the lifestyle of a surfer (used also derisively in the form “fake skeg” of those who adopt the style an appearance without actually surfing.

(7) A type of wild plum (obsolete).

(8) A kind of oat (obsolete).

(9) In Northern English dialectal use, a look or glance.

(10) In many cultures, a slang term applied to youth suggesting slovenliness, a predilection to petty crime and other anti-social behavior; also used widely in Scottish slang for a surprising variety of purposes including legs, trousers, dirt, scotch eggs, sex and women of loose virtue.

1590–1600: From a dialectal term for a stump, branch, or wooden peg, from the Dutch scheg (cutwater), of Scandinavian origin and related to the Swedish skog and the Old Norse & Icelandic skegg (projection on the stern of a boat).  In some Nordic languages, skegg means “beard” and was from the Old Norse skegg, from the Proto-Germanic skaggiją, from the primitive Indo-European skek, kek-, skeg & keg- (to jump, skip, move, hurry).  The name of the English coastal town of Skegness is though a construct of the Old Norse skegg (beard) + -nes (headland) and was thought a reference to the geography, the original settlement situated farther east at the mouth of The Wash (thus jutting out like a beard from a face).  A link with the Old Norse name Skeggi is thought unlikely.  The skegs of nautical architecture should not be confused with the homophone Sceggs, the acronym for students of Sydney Church of England Girls Grammar school (S.C.E.G.G.S.), seen also in the adjectival forms sceggesque & sceggish (one whose style suggests something similar to the stereotypical student of the school).  Skeg is a noun; the noun plural is skegs.

On nautical vessels, skegs where they exist fulfill a significant function but they are not an essential part of hull design.  A skeg is an external structural feature, a vertical tapering projection permanently fixed at the aft, usually close to the centre-line.  Most are located in front of the rudder and structurally can often be considered a sternward extension of the keel (the internal, longitudinal members which lend much strength of the hull).  Although in military vessels there are additional functions, the moist significant contribution of a skeg is in hydrodynamics, a skeg designed to influence the flow patterns and thus affecting the dynamics of both the rudder (which is usually in line with the skeg) and propeller(s).  The design is thus a finely tuned equation because while a skeg inherently induces drag, the way it alters the flow pattern can reduces the drag and resistance suffered by the rudder and propeller(s), essentially by transforming the turbulent characteristics of the flow to laminar at the stern.  Historically, skegs were a vital component in maintaining a course and that’s still an important consideration in smaller vessels but in larger craft, improved rudder and advanced navigational as well as stabilization technologies like thrusters have meant skegs are no longer of the same significance in maintaining directionality.

In the modern age, skegs became an unusual feature on warships, a relative few so equipped and the designs varied, some with only a few of their shafts inside skegs while others encased all.  While the traditional design imperatives were shared with other ships, for navies, they also offered the advantage of affording some degree of protection for rudders and propellers against torpedo attack.  Historically, another important attribute of skegs was what they add to a hull’s structural strength, making the (inherently weaker) stern resistant to outside forces and all the last of the US Navy’s dreadnoughts featured skegs.  Their hulls narrowed towards the stern and to save weight lacked the sternpost plates the British, German and Japanese navies always fitted to their battleships and the skegs compensated for this, offering a hull with similar rigidity.

The US Navy’s South Dakota class battleships were fitted with an unusual set of skegs, the design dictated by the relatively short hull, the large outboard skegs helping to reduce the adverse effects of fluid dynamics induced by the hull’s abrupt end.

However, advantages in engineering and metallurgy meant much of the functionality afforded by skegs could be achieved in other ways and skegs became unfashionable in naval architecture.  The modeling and simulations made possible by supercomputers meant hull designs could be rendered which mastered the turbulence caused by fluid dynamics so rudders and propellers were less affected so the skeg was in many cases a source of performance-sapping skin-friction drag with little compensating benefit.  Indeed, not only did this hamper performance, in some cases excessive vibration was caused, something which could only to a degree be ameliorated by changes to the propellers’ configurations.

Cadillac’s Skegs, 1961-1962

Cadillac Coupe DeVille, (1959, left & 1960 right).

The 1959 Cadillac’s tail-fins are the best remembered and most emblematic of the brief, extraordinary era during which the absurdly macropterous flourished.  They’re rightly known as “peak-fin” but it’s a myth they were the tallest because, measured from the ground, those on the 1961 Imperial are just under an inch (25 mm) more vertiginous.  The attractions of the style however were fading and in 1960, Cadillac and Chrysler (Ford never really got involved) began to tone them down.  Another cultural phenomenon is that because of the large number of pink 1959 Cadillacs which now exist, many assume they were a common sight when new, the things perhaps made memorable by the sight of the one owned by the admirable Jayne Mansfield (1933–1967).  However, the factory never made a pink 1959 Cadillac and in the era, it was only in 1956 such a color was on the option list and Ms Mansfield had one of those while her 1959 convertible received a custom re-paint.

For the 1961 & 1962 range the fins became lower still but in compensation, the design staff added a lower fin and these, informally they called “skegs”.

While of course an extravagance, the skegs could have part of something even wilder because among the design proposals which emerged from the General Motors Advanced Design Studios was one which clearly was the ultimate expression of the motif of the 1950s which borrowed so much from the aerospace industry,  The proposed fins essentially were those of ballistic missiles which for decades were an evolution from the German Vergeltungswaffen zwei (V-2), developed first by the German military with the code name Aggregat 4 (A4).  Vergeltungswaffen is translated variously as "retaliatory weapons" or "reprisal weapons" but in English use is often written as “vengeance weapons”.  Aerodynamically, presumably the proposal has something to commend it and it proceeded far enough into the selection for an expensive, full-sized clay model to be rendered (one wonders what the rejected sketches looked like) but ultimately the longer though somehow more restrained skegs were preferred.

The 1961 Cadillac: The long (left) and slightly less long (right) of it.

One quirk of Cadillac’s brief embrace of the skeg was there were two iterations: skeg long and skeg short.  Whether in response to or in anticipation of some owners preferring their Cadillac in a more conveniently sized package, between 1961-1963 a “short-deck” option was made available on certain body styles.  Offered first on the six-window Sedan de Ville, an encouraging 3,756 were built so the option was in 1962 offered on the four-window Sixty Two Town Sedan but sales actually dropped to 2600, the decline in interest confirmed the next year when only 1575 of the four-window Park Avenue Sedan de Ville were sold.  Using the same 129.5 inch (3289 mm) wheelbase as the regular models but eight inches (200 mm) shorter in overall length (215 vs 223 inches (5461 vs 5664 mm)), space utilization was obviously a little better but the market had spoken.  With fewer than eight-thousand of the short-deck models sold across three seasons while the standard editions shipped in the tens of thousands, the flirtation with (slightly) more efficient packaging was abandoned for 1964; in the course of the following decade, Cadillacs would grow another seven inches (178 mm) and gain over 400 lb (181 kg).

For 1963, the short-deck models returned for another dismal season but the skegs were abandoned, never to return.  The fins however the design studio found harder to forsake, conscious perhaps it was on the 1948 Cadillac they’d first appeared.  Then, modestly sized, they’d been an allusion to the tail-planes used on the twin-boomed Lockheed P-38 Lightning (1939) but the fashion had passed and the fins had to go so, inch by inch, there was a retreat from the heights and exuberance of 1959 until in 1966 the fins were vestigial, a hint which for decades would be retained.

Handshake

Handshake (pronounced hand-sheyk)

(1) A gripping and shaking of (traditionally the right) hands by two individuals, as to symbolize greeting, congratulation, agreement or farewell.

(2) In digital communication, as handshaking, an exchange of predetermined signals between a computer and a peripheral device or another computer, made when a connection is initially established or at intervals during data transmission, in order to assure proper synchronization.

1801: The construct was hand + shake.  Hand was from the Middle English hond & hand, from the Old English hand, from the Proto-West Germanic handu, from the Proto-Germanic handuz (and related to the Dutch, Norwegian Nynorsk & Swedish hand, the Danish hånd, the German Hand and the West Frisian hân) of uncertain origin although there may be a link to the Old Swedish hinna (to gain), the Gothic fra-hinþan (to take captive, capture), the Latvian sīts (hunting spear), the Ancient Greek κεντέω (kentéō) (prick) and the Albanian çandër (pitchfork; prop).  Shake was from the Middle English schaken, from the Old English sċeacan & sċacan (to shake), from the Proto-West Germanic skakan, from the Proto-Germanic skakaną (to shake, swing, escape), from the primitive Indo-European skeg-, keg-, skek- & kek- (to jump, move).  It was cognate with the Scots schake & schack (to shake), the West Frisian schaekje (to shake), the Dutch schaken (to elope, make clean, shake), the Low German schaken (to move, shift, push, shake) & schacken (to shake, shock), the Old Norse skaka (to shake), the Norwegian Nynorsk skaka (to shake), the Swedish skaka (to shake), the Danish skage (to shake), the Dutch schokken (to shake, shock) and the Russian скака́ть (skakátʹ) (to jump”).  The present participle is handshaking and the familiar past participle handshaked but some dictionaries still list the rare handshook as an alternative; the noun plural is handshakes.

The handshake not a universal cultural practice (the Japanese famously favor the bow although in recent decades it’s executed often as more of a nod) but, in one form or another, it is global and involves usually two people grasping hands and moving them in a brief, up-and-down movement.  The right hand tends to be favored (left-handers sinister obviously) and this has been linked to the symbolism of that being the usual choice when wielding a weapon but that is speculative and the global preponderance of right-handedness may be of greater significance.  Quite when the handshake became a cultural practice isn’t known but it is certainly ancient, at least among those important enough to be depicted in forms of art because the oldest representations date back more than the-thousand years.

Some handshakes promised much; results were varied.  Clockwise from top left:  Mao Tse-tung & Richard Nixon (1972), Yitzhak Rabin & Yasser Arafat (1993), Mikhail Gorbachev & Ronald Reagan (1985), Donald Trump & crooked Hillary Clinton (2016), Martin McGuinness & Queen Elizabeth II (2012) and Nelson Mandela & FW de Klerk (1994). 

Handshake (hand-shake) is a surprisingly modern construction, dating only from 1801 and "hand-shaking" is attested from 1805; the phrases “to shake hands” & “shaking hands” have been in use since the sixteenth century and the use of the noun “grip” to mean "a handshake" (especially one of a secret society) dates from 1785.  Secret handshakes are created so members of clubs and societies may make their affiliation known to another person without needing to use words.  For a secret handshake to be effective it must be specific enough to be recognized by another member yet subtle enough that a non-member would not find the nature of the grip strange or unusual.  Because of the limited possibilities offered by fingers and thumbs, some secret handshakes involve also actions such as using the other hand to touch an earlobe in a certain way or a tapping a foot.  The concept has been documented since Antiquity and is most famously associated with the Freemasons but to speak of the “secret Masonic handshake” is misleading, some researchers claiming there are at least sixteen distinctly identifiable Masonic handshakes and most have speculated there will be dozens more.  Indeed, except in the early years, Freemasonry has never been monolithic and there are known cases of one faction (even within a lodge) developing their own so that they might discuss matter freely without the risk they may be spilling secrets to the other faction.  The mechanics of the secret handshakes used by members of the Secret Society of the Les Clefs d’Or are not known.

The golden handshake is a clause in executive employment contracts that provides for a generous severance package in certain circumstances.  Created originally as a relatively modest inducement to attract staff to companies in a perilous financial position, they evolved to the point where multi-million dollar pay-outs were common and they became controversial because they appeared to reward failure and there were suggestions (not only by conspiracy theorists) they were used even as Trojan horses to entice a CEO to drive down a company’s share price (thus becoming eligible for a golden handshake) in the interest of asset strippers and others.  The best operators were able to engineer things so they enjoyed both a golden handshake and a golden parachute (the generous package payable upon retirement in the normal course of things).

In computer communications, a handshake is a signal exchanged between two or more devices or programs to confirm authentication and connection.  In the same way that the human handshake is a process: (1) an offer of a hand, (2) the taking of that hand and (3) the shaking of the hands, in computing, the sequence is (1) seeking a connection, (2) verifying the connection and (3) effecting the connection.  The breaking of the handshake and the termination of the connection in each case constitutes the final, fourth setup.  The purpose of handshaking is to establish the parameters for the duration of the session which involves the devices agreeing on vital stuff like (1) both being switched on, (2) both ready to transmit & receive and (3) that certain technical protocols will be used (familiar to many as famous strings like “9600,N,8,1”).  Handshaking historically was a process separate from the security layers which had to be satisfied once communication was established and again, this is analogous with the handshake in the process of human interaction.

The Duce emulates an illustrious Roman forebear.

As a cultural practice with a history known to date back at least ten thousand years, the handshake has proven a resilient tradition which has survived the vicissitudes of many millennia and even the preference of elbow-bumping and such during the COVID-19 pandemic seems only to have been a minor interruption.  Not all however approved.  The Duce (Benito Mussolini, 1883–1945; prime minister and Duce (leader) of Italy 1922-1943) thought handshaking effete and unhygienic (he was ready for pandemics) and preferred the fascist salute he thought (apparently on the basis of statues from Ancient Rome) more martial.  Still, when meeting friends (even those forced on him by the brutishness of political necessity) he shook hands and a handshake was both his first and last interaction with the Führer (Adolf Hitler, 1889-1945; German head of government 1933-1945 and of state 1934-1945).  Their smiles when shaking hands always seemed genuine and were noticeably warm when they parted after the attempt on Hitler’s life in July 1944.

One historian entitled his work on the relationship between Hitler and Mussolini The Brutal Friendship and that it was but it was certainly enduring.  They shook hands on many occasions, the last of which would happen on the railway station platform close to where the attempt on the Führer's life failed.  At this time, Hitler was using his left hand to shake, the right arm injured in the blast.  After this, they would never meet again.  

For politicians, handshakes are a wonderful photo opportunity and some have been famously emblematic of the resolution of problems which have been intractable for decades or more.  However, such photographs can be unpleasant and sometimes embarrassing reminders of a past they’d prefer was forgotten.  When Donald Rumsfeld (1932–2021; US secretary of defense 1975-1977 & 2001-2006) shook hands with Saddam Hussein (1937–2006; president of Iraq 1979-2003) in Baghdad in December 1983, it was as a presidential envoy of Ronald Reagan (1911–2004; president of the US 1981-1989) and he was there to do business with the dictator.  Iraq at the time had started a war with Iran and was using chemical weapons while practicing abuses of human rights on parts of the Iraqi population and Saddam Hussein had even made known to the US administration Baghdad’s intention to acquire nuclear weapons.  Thus was special envoy Rumsfeld dispatched to offer Washington’s hand of friendship, anybody opposed to the Ayatollahs held in high regards in Washington DC. 

Donald Rumsfeld and Saddam Hussein, Baghdad, 1983.

Despite what Mr Rumsfeld would claim twenty years on, he made no mention of chemical weapons or human rights abuses, his discussions instead focusing on the projection of US military force in the Gulf and the need to guarantee and protect the supply of oil.  Later, as international pressure increased on the US to condemn the use of chemical weapons by Iraq it responded with a low-key statement which made no mention of Iraq and actually stressed the need to protect Iraq from Iran’s “ruthless and inhumane tactics”.  When Mr Rumsfeld returned to Baghdad in 1984, during the visit the United Nations (UN) issued a report which stated chemical weapons had been used against Iran, something already known to both the Pentagon and state department.  In Baghdad, the matter wasn’t mentioned and when Mr Rumsfeld departed, it was with another warm handshake.

Nancy Pelosi and Bashar al-Assad, April 2007.

By virtue of her education in a Roman Catholic school, Nancy Pelosi (b 1940; speaker of the US House of Representatives 2007-2011 and since 2019, member of the house since 1987) was well acquainted with the Bible so after shaking hands with Bashar al-Assad (b 1965, President of Syria since 2000) in April 2007, to use the phrase “The road to Damascus is a road to peace” must have been a deliberate choice.  It might also be thought a curious choice given that at the time the president was providing shelter and protection to a range of terrorist groups involved in attacking US forces in Iraq.  As speaker of the house, Ms Pelosi would have received high-level intelligence briefings so presumably was acquainted with the facts and had she been uncertain, could have had aides prepare a summary from publicly available sources.  As recent events in the Far East have illustrated, the speaker’s forays into foreign affairs are not helpful to the State Department.
