Siren

Siren (pronounced sahy-ruhn)

1300-1350: From the Middle English siren & serein, from the Old French sereine, (the Modern French sereine dating from the twelfth century), from the Late Latin sīrēna and the Classical Latin Sīrēn & Sīrēna, from the Ancient Greek Σειρήν (Seirḗn).  The Seirēnes were the alluring sea nymphs of classical mythology and the figurative sense of “one who sings sweetly and charms” was first noted in the 1580s although the classical descriptions of them were mangled in medieval translations, resulting in some odd and fantastical notions of their appearance and it wasn’t unusual for them to be conflated with mermaids.  The Vulgate (the Biblia Vulgata, the fourth century translation of the Bible which, through the choices of words and senses made by the translator(s) had a profound effect on Christianity and Christendom) also gifted to Middle English the use of the word to describe an imaginary species of flying serpents, based on glossary explanations of the Latin sirenes in Isaiah 13:22 (“And the wild beasts of the islands shall cry in their desolate houses, and dragons in their pleasant palaces: and her time is near to come, and her days shall not be prolonged.”  (King James Version of the Bible (KJV, 1611)).  In the Greek, the word was used also to mean "a deceitful woman" although etymologists note that may have been to suggest she was “a binder, an entangler”, the sense from seira (cord, rope).  In zoology, the mammalian sense appeared first in French in Les entretiens d'Ariste et d'Eugène (Conversations between Ariste & Eugène) by the French Jesuit priest Dominique Bouhours (1628–1702) while the use to describe the aquatic salamander was introduced in 1766 by Swedish zoologist & physician Carl Linnaeus (1707–1778 and styled as Carl von Linné after 1761) for a genus of reptiles.  In organic chemistry, scientists noted the attraction exerted by the sirens of mythology and coined “sirenin” to describe a sexual attraction pheromone in some fungi of the genus Allomyces.  Less charmingly, in early twentieth century Australian urban slang, a “stem siren” was a prostitute; in the Australian way, often it was clipped to “stem”.

The use to describe the mechanical device “making a warning sound” was first recorded in 1879 when they were installed on steamboats and this may have been imitative of the similar French word.  In the course of the twentieth century, the things were adapted as audible warning devices for many purposes including air raids, emergency service vehicles and fire alarms (now mandatory in residential accommodation in many jurisdictions).  In schools, workplaces and other geographically large sites, they were used to mark the start and finish of shifts, lessons, meal breaks etc.  The Elizabethan era (1558-1603) adjectives sirenean, sirenian, sirenic, sirenical & sireny) went extinct but as late as the 1940s, the spelling variation sireen still occasionally appeared and not always as a deliberate archaism.  The writer & critic John Ruskin (1819–1900 and known for his fondness for young. beautiful creatures), used the rare sirenic so with that imprimatur, some modern aesthete might be tempted to revive the form.  Siren is a noun & verb, sirenize is a verb, sirenlike, sirenless, sirenical & sirenic are adjectives; the noun plural is sirens or (the rare) sirenes.

Odysseus and the Sirens

In Greek mythology, the Sirens were sea demons, half-woman and half bird (although there were variants in the tales).  They were said to be the daughters of Achelous and either Melpomene, Sterope or Terpsichore, Phorcys often named as their father, while it was also related they were born of the blood of Achelous when he was wounded by Heracles. There were two Sirens in the Odyssey (Homer’s eighth century BC epic poem following the ten year trek of King Odysseus (Ulysses) returning to his home island Ithaca after the decade-long Trojan War) but in the works of later authors there could be four (more often three).  Historians attribute variations in the myths to (1) authorial innovation or (2) in an age of limited literacy, poetry spread in oral performance, meaning details could become blurred.  What was consistent was the musical virtuosity of the Sirens, a popular depiction of them as a three-piece ensemble, one playing the flute and one the lyre while another sang her songs.

Sirens and the Night (1865), oil on canvas by William Edward Frost (1810-1877).

The Sirens used their lyrical and earthly charms to lure sailors to their death; attracted by the enchanting music and voices, the seduced seafarers would sail their ships too close to the rocky coast of the nymphs' island and there be shipwrecked.  Not untypically for the myths of Antiquity, the Sirens are said to have had many homes.  The Romans said they lived on some small islands called Sirenum scopuli while later authors place them variously on the islands of Anthemoessa, on Cape Pelorum, on the islands of the Sirenuse, near Paestum, or in Capreae.  All were places with rocky coasts and tall cliffs and thus for ships potentially lethal places although the fate of sailors was more gruesome, the Sirens devouring them.  The Argonauts sailed close to the Sirens, but, using the same principle as “radio jamming” in the twentieth century, Orpheus sang as long as the crew was within earshot of them (“drowning out their signal”), so none were lured (except the unfortunate Butes, carried away by Aphrodite after he fell victim).

Temptress in Siren mode: Lindsay Lohan, First Point (2011).

It was Odysseus who most famously escaped the sirens.  Longing to hear their songs but, forewarned by Circe and having no wish to be shipwrecked and devoured, he had his sailors fill their ears with beeswax, rendering them deaf.  Then, he ordered he be tied to the mast, telling his crew that whatever he said, they were not to release him but instead tighten the knots, not cutting the bonds until the ship had sailed far from the coast.  Of course, approaching the rocks, he heard the lovely voices and implored the crew to release him but they followed their skipper’s orders, not setting him free until the danger had passed.  Some writers claimed the Sirens were doomed to die if a man heard their singing and escaped and, as Odysseus sailed off, they flung themselves into the waters and drowned but, among the myths, that was not always their fate.  The idea of the Sirens persists in idiomatic use: the term “siren sound” refers to words or something exerting a particularly compelling attraction but “siren song” or “siren call” can be used of something not directly audible, such as the thoughts evoked by a painting or even a concept; populism, fascism & communism have all been described thus.  That idiomatic use describes an enticing but dangerous appeal, especially a misleading one.

The Roman Poet Ovid (Publius Ovidius Naso; 43 BC–17 AD) wrote that the Sirens were once ordinary girls, companions of Persephone; in his telling they were something “nice girls from good families who got led astray by mixing with the wrong crowd”.  When Persephone was abducted by Pluto, they asked the gods for wings so they could soar in the skies to help them search for their lost companion; that’s the most romantic explanation for the “half-woman and half bird” motif.  More unforgiving writers attributed the transformation to (1) the anger felt by Demeter when the Sirens failed to prevent the abduction of her daughter or (2) the wrath of Aphrodite who sought to deprived them of their feminine beauty because they scorned the pleasures of love.  A twist on that was that after their transformation, they made the mistake of trying to rival the muses who avenged the slight by plucking the Sirens’ feathers.  In a literary sense, the nymphs certainly exerted on authors a siren call.  The tomb of the Siren Parthenope was said to be in Naples, where her body had been cast upon the shore and that geographical connection is in the narrative strand in which Parthenope was a hauntingly beautiful Phrygian girl who fell in love with Metiochus but could not bring herself to break her vow of chastity.  She cut off her hair and ran off into exile in Campania (close to Naples) where she dedicated herself to Dionysus, something possibly the origin of Aphrodite’s disapprobation; it was Aphrodite who turned Parthenope into a Siren as punishment for abandoning her love.  The Sirens were also said to sing for the blessed in the Islands of the Blessed; because they could play the celestial harmonies, they were often depicted on sarcophagi.

The Chrysler Air Raid Siren and the Firepower V8  

According to Guinness World Records, the loudest sirens ever were the 350-odd built in the early 1950s by Chrysler for the US government and installed around the country to warn of an impending nuclear attack by the Soviet Union.  The maximum volume the devices generated was recorded (at a distance of 100 feet (30.5 m)) as 138 dB (decibels), a level at which a human would suffer at least temporary deafness if within around 200 feet (60 m) during operation.  Guinness noted the compressor discharge throughput at peak volume was 74 m³ (2,610 cubic feet at 7 lb per square inch) of air per second and the physics of fluid dynamics (air a fluid in this context) was such this would have caused a sheet of paper in the path spontaneously to ignite.  By comparison the now retired SST (supersonic transport) airline Concorde at take-off produced noise levels between 112-114 dB at a distance of 100 feet and even afterburner equipped military jets (F-16, F-35 etc) haven’t been recorded as generating levels as high as 138 dB.

Although there were ebbs in the tensions, the “High Cold War” is defined usually as the time between the early 1950s and late 1960s, the public's fear of thermo-nuclear war at sometimes acute. In popular culture, the subject was a popular with authors and film-makers, the best known including the book On the Beach (1957) by Neville Shute (1899-1960) and the memorable film Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964), based on the novel Red Alert (1958) by Peter George (1924–1966).  The US government made many preparations for such an event, notably building vast underground facilities where essential personnel (members of the administration, the Congress, their families and servants) could live until it was safe for them to emerge into the post-apocalypse world and stake claim to whatever habitable real-estate remained.  The taxpayers who paid for these facilities were of course rather less protected but the government in 1952 did install warning sirens in cities; people might still be vaporized by comrade Stalin's (1878-1953; Soviet leader 1924-1953) H-Bombs but they would know what was coming so there was that.

US war-room film set for Stanley Kubrick's (1928-1999) film version of Dr Strangelove.  Upon becoming president in 1981, Ronald Reagan (1911-2004, POTUS 1981-1989) was reported as being disappointed nothing quite so dramatic actually existed, the White House's “Situation Room” something like what would be used by an insurance company to conduct sales training seminars.  The story is thought likely apocryphal but there is documentary evidence Mr Reagan did sometimes confuse historic fact with what he's seen in movies.

The early version of the warning siren was co-developed by Chrysler and Bell Labs and named CBVS (Chrysler Bell Victory Siren) which, given the consequences of nuclear war, seems at least optimistic.  Technically, although the acoustic properties met the specification, the drawback was the devices manually were activated and controlled, requiring someone physically to be on-location to start the thing and, being directional, rotate it so the sound would be broadcast 360^o.  The obvious flaw in that was, were  there to be a nuclear attack in the area, the job-description, at least potentially, was self-sacrificial, something comrade Stalin doubtless would have thought just the part of the cost of war with the unfortunate patriotic soul posthumously to be awarded the coveted Герой Советского Союза (Hero of the Soviet Union) decoration.  However, neither the White House or the Pentagon liked the optics and revised specifications for the sirens were issued.

Chrysler's engineers responded with a more elaborate device, automated and remotely administrated; because it was developed wholly in-house, the corporate-themed acronym CARS (Chrysler Air Raid Siren) was coined.  Introduced in 1952, the new design was powered by Chrysler’s new, 331 cubic inch (5.4 litre) Hemi-head V8, rated at what was then a stellar 180 HP (134 kW), a three-stage compressor added to increase output.  Instead of demanding a doomed operator, there was a control panel connected (with nothing more than the two-pair copper cables that became familiar as Cat3 “phone-wire”) to dedicated phone lines so it could be activated either by local civil defense authorities or the military.  The big V8 provided sufficient power to both increase the dB and the geographical coverage, the siren able to be heard over an area of some 15.8 square miles (41 km²), an impressive number given the electric sirens used today for tornado and tsunami warnings have an effective footprint of only some 3.9 square miles (10 km²).

In 1952, there was no engine better suited to the task than Chrysler’s new “FirePower” Hemi V8.  Applying their wartime experience building a number of high-output, multi-cylinder engines (the most remarkable a V16 aero-engine rendered obsolete by jet technology before it could be used), the FirePower featured hemispherical combustion chambers and was the corporation’s first use of OHV (overhead valves) in passenger vehicle engines.  Both OHV and hemispherical combustion chambers had been around for decades but, before long, Chrysler would make a (trade-marked) fetish of “Hemi”, continuing cheerfully to use the name for a range of V8s introduced in 2003 even though they no longer used a true hemi-head, the design unable to be adapted to meet modern exhaust emission laws.  The so-called “third generation” Hemi remains available still although how long it will last will be a matter of the interplay of politics and demand.  Doubtless, it’s on Greta Thunberg’s (b 2003) long (and expanding) hit-list and that she and the engine arrived on planet Earth in the same year won't much impress her.

Chrysler FirePower 392 cubic inch (6.4 litre) V8 in 1957 Chrysler 300C Convertible.  In the jargon, the pair of four barrel carburetors were dubbed  “dual quads”.

First sold in 1950, the FirePower appeared first as a 331, growing over the decade to 354 (5.8) and then 392 (6.4) before being retired in 1959, the wedge-headed alternative with increased displacement a cheaper path to power (the hemi heads needing special machining and the valve-train was heavy and labor-intensive to assemble).  Chrysler and Imperial shared the engines but remarkably, in an approach that would today shock accountants and efficiency experts, the companion divisions (De Soto & Dodge) produced nine different hemi-head V8s with capacities between 241 (4.0) and 345 (5.6) with relatively little commonality of components between them all.  The last of the FirePowers were noted also for being one of the first engines offered with electronic fuel injection (built with analogue components) but while that offered real advantages over the mechanical systems then available in a handful of models in Europe and the US, the technology was then too fragile to be reliable and most of the 16 sold (reputedly all but one) were recalled and retro-fitted with a pair of faithful four barrel carburetors.  In 1964, the hemi-head was revived for a racing engine and, to satisfy the regulatory body that had been unimpressed with the use of such a thing in a series for “stock” cars, it was made available to the public between 1966-1971, this time called “Street Hemi”.  In 426 cubic inch (7.0 litre) form, it gained a reputation Chrysler would exploit for decades after production ended.

Some 350 CARS were built, all by the Chrysler's M&I (Marine & Industrial Engine Division, based in Trenton, Michigan) with some maintained in service as late as the 1970s.  During the era of détente, the last were retired, some sold to museums or collectors while other were just abandoned because, mounted atop tall buildings to maximize their acoustic coverage, the cost of removal far exceeded their value as units to be re-purposed or scraped.  At least three fully functional CARS still exist, one in a remote part of Texas where it’s safe to stage the occasional demonstration of the sound.  During these displays, the clear zone (minimum safe distance) extends outwards 320 feet (97.5 metres) but even at this range, anyone standing directly in front of the projection horns would find the experience uncomfortable, prolonged exposure risking some damage to the eardrums.  Although directional, there’s much “sound soak” in the device's proximity so just operating the siren from the side control panel requires hearing protection (acoustic earmuffs rated at a minimum 30 dB).

CARS at the Don Garlits Museum of Drag Racing, re-awakened after decades, 1997.

One collector attracted to them was Don Garlits (b 1932) who, in the post-war years, was among the most innovative and successful drivers and builders in the then wildly popular sport of drag-racing and it was with highly-modified Chrysler Hemis (the HP (horsepower) of which would come to be generated in thousands) he built his reputation.  In 1997, a documentary crew from the UK visited Garlits and saw one of the old CARS sitting neglected in the storeroom where it’d sat for decades after having spent some 20 years in salt-laden air atop a Florida high-rise.  Remarkably, after doing little more than connecting a battery and checking the oil and coolant, once a carburetor had been bolted on with a can of gas (petrol) rigged up, it started almost immediately, a reasonable achievement given it had never before run on gasoline because the CARS always used propane.  As Garlits over the decades had discovered a ¼ mile (402 metres) at a time, the FirePower Hemi was a tough old thing.

The Siren Suit

Weldon pattern for siren suit, 1940.  Home-made clothes used to be common and wartime conditions made the practice spike.  The production and distribution of patterns was a significant industry, enduring, at a smaller scale, to this day.

Unrelated to the seductive Sirens of mythology, the “siren suit” was a World War II (1939-1945) era coining describing a garment “ideal to wear when there was a risk of an air-raid siren sounding”.  The design wasn’t new; they would have been familiar to previous generations as the “overalls” mechanics and such wore to protect their clothing from oil and dirt, the novelty being the application.  Because “the Blitz” (the bombing campaign against London and other English cities waged by the Luftwaffe (the German Air Force) in 1940-1941) was conducted at night, that meant air-raid sirens were most likely to sound when people were in bed and the attraction of the “overall-like” siren suit was it could be worn over nightwear (pyjamas, nighties and such), meaning that upon being wakened by the siren, time would not be wasted getting dressed before rushing off to seek shelter; all one need to put on was one’s shoes.  With wool, silk & cotton supplies being diverted to military production, recycled blends using the more available rayon came increasingly to be used and the versatility of the synthetic made it popular; available in a variety of weights, unlike fabrics made from natural fibres, it was not subject to creasing or shrinkage.  In 1940, the most commonly requested feature was a “hood” and these came to be included on many, often with a lining for additional warmth.  Stylistically and conceptually, the siren suit can thus be imagined as a “proto-onesie”, one of the twenty-first century’s more controversial garments, not so much for what is it (warm, comfortable, convenient) but for where some choose to frequent while wearing one (Walmart, fast food outlets and such).

Wartime individualism, circa 1941: Despite wartime privations, fashion sense didn’t die and ways were found to individualize even the most starkly functional items.

As this publicity shot indicates, gas-masks were in the UK of 1940 a piece of compulsory kit for civilians, the use of poison gas expected by many in politics and the military.  Ironically, of all the leaders in the era, it was only Winston Churchill (1875-1965; UK prime-minister 1940-1945 & 1951-1955) who was enthusiastic about the use of gas as a weapon, thinking it ideal to deploy on beaches in the event of an amphibious assault by the Wehrmacht (the German military (1935-1945)).  Even Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) explicitly ruled out the use of poison gas, despite the Germans also holding large stocks.  Although in 1918 Hitler had learned of Germany’s capitulation when in hospital recovering from the temporary blindness suffered after being gassed, his unwillingness to use gas was not a humanitarian gesture but because the unpredictability of the wind (in Europe the “westerly” (ie from west to east) the prevailing type) made use too risky.

As a unisexual style, by 1940, the siren suit wouldn’t have been too shocking a challenge to the fashion police.  Although the tradition is longer still, in the West, women routinely (if not universally) had been wearing “trousers” since the mid-nineteenth century (for sport, work & leisure, the light and convenient “pyjama-suit” welcomed by many) and, during World War I (1914-1918), as in increasing numbers they entered the industrial workforce to replace men conscripted for military service, the sheer functionality of trousers was compelling (and often, for safety reasons, compulsory); women in overalls became commonplace.  Given the purpose, the early siren suits (the less pleasing “blitz suit” never catching on) were designed with little in mind except comfort, warmth and speed in donning so most were fastened with a zip though the photographic record confirms buttons or snap-fittings were also used, mass-production made immediately possible because they could be sewed on the same lines used to make overalls.  Winston Churchill often was photographed in his siren suit and while that promoted use, it also confirmed the style was not “slimming”.  Even more than overalls, siren suits seem to have featured generously-sized pockets, a thoughtful addition permitting those disturbed from their slumber quickly to stash valuables and the essentials needed for a few hours in an air-raid shelter while retaining the recommended “hands-free” status.  Coincidentally, the siren suit fitted in with the wartime “fashion zeitgeist” the rationing of fabrics and other materials imposing on clothing simplicity and a reduction in bulk.  Even after that economic imperative had faded, that simplicity would remain influential in the post-war years, most obviously in the minimalist movement, effects achieved with severe cuts rather than fussy embellishments.

The prime minister had earlier worn the same Siren suit on a visit to the White House to meet Franklin Delano Roosevelt (FDR, 1882–1945, POTUS 1933-1945) and it was much admired, the FLOTUS (Eleanor Roosevelt (1884–1962; FLOTUS 1933-1945) even saying she’d like to have one made for her husband, if “…the wool shortage” would allow it.  Decades later, during his visit to Washington DC, Volodymyr Zelenskyy (b 1978, President of Ukraine since 2019) found his similar sartorial choice not as well-received.  According to Churchill, even before the war he’d been inspired by the “coveralls” worn by coal miners to commission the London tailors Turnbull & Asser to create a bespoke one for him, finding it just the thing to wear when enjoying his hobby of painting.  Upon the country being threatened by bombing, he ordered several, his specifications recorded in the company’s archives: “Generously cut, with two breast pockets, a zip fastening, roomy side pockets, a belt and pleats to the front of the trousers.”  To suit their client’s whims, Turnbull & Asser made them in various fabrics including the same pinstripe as some of his suits, a durable serge twill and one in a velvet of striking emerald green, still on display in their London store.  There’s nothing to suggest he ever worn one made from utilitarian rayon.

Skeg

Skeg (pronounced skeg)

(1) In shipbuilding, a fin-like projection sometimes 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 GM (General Motors) stylists, a “lower fin”, matching the, seen in embryonic form on the 1959 Pontiac and used on certain 1961 Oldsmobiles and the 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 some 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).  In English slang, skeggy is (1) the coastal Lincolnshire town of Skegness or (2) an inhabitant of Skegness.  The name of the 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 Faroese skegg (to jump, skip, move, hurry (and source of the given name "Skeggi")) is thought unlikely.  Skeg is a noun and skegged is an adjective; the noun plural is skegs.

The skegs of nautical architecture should not be confused with the homophone Sceggs, the acronym for students of S.C.E.G.G.S. (Sydney Church of England Girls Grammar School), seen also in the adjectival forms sceggesque & sceggish (one whose style suggests something similar to the stereotypical student of the school); Those adjectives exist because Scegg is also "a look" and there are students from schools other than S.C.E.G.G.S so described, often in the form "she's such a scegg".

On nautical vessels, skegs where they exist fulfil 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 most 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 par of their shafts inside skegs while others encased all.  Although the traditional design imperatives were shared with other ships, for navies, they 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 added 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 (Iowa, New Jersey, Missouri & Wisconsin, launched 1943-1944 and in commission variously until in 1992 the last was struck the Naval Vessel Register) 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; the skegs compensated for this, offering a hull with similar rigidity.

The US Navy’s South Dakota class battleships (South Dakota, Indiana, Massachusetts & Alabama, launched 1941-1942 and in commission 1942-1947) 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 stern's abrupt end.

However, advantages in engineering and metallurgy meant much of the functionality afforded by skegs came to be achieved in other ways so 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, making skegs 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.

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 about a half-inch (12 mm) more vertiginous.  The attractions of the style however were fading and from 1960, GM began to tone things down, Chrysler following the lead (Ford and AMC (American Motors Corporation) never really got involved in the big fin business).  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.

An inspiration, a step in the evolution and the result: A captured German V2 rocket (1945, left), a full-size clay mock up of a design proposal for the 1961 Cadillac (1958, centre) and 1961 Cadillac Coupe de Ville convertible (left).  The V2 is on display at the Australian War Museum, Canberra, Australia and the clay mock-up Cadillac was photographed at the General Motors Technical Center, Warren, Michigan.

For the 1961 range, Cadillac further pruned the fins but as compensation, the design staff added a "lower fin" and these, informally, they called “skegs”.  While in a sense just another of the era's many extravagances, the outgrowths could have been part of something even stranger because among the design proposals which emerged from the GMADS (GM 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, what was proposed by the ADS may have had something to commend it and certainly, such was the placement and size of the fins they'd have in some way interacted with the air-flow.  Whether the design was ever subjected to wind-tunnel testing (this was years before computers could emulate such research) isn't know but the look was sufficiently favored for an expensive, full-sized clay model to be rendered.  Ultimately the longer, though perhaps more restrained, skegs seen on the 1961 & 1962 cars were preferred.

1959 Buick Invicta Concept.

Detroit's stylists in the 1950s not only sketched a car with a big dorsal fin but authorization was granted to build one to test public reaction.  There was a precedent for the "third fin" because the Czech manufacturer Tatra had for years used them (out of necessity) and they'd provided essential stability for many LSR (land speed record) vehicles.  The Invicta concept didn't proceed to production.

Those who think Detroit's cars of the late 1950s & early 1960s were sometimes bizarre should look at the design proposals that were rejected.  Despite the clear exuberance in the the imagination, there's never been anything to suggest the stylists were stimulated by anything stronger than an after work martini.  Compared with some of the clay mock-ups, what emerged from the production lines hinted at rather than emulated missiles but should it be thought what was rendered in clay was wild, the archives of the GMTC (GM Technical Center) contain a wealth of sketches of truly bizarre design studies which didn't make the cut to reach the hands of the modelers.  Presumably, those sketches which survive are those the stylists thought deserved to be remembered and there must of been those which even the designer concluded needed to be shredded.  As the archives also demonstrate, those who criticize the fins and "bullet" taillights on the 1959 Cadillac have reasons to be grateful even stranger things were rejected.

Cadillac’s “skeg years”: 1961 (left) and 1962 (right).  There was a time when this sort of thing was just a fork of Detroit's design orthodoxy. "The past is a foreign country: they do things differently there."

It was an era of annual styling changes and switching the orientation of taillights from the horizontal to vertical was typical of what stylists each season did to “refresh” the line, a process which came to be known as “facelifting” (ie a figurative use from cosmetic plastic surgery: altering the appearance while retaining the underlying structure).  Although this basic body would have a four-year life (1961-1964), the abandonment of the skegs for its final two seasons was, by facelift standards, a quite major update, one prompted by a change at the top of GM’s design’s studios.  Also of note is the roofline on the 1961 Cadillac four-window Sedan DeVille ((Body Style 6239, top left) which used an implementation of GM’s so-called “flat-top”.

1959 Chevrolet Impala Sport Sedan (Flat Top).  This was the year of the "bat-wings" and "cats eyes" taillights.

Along with the contemporary “bubbletop”, in its pure form, GM’s flat-top lasted only two seasons (1959-1960) but the two are now Detroit’s most admired rooflines of the post-war years.  The “bubbletop” was a direct tribute to fighter aircraft but the flat-top (it was also dubbed “Flying Wing” but GM internally referred to the blade-like structure as the “cantilevered top configuration”) was mid-century modernism.  Available exclusively on the four-door hardtops, each GM division (Chevrolet, Buick, Oldsmobile, Pontiac & Cadillac) offered the dramatic look (production-line rationalization made economically viable by all five sharing a single, core structure) although there were several designations.

1959 Cadillac Four Window Sedan (upper) and 1959 Pontiac Vista (lower).

Up-market Buick (Four-Door Hardtop), and Cadillac (Four Window Sedan) weren’t very imaginative while Chevrolet and Oldsmobile choose Sport Sedan; only Pontiac showed much imagination in picking Vista, an allusion to the unusually good 360^o visibility the style afforded (although the curves in the glass did produce some distortions).  Shamelessly, even after ceasing to offer flat-tops, Pontiac continued to use the Vista name.  Cadillac’s final flat-top fling came in 1961 with a modified version using less rear overhang but the market impact was muted, the more conventional six-window four-door outselling it by more than five-to-one margin as preferences shifted towards for formal lines.  However, the look didn’t at once die because it lingered on the four-door Chevrolet Corvair until 1965 and between 1962–1978 the motif appeared on the Alfa Romeo Giulia.

Cadillac’s take on the “long & slightly less long” of it: 1961 Cadillac Six Window Sedan de Ville (Body Style 6329L, left) and 1961 Cadillac Town Sedan (Body Style 6399C, right).  In the brochures, the terms “Town Sedan” and “Short Deck” both were used.

One quirk of Cadillac’s brief embrace of the skeg was there were two iterations: skeg long and skeg short.  Whether in response to dealer feedback 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 (as the “Town Sedan”), an encouraging 3,756 were built so the option was in 1962 offered on the four-window de Ville Sedan (Body Style 6398 and now called “Park Avenue”) but sales dropped to 2600.  The coming of the 1963 models marked the retirement of the short-lived skegs which thus ended their brief moment as something decorative although they continued the functional role in marine architecture.

1963 Cadillac Four-Window Sedan de Ville (Body Style 6239, left) and 1963 Cadillac Sedan de Ville Park Avenue (Body Style 6398, right).

Although smaller cars were selling well in other market sectors, among Cadillac buyers, the decline of interest in anything smaller was confirmed in 1963 when only 1575 of the Park Avenues were sold.  The 129.5 inch (3289 mm) wheelbase was common to the whole Sedan de Ville range but the “short deck” models were shorter by 7 inches (178 mm) for the first two seasons and an even more obvious 8 inches (203 mm) in 1963.  Space utilization was obviously a little better but the market had spoken; fewer than 8,000 of the short-deck models sold while the standard editions shipped in the tens of thousands, the flirtation with (slightly) more efficient packaging abandoned for 1964; in the course of the following decade, the Sedan de Ville would grow another seven inches (178 mm) and gain over 400 lb (181 kg).  It should be noted that by international standards, the truck capacity of even the abbreviated models was still quite generous, able effortlessly to accommodate two sets of golf clubs, something which later became something of a de-facto standard used in assessing the practicality of sports cars.  Jaguar used this feature as a selling point when the XK8 (1996-2006) was introduced because it wasn’t possible with all versions of the old E-Type (1961-1974).

1958 Cadillac Series 62 : Extended Length Sedan (Body Style 6239EDX, left) and the standard Sedan (Body Style 6239, right).

There was in the early 1960s much criticism that “full-size” US cars had become too big but the “short deck” venture was a departure for Cadillac which had for some years been making things bigger and in 1958 the company had even included the “Series 62 Extended Length Sedan”.  The Series 62 Sedan was already an impressive 216.8 inches (5.5 m) long but the Extended Length version measured an even more imposing 225.3 (5.7), the additional 8.5 inches (216 mm) all in the rear deck, creating a more capacious trunk (boot).  Whether buyers just liked the look or there really were a lot of them with much luggage, the elongated sedan sold well, some one in five of the sedans having the big trunk and there was of course a healthy industry in jokes about Mafia functionaries and other figures in organized crime grateful finally to have more space to transport the corpses.  Surprisingly perhaps, despite mafia hit men contributing to to sales numbers of 20,952 of the 103,455 (excluding Eldorados and “chassis only” sales) Series 62s produced in 1958 (some 20%), the Extended Length Sedan proved a single-season one-off.

For 1963, the short-deck models might have re-appeared for another dismal season but the skegs were abandoned, never to return.  The fins 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 they were vestigial, a hint which for decades would be retained.

1961 Oldsmobile Super 88.  The rear skegs were thought necessary to offset the “pointed-look” of the fenders and the front ones (the closest equivalent in nautical use being hydrofoils) were there just so the front bumper matched the lines of the rear, emulating Pontiac’s approach in 1959.

Within GM, the skegs were not exclusive to Cadillac, appearing also on the 1961 full-sized Oldsmobile 88 & 98 although the motivation of the designers differed.  What Cadillac in 1961-1962 did was nothing more than a styling gimmick, concocted at a time when it was obvious the moment of the big fins was passing but the motif still exerted such a pull that they were re-interpreted on the path to extinction.  In the Oldsmobile design office, the skeg had a different purpose, the protrusions deemed necessary as a device to counterbalance the rearward point of the quarter panel that terminated in a “cigar-shape”.  Mercedes-Benz had used a (more conventional) variation of the idea of a “balancing appendage” when in 1957 the 300d (W189, 1957-1962) appeared with rear fenders enlarged and re-shaped to disguise the pre-war style of the coachwork used on the W186 (300, 300b & 300c; 1951-1957) which came to be referred to as the "Adenauer" because several were used as state cars by Konrad Adenauer (1876–1967; chancellor of the FRG (Bundesrepublik Deutschland (Federal Republic of Germany; the old West Germany, 1949-1990).

1969 Alfa Romeo Spider (Duetto).

Interesting, between 1966-1969, the Alfa Romeo Spider (Type 105/155 and known informally known as the Duetto) featured the memorable Osso di Seppia (round-tail, literally “cuttlefish”) coachwork which resembled what Oldsmobile did in 1961.  After 1970 and until the end of production in 1994, the Spider used variants of the Kamm tail which increased luggage capacity and presumably also conferred some aerodynamic advantage.  A professional designer could write a long, learned essay explaining why the later Kamm tail was a more accomplished achievement which avoided the Osso di Seppia's flaws but in the collector market it's the cigar-shaped original the purists covet.  Had the Italians added skegs as Oldsmobile did, they’d have had more about which to complain.

1959 Pontiac Bonneville Convertible.  In 1959 Pontiac’s big news was the “split grill” which would for decades be a brand signature and the five inch (125 mm) increase in the track, lending the division that year’s most memorable slogan: “Year of the Wide Track”.  Given all that, the modest skegs weren’t much noticed, especially because, at the rear, eyes were drawn to the pair of small blades adorning the upper surface.  The idea was first seen on the 1953 Chevrolet Corvette (where they’d appeared on the taillight nacelles (pods)) and although often referred to as “finettes”, in the documents of the GM Design Studio they were “taillight bezels” or “ornamental finlets”.

1959 Pontiacs: Bonneville (left) and Catalina (right).

The skegs were less noticeably skeggish than the later implementations by Oldsmobile and Cadillac because they were smaller and, at the rear, installed in the horizontal rather than the acute angle which made them so obvious on Cadillacs.  At the front, the angle was less than adopted by Oldsmobile.  Pontiac also used the “long rear deck” as a marker of a model’s place in the hierarchy, the Bonneville at 220.7 in (5,606 mm) in length being seven inches longer than the lower-priced Catalina at 213.7 in (5,428 mm).  While two inches (25 mm) of the difference was absorbed by the Bonneville’s longer wheelbase (124 in (3,150 mm) vs 122 inches (3,099 mm), the remaining bulk was found in eth rear deck.  However, unlike the Cadillacs, there were no “short & long skegs”, the bumpers of both Pontiacs being identical although there were other markers of “pricetaggery”, the Bonneville’s elliptical taillights noticeably elongated.

1955 Ford La Tosca.

A half-decade before Cadillac decided their customers needed skegs, Detroit had pondered the idea.  Shown in 1955, Ford’s La Tosca (named apparently after Giacomo Puccini’s (1858–1924) three act opera Tosca (1900) although the intended connection seems to have been a general sense of the “emotional and dramatic” rather than the fate of the doomed protagonist) was unusual in that it appeared not as a full-scale “concept car” but in the form of a ⅜ scale model, used to demonstrate the possibilities offered by a remote-controlled chassis, directed through the medium of radio waves.  To achieve this, rather than build custom components (as the Pentagon would have done), Ford’s engineers dipped into the corporate parts bin and wired together the regulator and relay from a power window apparatus, the electric motor used to lower a convertible’s soft-top, a power seat mechanism and a standard, 12 volt car battery.  The system worked flawlessly and, depending on the topography, La Tosca could remotely be controlled at distances greater than a mile (1.6 km).  According to Ford records, the project began simply as an “…internal exercise to show students in the Advanced Studio how hard it was, even for professional designers, to design a car” but so long did the model take to complete (the complex curves and canted structures challenging to render in what was then the still novel fibreglass) that “mission creep” intruded, thus the radio-controlled chassis.

1954 Lincoln Futura (1954) and Ford Mystere (1955).  In Detroit, these were at the time typical of what was authorized to be built as "concept cars", machines destined for the show circuit to gauge public reaction.  If they now seem rather wild, much of what never left the stylists' (they weren't yet "designers") sketch pads and drawing boards truly was bizarre.  

Stylistically, La Tosca was in the vein of the corporation’s other concept vehicles of the era such as the Lincoln Futura (1954) and Ford Mystere (1955), the trio reflecting the way the industry was applying motifs from missiles and jet-propelled aircraft such as Perspex bubble-tops, tubes, fins and exhaust nacelles.  Most of these proved to be brief, though memorable, fads of jet-age aesthetics although elements were easily recognizable in the 1958 Lincoln and GM of course would later take up the skegs.  The remote-control concept was ahead of its time though it did find a niche in model cars and aircraft.  In the twenty-first century, new versions of the technology are now mainstream with cranes, trucks and trains routinely operated from sometimes thousands of miles away although usually on mine-sites and other remote locations (experiments with vehicles on public roads are being undertaken).  Despite these advances, the industry regards the technology as transitional and intends as soon as practicable to remove the human (and thus costly and unreliable) element completely, re-allocating control to an entirely autonomous AI (artificial intelligence) model which, without complaint or toilet breaks, can be worked 24/7/365.
