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.

Cadillac’s Skegs, 1961-1962

Cadillac Coupe DeVille: 1959 convertible (left) & 1960 hardtop (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 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.

Heckflosse

Heckflosse (pronounced hek-flos or hek-floss-ah (German))

A nickname for the Mercedes-Benz W111 & W112 sedans produced between 1959-1968 (1961-1971 for the coupés and cabriolets with the pruned fins) and translated in English as fintail ("finnie" the affectionate diminutive).

1959: A compound word in modern German, Heck (rear; back) + Flosse (fin).  As a surname, Heck (most common in southern Germany and the Rhineland) came from the Middle High German hecke or hegge (hedge), the origin probably as a topographic name for someone who lived near a hedge.  The link with hedges as a means of dividing properties led in the Middle Low German to heck meaning “wooden fencing” under the influence of the Old Saxon hekki, from the Proto-West Germanic hakkju.  In nautical slang heck came to refer to the “back of a ship” because the position of the helmsman in the stern was enclosed by such a fence and from here it evolved in modern German generally to refer to "back or rear".  Flosse is obscure but was probably related to the Middle English and Old English finn, the Dutch vin, the Low German finne and the Swedish fena.  Because all German nouns are capitalized, Heckflosse is correct but in English, where it's treated as a nickname, heckflosse is common.  Heckflosse is a noun; the noun plural is Heckflossen (although it has in English texts appeared as Heckflosses).

Chrysler in 1957 really did claim their tail-fins were not mere decorations but "stabilizers" designed to move the centre of pressure rearward.  Although designed during Detroit’s tail-fin craze during the mid-late 1950s, Mercedes-Benz always claimed the Heckflosse (tail-fins), introduced in 1959, weren’t mere stylistic flourishes but rather Peilstege (parking aids or sight-lines (literally "bearing bars")), the construct being peil-, from peilen (take a bearing; find the direction) + Steg (bar) which marked the extent of the bodywork, this to assist while reversing.  It's never been clear if this interpretation existed during the design process or was applied retrospectively in response to criticism after the debut but by 1960, even in the US where the things has assumed absurd proportions, the fin-fad was fast fading.  As a cultural artefact, the distinctiveness of the Heckflosse made them a staple for film-makers crafting the verisimilitude of the 1960s High Cold War, just as the big 600s (W100, 1963-1981) from the same era are used still when wealth or evil (not always synonymous) needs to be conveyed.

1963 Mercedes-Benz 300 SE Lang (Long) (W112).

Although on a longer wheelbase than the standard 300 SE, the model designation remained the same, the SEL nomenclature not appearing until the subsequent (W109) 300 SEL (1965).  The additional framing around the badge appeared only on some early-build models and was a unique embellishment although the 300 SE, by German standards "dripped with chrome".  The chrome trim attached to the tail-fins on the 300 SE and the most expensive of the W111 range (220 S & fuel-injected 220 SE) wasn't fitted to the 220 or the cheaper W110 models and in a quirk of production-line economics, it transpired it was more expensive (ie labor intensive) not to fit the trim because of the additional finishing required.  The alpha-numeric soup of model designations which proliferated from the late 1960s started as something almost logical (ie a 300 used a 3.0 litre engine, a 220 a 2.2 etc) but as new product lines emerged, anomalies increased until, in the early 1990s, it was re-organized although the new system would generate its own inconsistencies and eventually the number often had only a vague relationship with engine displacement.

Heckflosse assembly line, Stuttgart, Germany, 1962.

The Heckflosse was one of the first cars to include in its design the concept of the “safety cell”, a passenger compartment designed to protect the occupants in the case of impacts or roll-overs, the structures to the front and rear (ie the engine bay and luggage compartment) essentially “sacrificial”.  This idea was the ancestor of the modern “crumple zone” in which the front and rear compartments were designed to deform upon impact rather than retaining structural integrity, the object being to absorb and dissipate the energy generated in a crash, preventing it reaching the passengers.  The concept was not new, having for generations been a part of naval architecture, warships using what designers dubbed the “armored citadel”: a kind of “box” containing the vital machinery and magazine (ammunition), the structure created by the armoured deck, waterline belt, and the transverse bulkheads.  While this design didn’t make warships “unsinkable”, it did make them harder to sink and there have been ships which have had their whole bow & stern blown off yet have remained afloat, able to be towed back to port.

The car is a 230 S, one of the later-build Heckflosses.  In 1965, shortly after the release of the W108 (as the 250 S & 250 SE) with a new (almost finless) body, the 230 S was created as a lower-cost six-cylinder model, using a detuned variant of the 2.3 litre engine introduced with the 230 SL (the original “pagoda”, 1963-1971) and fitted with twin carburetors rather than the roadster’s fuel injection.  Other than the larger engine, the 230 S substantially was identical to the 220 S but unexpected was the later augmentation of the Heckfosse range with the 230, created by installing a single carburetor version of the 2.3 litre unit into the “short-nosed” W110 body with simplified trim and interior appointments; the W110 previously had been available only in four-cylinder form (gas (petrol) & diesel); in that it was a similar concept to the earlier W105 219 (a model discontinued after German authorities designated it a “tax-dodge” and closed the loophole.  In 1966 the 230 was upgraded to used the twin carburetor engine of the 230 S but was left unchanged in other aspects and with the debut of the smaller W114 & W115 models in 1968, Heckflosse production ended.

Located in the affluent neighborhood Jamaica Estates in the Queens borough of New York City, the mock-Tudor style house was built in 1940 by the president’s father (Real estate developer Fred Trump (1905–1999)), Donald Trump living there for his first four years of before the family moved into something larger in nearby Midland Parkway; Mr Trump has been “up-sizing” ever since.  In an indication of the power of the “Trump brand”, the house in July 2026 sold for US$2.14 million, a useful premium above the valuation of “about a million” property analysts suggests might been achieved without the celebrity association.  However, since being bought in March 2025 for US$835,000, a claimed half-million odd had been spent on “renovations and remodelling” the project going “over-budget” because of a “higher than expected spending on a new HVAC (heating, ventilation & air-conditioning) system and the property's garden”.  Still, the flip appears to have booked a profit well over US$750K and, as Donald Trump’s boyhood home, it may well become an official historic site (although for real estate that can be a double-edged sword).

1957 Ford Thunderbird and 1959 Auto Union 1000 SP.

Fin-wise, the closest comparison to the Heckflosse was probably the 1957 Ford Thunderbird which, compared with what Chrysler and General Motors (GM) were doing at the time, was quite restrained.  Genuinely, the fins on the first generation Thunderbird (1955-1957) were functional as Peilstege.  In production between 1958-1965 and unashamedly a "scaled-down" borrowing of the Thunderbird's lines, the Auto Union 1000 SP may be the most successful of the many attempts to produce a "smaller version" of an admired model; indeed, many professional stylists went on record rating the German car a more accomplished interpretation of the design elements ("down-scaling" often has resulted in some awkwardness, witness the Triumph Mayflower (1949-1953)).  While the visual clues translated directly, the 1000 SP was built only with a 981 cm³ (60 cubic inch) 3-cylinder two stroke engine while Thunderbirds during the Auto Union's existence had V8s as big as 7.0 litres (430 cubic inch).  Being a two stroke, the 55 HP under the 1000 SP's hood (bonnet) were very busy while the Thunderbirds just wafted along. 

On 1 October 1966, Heckflosses were part of the small motorcade in which, having served the twenty year sentences they were lucky to receive from the International Military Tribunal (IMT) at the first Nuremberg Trial (1945-1946), war criminals Albert Speer (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945) and Baldur von Schirach (1907-1974; head of the Hitlerjugend (Hitler Youth) 1931-1940 & Gauleiter (district party leader) and Reichsstatthalter (Governor) of Vienna 1940-1945) were driven from Spandau prison in Berlin.  The next day, Speer he boarded a Pan-Am Boeing 727 for a flight to Hanover, his first time on a jet aircraft because in 1945 permission had been denied (ostensibly on security grounds) for him to go on a test flight in one of the two-seater Messerschmitt Me-262s built for pilot-training.  Like many aspects of his life after release, the THF-HAJ flight had been planned while in Spandau, Speer particularly taken with the 727 because he'd so often seen one during its final descent while tending the prison grounds he'd transformed into a landscaped park.

1971 Mercedes-Benz 280 SE 3.5 Coupé (1969-1971).

On the sedans, the uncharacteristic exuberances were left undisturbed until production ended in 1968 although after 1965, the range was restricted to a line of lower cost, utilitarian models.  The coupé and cabriolet went on sale in 1961 and lasted a decade; truncating the Heckflosse, they achieved an elegance of line Mercedes-Benz has never since matched but then, few have.  Students of the German language can decide whether a de-finned two-door is a gestutzte Heckflosse (pruned Heckflosse) or a gerupfte Heckflosse (plucked Heckflosse)

1969 Mercedes-Benz 300 SEL 6.3 (W109, 1968-1972).

By 1965, on the W108 and W109 (1965-1972 and which replaced the more expensive W111 models & all the W112 sedans), the fins, though barely discernible, still existed, the factory noting the contribution to structural rigidity, adding strength without the increase in weight the use of other techniques would have imposed.

1978 Mercedes-Benz 450 SLC 5.0 (C107, 1977-1981).

Advances in metallurgy and engineering meant achieving the required strength became possible even without additional curvature in the metal and in 1971 the R107 (roadster 1971-1989) and C107 (coupé 1971-1981) debuted with the rear surface an uninterrupted flat plane.

1978 Mercedes-Benz 450 SEL 6.9 (V116, 1975-1980).

Despite that, a year later, the W116 sedans (1972-1980) were released with the most vestigial of fins.  The retention of styling elements between generations is not unusual, the second generation Range Rover reprising the earlier model’s distinctive hood creases, even though no longer a structural necessity.  Because there was uncertainty around whether US regulators would outlaw convertibles, no coupé or cabriolet version of the W116 was developed which is why a LWB (long wheelbase) coupé version of the R107 SL was released (as the C107 SLC) and the R107 lasted an impressive 18 years, not replaced until 1989.

The factory’s claim the fins were Peilstege rather than “fashionable styling” was in 1959 at least plausible because, when the W111 was released, in the press kits there were many details of the emphasis on safety including features such as the “safety cell”, “crumple zones” and door-locking mechanisms designed cognizant of the results of “crash-testing”.  Providing drivers with a simple means to determine the point of the rear extremities was part of that vibe.  However, even in 1959 it was clear the fins were becoming passé and at the first opportunity (the W111 coupé first shown in 1960) the studio pruned them to the point they could no longer be said to be “parking aids” which does reinforce the suspicion the modest protrusions might after all been a slavish following of fashion.  The sketches in the company’s archives do support that, several conceptual sketches of the two-door W111 & W112 showing not only the fins but also “dog-leg” windscreen pillars, another motif from Detroit the Americans shortly would abandon.  Few doubt the factory made the right decisions in the final “pruned” form but the idea of a “Heckflosse Coupé” did intrigue some and at least one has been constructed.

1954 Chevrolet Corvette.

Mercedes-Benz in the late 1950s of course never was tempted to follow the lead of GM and Chrysler (Ford never really got involved) in making the W111's tailfins (whether they were really there to help when parking or were merely thought fashionable) truly macropterous but that doesn't mean Detroit didn't influence things because the Americans also did some small, "Heckflossesque" fins and one intriguing element on the original Chevrolet Corvette was the use of protrusions to house the taillights.  When in 1953 the Corvette was released, the fins with which US cars of the era were to become so associated had been around for a few year but hadn’t yet grown (variously upwards & outwards) to the absurd proportions they would later assume and there was nothing unusual in taillights being housed in some construction integrated with the bodywork; once just “bolted-on” lens, taillights had become a design element.  What appeared on the early Corvettes are not really fins and are most analogous with the streamlined nacelles which appeared on contemporary aircraft as enclosures for jet engines; that aspect of aviation architecture would for years be a popular motif for the taillight stylists (by then a highly valued member of the team).  Despite that, the accepted term describing the sculptural extensions is “taillight pod”.  Interestingly, in some of the internal corporate memos the term “nacelle” was used but “pod” became the accepted standard.

Beginning of the brief "four finlets" trend: 1954 Corvette (left) and 1953 Fiat 8V Supersonic (right).

The pair of small blades adorning the upper surface (although sometimes referred to as “finettes”) were in the documents of the GM Design Studio called “taillight bezels” or “ornamental finlets” and, modest as they were, the C1 Corvette was among the first production cars with “four fins” (the feature in 1953 also appearing on some examples of the exquisite Fiat 8V (1952-1954)), most manufacturers tending to fit them in pairs although, as a piece of biomimicry of aquatic species, some of the memorable inter-war and early post-war Tatras from Czechoslovakia had a single "central fin" running downwards from the rear of the roof.  The Tatra's fin (the concept familiar from LSR (Land Speed Record) machines) was there to enhance straight line stability and it was needed because of the car's configuration (advanced aerodynamics, a rear-mounted V8 engine and swing axles).  The fin did what it said on the tin but did little to alter the handling characteristics which, by virtue of the mechanical layout, could in unskilled hands be challenging.  The Corvette's behavior was more predictable but that didn't apply to the stylists (they weren't yet "designers") at GM and Chrysler who embarked on a process of “finflation” from which, mercifully, Chevrolet's sports car was spared.  Those on the early Corvettes were at least in a similar aspect ratio to those which appeared on actual jet engine nacelles where they were used to direct airflow in the desired direction and there would have been a slight aerodynamic effect (for better or worse) but the finlets were essentially decorative as GM’s memos indicated and similar additions even appeared on some dagmars (such as the 1954 Buicks).  The Corvette’s designers clearly though the moment had passed for when the restyled 1956 range was released, the pods had been banished, never again to be seen on the sports car.

1959 Pontiac Bonneville Convertible (left) and 1959 Pontiac Catalina Convertible (right).  Pontiac used the elongation of the elliptical taillights as a marker of a model's place in the division's hierarchy.

On the Corvette, the “taillight pod” and “ornamental finlets” combo didn’t make it into the 1956 range but the idea clearly became lodged somewhere in the GM collective memory because, on a grander scale, both were reprised on the 1959 Pontiacs; longer, higher and wider than the 1953 original, the look might have attracted more publicity had GM’s take on fins that year not been dominated by the Cadillac with the “twin bullet taillights” and the Chevrolet’s “bat wings”.  Compared with those extravagances, what Pontiac did was almost subtle and anyway overshadowed by two of the division’s more enduring debuts, the “split grill” and “year of the wide-track” campaign, the former coming and going, the latter lasting for more than a decade.  In a harbinger of what was to come (and ultimately doom Pontiac), all five GM divisions built their cars using the single platform of the GM B-Body and it was remarkable the stylists were able to achieve noticeably different appearances despite sharing the same structural core.  Whether the 1959 Pontiac's four finlets made them a more functional Peilstege than the two on the 1959 Heckflosse seems dubious although at 213.7 inches in length (5,428 mm) compared with the W111's 192 (4,875), drivers of Pontiacs would have needed them more.  Even a 1959 Rolls-Royce Silver Cloud II was only 213 inches (5,410) long and its bustleback had no fins whatever but many were chauffeur-driven so presumably “the help” were anyway good at parking. 

The Heckflosse as rally and race car

Mercedes-Benz 220 SE, Monte Carlo Rally, 1960.

To those accustomed to how things are done in the modern WRC (World Rally Championship) or have memories of the marvellous Group B cars of the 1980s (a category which enthralled everybody except the clipboard crew at the FIA (Fédération Internationale de l'Automobile (the International Automobile Federation)) which, being international sport’s dopiest regulatory body, of course outlawed the things) it will seem improbable the Heckflosse would have been a successful rally car but the record was illustrious.  It’s best remembered for the 220 SE which won the 1960 Monte Carlo Rally but there were many other successes including the 1961 Algiers-Cape Town Central Africa Rally, an arduous event of some 13,500 kilometres (8400 miles) conducted over several weeks on a route from Cape Town to Algiers (a 190 D (a diesel-engined W121 “pontoon” rather than a Heckflosse) had won in 1959 which proved it was a rally which didn’t rely solely on speed).  First run in 1951 and based on an event staged in 1930, in 1956 a Fiat 1100 and a Ford Ranch Wagon V8 (two vehicles most unalike) had tied for first place, the latter driven by Elon Musk's (b 1971) maternal grandfather, chiropractor Joshua Norman Haldeman (1902–1974), who was an interesting character.

The most prestigious African rally was the East African Safari and a Heckflosse 220 SE won in 1961, following victories by 219s the previous two years. The 219 (W105, 1956-1959) was a curious anomaly among the post-war Mercedes-Benz saloons in terms of both nomenclature and engineering.  Using a “mix & match” approach which had been part of the transportation business even before things became motorized, the 219 used the 2.2 litre six-cylinder engine familiar in the various 220s (W128 & W180) but mounted it on the shorter “pontoon” platform used by the 4-cylinder 180 & 190 (W120 & W121) variants, the sacrificed length all accounted for by the shorter rear-doors (and thus wheelbase).  It was one of the more elaborate “de-frilling” exercises seen around the world, the variations including a lower cost version of an existing model (Citroën ID vs DS, Cadillac Calais vs De Ville or Chevrolet Biscayne vs Bel Air & Impala) or an existing body with a smaller engine substituted (Humber Hawk vs Super Snipe).  The 219’s designation was unusual in that it was the only occasion the familiar three numerals featured something other than a “0” as the last digit and it’s notable also because the factory, in a blatant attempt to evade the taxes levied on cars with 2.2 litre engines, slightly reduced the displacement.  The FRG (Bundesrepublik Deutschland (Federal Republic of Germany; the old West Germany) 1949-1990) government must have decided this was “un-German” trickery (dieselgate was decades away) because eventually they informed Daimler-Benz the 219 would be taxed as a 2.2 litre vehicle,  This brought production to an end because the effect of the tax increase would have negated the advantage the 219 had enjoyed.

The winning Mercedes-Benz 300 SE, Spa-Francorchamps 24 Hour, 1964.  Note the absence of the chrome trim which usually adorned the W112, the same weight-saving measure not always applied to the rally cars.

Although not obviously a machine built for the circuits, the Heckflosse did win enjoy success on the track, a 220 SE in 1961 winning the second Armstrong 500 in Australia, the event which became the annual Bathurst 1000.  It was even less obviously a rally car but the 220 SE enjoyed a remarkable record in the Poland Rally, winning four successive titles between 1960-1964 and the car also won the 1962 Liège-Sofia-Liège, the factory taking the title in the same event in 1963 with the new 230 SL (the W113 “Pagoda”, 1963-1971).  The Heckflosse also won the Acropolis Rally in two successive years, a 220 SE taking the chequered flag in 1962 and a 300 SE (W112) the following year.  The 300 SE was very much a luxury model which used the then still novel engineering of air suspension which provided a smooth ride but added to weight and complexity, neither quality sought by teams using cars in competition although the system did have the advantage of permitting ground clearance easily to be adjusted; to compensate for the added mass, the 300 SE used a variant of the 3.0 litre straight-6 from the 300 SL (W198; 1954-1963) Gullwing and roadster, a powerful, robust unit.  However, by 1963 it was obvious the days of the big sedans being effective rally cars was drawing to a close; the greater power of the 300 SE had permitted the Heckflosse quite an Indian summer but the immediate future clearly belonged to lighter, more nimble machines such as the Alfa Romeo Giulia, Mini Cooper, Saab 96 and Volvo 122.

Ewy Rosqvist with 220 SE Heckflosse.

However, whether on the circuits or the rally course, there was in the early 1960s nothing unusual about men winning trophies but something of note happened on November 4, 1962 when two Swedish women (driver Ewy Rosqvist (1929–2024) & co-driver Ursula Wirth (1934–2019)), in a 220 SE Fintail (Heckflosse) won the VI Gran Premio Internacional Standard Supermovil YPF (Sixth Touring Car Grand Prix of Argentina), conducted over five days and 2,874 miles (4,625 km) on some of the country’s gruelling, mountainous roads.  The women not only won but dominated the event; for the first time, a single vehicle won all six stages and they set a new race record.  To rub it in, all other competitors were men.  Ewy Rosqvist’s only complaint about the 220 SE was that when driving in the mountains, she’d have preferred one with power steering.  According to company lore, the rough road and hot weather testing of one of the competition department's Heckflosses was conducted in the Australian outback (a good place to find both qualities) and, as test drivers, the factory sent with the car the Ott brothers (dubbed by the locals “Crash Ott” and “Red Ott”); the report from the two burly Bavarians assured head office power assistance was “not needed” because the steering was  “acceptably light”.

Working as a veterinary assistant travelling between remote farms, Ewy Rosqvist was brought up on a diet of twisty, often icy roads of dubious quality and it was on those she learned the finer points of rally-style driving, travelling sometimes up to 200 km (125 miles) in a day.  With animals to care for, speed was required (in her bag was often some “time-critical” bull semen) and she took to keeping a log-book in which she recorded how long it took to go from one farm to the next; these entries she regarded as her “lap times”.  Later, she would recall the “unpaved roads, gravel paths and farm roads” with some gratitude because they honed techniques which proved good enough for her to win several European rally championships; she called her memoir Fahrt durch die Hölle (Driving through Hell (1963)).

Although Daimler-Benz was not unaware of the publicity which would be generated by having a women driving for their competition department, when in 1962 the factory offered her a seat in the Mercedes-Benz works team, genuinely the appointment was on merit and with what was achieved in South America, she justified her place.  The team had appeared in Argentina with a four-car entry (two 220 SEs (W111) and two 300 SEs (W112)), the operation run with the sort of thoroughness which had characterized their Grand Prix campaigns in the 1930s & 1950s and, given the conditions encountered, it was just as well: of the 286 vehicles which started only 43 would finish.  Immediately the women made an impression by winning the first stage and they repeated the feat on the subsequent five, eventually finishing three hours ahead of the second-placed Volvo and setting a new record average speed of 126.87 km/h (78.84 mph).  Undeniably, the women were the most glamorous and photogenic in the field and they captured the country’s imagination, German language newspaper Freie Presse (published in Buenos Aires) reporting: “It was not the Cuban missile crisis [16-28 October 1962], but rather the two blondes from Scandinavia who dominated the headlines in the country’s daily newspapers.”
