Circa
1500: A spelling variant of the Middle English draught, from Old English dræht, related to dragan (to draw, drag), from Proto-Germanic drahtuz, noun form of draganą. Root in English is draw, from the Middle
English drawen, draȝen, dragen,
from Old English dragan (to draw,
drag, pull”), from Proto-Germanic draganą,
from the primitive dreǵ (to draw, pull). It was cognate with the West Frisian drage, the Dutch dragen, the German tragen
(to carry), the Danish drage, the
Albanian dredh (to turn, spin), the Old
Armenian դառնամ (daṙnam) (to turn) and the Sanskrit ध्रजस् (dhrájas) (gliding course or motion). Draught is a variant spelling of draft and is
normally pronounced the same way (draft
or drahft or with a vowel somewhere
between “a” and “ah”). The pronunciation drawt
is sometimes heard for draught, perhaps because “aught” is frequently
pronounced awt elsewhere, as in
caught and taught.

The emergence of draft circa 1500 reflected a change in pronunciation
although both it and draught are now pronounced the same. The meanings "rough copy of a
writing" and “something drawn" is attested from the fourteenth
century; that of "preliminary sketch from which a final copy is made"
is from the 1520s; that of "flow of a current of air" was first noted
circa 1770. The descriptor of a type of beer
is from the 1830s, in reference to the method of "drawing" it from
the cask. As applied to a bank draft,
later extended to bills of exchange, meaning emerged in 1745. The meaning
"a drawing off a group for special duty" is from 1703 and applies
especially to military service; the verb in this sense first recorded 1714. Related forms are the adjectives draftable, undraftable,
undrafted & antidraft, the nouns drafter & redraft (also a verb) and
the verb redraft.
Except in the US and places which have adopted US English, draft
and draught seem now to be alternative spellings and while the old distinctions
of use remain technically correct, modern practice appears to be to use them
interchangeably. Draft almost universal
in American English and draught persists elsewhere for purposes where the historical association is most
strong (draught horse, draught beer etc). Draftee
(person conscripted for military purposes) dates from 1864 in US English, the adjectival
homophone drafty (exposed to drafts of air) is from the 1580s, draftiness a few
years later. Updraft (US) and updraught
(rising air current) is from 1909, one of a rush of words created or adapted from
others to serve the new field of aviation.
Draftsman (one who draws or prepares plans, sketches, or designs) is
from the 1660s, a variant of the earlier draughtsman. In finance, overdraft (action of overdrawing
an account) dates from 1841 and by 1891 the meaning had extended to "amount
by which a draft exceeds the sum against which it is drawn". Unrelated was the use by 1884 of overdraft to
describe “a draft of air passing over, but not through, the ignited fuel”, a
use applied to ovens & furnaces.
Draught
(act of pulling or drawing; quantity of liquid that one drinks at a time), the
source of all this dates from circa 1200, from the Old English dreaht & dræht
and related to dragan (to draw, drag). The
oldest recorded sense besides that of "pulling" is of
"drinking", one suggestion being the idea of "so much as is
drawn down the throat at once", a similar relationship drag has to the act
of inhaling from a cigarette. Draught is
attested from circa 1300 as having some connection with "that which is
drawn or written" although it seems clear the original meaning referred to
writing in general, not “first draft” as is now understood. In the UK, more than anywhere else, draught retains
the functions (horses, beer etc) that did not branch off with draft.

In motorsport, drafting (also
called slipstreaming) is a driving technique which exploits being in the
slipstream of the vehicle to reduce the drag suffered by one’s own vehicle. As a general principle, the higher the speeds
involved, the lower the average energy expenditure required to maintain a
certain speed. Because it can have the
effect also of reducing the turbulence between the vehicles, it can also offer
a slight advantage to the lead vehicle.
The advantage gained in reducing the energy expenditure manifests as
reduced fuel consumption which can be a strategic advantage but the most dramatic
effect of “catching the draft” is the so-called “slingshot effect” whereby a
vehicle coming out of the slipstream can use the conserved power to pass the
vehicle it’s been deliberately following.
Six-Pack: Three drafters and three draftees drafting, Daytona
500, Daytona Beach, Florida, 2011.The technique began to be well-understood in
the 1960s but wasn’t without risk. A
vehicle of one shape could produce a different slipstream than another and at
high-speed, slight differences can have a pronounced effect, the results for the trailing car unpredictable. Additionally, sitting in the draft, enjoying
the lower wind-resistance, although it allowed a higher speed to be attained,
also meant a reduction in down-force and consequent instability. The advantages and dangers are best
illustrated on the faster oval speedways used by NASCAR. On the straights, two or more vehicles will race
faster when aligned front-to-rear than a single car, the low-pressure wake
behind the leading car reducing the aerodynamic resistance on the front of the
trailing car allowing the second car to pull closer. As the second car nears the first it pushes
high-pressure air forward so less fast-moving air hits the lead car's spoiler. The result is less drag for both cars,
allowing faster speeds. On curves however,
the load on one side of the car is higher, this accentuated by changes caused
by the draft: the leading car has normal front downforce but less rear
downforce. The trailing car has less
front downforce but normal rear downforce. In a group of three or more, the vehicles with
drafting partners both ahead and behind will lose downforce front and rear.
Firecracker
400, Daytona Beach, Florida, 1974.In NASCAR’s 1974 Firecracker 400, the lead
changed forty-five times, a record which would stand until 2010 and it’s
remembered also for one of the sport’s most audacious uses of drafting. As he was about to start the final lap, David
Pearson (1973 Mercury #21) feigned engine troubles by slowing and dropping
low on the track, forcing the slipstreaming Richard Petty (1974 Dodge #43) to swerve into
the lead. Person then was able to sit in
Petty’s slipstream, drafting past on the final corner to win the race. Petty’s reaction, recorded in the press box
after the race, was so memorable it was transcribed and published in next
morning’s Orlando Sentinel.
