Much mystery, myth and
legend concerns Oulton Broads place in the history of the
Hovercraft.
Christopher Cockerell set up his first boat building
company in Oulton Broad and had his workshop on Saltside Mutford
bridge opposite the small roundabout.
Whilst Cockerell and his wife worked here he worked out the
mathematical formula for lift and thrust which where to become
theory for the hovercraft.
During this time he rented day boats to tourists from the free
quay on the freshwater side. This was very unpractical, as he had
to often walk across the bridge with fuel to refill his crafts.
However whilst in Oulton Broad he met A.D Truman who owned a
boatyard near the Maltings on Oulton Broad. Truman specialised in
lightweight racing craft, and could produce very thin, strong and
lightweight material. It is a measure of Cockerell’s trust and
friendship with Truman, that he gave him the plans to the prototype
of the hovercraft before patenting them. Truman took these plans
and built the prototype for Cockerell. Much of the historic detail
was shrouded in mystery for 50 years as the successful test flight
led to the project being snapped up by the government as top
secret.
The first test flight took place at Somerleyton Hall where today
a plaque commemorates the achievement.
The Background to the History of the hovercraft
It goes back farther than you might think. . .
1716 - EMMANUEL SWEDENBORG, philosopher and
lateral thinker dreamed up the idea of an air cushion
vehicle, which would be powered by very enthusiastic oarsmen.
Good idea, but the power sources were unavailable for comment.
1870 - JOHN THORNYCROFT experimented with a boat,
which was designed to move along on an air film trapped
under its hull. Great idea, but the steam engine power source was
not up to the task.
1916 - DAGOBERT MULLER, from Austria, built an
air film torpedo boat. Great invention, great name, but
unfortunately 1916 was not a great year for Austria and with the
First World War in full swing it was dropped.
1950s - Dr WILLIAM BARTELSON, a country doctor in
America devised and built a series of 'air cars', which he called
'Ground Effect Machines', in order to get around the problem
of visiting patients in the more waterlogged parts of his practice.
He, and other enthusiasts, were beaten to the patent punch in
England by CHRISTOPHER COCKERELL, who was, after years of
intense British indifference, credited as the inventor of the
hovercraft. Cockerell approached various
aircraft
and ship building firms
with his idea, but no one wanted to know, because no one could
decide what his invention actually WAS. When it was built his
first model and took it to the corridors of power and the Men
at the Ministry immediately slapped a 'Top Secret'
label on it.
It was only after they heard that OTHER countries were
developing similar vehicles that the invention was FINALLY
allocated to Saunders Roe, (flying boat manufacturers) to
develop in conjunction with the National Research Development
Corporation. Finally, in May 1959 the SRN1 flew for the
first time.
1960s - DECADE OF THE HOVERCRAFT - America gave us
the moon landings and the Monkees. We gave the world the Beatles,
Carnaby Street, the World Cup Winners in 1966, 'Wonderloaf', Alf
Garnett, and Hovercraft.
In the '60s the hovercraft went from being a garden sized flying
cup and saucer (the SRN1 was also known as 'the Flying
Saucer') to a cross-channel passenger and car ferry giant.
These were the years when
hovercraft were 'cool', and often reported as 'an exciting new
form of transport that will revolutionise the way we travel'.
This was when the classic designs came forth. They were
aircraft technology vehicles. They smelt and sounded
like aircraft, could go as fast as speedboats and could go
where no ship, car, tractor, tank, ambulance or bus had ever
gone before - and all without being called 'Enterprise'
.
All the enduring designs of hovercraft happened in these ten years.
Apart from tweaks in the technology, little has changed
since.
Saunders Roe and Westland gave us the beautiful
SRN2, the Bulldog Drummond style military
SRN3, the
'workhorse' SRN5 and the 'stretched' workhorse number
two, the multi-purpose SRN6. Finally the two companies
merged to become The British Hovercraft Corporation and
went on to build the mighty SRN4 and eventually develop
the military BH7.
Vickers Armstrong had also been working on hovercraft design
throughout the late 1950s and had come up with the experimental
VA1, the Jeep-ishly functional VA2 and the first
passenger ferry, the VA3.
While Hovercraft Development Ltd kept on developing the
air cushion vehicle, other companies such as Denny
and Hovermarine devised water-borne 'sidewall' craft.
Tracked hovercraft (which have YET to get off the ground, so
to speak) were designed and tested, and hovercraft built from
plywood and plastic with inflatable hulls started to appear.
Vosper Thornycroft (boat builders famous for their WW2
torpedo boats and coastal craft) carried out pioneering work on
semi amphibious craft. Meanwhile smaller companies like
Pindair and Britten Norman contributed more than most
people realize towards the modern boat styled air
skimmers (just off the ground enough so that it matters)
which proliferate to-day.
Proliferate? Where do
they proliferate? you might ask. Well, apart from one or two
famous exceptions, certainly not in the public passenger
market! Which is sad because, statistically and historically,
the hovercraft IS the safest form of transport in the
world - EVER!
No, they play hidden roles in parts of the world that you and I
have never heard of, exploring places with names I can't pronounce,
and carrying out such work as geological or geographical
studies. They are also used in offshore roles such as fast
attack/patrol/landing craft. Now and then someone uses them for
things like rescue vehicles and for humanitarian support
missions. More often than not they are used for military
purposes, and even now there are some very unusual hovering
machines being developed 'behind closed doors' - and we are back to
flying saucers again...
So now the best 'classic' hovercraft of the 1960s are
consigned to the history books Most of these vehicles were
made in relatively small numbers and do not exist anymore. The few
originals are either rotting away fast, or are at the
Hovercraft
Museum in Lee on the Solent on the South Coast of
England, where selfless volunteers do their best to preserve
them.
Oh and by the way, if you are wondering if there is a hovercraft
museum closer to you, then wonder no more; the museum at Lee on the
Solent is the ONLY hovercraft museum in
existence....anywhere...
In the meantime, racing hovercraft as a sport has been
around for decades and is still flying strong to-day. There is also
a growing world-wide interest in model hovercraft building
and a model hovercraft racing fraternity is forming in
various embryonic ways in various countries.
Still used today..
The SH2 (see right) is road transportable and available for
Environmental surveys, sampling, coastal monitoring, dredging and
civil engineering support, safety boat, film/TV camera platform.
Hovercraft operate effectively over land, mud, water, sand, snow
and ice.
