This machine breaks all the rules, it can penetrate some of the toughest terrains on earth, over land, over water, from the polar ice, to the rapids of the Amazon. This is the ultimate frictionless floating machine, the incredible hovercraft.
A hovercraft, also known as an air-cushion vehicle or ACV, is a craft capable of travelling over land, water, mud or ice and other surfaces. Hovercraft are hybrid vessels operated by a pilot as an aircraft rather than a captain as a marine vessel.
Hovercraft use blowers to produce a large volume of air below the hull that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk or oval shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. Typically this cushion is contained within a flexible "skirt", which allows the vehicle to travel over small obstructions without damage.
The first practical design for hovercraft derived from a British invention in the 1950s to 1960s. They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications as well as for sport or passenger service. Very large versions have been used to transport hundreds of people and vehicles across the English Channel whilst others have military applications used to transport tanks, soldiers and large equipment in hostile environments and terrain.
In the mid to late 1980s I was the test pilot for a large manufacturer of personal hovercraft based in Miami, Florida, I also demonstrated the craft as well as gave flight instructions to prospective dealers. I was paid to rack up 3,000 plus hours on those craft, and I had a blast doing it. Shooting through no-wake zones in Miami's Inter coastal and canal system at over 40 mph raised many eyebrows, flying up onto the beach for lunch at the Fontainebleau and flying circles around the S/S Norway as she departed the port of Miami made the local news. Good times at 8" above any surface.
Incredible machines ! Really loving the fact they are not disturbing the environment as much as other conventional transportation means .
I got to ride in a large military one over 40 years ago and it was a real thrill going from sea to land, and back to sea.
2021 and this show still feels so well-made.
My brother in law was in the US Navy and he was stationed on Camp Pendleton at HCAC Unit 5 and he worked on the cushions of these immense hovercrafts, they are quite a site and are very large!.
I worked at ACU-5 repairing LCAC''s ! Amazing machines!
During the Vietnam conflict the United States had 2 hovercraft for use in the jungle. About the only vehicles that worked well there. The limitation placed on the speed of the craft by the homogenized steel armor plates weight reduced the maximum speed to about 45 mph. This resulted in the vehicles being mothballed. The advent of Kevlar armor reducing the weight penalty with nearly the same protection factor makes the vehicles a viable asset provided the maneuverability problems can be overcome. By utilizing a vent on the opposite side of the turn actuated by the steering mechanism the directional control at higher speeds should stabilize. This means that by having 1 or 2 additional vents on each side to negate the residual inertia during a turn, the craft should respond to its controls more quickly. A redesigned variant of the thrust vectoring system used on the Harrier jump jets should stabilize the vehicles quite well. IF properly developed.

I have wondered *why* the use of hovercraft in Vietnam was abandoned....
. . . wondering why the USA lost the Vietnam war, though . . .
@@cashuma5010 They lost it at Home.
@@sandemike . . . yes - first the USA (administration) lost ist morality and then it lost the support of their own people for good reasons . . .
I was going to get stuff done but found this video. This is your only go to video on Hovercraft. The best!
Wow its the first documentary in years that does not have me fast asleep after the first 10 minutes. Really sad that they would not replace the two giants once they're gone.

This old man in used to have a small hovercraft back in the 80s. I was always fascinated.
Bravo! This was an awesome documentary and I have a whole new respect for the Hovercraft. The guy who invented it really did something great for mankind. Much respect and Salute to him. I hope to one day own a small Hovercraft to go joyride in with friends and family👍🏽💯
In the words of Dr. Emmet Brown. “Where we are going, we don’t need roads.”.
I flew from Dover to Calais in one once. It was quite an experience. It was a rough ride, but unforgettable.
Isn't the rough outside?
@Dante Williams *m
Why was it a rough ride? Because of the sea state? Or the hovercraft itself?
@ it was rough sea. I could feel vibration and it was noisy. I think it would have been worse on a ferry that day. It's over 30 years ago.
Very good history of the Hovercraft. I had build a UH16P in 1988 from plans from Universal Hovercraft and flew it for 10 years. I wish I still had it sometimes but I am getting too old to do the maintenance on the skirt which was a balloon skirt and not segmented like the new ones...............Cheers, Jim Jakosh
Hovercraft and Harrier, The Best of British Engineering!
@@saschabach3285 Yeah, agreed. But we lead and others follow. Most of the best inventions came from our shores, not bad for a litty bitty tea drinking island.

Go to, and read the list on the site he has given you, read it and weep, we've been there, seen it, done it, and worn out the tee shirt doing it, colonial prats can only buy it and try and tell the world it was there inventions, read history my friend, the U.K. has been in the for front for doing things first for many many years....Don't hate, Congratulate...
Very impressive to say the least. They should be used more for water transportation and flood rescue. Imagine if they were used on major rivers to connect travelers to other points and connections to other forms of transportation. This would help cut down on congestion. The idea of the tunnel and elevated craft are great as well. If they cut down on road congestion then trucks could move more freely and safely. Therefore less accidents and delays. That would also mean freight would get delivered a lot faster.
All of things we buy are transported by truck 🚛
If they come up with different mass transit systems for travelers that would definitely cut down on traffic congestion and wear one the highway system.
Got to drive a large LCAC in Subic Bay back in 87, was awesome! The one I drove can carry roughly 13 tanks if I recall correctly.
Bitchin! Thank you for your service Sir
@@biggin5434 Thank you! And your Welcome! My Honor! Miss it every day! Semper Fi
Not quite 13, I'd say 3 tanks plus some troops. The MBT of the USA and USMC back then was either M1 Abrahms or the older M60. The M60 was around 45 tons while the Abrahms was well in excess of 55 tons. What you got to ride was dependent on location. Abrahms was too heavy for most Philipine territory, so I doubt Abrahms was significantly deployed to that Theater.
Maybe 13 Amtracks/Amphibious Tractors would fit the bill. Amtracks of that era were inferior (still are) as fighting vehicles to the Bradley when it was introduced. 3/4 III MEF (Okinawa)
I miss shows like these, Now you can mostly find these gems on UA-cam they've given up these intelligent informative documentaries in exchange for mind-numbing nonsensical so-called reality crap shows.
And that is why I do not watch TV, I do not care what color a transvestite is going to dye its hair today .
i agree there they need to take shit like only way is essex, rich kids go skint ect ect off tv and put programs like these on instead at least with documentary's you learn something only thing you might learn ( if your a girl that is ) from only way is essex is how to get the melted in a oven barby doll look as thats how all the well wont say girls look on there
What do you have against Essex? Get away from the slummy, drug gang controlled parts, and Essex was quite nice when I was last there.@@shaunparkinson7121
50:24 And that, my son, is how baby hovercrafts are born.
A real hovercraft
+karbengo Why is it when people post the dumbest fucking comments a million people respond.
Then when pure comedic genius comes around as such it goes largely ignored.
Kudos....it made me laugh pretty good.
+Christy Hovercraft Can anyone who has the cash buy a hovercraft?
Or do I have to wait until one is born in the wild and capture it like in this video?

ITS AN AMAZING CRAFT THE WORLD HAS EVER KNOWN. ITS A DUAL PURPOSE STRIKE ANYWHERE BOTH LAND AND WATER OPERATION.
The Hovercraft story was interesting informative and educational.
George Marsh ok up
George? Hi! What a refreshingly sensible Comment! No politics, no bitterness, no spite... Are you sure you're feeling OK? ;-)
yes but the inventor should of took the interview after crossing the english channel instead of going for breakfast?
Look how light pull it is when out of gas!
@@rudy103069 maybe true but he was English not American so didn’t need to tell the world how good he was.
Are you really quite sure the us military took hovercraft to the next level? The SR.N4 mk3 weighed 320 tons cruised at 60 knots with a maximum of 83 knots and these were initially constructed in 1966. I think most would agree the uk already achieved the next level.
what he means is the military version is more than just a ferry boat
The SR He's are beasts. I could not believe the size of it when I first went for a crossing of the English Channel. I think we crossed it in around 16 minutes. The things where huge with the four giant turbo fans and a a giant Union Flag on the side. As a kid I was in awe!
THE LAND OF US !!!, haha check out the Russian military hovercrafts makes the american ones look like toys !lol
sweet jesus that some rapids! tbh ive only ever thought of the hovercraft as a fair weather transporter till now. impressive.
Thanks for finding such a cool old school video
The old days...... Not much left of this today.
A small tri hull carbon fiber ridged boat married to a hover craft is just what the doctor ordered, for insertion & coastal inspections & ferrying between ships & shore.
20:28 wow I never knew just how tough those things are! I would never have imagined they could get over those kind of sharp ice ridges
they are just AMAZING their only drawback i can think are high running n maintenance cost, with new technologies making engines cheaper to run i believe they have a Great future just hope they will never die
polygamous1 Sozou they also cost slot of fuel..
Thank God for the British and the Americans who Gave them Support, where would we be without each other...?
I remember crossing the channel to France more than a few times in the SRN4. I thunk the best trip was when I was allowed to ride almost the entire trip from launch to landing in the cockpit area. What a great experience that was for a kid my age at the time. I got the full run down of exactly what they were doing the entire trip. The pilots LOVED that I was hanging on every word. When they let me grab one of the control sticks, I was in absolute heaven, lol. We actually did a few trips in an executive hovercraft that was extremely posh and I have to say, it was like riding in a very high end executive jet with 3 attendants serving food and drinks. It was an awesome thing!! 👍🏻😎👍🏻
46:07 That scream reaches beyond time and space
Are these beautiful pieces of ingenuity ever deployed in dangerously snowy regions, say, Alaska, in human rescue operations, since they are at home on all types of terrain?
Jay Young Yes. Google.
David G Thank you.
Jay Young I love that you ask that, although in the video, there is footage of a hovercraft in snowy and dangerous regions... Did you watch the first three minutes then get bored and move on?
Jono Pedersen Touche. My bad!
;D Hehe, no problem, just saying ;)
Documentaries , are for me, a cheap cure for insomnia. I would go right to sleep after 20 min.
Your ignorance is noted.
Travelled on one across the English Channel, like a bumpy bus ride and only 35 minutes, the good old days are long gone sadly!
I remember being at the commission ceremony for the first LCACs. I was in awe of them. They are monsters.
better than a LARK too!
Back when documentary's were actually good
Make the hovercraft great again!!
FUCK YEAH!!!!😎🤘🤜🤛
that's an ultimate drifting vehicle !!
El hoovercraft es el mejor medio de transporte anfibio que se inventó y como ferry también,el hoovercraft nomaaaa y pa los contras también
I had the opportunity to buy one of those racing hovercrafts last summer. Needed a full restoration but it was only $100. Didnt get it. My dad thought it was garbage not worth taking home. The guy sold it a few days later for 500 after i had given him some more info on it. Was a rather rare model to be in the US. built in england
Russian navy has some awesome Hover crafts in Kaliningrad. I saw them when I worked on a gas pipeline outside the shore of Kaliningrad a few years ago
I've seen those, they are cool and surprisingly affordable on the used market
Its a shame that Kaliningrad doesn't belong to Poland.
The zubr?
Hovercrafts are absolutely amazing machines! I loved them since I learned they exist at all playing Diddy Kong Racing 😀
Ah yes, the good old days when The Discovery Channel and TLC still has descent documentary. I remember seeing this episode on TLC as one of the "Extreme Machines" episode. These channels have nothing but garbage shows now.
Bo Han
Reality TV ruined it all
true that man... those fucking scripted (un)reality shows make me sick. Having DC and TLC broadcasting them feels like betrayal to me. Such a waste
k
dont be to sure
True that, now they only have crap.
As a child I crossed the English Channel four times this way. That was over 45 years ago..I remember it being very noisy.. But it had a very good ride, even in choppy weather.
Me too, but it vibrated a lot. I spent the whole journey trying the read the safety notice on the back of the seat in front but could never quite focus on it.
Very nice documentary about an amazing machine, the hovercraft! I wish they did not discontinue the hovercraft ferry service, infact we should have more hovercraft being used as ferries in coastal areas/rivers/canals and we could even have hovercraft playing the role of a bus on land with no/poor roads, how about 'HoverBus'? :)
This is a situation that played out many times,there were two or more teams working at the same thing.
Back in 2007 when catalina was on fire the LCAC's brought fire trucks and firefighters to help save the town. They are and very loud and huge. I've seen them many times out between camp Pendleton and San Clemente while out fishing.
So sad the grief that they put this brilliant man through. It's been that way all through history though. Remember Fulton's folly when he designed a ship to be powered by steam? The great lesson to be learned here is each one never gave up and neither should you. Stick to it or fail your dream.
No out come is Guaranteed, You gotta get out there and hustle and have a good idea to start with. Even then you might not be successful
It seems the technology still has a long way to develop further. I hope to see more development along these lines.
other then it being LOAD!! and it needs to stay on to flout unlike a bout you can turn off and fish .
@@daymenleo6895 it can float like a boat no problem with engines off. This documentary is nearly 30 years old now, hovercraft tech has come a long way since then.
The police in Oshkosh Wisconsin had two HC's. They had to rescue some guys fishing on Lake Winnebago. The first one got stuck on the broken ice so they called for the other HC. It too got stuck. So they knew of a guy that had an air boat. They had him go out and rescue all involved. That spring the police had their own air boat and sold the HC's.
Ric Trexell: . . . nice fairy tail . . .
Ric. How many miles can an airboat travel over sand and gravel 200 300?
ทำแบบนี้แลืวก็ดีจ้า
The one question they didn't address is--What happens if the engines fail while on the water? Does it float or sink?
blueknight: They’re constructed with watertight bulkheads so can float when not on its cushion of air
@@UKWMO YEAH but if it loses power in the rapids, ITS GOODBYE TIME
@There's No God fukkk your own arse, a boat with engines cannot even go through rapids idiot..
@@OzzieWozzieOriginal Ummm, yes they can and do. ua-cam.com/video/_e4MWI2EYFA/v-deo.html
Christopher Cockerell. a very humble gentleman.
BBC. "Can we interview you"?
Christopher "I will have my breakfast first"
A brilliant mind that just kept going until he conquered the task
they need to make some kind of small high intensity blowers to mount on the front and rear corners,and that would give small hovercraft more stability in turns and keep it from yawing. you definitely couldn't replace all the cars with them, because it would look like bumper cars at the fair. at least as unstable as they are now.
The instability of many small hovercraft comes from the segmented skirt design. The 1980s SCAT is notorious for this. Newer hovercraft like the Coastal-Pro are more stable.
golden age of hovercraft on earth is yet to come
yeah🌏🌎🌍
One of British greatest inventions
We wold like to see this back on the channel route with more economical engines and product development.
i always thought hovercrafts were inflatable like rafts, and i always wondered how they didnt bust or get punctured. now i know
1:07 Wow, I never knew hovercrafts sound exactly like an electric guitar! How do they do that?!
I have always wanted to own a hovercraft.
YOU CAN PICK THEM UP DIRT CHEAP
I remember the Dover To Calais Hovercraft service well. 1981 to 2000
Wow 70mph with 50 cars and 400 people. Thats a nice ferry ha. And crazy when you think of where it can go.
now thats what I call a superb video, educational and very entertaining in its content, great narration too, MINT" CHEERS.
Saw these bad boys training in Devon. Brilliant
Good machine
I always wondered if 'spring loaded' drop down rudders couldn't be deployed whenever sharp turns were needed and retracted for normal forward movement, increasing the maneuverability of these vehicles on water without the complicated and expensive 'rotating power pylons' used by the bigger versions...
Man, iv often thought all vehicles should have some kind of alternate movement system. Pillars on the corners for faster turning. Some kind of arms or legs thatll let a vehicle climb out of stuck situations. A winch harpoon to shoot into large trees to pull u forward 😄.
I've got to have one of these babies. To be able to traverse just about any surface in any weather would be wild. I wonder if I can get one with a wheelchair lift and hand controls. Alas, 'tis but a dream, but what an exciting dream.
Why don't we see more of these in operation? Why are they not commercialized as recreational or even every day vehicles?
Awesome and interesting video, I see two problems/hurdles/hindrances with the hover craft, bearings for the fans and the rubber skirts wearing out like tires on a car depending on terrain, but I would imagine the experts would have thought of these things.
THANKS FOR VIDEO AS GREAT MACHINES IN WORLD TODAY
Vert cool, Slainte ❤
Hovercraft - Ultimate Amphibious Machine?
No. THAT'S the Toybota!!!!!
Why do i keep thinking about the Top Gear hover van all the way through this video.Lol
I LOVE hovercraft!
मुझे यह वीडियो अच्छा लगा धन्यवाद।
to the makers of the hovercraft there is no need to release that much are under it if you have holes built on the sides you can control which way to go and still be able to hold the air inside of it just like a balloon but by controlling which ports which holds the air goes out of it it would save in fuel
Ohhh how I want an LCAC!! I could just float over the traffic on my way to work!
i dont think you realise how big the lcac is lol
Awesome video
Imagine being the teat driver. I am a little jealous.
Still can be improved! By making the bubble bigger, and more lift. But still the rite ideal
Nice transport I would love to own one
So this machine could be put out of operation, 6 ft T post halfway into ground sticking up, would stop this million dollar machine, puncture the skirt or get it stuck on top of a fence post!
your probably right, after all the billions in development they don't add into the cost of each unit. the US government had to make something of it, this was actually the most costly fail of its time, they kept getting promises and kept throwing money at it to the point if they didn't make something of it, it was probably going to be some ones ass. beautiful display of government spending
Wouldn't they just go around a single post? And if it's a fence sturdy enough that a hovercraft as heavy as that couldn't push it over with the weight of the hardware above the skirt, a lot of other military vehicles would be in trouble too (you can't really risk ramming an obstacle with an expensive military ship either).
The hovercraft has specific jobs that it's very good at (particularly amphibious operations and on snow and ice), but if its sheer weight and thrust of its engines won't sail over or push over an obstacle, you need a tank, probably.
Probably a very good thing this was not in National Geo back in the day. Pretty sure I would have redone a lawn mower n a raft or two. Yeah , My folks loved me enough as it went ...
ฉันใช้แต่ตอนนี้ไม่มีในหัวของฉันแล้วเพราะรู้ว่าเขาโกหกฉัน
Grower not show(er) baby
I'd love to have one for when I'm down the beach it's a pity that there's not many in service now
lovely work fd
My 4 yr old just informed me that he wants to fly one of these in the US Navy. I said good choice!
smart kid
A hovercraft was invented by the UK.
British government strongly supported and put into practical use.
It is great.
Till about 50 years ago, hovercraft was a type of aircraft.
5 centimeters altitude, let's laugh (^ ^).
Actually the US invented one called the glidemobile during WWII, however, they could not file a patent
One of the coolest means of transportation ever invented. Those little single seaters at the first would be a blast.
I have One question?
Can be possible to make frictionless surface and make a big transportation use of inertia.......
???????
Please suggest answer.
Yes
they are used for heavy lift in places like Alaska and Northern Canada mostly in the oil mining industry
these machines are very utility in structure
" my hovercraft is full of eels !"
I do believe it was Sir Christopher Cockerell who was responsible for Designing & Building the SRN 1 hovercraft !
It is not exactly all terrain, but everywhere that is along seashore and flatter lands. Rocks will damages it.
Do we see this same technology being applied to high speed railroad transport?
Jay Young The Japanese use a magnet rail that keeps the train inches above the steel rail. It essentislly rides on air.
David G magnetic lavitation trains or maglevs actually were a german invention, later sold to china.
Quarkhammer Thanks.
David G Maglev trains do not use air at all for levitation, it uses magnetic fields. The hovercraft technology uses way too much energy to be useful for public mass transportation.
David G No it does not ride on air. it rides on magnetic forces which would work even if you operate in a vacuum with no air. Perhaps at very high speed there could be a contribution from the air being rammed under the vehicle but that is only a by product of motion not the main principle of operation, Professor Eric Laithwaite of Britain was interested in this technique,
They build one of the most technically advanced vehicles around, but the windscreen wipers look like they're off a 1962 prefect.
I am sure that these hovercraft have a lot od maintenance on the skirt.
this video is a good one!!!!!
These are awesome, but what happens if one of the lift engines break down out over the water?
Hovercraft will float on water without the air cushion. The air cushion does not provide buoyancy, it provides lift above the surface, whatever the surface happens to be.
Looks Fun
Lot of nice footage on hovercraft.
hey, i grew up watching this series in the Discovery channel...
