Another advantage is that they're pretty good at not triggering mines. Lower magnetic signature for naval mines, and very little surface pressure for land mines.

Except the kind of mines with prong triggers...

[@GYI5U]

Ah yes I saw this explained in the documentary "James bond 007 die another day"

[@stefflus08]

It does nothing to lower magnetic signature other than moving the hull a few meters away. Material choice is much more important, because magnetic triggering is much more advanced than it used to be. Hovering can reduce or eliminate shockwave coupling between water and hull, which is a bigger deal than the more visually spectacular side of a naval mine explosion. And it can be done so it makes very little acoustic signature for mines that trigger by sound. But the propeller driven models fail in that regard.

[@skyden24195]

For Christmas of 1989 I received a one and a half foot-long, remote controlled hovercraft. It was a challenge to control but a lot of fun. However, given that industrial/commercial/military strength hovercraft skirts are relatively easy to damage, I'm sure you can imagine how much easier the skirt on a much smaller, toy hovercraft would be. I managed to keep my hovercraft up and running for about a year, but in addition to the eventual skirt damage, like so many remote-controlled vehicles of the time, the rechargeable battery-pack steadily lost its rechargeability, so the hovercraft would start dying out in less and less time. This aspect almost saw my hovercraft sink into a small creek near where I lived at the time, (Illinois, USA).

[@nos9784]

No emergency flotation construction by using styrofoam or something? Huh. Well, mine didn't either, but we made that for classroom experiments. Circular, ~3'3", with a car battery, two camping mattress blowers, and room for one person. That was fun!

[@reinhard8053]

I also have such a toy. It is really fun to go on different surfaces. And it has a styrofoam body which floats. You can observe every slightly uneven road as the hovercraft goes to the side of the slope if you slow down.

[@skyden24195]

@@nos9784 nope, no back-up floatation implements. I remember that when my craft started to lose power in the creek, I yelled for my younger brother, who was standing closer to the creek, to jump in and save it. Of course, he just looked at me like I was crazy. Fortunately, there was enough power to get the craft closer to the edge where I could reach it without having to put more than one foot into the water. (This happened in late fall/early winter, so the water was very cold.)

[@skyden24195]

@@reinhard8053 those little things where part of the challenge.

One of my most treasured memories is my grandad taking me to the seaside to see the hovercraft. The volume and scale of it was mind-blowing. When we got back he challenged me to a drawing contest, which he obviously dominated. Problem was that I was like a 7 year old, and he was one of the top electrical engineers in the country that CERN kept on trying to scout to follow-up on some 10kA switches he designed for them but he wasn't interested in leaving his village. He had a minor leg-up in technical drawing skills

[@S.E.C-R]

I’ve always been fascinated by these things… in 2019 we had a massive Navy hovercraft “storm” our beaches here in Warrenton Oregon twice, once to bring supplies from a ship sitting out in the ocean and a second time to bring troops, all as a training exercise. It was the coolest thing I’ve ever seen!!

[@hippiesaboteur2556]

Yeah I grew up here in eastern north Carolina, where our coastline is nearly almost entirely flat, low-lying expanses between the ocean/intracoastal waterway, estuaries & salt marshes, or swamp. The majority of the terrain almost anywhere throughout the outer banks (which for the most part are very low, narrow & skinny chain of coastal islands, and form a protective natural barrier that runs the entire length of NC's coast. between neighboring barrier islands, typically one island's northern-most tip & the southern-most tip of the other, are the waterways connecting fresh inland waters to the ocean, and also contain channels for maritime traffic, allowing for passage between intracoastal or inland waterways, local or private harbors/docks/slips, & the 3 state ports to & from the open ocean and much larger, deeper main sea lanes) is by and large mostly long, wide, flat, open sandy beaches. This exact kind of geography was particularly chosen right before the second world war by the War Department (now the Department of Defense) as the best location to build & utilize as Marine Corps Base Camp Lejeune, the perfect place on all the east coast of the US, and most ideal type for amphibious operations, especially with regards to LCACs. From my childhood to this day, I've lost count of how many times I was spending a day at the beach with family or friends, there would be US Navy ships anchored a few miles off-shore, and all of a sudden multiple LCACs and AAVs (amphibious assault vehicles aka Amtraks) would come into view on the horizon, and within a few minutes would pull up onto the beach, sometimes just a few hundred yards down the beach from the rest of us where Navy Seabees would be waiting for their arrival. they'd drop ramp and Marines, their gear & vehicles would disembark and proceed further inland, and then those LCACs would fire their engines back up again and return back to ship... All of this in a matter of a couple minutes. Truly an impressive sight, that is, when you weren't at times having to cover your face & eyes to keep from being sand-blasted by the excessive amounts of beach sand kicked up whenever their engines were still running wide-open. Totally worth it though to be able to watch all that kind of stuff, especially from that far away

Some places still use hovercraft as both cargo and passenger ferries. There are communities located in remote area's where the only access often is ice road in winter, and hovercraft in summer. marsh/bog/permafrost tundra can be very inaccessable during the summer and many of the rivers are unusuable because of shallows. So in cases like this hovercraft transports come in very very useful.

Agreed, though there is also 1 other aspect that made an and to the SR N4 hovercrafts. They contained 4 Rolls Royce 3800 shp gas turbo engines (the Mk. III anyway) which burned 1000 gallons an hour at a cruise speed of 50 knots. Max. capacity was 8068 gallons.

I'm a geologist who does a lot of work on large, salt lakes in Australia. A number of efforts have been made to use hovercraft for transport across these salt lakes....even to the point of making hovercraft mounted drill rigs. These efforts all failed, unfortunately. The salt crust on most of these salt lakes is so rough and jagged that the hovercraft "air skirts" tended to shred quickly, thereby requiring frequent replacement. This became prohibitively expensive and eventually killed the project. We're currently looking to revive the concept with a very specialised hover drill rig. We're looking to fit an aluminium rim around the base of the air skirt to resist abrasion from the rough lake surfaces. There will be no forward propulsion for this rig. It is simply a skirt and fan designed to make the rig hover. The rig (weighing approximately 20 tonnes) can then be pulled along slowly by a light ATV type tracked vehicle. The aluminium rim scratches along on the top of the jagged salt, protecting the skirt. If we can make it work, our life will get a whole lot easier.

[@creatorchris712]

Why cant the new skirt with the aluminum be used while the rig has forward propulsion ?

[@ohlordy2042]

@@creatorchris712 It probably could....anything is possible with enough money and effort. However, in the interests of making it as cheap, simple and low maintenance as possible, there will be no forward propulsion. A lack of propulsion is no real loss to the versatility or usability of the rig, anyway. It typically spends months on individual projects drilling fairly closely spaced holes, so only needs to be moved long distances on a handful of occasions in a year. And, by making it "weightless" with an air skirt, towing it long distances over the lake is no major logistical challenge.

[@sylviaelse5086]

I crossed the English channel eight times or so on the hovercraft. It definitely wasn't smooth, and it equally wasn't quiet. But I found the trip time short enough for sea-sickness not to be a problem. But if the train had been an option at the time, I'd have used that instead, once the hovercraft's novelty wore off.

I live in Portsmouth on the south coast of the UK and nearby in Lee on Solent back in the early 70s was a unit set up called the interservice hovercraft trials unit. It was created to test and evaluate the potential use of hovercraft for use in the military. Ie navy and army. One of the tests they did was using the BH7 for testing the effects of mines on hovercraft. I have video of some of this stuff. Not sure if any of it's on KZbin. Coincidentally, there's been a hovercraft museum for quite a while now and it's in the very same location and that BH7 is there together with a number of other craft including 2 of the SRN4 cross channel hovercraft. I actually watched one of them come in which had to use mobile blowers as it was unserviceable. The hovercraft had to cross a road to get from the sea to the base so traffic had to be stopped. I believe you can see the BH7 on street view.

You didn't mention but there are two combat hovercrafts in Russian Navy at the Black sea. They are called Bora and Samum and belong to completely different kind of hovercrafts.

Samum is a different type of hovercraft, called Surface Effect Ship or sidewall hovercraft. This video is basically about Cockerell's design and its derivatives and mostly ignores other types of hovercrafts, that were created since circa 1910-s.

[@coned07]

small mistake: hovercrafts don't hover with newtons 3rd law, they hover by creating a high pressure zone of air between them and the ground. The craft can't touch the ground (or water) because the high pressure air is stuck between the ground and the hovercraft. They don't fly because if you remove the ground, the air can move freely out from under the craft. hope this makes sense

Payload was 1,000 lb, hovercraft weighed about 900 lb as I recall.

[@beef1541]

Bering Marine Corp runs one/some in AK. Dad built a 16' one, small ones are super simple, low hp, fuel efficient as far as watercraft go and pretty capable, but wind drift is a nuisance in a breeze and can get dangerous with strong gusts.

I think the Ekranoplan also deserves a mention in the video. Although not a hovercraft per se, it still uses the ground effect to move. Yes, I know it's Russian but I can't deny they look extremely cool.

[@richmcgee434]

There are actually a couple of old 1980s tabletop wargames (Helltank and Helltank Destroyer) that postulated a near-future where warfare included surface effect ships as tank and infantry transports. Bit optimistic about that technology, but they also had armed ground effect vehicles acting as mechanized scouts, which also hasn't come to pass. There's also the somewhat earlier and much better known Ogre and GEV games, which again included both armed and infantry transport hovercraft - in their case, justified by tech breakthroughs in power systems, ultralight "bi-phase carbide" armor, and widespread use of railguns that made the GEVs the best option for long range scouting since helicopters and aircraft die the moment they clear the horizon. The Hammer's Slammers novels (and the games spun off from them) are probably the best known "hovertank" franchise, with 170+ ton armored juggernauts plated with irridium armor and using fusion engines to support their mass and give them good mobility. That one's set far in the future though, with interstellar colonies and loads of brushfire wars involving hired mercenaries from high tech planets. Fighting against them with the kind of primitive local gear your average colony can build locally is sure death so whichever side in a conflict can afford the better mercs tends to win. It's pretty grim as settings go.

[@shadowslayer205]

There's also Battletech, in which realism-inspired hovercraft are a staple of the light armored/utility vehicle class.

In the 60's my father was a fleet airarm pilot based at HMS Daedalus. I can remember he was invoved with the Royal Navy's assessment of hovercraft. I believe they built a slipway and a set of traffic lights to allow access to the Solent from the airfield. Since the UK lacks large wetlands, tundra or ice fields they were a bit of an expensive way of doing things.

My grand mother had a hovercraft in her house in the mid 1950's made by Hoover as a three year old I could ride on it despite it not being made for that purpose, later on in life I crossed the channel in a hovercraft.

[@Axeiaa]

Interesting that the speed limiter is the air cushion not collapsing. With the advances in material science and nano structures I imagine at some point they'll make a skirt that unfolds really easy from the inside but nearly impossible to fold in from the outside which would enable silly fast hovercrafts.

[@ckm-mkc]

I've taken a hovercraft across the channel, it was incredibly uncomfortable, like being in a paint shaker. The chunnel is much, much more comfortable and more convenient.

[@europhile2658]

I did one ride on a cross-channel hovercraft. I agree with all your comments and would like to add one - the sea spray prevented you from looking out. At that time Hydrofoils started and they were much better. Probably they failed as well - an idea for a future video? Also Ferries are much better than people think. For truck drivers that multi hour break is a valued rest stop

[@robertmorey4104]

[@quint3ssent1a]

Mekong Delta was probably the place where hovercraft use made the most sense. Huge swampy area where overgrown swamp and river channels come hand by hand and where no constant roads were ever built - basically this was the golden land for hovercrafts.

[@ATASD]

Why it was? It doesn't exist anymore?

[@hackman88]

2:01 Hovercraft do not hover based on Newton's Third Law: Action & Reaction. They hover because the air pressure below them is greater than air pressure above them.

[@Alex-og3ev]

There are several more regular passenger hovercraft services in Russia at least. They operate as river ferries and their main advantage is that service does not stop in spring and autumn when ice sets/melts. Where usually there is a long gap between traditional ferry and ice road services. Those are quite small vehicles though, 9 to 20 passengers iirc.

[@andrewthomson]

You're in Canada!? Awesome to see us so well represented on KZbin! Greetings from Ottawa!

I served on hovercraft in the US Army. During the 80's and early 90's the Army operated the LACV-30 which stood for "Lighter, Air Cushion Vehicle, 30-Ton. (Lighter refers to a vessel that is used for transferring cargo from ship to shore, not it's weight or size.) The LACV-30 didn't really live up to its 30 ton name, because you had to count the fuel as part of the weight, and as I remember, we could carry 3000 gallons of fuel, which ate up a big chunk of the cargo capacity. It burned about 250 gallons per hour. We used to joke that it's primary mission was to convert JP-5 (aviation fuel) into noise. We were very good at that. Sometime in the mid 90's the Army got out of the hovercraft business and sold them off. I do get to tell people that I was an Army naval aviator though. Definitely one of the stranger jobs in the Army.

[@KevinSmith-ys3mh]

Operating from Army LST`s? Another oddity the US Army is trying to offload, along with air cargo transport as so I have read!

[@NWChickenDad]

@@KevinSmith-ys3mh The Army didn't have any LST's. We would cooperate with the Navy if we needed to be hauled somewhere. The Army did have 5 LSV's (Logistical Support Vessel) which were 275' landing craft, as well as a 375' landing ship called the "McHenry". We also had 1600 and 2000 class LCU's, as well as LCM 8's (Mike boats) and various tug boats and barges. Quite the little navy. Most of it operated out of Ft. Eustis, VA. I was stationed down the road at Ft. Story, VA, where we had two hovercraft companies, as well as a unit operating the LARC-LX, a giant boat/truck with wheels.

I took the hovercraft from the UK to Calais back in 1984. It was like sitting in between two jet engines, although not everyone will agree. Also, the windows weren’t too much use as the downward fans blew spray up to obscure any view. Very comfortable ride though.

This brings back memories, as my dad worked for Hoverloyd in the 70s and 80s. Did a couple of trips across the channel, and it was loud, but I never had an issues with feeling sick as a youngster. I also had the chance to help direct a hovercraft into the departure/arrival area at Hoverloyd’s terminal. Unfortunately, these amazing machines were always very expensive to run, and the Channel Tunnel took away their speed advantage.

Sailing up the Saint Laurent on a container ship (same week as the ocean ranger) our boat was ice strengthend and at Québec there was a wee ice breaker stuck solid. Being nice guys we took the time to break it out. Hovercrafts couldn't do that.

[@frankteunissen6118]

I’ve traveled Calais - Dover v.v. by Hovercraft many times way back when they operated. The gain relative to the ferry was not just the speed of the craft itself, but: - no mooring and hat our maneuvering; in fact they hardly reduced speed upon arrival and just parked the craft down, turned the engines off and opened the ramp. - and the limited nr of car’s & passengers it carried. Boarding was done in minutes. Disembarkation was even quicker. From my point of view it was ideal. Even the Tunnel isn’t as quick.

If the Hovercraft's downsides can be mitigated it'll be a hell of a tool for whoever pulls it off.

I still think a SRN4 sized hovercraft could be viable, if it was SES. That is a hybrid hovercraft, with the solid sides going into the water. Only the front & back have flexible skirts. This is much better in choppy seas. It also lets you have propellers going into the sea like a ship. This is no longer amphibious, but it lets you run on cheap diesel engines rather than expensive gas turbines.

[@wackowacko8931]

Another use for hovercraft in Canada and Alaska is to resupply mail, fuel and groceries to small towns in winter that don't have access to a runway and are right next to a river. Rivers are like naturally occurring roads when they are iced over. When the ice is thin on the river, it is about the only way to resupply these towns. Once the ice is thicker, trucks and snow machines can drive on the ice to supply these towns.

[@NoahSpurrier]

I wonder what happens when a hovercraft runs over a person sleeping on a beach or swimming in the water. Deaf people go to the beach, too, you know.

[@hoverbovver]

There was an incident when a SRN4 ran over someone collecting fishing bait far off shore. He would hardly have felt anything. But the skirt would have knocked him flat. I have deliberately been under a hovercraft for research purposes and the air pressure and speed is so low you barely notice it.

[@NoahSpurrier]

@@hoverbovver that’s pretty cool. So you could, in theory, lie down flat on a beach and have one of these things run over you without harm.

our military (Finland) had only one hovercraft ever. they started it only ONCE, and then decided to get rid of it. it was meant to be somekind of quick response commando or whatever unit's vehicle, but having a machine that can be heard about 100 km away kinda dampens the idea of sneaky soldiers....

The big ones did not go out of service due to multiple hiccups - the SR.N4 was in service for 32 years on cross-channel routes and was becoming time-expired. When they retired in 2000, the channel tunnel had already been running the same basic route (Folkestone/Dover - Calais) for six years providing similar crossing times.

Excellent video! Hovercraft are very cool, but they are inefficient fuel guzzlers, as you pointed out... rather like the Boeing 747 and Airbus A340 and A380 vs much more fuel-efficient twin engine airliners. Efficiency is the name of the GAME these days in commercial environments. And, I would never in a million years have ever thought that hovercraft could be used as icebreakers. That's really awesome!
