On the southern coast of England is a unique and fascinating place called the Hovercraft Museum, dedicated to the preservation and celebration of this rare form of transport.
We weren't sure what to expect, after all the museum's only open one day a week part of the year. For the full story behind our tour, check out The Hovercraft Museum is a miracle of floating metal machines, and we're big fans.
The first stop was the workshop, where many hovercraft were in the process of being restored.
The first production light hovercraft, the Hoverhawk. This is one of three the museum is restoring.
One of the only pieces left of the first SR.N4, Princess Margaret. It was scrapped in 2018.
A MkII Hoverhawk, from 1969. Heavily restored and updated at the museum, it now features the gas turbine APU from a Harrier jump jet, which should give it rather spirited performance. Land and sea testing are due to begin in 2020.
A Hover Rover, built in Canada. Rare in in Britain, and even rarer elsewhere, this is a cargo version with space behind the cockpit to carry supplies.
A variable pitch propulsion fan.
An American-made Hovertechnics Hoverguard 800. These were stationed at Heathrow airport in case an aircraft had to ditch in the marsh near the runways. They would rush out and deliver life rafts to the survivors.
This is HD2, a testbed for new designs and technologies by Hovercraft Development.
One of the museum's volunteers working on the Osprey 5 search and rescue hovercraft of the Association of Search and Rescue Hovercraft, Gosport Branch.
The BH.7 was intended for military use and was evaluated by the Royal Navy for 13 years in various roles.
Depending on the role and the arrangement, the overall layout would vary. In this case the wardroom is on the port side, with a galley aft.
The BH.7 could travel for 11 hours or more, depending on the mission, so the crew needs a kitchen.
An alternate arrangement would have the command crew in the center compartment, with soldiers sitting in each side compartment.
The BH.7 was well suited for antisubmarine and antinaval mine missions.
The big cylinder on the right is the container for the Plessey Speedscan sonar.
In yet another arrangement, up to 170 troops, plus up to three Land Rovers, could all get crammed inside for fast amphibious transportation.
Up a short ladder in the middle of the cargo area (or a long reach with a selfie stick), is the control cabin. Three men, two pilots and a navigator/radar operator had a commanding view from here.
Though not put in production for the Royal Navy, Iran bought six in the 70s. It's widely assumed these are stored or scrapped due to their age and the inability of Iran to get spare parts due to trade embargoes.
The museum's BH.7 is the original and well tested prototype. This craft also made it from here all the way up to the Arctic Circle.
Princess Anne is the largest civilian hovercraft ever built, and only slightly smaller than the largest military hovercraft, the Zubr-class.
Of the 6 SR.N4s built, this is the sole survivor.
The SR.N4 connected Dover, in the UK, with Boulogne, in France. This trip took about 35 minutes, depending on the weather. There was also a route between Ramsgate and Calais.
In their final form, the SR.N4s could carry over 60 cars and 400 passengers.
It was the jet age, and the interior of the SR.N4 had an aircraft vibe to it.
It's said that the real death knell for the cross-channel hovercraft service, and the SR.N4, was the end of duty-free shopping onboard.
Pay a bit extra and you got a table.
At the back of the craft are massive doors to facilitate faster loading and unloading.
One of the huge lift fans.
The SR.N4s were in service between 1968 and 2000. The Anne's sister ship, Princess Margret, was featured in Diamonds Are Forever.
The cruising speed of the SR.N4s was around 69 mph (111 kph). With no cargo or passengers, top speed was around 96 mph.
While the crossing usually took 35 minutes, on one favorable day in September 1995, this very craft did the crossing in a record 22 minutes -- a record that still stands for a car-carrying vessel.
They're still restoring the galley, which was on the port side, aft.
The edge of one of the huge ducts to channel air underneath the craft.
Some of the many electronics and wires needed to keep the SR.N4 hovering.
The control cabin for Princess Anne is off limits, but adjacent is the nearly identical control cabin for the Swift, the second SR.N4 built. Upfront would be a pilot and a first officer, who doubled as a flight engineer.
Not being the most graceful handling machines, radar was used to look out for anything that needed to be avoided.
The radarman had his own seat in the back of the control cabin.
A few decades after James Bond rode on Princess Anne, hovercraft were used far more extensively in Die Another Day. This is one of the Osprey 5 MKIIs used in the filming.
Despite the numbering, the SR.N5 actually flew before development started on the much larger SR.N4.
This SR.N5, believed to be the last survivor, was a training craft.
Only 14 SR.N5s were ever built, including seven by Bell in the US. An updated and stretched version became the far more successful SR.N6.
The Winchester-class SR.N6 was the first commercial hovercraft and was widely used and widely successful. This is the prototype.
In stretched form the SR.N6 could carry 58 passengers, similar numbers as a bus.
Navy fixed-wing and helicopter pilots were early recruits to fly hovercraft, which is logical.
This is also an SR.N6, but an evolution of the original design with two smaller props instead of one big one. The smaller props, in this case, producing less noise than the single larger one. This is the oldest operational hovercraft in the world.
This is a Griffon 2000TD, which comes in both civilian and, as you see here, military variants.
I wasn't sure what to expect with the Hovercraft Museum, but it turned out to be a fantastic place to visit. These are unique machines, and I'm glad to see them being preserved.
During the summer and fall, the museum is open on Saturdays. For more about the hovercraft you've seen, the museum and our visit, check out The Hovercraft Museum is a miracle of floating metal machines.
