No picture Hagglunds BGBV 82 ARV (Armored Recovery Vehicle)

Like the BARV, this would be a dammed handy thing to have around: it has a dozer blade, a huge winch, a small crane, and an open-topped cargo bay capable of holding a tank engine.
It's fully amphibious, achieving 8 km/h propelled just by it's tracks, which is pretty good.

The same company's PBV 302 APC has a similar capability which is, apparently, due to a combination of special tracks and carefully designed track guards.

A related vehicle is the Brobv 941 - the world's only amphibious bridge laying vehicle. The bridge (normally carried and launched from above the hull) is buoyant, and is towed behind the vehicle when it swims.

The info was send in by Harold Smith.

HALF SAFE Half Safe (1947)

Special page

Frederick Benjamin (Ben) Carlin (1912-1981) was born in Northam, Western Australia. He had seen amphibious Jeeps in India during the war and decided that one could drive, and swim, around the world. After the war he went to America determined to buy a Jeep and to make such a trip. He also married Elinore, an American, who despite being highly susceptible to sea-sickness sailed out with him on this trip.

He did drive and sailed all the way around the world!!

He is the only one who ever did this!!!

He also hold the record for the smallest motorized ship to cross the oceans.

James, a mechanical engineer in California has revived this project, since the original inventor has passed away.

The wheels on this vehicle retract in the water to reduce friction for increased speed.
The goal is to operate on land at up to 130 and in water up to 60 km/h

The rear view picture shows the Berkeley jet drive and it is driven by PTO.

Heking 2016

This company makes Amphibious Excavators in many shapes.

Applications: - Swamp work - Deepening of waterways and river deltas - Dredging - Landscaping - Digging up pipelines - Maintenance and cleaning of rivers, lakes, shorelines, ponds, etc

Seeing those tracks being moved into a container takes my memory back to the times I was young and was trying to fit a round peg in a square hole. ;-)

Hewitt Hewitt (Stan) (2003)

Hewitt's prototype, is a 17-foot amphibious vehicle that looks like a bathtub with the tracks of a tank.
It surprised Hewitt with a water speed over 50 km/h in the calm waters of Tongass Narrows.

The double-hulled boat is covered with 3D16-inch aluminium. The pivoting track system took some trial and error.

The biggest problem was trying to get these tracks to come up and down gracefully. It works with a two-arm hydraulic system to pivot the twin track assemblies, which use nylon rollers and have only two bearings apiece.

Hidromobile 1914 Hidromobile (1914)

A Los Angeles corporation is preparing to put on the market a remarkable combination of the auto-mobile and motor boat, invented by W. C. Mazzei, E. E., of New York City. This machine, which will sell for the same price as a high grade auto-mobile of the usual type, is intended particularly for use by travelers, who must cross streams and flooded areas.

In Popular Electricity and Modern Mechanics September 1914 there was an article.

W. C. Mazzei, E. E., of New York City is likely the same as William Mazzei from Los Angeles
That was involved with the Hydro-motor.

An especially ingenious feature of the Hidromobile is the arrangement of springs, whereby each wheel meets road inequalities without affecting the opposite wheel or admitting water to the body of machine.

These days that is called independent suspension.

Higgins Boat Company build many Amphibious vehicles for survey and rescue in the swamps of Louisiana.

Length: 11000 mm height: 4500 mm

It was more boot than vehicle with the 2 axles with 4 chain driven wheels in the middle.

To complicate matters in later days tracks where added as can be seen in de second photo.
On the 4th photo where the Beachmaster is put on rails for army testing the tracks are still missing.
It had a winch at the front.

Higgins Swamp Buggy (1940 1941) also called the "March Buggy?'

Higgins Boat Company build an Amphibious vehicle for survey and rescue in the swamps of Louisiana.
The price at the time was $6000

Engine: air cooled 40 hp
Gearbox: 5 speed
Length: 5000 mm width: 4000 mm Height: 3300 mm
Winch: 1 on front and 1 on the rear.

It has skid steering and the front axle has a center pivoted joint to give a limited agricultural movement to follow the terrain.

This one was tested by the US army in 1948 its name was then "Swamp Skipper model 5"
Each of the 2400 mm chain driven wheels had 2 stepper units to increase the footprint.
The military test was not successful.
NO power, NO speed and NO space to put a load.

According to "Mechanix Illustrated the "Swamp Skipper" came into the hands of Bill Oliver who used it for hunting in Everglades, she was then named the "Swamp Cadillac" and there the trail ends.

Hill head (2008)

The amphibious boat is from Hill Head and was built by the owner from scratch.
The caterpillar tracks retract into the hull.
That is all that I know.

On a shingle beach at Hill Head it goes up and down the beach with ease where a standard Sealegs does not go.

The owner parks in his garden and is in/out of the water in minutes.

In January 1999 and June 2000 the British "BIKE" Magazine published an article about the Amphibious Challenge they organized shortly before. Competitors had to "drive" 200 meters with there bike and there was 200 pound to win.

The magazine is in color but Kim Scholer has send me large B&W copy's by snail mail because he has no scanner.

The second AUB mechanical design contest: amphibious Vehicle

For propagation in water, a peddle-wheel-like attachments were put on the rear wheels. To increase the speed in water, they have added a propeller on the rear connected to the engine by a chain and sprocket mechanism.

Hongjun Amphibious research center (2002)

Wang Hong Jun is the chief designer he owns a motorcycle repair shop in Qian'an City.

The car has a double-skinned chassis with air pockets so it can float.
Weight: 1700 kg
Speed land: 150  water: 50 km/h ??

Water propulsion: 2 propellers
Over the year it keeps evolving and it has now also a jet drive.
I believe the propellers are disconnected.

In 2003 the builder has send me a (to big) email with photo's, but before it was possible to extracted them my hard drive crashed.

The car has a balancing system, that makes the car more stable in the water.
Not sure how that works or preforms.

Much information is still lost in translation from Chinese to English.
But we will get there in the end!

Humber Hexonaut GS 6x6 (1940)

Only 3 Hexonauts are ever built.
The only survivor is at the National Military History Centre in Indiana, USA.
She was on sale at Auctions America current location is unknown.

Engine: Two 14 hp Hillman
Gearbox: two Hillman transmissions
Each engine drives 3 wheels on one side by skid break steering
The rear engine drives also the winch.
Hummer Hexonaut engine layout
The two engines give the usual problems with steering:
Stalling of one engine makes it go in small circles.
Loss of power in one engine makes it go in larger circles.

Length 3750 width 1400 height 2000 mm
Two man crew
Weight: 3000 load: 1000 kg or 8 men
Water propulsion: by the wheels

It had to fit in a C47 Dakota to be air transportable.
The small width of the vehicle shows the maximum of the design specs.

It was used after WWII in Belgium by a logging company until the 1950s.
It was laid to rest/rust until in 1971 until somebody recognized it for what it was.

SWmark78 has written me:

The HWSTD is nothing more then the water test version of the USMC's up coming EFV/AAAV.

I believe under "AAAV" you have a picture of land test rig from the same project. The AAAV (Advanced Amphibious Assault Vehicle) has had its name change to the EFV (Expeditionary Fighting Vehicle), mainly to protect the guilty as the project will be a horrible flop that will probably doom the USMC.

The EFV/AAAV will suffer from:

-High Maintenance and Training costs
-Much Higher Fuel Consumption
-Inadequate Armour Protection
-Deafening should level in Troop Compartment
-No Gain in Land Mobility over newest version of current AAV, the AAVP7A1 RAM/RS (I don't know why they did not just go to AAVP7A2).
-More Vehicles needed per Platoon as each vehicle can carry only 18 Marines, instead of 21 to 25+ Marines
-Much larger Target then current AAVP7A1, which is a very large target itself.
-Lack of "Growth Room" as vehicle is internally cramped and over design weight as is .
