SEEP (GPA) (1942)

The Seeps intended use was to ferry soldiers from ships off-shore,
to drive up the beach and continue inland.
They were not very successful.

Fact is that the SEEP had 30% more weight, designed was 1200 kg but curb-weight was 1630 kg.
The Jeeps that were used in the sea sank if there were any significant waves.
To ad to the failure the extra weight of the hull made that they got stuck where a standard Jeep did not.

Look at the guy in the trailer (second photo) he keeps the water out with his arm. ;-)

Between 1942 and 1943 12777 or 12778 where build, the (known) highest dash number is GPA12777

383 where sold to England
21 where sold to Canada
Over 3000 where sold to the USSR under the Lend-Lease program
The USSR build a 68 of them under the name NAMI-011 (GAZ 011).
They later build a better one the name GAZ-46.

Engine: 4-cyl. side valves 2,199 cc 54/60 hp
Gearbox: 3 + 1
Transfer-box: 2 speed
Length: 4620 mm width: 1630 mm height: 1750 mm
Weight: 1630 kg load: 400 kg
Speed: land: 104 km/h water: ....

Maybe she was not what she was meant to be!

BUT, a highly modified amphibious Jeep by the name `Half-Safe'
crossed the Atlantic ocean in 1950 and continued to circle the world.
Her dash number was GPA1239

Seiga Seiga (2004)

The Seiga low ground pressure vehicles are hired out for use on sensitive areas.

Seiga are amphibious go anywhere vehicles with a ground pressure of less than 1.5 lb/sqin when loaded and with deck areas from 13 feet x 10 feet and a load capacity of 1-2.5 Tons depending on conditions.

Sherman DD swimming tank
Sherman DD swimming tank (1945)

DD stands for duplex drive. The tank is almost a normal Sherman except for the canvas screen on top of the tank to give it buoyancy and the 2 propellers at the back.

When a float the top of the tank is 1000 mm below the surface of the water. The crew with the exception of the driver stays on the top of the tank. The driver sits in the tank and has a very primitive breading apparatus, With just 300 mm free board only a mad man wood sit inside the tank without a breading device.

The screen could be erected in 15 minutes
and put down in seconds.

The screen had metal hoops for support and by inflating 36 vertical rubber tubes with compressed air from bottles the canvas curtain got rigidity.

On the rear of the tank at the tank's tracks, sprocket wheels drove sprocket wheels that gave power to the propellers. Water speed was 7 km/h

The commander and the driver could steer in the water, but the commander stood on a platform on top of the turret, that way he could see over the skirt, and he then steered the tank with a large lever.

The Tank museum in Dorset England has 1 Sherman DD that is complete with the original canvas top.
But she can't swim any more.

The DD tanks were one of the many specialized assault vehicles, known as Hobart's Funnies

The propellers can be moved upwards and out of harms way (hydraulic?).

At D day the waves where 2000 mm high.
That was almost 7 times the design height.
Not a nice thing to think about.

693 Sherman DD where made from march 1944 to February 1945.
Only 10 are know to survived in good condition

An other DD tank is the Valentine.
The DD prototype is the Tetrarch DD light tank.





Sherp 2016

The company was established in the year 2012, partnering up with Aleksey Garagashyan while testing the ATV SHERP prototype.
The goal was to construct a vehicle, that had no equivalent in going places.
In the year 2015 after 3 years of development, they have launched the ATV SHERP into mass production.


Patented tires, climes from the water onto the ice
Patented tire pressure regulating system

Friction steering, 4 separate disc brakes to increase reliability
Fuel system designed to operate a long time at critical angles without fuel starvation.

Load water: 1000 kg
The ATV SHERP is manufactured in Saint-Petersburg and available in two options:

Standard (pickup with a tent)
Kung (Hard top with a choice of colors

The interior can easily be changed.

Snail Systems

Snail Systems

It is amphibious and it is "self" propelled
Stays in contact with the earth, more or less. ;-)
It just needs a place on this site.

Is a low cost system that enables persons to move around, change their whereabouts and live in various environments.
One unit supplies space for one person. It is mobile both on land and water.

One person can move it slowly, either by pushing it like a wheel, walking inside it or on top of it.

In the water you need to use a peddle for propulsion. ;-)
Snow-boat Snow-Boat

The snowboat is an amphibious vehicle for Snow and water.
It is made of a boat hull and a snowmobile

The track can propel the vehicle in the water but an outboard will do a better job.

A PKW in Germany is a normal car!
In the seventies it was even legal to drive it on the HIGHWAY. !

Engine:  430 cc 2-cylinder 2-stroke 25 PK

Gearbox: torque converter with a reverse gear
Speed: 48 km/h
Fuel tank: 24 L Range: 120 km

The other wheels break also because of the transmission chains

. The wheels are rigidly attached to the body a smooth ride is ensured by the low pressure wide-tubeless tires.
There are 15 known to be in Germany and maybe 16 in the whole world.

Steyr-Daimler-Puch AG., Steyr, Austria. Steyr-470 RSO/01 based full-track amphibian

This Steyr has a cabin and a cover over the loading bay

This was the tracked tractor developed at the same time as the Radschlepper Ost for service in snow and mud conditions of the Eastern Front during the war.

It was developed by Steyr during 1942 and used the transmission of the standard 1 Engine: V8 designed by Mr. Ferdinand PORSCHE.

Amphibien-Autoporter (1960 ?)

I just HAVE to list this. ;-)

Amphibien-Autoporter is the German name.

It is a one (1) wheel car trailer
But by law NOT a trailer, so NO MAX TRAILER SPEED.

Originally designed for a VW Beetle.
In the winter you can fit sky's.

In summer you can use it as a boat. ;-)

This vehicle was for sale on Ebay.

Stridsvagn 103 Main Battle Tank (1967)

It is amphibious after 25 minutes of preparation. A floatation screen needs to be erected around the upper hull. Like the Sherman DD
This was the first practical turret less MTB to be developed.
290 where build.

Engine main 290 hp Detroit Diesel
Engine secondary: 490 hp Boeing 553 gas turbine.
The combined output of the both engines was better than the normal MBT's with heavier engines that used much more fuel.

The engines are located in the front to give additional protection to the crew of three, who are contained entirely within the hull.

The third man was placed in the rear of the hull, facing rear, with a full-driver system set up allowing the vehicle to be piloted in reverse driving in the same way as the froward driving was done.

Aiming the gun is done by adjusting the suspension system, see the Lego tanks. ;-)

Subaru. It was called Aquacar.

This is an amphibious rumor. It is possible that it is the Sealander MK2

The build

The jet
Suboataru (2010)

It was build by Shawn Pisciotti in his garage

The donor car was a 1991 4WD Subaru Justy 5 speed. 4 door hatchback.
Now it's a no door open top.

The original 3 cyl engine, the frame and drive train are almost untouched.

The first set-up for water drive was a 4 horse Briggs engine with a propeller.
That did not work out nice.

A big(er) jet-ski engine and impeller jet worked fine.

It does 15 km/h in the water

Suboataru has his own website




SuKi  (Su-ki) (1943)

A firm that later became Toyota build this truck from the non amphibious
KC truck the Amphib was known as KCY.

Japanese Amphibious 4x4 Truck
Engine: 6 cylinder 63 HP petrol
Gearbox 4 speed
Transfer-box 2 speed
Length: 7620 width: 2220 height: 2200 mm
Weight : 2700 load: 1400 kg
4 wheel drive with high ground clearance
198 where build from Nov 1934 to Aug 1944
It was based on Toyota 4x4 Truck "To-Ki"
At the time Toyota had a different name.

It had a P.T.O. driven propeller on the rear but no rudder
The front wheels did the steering in the water

It was used much on the Pacific islands.
Several where captured at Tinian.

But as known by me:
Non are in a museum or in private hands.

Suzuki Grand Vitara (2011)

This is NO Amphib.  I'm sorry, IT IS NOT,

It is an advertisement object on the SEMA for Suzuki Marine.
That is a part of Suzuki that made outboards e.t.c.

The bottom under the engine is open, and even if it was closed.
There is not enough lift at the front, she will float with her nose under water!
