Amphibious ATV


Amphibious ATV

Small off-road, and typically six-wheel drive, amphibious vehicles were developed in the early 1960s and quickly became popular in both the US and Canada. Once it established itself as a popular vehicle to enthusiasts and professionals worldwide, the concept of these vehicles earned its own classification, coining the term "all-terrain vehicle" - or "ATV". [http://www.route6x6.com/about.html] However, after the introduction of small three- and four-wheeled off-road motorcycles in the 1970s and 1980s, these have become more well-known as ATVs than the original vehicle type, leaving that type now known as AATV or Amphibious All-Terrain Vehicle.

History

ATVs were made in the United States a decade before 3- and 4-wheeled ATVs were introduced by Honda and other Japanese companies. After the presentation of the Jiger in 1961, numerous manufacturers offered a number of similar small off-road vehicles, that were designed to float and were capable of traversing swamps, ponds and streams as well as dry land. Because they were smaller and much simpler in construction than (amphibious) cars, they were much cheaper to produce and quickly gained considerable popularity. By 1970 there were almost 60 companies producing amphibious 6x6 vehicles. There was even a professional racing association dedicated to the 6x6, holding numerous competitions across the USA. These amphibious vehicles were originally called all-terrain vehicles - or "ATV"s.

In the early 1970s however there was a rapid decline in sales of this type of ATVs, forcing most manufacturers to cease production. Reasons were:
* the 1973 oil crisis prompted many North Americans to tighten their belts and spend less on recreational vehicles.
* the introduction of the 1970 Honda ATC90 threewheeler offered a fun alternative at some $600 / $800, when a 6x6 would cost $1,500.
* The simple construction of the original ATVs attracted many companies that were interested in making a quick buck, but underestimated the engineering needed, leading to poor quality products, that gave the industry a bad reputation.

Only a small number of manufacturers of this type of vehicle remain today.

Characteristics

Although many differing variants have been developed over the years, and new ones are still being devised, most amphibious ATVs share most of the following characteristics. In contrast to today's ANSI definition of an ATV: "a vehicle that travels on low pressure tires, with a seat that is straddled by the (single) operator, and with handlebars for steering control", an AATV is intended for multiple riders, sitting inside, and will usually have steering wheels or control sticks rather than motorcycle-type handle bars as stipulated in the current definition. Typically constructed with a hard plastic or fiberglass watertight body"tub", AATVs usually have six or eight wheels - all driven - with low pressure (around 3 PSI) balloon tires, no suspension (other than what the tires offer) and no steering wheels. Directional control is accomplished through skid-steering - just as on a tracked vehicle - either by braking the wheels on the side where you want to turn, or by applying more throttle to the wheels on the opposite side. Most contemporary designs use garden tractor type engines, that will provide roughly 25 mph top speed. AATVs typically do not meet automobile legislation in most countries, and are therefore strictly Off Highway Vehicles.

Though not as fast as a straddled ATV, the amphibious 6x6 and 8x8 can be operated with precision at slow speeds, carry more passengers and cargo, and of course, has the ability to float. Although the spinning action of the tires is enough to propel the vehicle through the water - albeit slowly - outboard motors can be added for extended water use.
On land the combination of a large number of wide wheels and tires, low tire pressure and low vehicle weight, all result in exceptionally low ground pressure, high grip and off-road ability. Nevertheless for further enhanced off-road, snow and mud performance, optional tracks can be mounted directly onto the wheels.
