What does the acronym ATASD mean?

Amphibious Trimaran with Aero Static Discharge. Aerostatic discharge is the term for a layer of air pressurized to 750 – 1,080 Pa that serves the gap between ATASD’s inflatable floats and the terrain to reduce friction. The effect of the air cushion is visible on a level surface where ATASD hovers up to 4 cm (~1½”) above the ground.

What is Trimaran?

A trimaran is a multi-hull structure, similar to the pontoon boat with three  floats for advanced buoyancy, stability and heavy loads support on the water.

What is ATASD used for?

Where can ATASD go?

ATASD can operate over a wide variety of ground and water surfaces and safely access areas that are out of reach of conventional watercraft and vehicles. ATASD can operate in calm or swift water of any depth, in a waves up to 2m (6.5 ft), including flooded environments full of debris and underwater obstacles.

In addition, ATASD can travel over  sandbars, mudflats, muskeg, snow and ice – as well as short distances on paved surfaces. ATASD is not designed to operate in steep terrain or where there are obstructions such as rocks and trees.

How fast can ATASD go?

During trials with 3-5 crew, ATASD reached speeds of 100 km/h on calm water and 140 km/h on ice. It is not an absolute speed limits of ATASD but  recommended that these speeds are not exceeded in regular operation. ATASD’s speed over ground varies depending on the grade and type of surface.

What is an operational range of ATASD?

Approximately 240-250 km. Standard fuel tank capacity is 80 liters.  ATASD fuel consumption depending of the payload and weather conditions is 25-30 liters per hour at the cruise speed of 60-65 km/h.  

Does ATASD negatively affect the environment?

Because ATASD has no underwater mechanical systems it does not disturb the water column, pollute or create a wake. Over ground surfaces the craft is supported by a cushion of air, ensuring negligible impacts to sensitive environments. ATASD is one of the most environmentally friendly craft in the world.

Is ATASD easy to operate?

Yes, the control station is set up very much like a car with a steering wheel and familiar instruments. The controls that are unique to ATASD are few; a throttle lever for the engine, longitudinal trim control and pontoon air pressure pump. ATASD training is provided at the factory or on-site by arrangement with a Transport Canada certified air cushion vehicle operator.
