no trace - environmental concerns
By applying the third generation hovercraft technology, in environmental sensitive regions, gain significant environmental benefits.

A conventional boat designed to carry 10-15 tons at 40 knots would require propulsion by diesel engines of 6000 to 10000 Hp.
- Our fleet of ACVs (depending on the application), achieves the same carrying capacity and speed by flying 1,5-2 meters above the surface of the sea, thus reducing surface friction that allows twin or four diesel engines propulsion of 3000 hp. The benefits can be summarized as following:

No Submarine Impact
Transference of propeller noise to marine life does not occur and does not have a negative impact on the submarine life.
Flora, fauna, seabed sediments and fish spawn are protected due to the total absence of any underwater turbulence or stern gear.

No Discharge
There is no discharge of diesel fuel, lubrication oil, gasoline or hot exhaust gases into the water.

No Wash
Hoverfast's hovercrafts generates almost zero wash. Beach-, jetty-, harbor construction erosion is avoided. The erosion is a major problem caused by conventional ferries and pleasure boats in the most sensitive regions.

Reduction of Noise
Due to the past ten years development of propeller ducts with close propeller tip clearance, the Hoverfast fleet is not noisier than equivalent twin engine conventional high speed boats with inboard or outboard propulsions. Independent noise tests has been carried out both in England, Sweden and Brazil recording acceptable levels.

No toxic antifouling
The hovercraft does not need any toxic antifouling paint to keep the bottom clean from vegetation. Toxic bottom paint has become serious problems in the most sensitive areas.
