Any respected small hovercraft manufacturer will have a detailed environmental assessment report that can be freely distributed. Such a report must address the issues of nuisance by noise, safety concerns to spectators, effects on habitat wild life and the possibility of pollution.
Noise is a particular concern as a large propeller is used to provide lift and forward thrust. This is driven by a petrol engine, either two or four stroke, and as such are inherently noisy. It should be noted that a comparison might be made between a personal hovercraft and other pleasure or leisure vehicles being used in the same vicinity. For example, by the sea shore, high powered motor boats are very popular, as are jet skis. Such a study should indicate the decibel ratings compared to these other vehicles.
Pollution is obviously a very strong point, also the effects on natural habitats. On the good side, there are no propellers in the water, so oil doesn't go into the sea. Generally, the engines are contained over the hull compartment and kept dry. For life under the sea or lakes, a noisy propeller thrashing around is more more disruptive to fish life than an air cushioned vehicle which floats over the surface. The question must be asked if any more man made vehicles should be introduced to our delicate environment at all in these times of environmental tipping points?
Safety is a major concern for hover craft manufacturers and design, not only for the pilots and passengers, but also for people looking for a hovercraft for sale. After all, it is quite an exciting spectacle. Modern craft hulls are made from high impact plastic or fiber glass. Glass fiber does tend to split if the hull hits a solid object, such as a rock in it's path. Despite this, many racing hovercraft use this type of construction. The overall construction is light for speed and risks of crashing are all part of the sport.
Such an attitude just won't do for the family man looking for an exciting experience to share with his family. In this situation safety is top priority and not a 'nice to have' feature at all. A slower craft with a thicker hull made from robust material is far preferable to a material that may split and crack under pressure. Expanded polypropylene and similar plastics are revolutionizing the industry and manufacturers of small light personal hovercraft are springing up all over the place.
