hoverkraft ima potisak zraka od podloge, i "odguriva" se od podloge...
slično radi i avon, no ipak postoji razlika...

ne bas.
propele ispod hoverkrafta sluze primarno za stvaranje zracnog jastuka tj. za eliminaciju tj. smanjenje trenja podloge (vjerovali ili ne, za isto sluze i kotaci).

Design
Hovercraft have one or more separate engines (some craft, such as the SR-N6, have one engine with a drive split through a gearbox). One engine drives the fan (the impeller) which is responsible for lifting the vehicle by forcing air under the craft. The air therefore must exit throughout the "skirt", lifting the craft above the area on which the craft resides. One or more additional engines are used to provide thrust in order to propel the craft in the desired direction. Some hovercraft utilise ducting to allow one engine to perform both tasks by directing some of the air to the skirt, the rest of the air passing out of the back to push the craft forward.

A ako te muci bas taj hoverkraft, uzmi za primjer ona splav za mocvaru sa velikom elisom za pogon... stvar savrseno funkcionira i na rijeci.
